00:00:01.510 greetings viewers Aerith car guy here 00:00:03.84000:00:03.850 back again with another well I guess I 00:00:06.36000:00:06.370 can't really call this a repair video 00:00:08.04000:00:08.050 I'm gonna call it an informational video 00:00:10.53000:00:10.540 not so much an infomercial because I'm 00:00:12.69000:00:12.700 not trying to sell you something I'm 00:00:14.33900:00:14.349 just trying to perhaps put out a little 00:00:16.32000:00:16.330 bit of information that might be useful 00:00:17.94000:00:17.950 to you at some point in time 00:00:19.62000:00:19.630 today's topic thermostats now 00:00:22.59000:00:22.600 thermostats perform a very important 00:00:24.36000:00:24.370 function in your engine more important 00:00:27.15000:00:27.160 than a lot of people I think realize 00:00:29.00000:00:29.010 thermostats can make or break your day 00:00:31.62000:00:31.630 in many ways now most of you know of a 00:00:34.44000:00:34.450 couple of the most common failures of 00:00:36.21000:00:36.220 thermostats in fact there are really 00:00:37.56000:00:37.570 just two things that can happen one the 00:00:40.23000:00:40.240 thermostat itself can remain closed and 00:00:42.69000:00:42.700 if it remains closed and does not allow 00:00:44.67000:00:44.680 coolant to circulate through the 00:00:45.84000:00:45.850 radiator well then you get an overheat 00:00:47.52000:00:47.530 situation the other type failure is that 00:00:50.72900:00:50.739 it gets stuck in the open position if 00:00:53.16000:00:53.170 it's stuck in the open position then 00:00:55.06900:00:55.079 maybe you never really get heat your 00:00:57.27000:00:57.280 engine never comes up the temperature 00:00:58.92000:00:58.930 and well that can also cause all kinds 00:01:02.13000:01:02.140 of other problems in fact I know some 00:01:05.03900:01:05.049 people or some people have said to me 00:01:06.56900:01:06.579 that they've removed the thermostat from 00:01:08.60900:01:08.619 their vehicle and just went on their 00:01:10.80000:01:10.810 merry way this is the exact wrong thing 00:01:13.59000:01:13.600 to do particularly on a modern vehicle 00:01:15.59000:01:15.600 fuel injection systems are super 00:01:18.12000:01:18.130 dependent on engine temperature when 00:01:21.14900:01:21.159 they reach a certain temperature 00:01:22.42900:01:22.439 operating temperature is usually 00:01:23.96900:01:23.979 somewhere around 200 degrees let's say 00:01:25.62000:01:25.630 we'll just throw that out there the 00:01:27.80000:01:27.810 engine management system tends to 00:01:30.23900:01:30.249 monitor its own fuel consumption and it 00:01:33.48000:01:33.490 doesn't do that until it reaches that 00:01:35.21900:01:35.229 operating temperature when it does reach 00:01:37.67900:01:37.689 that temperature or and does go into 00:01:40.28900:01:40.299 what is referred to as closed loop it 00:01:43.23000:01:43.240 monitors its own emissions it also 00:01:45.08900:01:45.099 monitors its fuel consumption and tries 00:01:47.06900:01:47.079 to give it the best fuel economy 00:01:49.01900:01:49.029 possible if you remove the thermostat 00:01:51.44900:01:51.459 which is in essence the gatekeeper of 00:01:53.45900:01:53.469 the cooling system if you remove the 00:01:55.44000:01:55.450 thermostat what happens is you have 00:01:56.73000:01:56.740 unregulated coolant flow through the 00:01:58.62000:01:58.630 whole system and what this causes is the 00:02:01.10900:02:01.119 engine is never really up to temperature 00:02:02.55000:02:02.560 in fact temperature tends to fluctuate a 00:02:04.76900:02:04.779 great deal without a thermostat in the 00:02:07.23000:02:07.240 engine and as I said can cause problems 00:02:09.63000:02:09.640 with fuel economy 00:02:10.71900:02:10.729 I strongly recommend you run a 00:02:14.11000:02:14.120 thermostat in your vehicle and don't run 00:02:15.91000:02:15.920 without a thermostat even if you're in a 00:02:18.07000:02:18.080 warmer climate where you feel I don't 00:02:20.28900:02:20.299 need any heat or anything like that I'm 00:02:22.75000:02:22.760 just gonna go ahead and remove that 00:02:24.00900:02:24.019 thermostat and forget about it not 00:02:25.78000:02:25.790 necessarily a good idea let's uh head 00:02:28.18000:02:28.190 over to the bench we'll talk a little 00:02:29.44000:02:29.450 bit about the operation of the 00:02:30.72900:02:30.739 thermostat and its parts okay here's a 00:02:33.13000:02:33.140 little bit of a closer view of the 00:02:35.08000:02:35.090 thermostat this one is out of a Honda 00:02:37.44000:02:37.450 and let's talk a little bit about these 00:02:39.78900:02:39.799 parts the first thing I'm looking at is 00:02:42.36900:02:42.379 this little piece right here this is 00:02:44.61900:02:44.629 this is actually an air bleed when the 00:02:47.77000:02:47.780 thermostat is closed when you first 00:02:48.97000:02:48.980 start it up then there's no way for air 00:02:51.75900:02:51.769 to circulate through the radiator so it 00:02:53.28900:02:53.299 makes it very difficult to purge air 00:02:55.08900:02:55.099 from a cooling system with without this 00:02:58.86900:02:58.879 little valve here so this helps air pass 00:03:02.05000:03:02.060 through here while the thermostat is 00:03:03.81900:03:03.829 closed so that's safe for instance if 00:03:06.28000:03:06.290 you are bleeding a cooling system which 00:03:07.86900:03:07.879 I'll post a link to those in the 00:03:09.13000:03:09.140 description of how to do that and why 00:03:10.75000:03:10.760 that's important so that will help aid 00:03:12.91000:03:12.920 you in that circumstance and just a note 00:03:16.03000:03:16.040 if you have one of these and not all 00:03:17.74000:03:17.750 thermostats have these if you do have 00:03:20.25900:03:20.269 one of these because it is an air please 00:03:22.27000:03:22.280 make sure you install it towards the top 00:03:23.97900:03:23.989 when you install it into the engine 00:03:25.42000:03:25.430 because if you install it on the bottom 00:03:27.30900:03:27.319 you're sort of defeating the purpose 00:03:28.21000:03:28.220 because the air will rise to the highest 00:03:30.28000:03:30.290 part of the system next let's talk a 00:03:32.05000:03:32.060 little bit about the parts of the 00:03:33.49000:03:33.500 thermostat you see a giant spring here 00:03:35.86000:03:35.870 and that actually helps keep the valve 00:03:37.53900:03:37.549 closed you can sear on the outside here 00:03:40.00000:03:40.010 there's this little little truss that 00:03:42.33900:03:42.349 helps give that some stability but that 00:03:44.97900:03:44.989 actually helps close the thermostat now 00:03:46.87000:03:46.880 what actually opens the thermostat is 00:03:48.58000:03:48.590 this little well I guess that's copper 00:03:52.05900:03:52.069 on the inside there sometimes it's made 00:03:54.00900:03:54.019 out of brass or some other material but 00:03:55.65900:03:55.669 it's usually filled with a charge like 00:03:58.53900:03:58.549 perhaps a paraffin wax which expands as 00:04:01.99000:04:02.000 it gets warmer and as that expands that 00:04:04.72000:04:04.730 forces the thermostat to open up and as 00:04:07.36000:04:07.370 it opens up it allows coolant to flow 00:04:10.68900:04:10.699 through now there's two things that 00:04:12.43000:04:12.440 happen when that happens now when the 00:04:14.17000:04:14.180 thermostat is closed like this you might 00:04:16.08900:04:16.099 be wondering what this piece back here 00:04:17.56000:04:17.570 is for this piece back here helps close 00:04:20.22900:04:20.239 off the bypass as the thermostat is 00:04:22.48000:04:22.490 closed 00:04:22.93000:04:22.940 you still need coolant 00:04:24.29000:04:24.300 you late through the cooling system 00:04:25.65900:04:25.669 mainly through the engine block so what 00:04:29.11900:04:29.129 that does is as the as it's closed 00:04:32.05000:04:32.060 coolant can pass through here and still 00:04:34.24900:04:34.259 circulate through the engine block and 00:04:35.89900:04:35.909 not through the radiator it's only when 00:04:37.93900:04:37.949 the thermostat opens up that it allows : 00:04:39.86000:04:39.870 to circulate through the radiator to be 00:04:41.30000:04:41.310 cooled but there is a time during warmup 00:04:43.55000:04:43.560 where that's not necessarily required so 00:04:46.07000:04:46.080 as this opens up this part of the 00:04:48.92000:04:48.930 thermostat actually goes against the 00:04:50.89900:04:50.909 housing and closes off the bypass in the 00:04:54.05000:04:54.060 back of well could be the cylinder head 00:04:56.21000:04:56.220 could be the engine block it could be 00:04:58.12900:04:58.139 another as in the case of the Civic 00:05:00.05000:05:00.060 there's a separate thermostat housing 00:05:02.45000:05:02.460 that comes off of the back of the engine 00:05:04.67000:05:04.680 block and that's what this does it helps 00:05:06.80000:05:06.810 block that off so as the engine is cold 00:05:09.77000:05:09.780 with the thermostat closed you have 00:05:11.62900:05:11.639 circulation through the block as it 00:05:13.64000:05:13.650 warms up in the thermostat opens this 00:05:15.55900:05:15.569 closes off the bypass and allows the 00:05:17.74900:05:17.759 coin to circulate through the radiator 00:05:19.12900:05:19.139 to be cooled now let's take this a step 00:05:21.08000:05:21.090 further I'm going to show you how to 00:05:23.18000:05:23.190 check to see if your thermostat is 00:05:24.95000:05:24.960 opening properly one of the things that 00:05:27.95000:05:27.960 you'll note on the outside here is there 00:05:29.83900:05:29.849 is a temperature stamped on the outside 00:05:32.05900:05:32.069 there in this case that is a t2 C which 00:05:35.30000:05:35.310 would be 82 degrees Celsius which 00:05:37.45900:05:37.469 equates to about a hundred and seventy 00:05:39.64900:05:39.659 nine point whatever degrees Fahrenheit I 00:05:43.10000:05:43.110 know this because I looked it up on my 00:05:44.48000:05:44.490 iPhone app but that's the temperature 00:05:46.90900:05:46.919 that the thermostat should be opened so 00:05:49.21900:05:49.229 your thermostat may vary but it should 00:05:52.27900:05:52.289 have a temperature stamped on the 00:05:54.05000:05:54.060 outside of it so we're gonna put this in 00:05:56.33000:05:56.340 water that's heated up to that 00:05:58.18900:05:58.199 temperature and it should open up now 00:06:00.76900:06:00.779 I'm going to add another wrinkle into 00:06:01.90900:06:01.919 this and then I have an aftermarket 00:06:04.36900:06:04.379 thermostat for the same vehicle here now 00:06:07.07000:06:07.080 I've always advocated that original 00:06:08.77900:06:08.789 equipment which is here on the Left 00:06:10.05900:06:10.069 thermostats are better than aftermarket 00:06:12.20000:06:12.210 thermostats a thermostat is better than 00:06:14.77900:06:14.789 no thermostats so if you can only afford 00:06:16.10000:06:16.110 in a half a market get an aftermarket 00:06:17.62900:06:17.639 but if you are interested in getting all 00:06:20.68900:06:20.699 you can out of your thermostat I 00:06:22.10000:06:22.110 personally recommend original equipment 00:06:23.89900:06:23.909 thermostats as you can see the 00:06:25.45900:06:25.469 construction is very different in these 00:06:27.23000:06:27.240 two things they're the same size but the 00:06:30.17000:06:30.180 materials that they're made from and 00:06:31.45900:06:31.469 also you can see there's less of them 00:06:33.23000:06:33.240 there's less of this spring here 00:06:35.12000:06:35.130 and I'm gonna see if that has any 00:06:37.37000:06:37.380 bearing on how the thermostat itself 00:06:39.95000:06:39.960 operates so we're gonna put it to the 00:06:41.51000:06:41.520 test and see if I'm right about it or 00:06:43.04000:06:43.050 not here we have a nice little tin to 00:06:45.71000:06:45.720 heat this up and you can use you know 00:06:47.78000:06:47.790 just write your regular cookware I can 00:06:49.55000:06:49.560 use a pot whatever you just need to be 00:06:51.62000:06:51.630 able to have something that you can heat 00:06:53.03000:06:53.040 up to the temperature that as I said was 00:06:55.79000:06:55.800 printed on here and so we're looking for 00:06:57.29000:06:57.300 about a hundred and eighty degrees in 00:06:59.45000:06:59.460 this case for this thermostat now this 00:07:01.04000:07:01.050 isn't the best choice mainly you can see 00:07:03.68000:07:03.690 because it's actually leaking onto that 00:07:05.42000:07:05.430 seam but I think it will work for our 00:07:07.64000:07:07.650 purposes I've also used it in the past 00:07:09.20000:07:09.210 for this that's what all the burn marks 00:07:10.58000:07:10.590 are on the bottom here and I also found 00:07:12.41000:07:12.420 that heating it up with my propane torch 00:07:14.83000:07:14.840 just didn't do the job so I'm gonna use 00:07:19.13000:07:19.140 oxy acetylene anyway here's our baseline 00:07:21.37000:07:21.380 looks like today it's just a hair under 00:07:25.43000:07:25.440 50 degrees and I'm gonna put that right 00:07:28.07000:07:28.080 there but I'm also gonna go with the 00:07:31.04000:07:31.050 infrared so that we can try it out there 00:07:34.58000:07:34.590 and this says 44 degrees here we have 00:07:37.31000:07:37.320 the original equipment thermostat and 00:07:40.93000:07:40.940 next to it we're going to place the 00:07:43.82000:07:43.830 aftermarket thermostat and I'm gonna 00:07:46.10000:07:46.110 continue heat the water until we get up 00:07:47.87000:07:47.880 to 180 degrees look to see if they open 00:07:49.97000:07:49.980 up and well we'll take it from there and 00:07:53.18000:07:53.190 you also if you use like a pot that's 00:07:56.00000:07:56.010 really deep or something like that you 00:07:57.56000:07:57.570 don't want to use your fingers to take 00:07:59.12000:07:59.130 the stuff out there so you can use a 00:08:01.52000:08:01.530 pair of pliers such as this or you can 00:08:03.98000:08:03.990 tie a piece of wire around it or 00:08:05.54000:08:05.550 something like that and submerge it but 00:08:07.25000:08:07.260 mainly what you try to do is you're 00:08:08.36000:08:08.370 trying to verify its operation you want 00:08:10.31000:08:10.320 to make sure that it opens up at the 00:08:11.66000:08:11.670 proper temperature and it can close 00:08:13.01000:08:13.020 fully if you can do those two things 00:08:15.02000:08:15.030 you're good I mean I realized that 00:08:16.49000:08:16.500 thermostats are not that expensive 00:08:18.02000:08:18.030 and if you're gonna go through the time 00:08:19.52000:08:19.530 and effort to remove it from the engine 00:08:21.68000:08:21.690 you're likely going to replace it but if 00:08:23.78000:08:23.790 you want to know if that's actually what 00:08:25.37000:08:25.380 your problem is this will tell you that 00:08:27.65000:08:27.660 also I can say that for the most part 00:08:29.57000:08:29.580 many many many cooling system problems 00:08:31.85000:08:31.860 of the result of air and the cooling 00:08:33.20000:08:33.210 system so please check for that the way 00:08:35.57000:08:35.580 to check for that is in that video I 00:08:38.00000:08:38.010 post a link in the description to of how 00:08:39.86000:08:39.870 to bleed a cooling system 00:08:47.87000:08:47.880 we'll keep an eye on the temperature as 00:08:49.55000:08:49.560 we go now water is very good at 00:08:53.68900:08:53.699 conducting heat some people think that 00:08:56.99000:08:57.000 running a hundred percent coolant is the 00:08:59.12000:08:59.130 way to go and your cooling system in 00:09:00.80000:09:00.810 some cases actually it's not you're much 00:09:04.40000:09:04.410 better off running a mix of coolant and 00:09:06.23000:09:06.240 water if you want to know what mix to 00:09:08.68900:09:08.699 use in your application check on the 00:09:11.74900:09:11.759 back of the antifreeze bottle because 00:09:14.78000:09:14.790 usually they list mixture proportions 00:09:16.87900:09:16.889 it's normally 50/50 but in some cases 00:09:19.55000:09:19.560 you might need more protection and you 00:09:21.98000:09:21.990 might use a little more coolant and I'm 00:09:24.13900:09:24.149 doing it this way inside of water 00:09:25.72000:09:25.730 instead of doing it outside and just 00:09:30.29000:09:30.300 heating the thermostat up directly 00:09:31.84000:09:31.850 mainly because the original equipment 00:09:34.06900:09:34.079 thermostat has a rubber seal on it if 00:09:36.74000:09:36.750 you heat that up directly that rubber 00:09:38.96000:09:38.970 seal will likely melt and that will suck 00:09:42.17000:09:42.180 so I don't recommend heating them up 00:09:43.73000:09:43.740 directly Plus this is the real world 00:09:45.86000:09:45.870 this is where they live they live inside 00:09:47.30000:09:47.310 of basically hot water another thing to 00:09:50.05900:09:50.069 mention is that your radiator cap has a 00:09:53.38900:09:53.399 lot to do with what temperature the 00:09:56.54000:09:56.550 water boils that water boils at 212 00:09:58.79000:09:58.800 degrees Fahrenheit but actually at 99.9 00:10:02.78000:10:02.790 8 degrees Celsius hundred degrees 00:10:04.63900:10:04.649 Celsius for lack of a better word if you 00:10:06.98000:10:06.990 put pressure on the system you can 00:10:10.00900:10:10.019 actually raise the boiling point of the 00:10:12.49000:10:12.500 mixture so in the case of the cooling 00:10:16.46000:10:16.470 system for every pound of pressure 00:10:18.19900:10:18.209 that's listed on the kit on your 00:10:19.63900:10:19.649 radiator cap it raises the boiling point 00:10:22.22000:10:22.230 of the mix to degrees so for every pound 00:10:25.61000:10:25.620 of pressure on there that's that's 2 00:10:27.13900:10:27.149 degrees higher that that that mixture 00:10:30.19900:10:30.209 will boil at so if you have say a 15 00:10:32.50900:10:32.519 pound cap that will raise the boiling 00:10:35.68900:10:35.699 point of that mixture 30 degrees so 00:10:39.35000:10:39.360 instead of 212 would be 242 should be 00:10:43.61000:10:43.620 opening them up any second 00:10:46.55000:10:46.560 yep they both just opened up for about 00:10:52.47000:10:52.480 190 but they're both open now okay looks 00:11:04.95000:11:04.960 like 185 but here we have the original 00:11:09.45000:11:09.460 equipment thermostat which you can see 00:11:11.94000:11:11.950 is open there let's watch it as it cools 00:11:18.89000:11:18.900 we can see it slowly start to close 00:11:21.66000:11:21.670 because that's exactly what it's 00:11:22.98000:11:22.990 supposed to do it needs to close as well 00:11:24.48000:11:24.490 remember a thermostat that's stuck open 00:11:26.97000:11:26.980 is equally damaged damaging is one that 00:11:31.08000:11:31.090 is stuck closed and causes an overheat 00:11:34.34000:11:34.350 and we can see it closes up fairly 00:11:37.29000:11:37.300 quickly that one's now just about closed 00:11:41.94000:11:41.950 I can actually hear it 00:11:46.64000:11:46.650 closing up now let's check to see if one 00:11:50.19000:11:50.200 it will open back up but we can also 00:11:53.07000:11:53.080 check our aftermarket thermostat you can 00:11:57.30000:11:57.310 see this one is very easily to see that 00:12:00.33000:12:00.340 that one's wide open but that one's 00:12:01.92000:12:01.930 closing almost immediately so it does 00:12:05.61000:12:05.620 act differently look how quickly that 00:12:07.77000:12:07.780 closed up it's just about there right 00:12:10.40000:12:10.410 now so this one closes up almost 00:12:15.63000:12:15.640 immediately so the aftermarket 00:12:19.14000:12:19.150 thermostat does have some different 00:12:20.64000:12:20.650 characteristics but as far as when it 00:12:22.14000:12:22.150 opened it opened it 180 degrees just 00:12:25.41000:12:25.420 like it's supposed to so it did that 00:12:28.02000:12:28.030 this one opened back up slightly but not 00:12:30.42000:12:30.430 that much I'm assuming that my water is 00:12:36.57000:12:36.580 cooled down quite a bit since then since 00:12:38.88000:12:38.890 I stopped adding Heat yeah I'm at about 00:12:41.97000:12:41.980 178 so I'm just I'm just below the 00:12:44.67000:12:44.680 temperature threshold that these things 00:12:46.23000:12:46.240 are supposed to open up at but yeah the 00:12:51.57000:12:51.580 aftermarket thermostat performed almost 00:12:54.15000:12:54.160 identical to the original equipment but 00:12:56.31000:12:56.320 it certainly it opened a lot faster and 00:12:58.95000:12:58.960 a 00:12:59.55000:12:59.560 a lot faster so I'm not sure if that's a 00:13:03.30000:13:03.310 good thing or a bad thing but it did act 00:13:04.86000:13:04.870 differently and that's that's my point 00:13:06.86900:13:06.879 it's not a bad thing to use an 00:13:08.63900:13:08.649 aftermarket thermostat but they do have 00:13:10.71000:13:10.720 different characteristics than original 00:13:12.32900:13:12.339 equipment thermostats the gatekeepers of 00:13:15.60000:13:15.610 the cooling system do you need them yes 00:13:18.32900:13:18.339 you do need them 00:13:19.65000:13:19.660 you can't just remove them and throw 00:13:21.29900:13:21.309 them away when they're not working or 00:13:23.28000:13:23.290 you suspect that they're not working you 00:13:25.04900:13:25.059 can throw them in a pot of boiling water 00:13:26.97000:13:26.980 of the given temperature that's printed 00:13:30.60000:13:30.610 on the outside of the thermostat and it 00:13:31.98000:13:31.990 should open at that temperature and it 00:13:33.42000:13:33.430 should close up all the way completely 00:13:35.67000:13:35.680 so if the thermostat is partway open 00:13:37.55900:13:37.569 when you remove it and it's below the 00:13:39.72000:13:39.730 threshold temperature then you know you 00:13:41.48900:13:41.499 have a faulty thermostat that's stuck 00:13:42.96000:13:42.970 open symptoms of that are probably your 00:13:45.72000:13:45.730 heats not working all that great 00:13:47.00900:13:47.019 something along that nature and 00:13:49.43900:13:49.449 obviously if it's stuck closed you'll go 00:13:51.15000:13:51.160 into an overheat situation so the only 00:13:53.36900:13:53.379 other thing that I can think to mention 00:13:54.54000:13:54.550 aside from the fact that this blocks off 00:13:56.61000:13:56.620 and allows the coolant to stay 00:13:59.42900:13:59.439 circulating through the engine when the 00:14:00.84000:14:00.850 engines cold and blocks off the bypass 00:14:02.93900:14:02.949 when it warms up is that in addition to 00:14:05.22000:14:05.230 that the input hose for your heater core 00:14:07.98000:14:07.990 is often positioned just behind the 00:14:10.61900:14:10.629 thermostat that's so that that coolant 00:14:13.43900:14:13.449 begins to circulate through the healer 00:14:14.85000:14:14.860 heater core almost immediately upon 00:14:16.74000:14:16.750 startup that way you get heat inside the 00:14:19.29000:14:19.300 cabin as quickly as possible so they 00:14:22.49900:14:22.509 designed the system that way there's 00:14:23.67000:14:23.680 also heater control valves and those 00:14:25.07900:14:25.089 kinds of things but but normally the 00:14:27.86000:14:27.870 input for the heater core on your system 00:14:30.66000:14:30.670 is taken somewhere from behind this 00:14:32.85000:14:32.860 thermostat but most of the time I will 00:14:35.22000:14:35.230 say that if you have cooling system 00:14:36.48000:14:36.490 problems the first thing to do is check 00:14:38.81900:14:38.829 for air in the cooling system can't tell 00:14:40.43900:14:40.449 you how many times that has caused 00:14:42.74900:14:42.759 issues with cooling systems either 00:14:45.11900:14:45.129 overheats or your feet isn't working 00:14:47.54900:14:47.559 properly especially if you've just done 00:14:49.86000:14:49.870 a service like you've replaced a 00:14:51.11900:14:51.129 radiator or perhaps the thermostat you 00:14:53.49000:14:53.500 need to be sure to purge the air from 00:14:55.37900:14:55.389 that system 00:14:56.57900:14:56.589 I've got like a set of video on that 00:14:58.35000:14:58.360 I've also got I'm also going to have to 00:14:59.99900:15:00.009 do another video on how to bleed what a 00:15:02.16000:15:02.170 system with an expansion tank I should 00:15:04.67900:15:04.689 do one specifically on that because 00:15:05.97000:15:05.980 those are a little bit different anyway 00:15:07.41000:15:07.420 that is thermostats for you so I 00:15:10.32900:15:10.339 hope this information was useful to you 00:15:12.24900:15:12.259 it may help you diagnose or fix a 00:15:14.65000:15:14.660 problem that you might have and your 00:15:16.74900:15:16.759 vehicle or perhaps someone you know 00:15:18.66000:15:18.670 anyway I am Erik the car guy I can 00:15:21.91000:15:21.920 always be found 24 hours a day 7 days a 00:15:23.86000:15:23.870 week over at eric the car guy dot-com
