00:00:00.030 hi today I have a 7.3 that had two 00:00:03.64900:00:03.659 failed oil cooler or a cooler housing 00:00:06.20000:00:06.210 seal most likely but this video is not 00:00:09.29000:00:09.300 covering that I already have a video on 00:00:11.03000:00:11.040 the oil cooler on these this one's going 00:00:13.28000:00:13.290 to be covering contaminated cooling 00:00:15.25900:00:15.269 systems and a flush procedure that I use 00:00:17.18000:00:17.190 to get them out doesn't matter if it's a 00:00:20.08000:00:20.090 606 for diesel fuel or oil or a complete 00:00:23.90000:00:23.910 sludge buildup you can see it here it's 00:00:26.15000:00:26.160 covered in oil it takes quite a bit of 00:00:30.89000:00:30.900 flushing and you want to break it down 00:00:33.37000:00:33.380 so first thing we're going to do is 00:00:35.60000:00:35.610 drain it and after it's trained you want 00:00:38.03000:00:38.040 to pull the lower hose off to help so 00:00:40.43000:00:40.440 everything come out and the longer you 00:00:42.29000:00:42.300 leave it off and the warmer the engine 00:00:44.56900:00:44.579 is the better if you can if you're going 00:00:47.06000:00:47.070 to be working on it safer overnight all 00:00:49.79000:00:49.800 day or let it sit for days while you 00:00:51.61900:00:51.629 order parts drain it and pull the lower 00:00:53.84000:00:53.850 hose off so everything can slowly flow 00:00:55.63900:00:55.649 and trickle out into a waste bucket so 00:00:58.22000:00:58.230 let's go ahead and drain this one 00:01:15.50000:01:15.510 I have the leak fix so I have no more 00:01:20.80000:01:20.810 cross-contamination now we have to flush 00:01:23.30000:01:23.310 it out Ford will tell you to use a 00:01:26.09000:01:26.100 simple green which will work find it 00:01:28.58000:01:28.590 kind of expensive and then of course you 00:01:30.89000:01:30.900 want to make sure what's what you're 00:01:32.66000:01:32.670 allowed to do in your area as far as 00:01:34.61000:01:34.620 your environmental laws but what I do 00:01:37.34000:01:37.350 here because you want something low 00:01:38.81000:01:38.820 sudsing and also remember especially on 00:01:41.33000:01:41.340 a six-o straight water an engine would 00:01:43.85000:01:43.860 overheat so when I'm doing this before 00:01:46.82000:01:46.830 to recommend that you go in and command 00:01:49.40000:01:49.410 it on with the IDS at 1,200 rpms for an 00:01:52.46000:01:52.470 hour I take them on short drives but you 00:01:55.43000:01:55.440 do have to remember straight water will 00:01:57.23000:01:57.240 overheat if you use a sudsing so it'll 00:02:01.07000:02:01.080 also expand too much and how you build 00:02:03.20000:02:03.210 up pressure and causes problems so I 00:02:05.24000:02:05.250 just do short little drives to warm it 00:02:07.10000:02:07.110 up because it has to be of course the 00:02:09.74000:02:09.750 heat helps to release the oil and break 00:02:11.27000:02:11.280 it down so what I'll do is I'll just use 00:02:13.52000:02:13.530 a dishwashing liquid this one here it 00:02:15.56000:02:15.570 says it's tough on grease and it works 00:02:18.02000:02:18.030 pretty good whether it's this is just 00:02:19.52000:02:19.530 this generic store-brand cascade all 00:02:22.40000:02:22.410 that works good I put some water and a 00:02:24.62000:02:24.630 cup here and I'm going to take quite a 00:02:26.90000:02:26.910 bit and put it inside here I mean quite 00:02:30.47000:02:30.480 a bit a couple cups at least I'll put it 00:02:32.96000:02:32.970 in there with the water and I'll mix it 00:02:34.88000:02:34.890 even though it won't stay fully suspend 00:02:37.10000:02:37.110 it makes it quite a bit 00:02:38.84000:02:38.850 most I just want to make sure that I can 00:02:40.19000:02:40.200 get it to flow out of the cup I'm going 00:02:42.89000:02:42.900 to dump it in the cooling system I'll do 00:02:45.35000:02:45.360 that with probably almost half a box 00:02:47.24000:02:47.250 when it's really bad I'm going to put it 00:02:49.79000:02:49.800 in there may God and drive it around so 00:02:53.51000:02:53.520 I'm going to set the Box down here and 00:02:56.12000:02:56.130 start to mix this 00:03:40.97000:03:40.980 I also do have some water in the cooling 00:03:43.37000:03:43.380 system so this isn't just going to all 00:03:45.17000:03:45.180 collect on the bottom I'll go ahead and 00:03:47.21000:03:47.220 dump this in 00:04:02.72000:04:02.730 when it's real bad I'm going to do this 00:04:04.49000:04:04.500 a couple cupfuls to get it pretty much 00:04:07.16000:04:07.170 to get it pretty saturated here don't 00:04:10.40000:04:10.410 mix myself another cup 00:04:24.84000:04:24.850 I'm going to top it off risk the way 00:04:27.31000:04:27.320 here with water a couple things you've 00:04:29.62000:04:29.630 got to be aware of if it's one that has 00:04:32.49900:04:32.509 a heated control valve like back here 00:04:37.71000:04:37.720 you need to turn the heater on with them 00:04:41.65000:04:41.660 now not all units will have them there's 00:04:43.24000:04:43.250 six those are the seven threes not all 00:04:44.89000:04:44.900 of them have the heater control valve 00:04:46.30000:04:46.310 but if it does the heater must be on so 00:04:49.42000:04:49.430 the water circulates through the heater 00:04:51.15900:04:51.169 cord otherwise you just have it going 00:04:53.89000:04:53.900 through the block and you still going to 00:04:55.87000:04:55.880 have a lot of contamination in there on 00:04:59.74000:04:59.750 the top this went off and go out and 00:05:01.18000:05:01.190 drive it at light throttle and get it 00:05:02.65000:05:02.660 warmed up and get it circulating help to 00:05:04.30000:05:04.310 break down some of the oil that's in 00:05:05.74000:05:05.750 there just got back from the road test a 00:05:09.90900:05:09.919 few things I want to point out and I 00:05:12.67000:05:12.680 shut the engine off just so I don't have 00:05:14.17000:05:14.180 to talk over it but normally I wouldn't 00:05:15.87900:05:15.889 shut it off because right now so they 00:05:18.73000:05:18.740 just got back on the drive and shut it 00:05:20.11000:05:20.120 off the engines getting to be at its 00:05:21.90900:05:21.919 hottest point because without the water 00:05:24.70000:05:24.710 circulating it's just sitting there in 00:05:26.20000:05:26.210 the block getting absorbing all the heat 00:05:28.26000:05:28.270 so anyhow I have the engine off if you 00:05:32.08000:05:32.090 want to open and start to flush it as 00:05:34.65900:05:34.669 soon as it's cool enough for to be safe 00:05:37.18000:05:37.190 for you the hotter the better but also 00:05:39.58000:05:39.590 make sure it's safe for you before open 00:05:42.04000:05:42.050 the cap just a few pointers water boils 00:05:44.74000:05:44.750 at 212 degrees it's going to boil easier 00:05:47.50000:05:47.510 than what it did before when I had 00:05:48.90900:05:48.919 coolant in it and also never open a 00:05:51.21900:05:51.229 cooling system if you can't squeeze the 00:05:53.46900:05:53.479 upper hose also this one's not so hot 00:05:56.17000:05:56.180 let's see I can touch the hose still so 00:05:58.93000:05:58.940 I'm going to go ahead and be aware it is 00:06:00.76000:06:00.770 pressure in it from the hose I'm going 00:06:02.98000:06:02.990 to start it back up let it run for a 00:06:04.39000:06:04.400 second which will help to cool it down 00:06:05.52900:06:05.539 and then slowly open the cap and start 00:06:09.12900:06:09.139 to drain it so I can do the flush also 00:06:11.98000:06:11.990 when I'm draining it I'm over a place 00:06:14.40900:06:14.419 here that has a water collection that 00:06:16.60000:06:16.610 can tip has a separator in there for the 00:06:18.87900:06:18.889 oil in the water so make sure wherever 00:06:21.39900:06:21.409 you're flush into that that you're 00:06:23.20000:06:23.210 allowed to do it 00:06:46.03000:06:46.040 pull the heater hose off let it drain 00:06:48.70000:06:48.710 I'm going to run fresh water through it 00:06:51.17000:06:51.180 with it running with it off I'm going to 00:06:54.29000:06:54.300 shut the engine off shut the water off 00:06:55.94000:06:55.950 let it drain down let it fill back up 00:06:57.92000:06:57.930 that way we try to get the water 00:06:59.69000:06:59.700 traveling everywhere we can with the 00:07:02.48000:07:02.490 engine running it'll travel in certain 00:07:03.92000:07:03.930 directions with it off it's going to let 00:07:06.11000:07:06.120 it go in other directions we're going to 00:07:08.15000:07:08.160 force it back through the heater hose 00:07:09.23000:07:09.240 all types of different areas trying to 00:07:11.21000:07:11.220 get all this out that we can 00:07:17.04900:07:17.059 first ones easy I drained it I still 00:07:20.64900:07:20.659 have the drain out that way I have the 00:07:22.71900:07:22.729 fastest flow possible just have the 00:07:26.22900:07:26.239 heater hose off running it till it's 00:07:28.80900:07:28.819 clear you can see like what we had to 00:07:30.81900:07:30.829 deal with as far as what's inside of 00:07:33.10000:07:33.110 this system that's going to be lined all 00:07:35.43900:07:35.449 over inside the block heater core 00:07:37.02900:07:37.039 radiator everywhere so this is going to 00:07:39.93900:07:39.949 take three or four flushes and you can 00:07:42.60900:07:42.619 expect to I've spent half a day on 00:07:44.55900:07:44.569 flushing an engine out before trying to 00:07:46.83900:07:46.849 get it clean also if you're going to 00:07:49.17900:07:49.189 replace your coolant bottle your D gas 00:07:50.88900:07:50.899 bottle do it last after your third or 00:07:53.58900:07:53.599 fourth flush that way you don't damage 00:07:56.16900:07:56.179 your brand-new bottle with the oil in it 00:07:58.17900:07:58.189 so just keep the dirty one on there for 00:08:00.51900:08:00.529 right now it's starting to come out 00:08:03.85000:08:03.860 pretty clean so I'm going to start it 00:08:05.31900:08:05.329 also when I start it the felts going to 00:08:07.60000:08:07.610 sling it all over the fenders but it is 00:08:10.47900:08:10.489 a messy job we know I don't know of any 00:08:12.75900:08:12.769 other way to get it clean so I'm going 00:08:15.42900:08:15.439 to go ahead and start it up and then let 00:08:17.25900:08:17.269 it run until it comes out clean that way 00:08:19.35900:08:19.369 too with it running now with there 00:08:24.45900:08:24.469 running we actually have it coming out 00:08:26.40900:08:26.419 the heater hose the water pumps forcing 00:08:28.92900:08:28.939 in assisting us 00:08:31.36000:08:31.370 his receipt ooh it's sprained everywhere 00:08:33.48000:08:33.490 that's why we want to do it both engine 00:08:35.92000:08:35.930 off engine running I'm going to do this 00:08:38.14000:08:38.150 multiple times cut it comes clean push 00:08:43.30000:08:43.310 water back through it the water pump 00:08:44.98000:08:44.990 this way till it comes out clear using 00:08:47.82900:08:47.839 the hose flush it this way that way it's 00:08:54.61000:08:54.620 pushed back up through the heater core 00:08:56.23000:08:56.240 until it comes out clean just a cheap 00:08:59.14000:08:59.150 little hose adapter and there's just a 00:09:01.90000:09:01.910 5/8 extension right there for the 00:09:04.99000:09:05.000 sprinklers the $2 item from Home Depot 00:09:07.84000:09:07.850 or Lowe's ace wherever you want to buy 00:09:10.60000:09:10.610 sprinkler parts at flushing it out this 00:09:13.57000:09:13.580 way till it's clean again with the added 00:09:16.78000:09:16.790 heat of control valve make sure it's 00:09:18.16000:09:18.170 turned on otherwise you have blockage 00:09:21.39000:09:21.400 then I'll add some more soap and do this 00:09:24.79000:09:24.800 again until I after a row test it 00:09:27.64000:09:27.650 doesn't come back to having a layer on 00:09:29.20000:09:29.210 top of it 00:09:29.95000:09:29.960 pull it second flush 00:10:29.87000:10:29.880 this is after the third flush I've got 00:10:33.84000:10:33.850 straight water in it right now looks 00:10:38.67000:10:38.680 pretty good 00:10:39.57000:10:39.580 nothing rising to the top doesn't look 00:10:41.40000:10:41.410 that bad a few pointers I like to just 00:10:44.16000:10:44.170 give out here to help you out expect 00:10:46.68000:10:46.690 anywhere from a minimum of three flushes 00:10:49.89000:10:49.900 I would think at least three and it 00:10:52.14000:10:52.150 takes time you're not just going to be 00:10:54.18000:10:54.190 able to add soap drive around the block 00:10:55.59000:10:55.600 stick a hose in it be done so you know 00:10:58.32000:10:58.330 expected spend half a day or so flushing 00:11:00.90000:11:00.910 this thing out 00:11:01.68000:11:01.690 Ford países anywhere from four to nine 00:11:04.20000:11:04.210 hours depending on the severity of it 00:11:06.39000:11:06.400 and the which engine it is so expect 00:11:09.48000:11:09.490 quite a bit if it's real bad like peanut 00:11:11.88000:11:11.890 butter in there expect to pull the plugs 00:11:14.19000:11:14.200 at the block and flush it out that way 00:11:16.35000:11:16.360 and do quite a bit pull the thermostat 00:11:18.36000:11:18.370 out try to do everything to get it to 00:11:20.10000:11:20.110 circulate you may have water pump issues 00:11:22.32000:11:22.330 if it's real bad but when it's just 00:11:24.24000:11:24.250 diesel fuel or a little bit of oil or 00:11:27.24000:11:27.250 some oil you know three four flushes 00:11:29.31000:11:29.320 should do it also depending on the type 00:11:31.47000:11:31.480 of soap that you use if it's real bad 00:11:34.47000:11:34.480 you may want to add simple green with 00:11:36.12000:11:36.130 the dish soap the dish powdered low 00:11:38.76000:11:38.770 sudsing stuff to help you out there with 00:11:41.01000:11:41.020 it and also with the straight water and 00:11:43.38000:11:43.390 leaving the old coolant bottle in it 00:11:44.88000:11:44.890 that way if I would have had a new 00:11:46.29000:11:46.300 coolant bottle in it 00:11:47.43000:11:47.440 it would have just stained it and I 00:11:49.08000:11:49.090 would have a new one that's all ruined 00:11:51.51000:11:51.520 and not look presentable to the customer 00:11:53.49000:11:53.500 or to yourself afterwards so straight 00:11:55.74000:11:55.750 water it's
