and 00:00:20.57000:00:20.580 head over to 1a auto comm with the trunk 00:00:23.66000:00:23.670 open over on the right side or the 00:00:26.15000:00:26.160 passenger side there should be a cover 00:00:28.16000:00:28.170 that goes right here this vehicle 00:00:30.34900:00:30.359 doesn't have one but you're gonna want 00:00:32.06000:00:32.070 to remove that cover battery is located 00:00:34.85000:00:34.860 right here first thing I'm gonna do is 00:00:36.97900:00:36.989 take a ten millimeter socket and a 00:00:39.26000:00:39.270 ratchet loosen up this nut for the 00:00:43.04000:00:43.050 negative terminal and it's loose slide 00:00:47.93000:00:47.940 off the cable slide it out of the way I 00:00:51.04000:00:51.050 want to take these push pins out right 00:00:53.42000:00:53.430 here I'm just going to use some side 00:00:55.06900:00:55.079 cutters get this Center pin pull that up 00:00:59.20900:00:59.219 and then slide it out 00:01:08.16900:01:08.179 be careful not to cut it get those up 00:01:12.31000:01:12.320 just grab this piece slide it out I'm 00:01:15.88000:01:15.890 gonna disconnect this connector right 00:01:17.46900:01:17.479 here just push down on that slide that 00:01:20.74000:01:20.750 out there's another connector right here 00:01:24.69000:01:24.700 I'm gonna slide the wiring out first 00:01:27.91000:01:27.920 just like that and the connector will 00:01:30.39900:01:30.409 come out slide that to the side like 00:01:37.80900:01:37.819 that I'm gonna take a t25 and a ratchet 00:01:42.19000:01:42.200 take this screw out right here I'm just 00:01:51.03900:01:51.049 gonna use this trim tool from wani otter 00:01:52.92900:01:52.939 calm take this push clip out pull it out 00:02:01.44000:02:01.450 all right now that is loose but what we 00:02:05.02000:02:05.030 need to do is we need to take the fan 00:02:06.72900:02:06.739 off because the fan has to come out with 00:02:09.94000:02:09.950 the shroud as one what we need to do to 00:02:13.09000:02:13.100 take the fan off is we need to 00:02:14.97900:02:14.989 disconnect the fan clutch from the 00:02:17.19900:02:17.209 engine side this is attached to one of 00:02:19.66000:02:19.670 the pulleys right there so sometimes 00:02:21.91000:02:21.920 these are somewhat difficult to get off 00:02:23.71000:02:23.720 so what we're going to do is use this 00:02:25.66000:02:25.670 tool we actually sell this at 1a auto 00:02:28.08900:02:28.099 comm with many different sizes this 00:02:30.91000:02:30.920 happens to be 32 millimeter that's gonna 00:02:34.69000:02:34.700 slide on there and then we slide this on 00:02:38.37900:02:38.389 and with a pneumatic air hammer we're 00:02:42.09900:02:42.109 gonna give it a couple bumps and it's 00:02:45.15900:02:45.169 gonna loosen up that nut and we should 00:02:46.96000:02:46.970 be able to get it off all right so now 00:02:49.56900:02:49.579 I'm gonna take the tool now this fan 00:02:52.08900:02:52.099 clutch happens to be on there 00:02:53.68000:02:53.690 reverse-thread so it's gonna seem like 00:02:56.55900:02:56.569 you're tightening it but you're actually 00:02:57.94000:02:57.950 loosening it so we'll go like that put 00:03:04.05900:03:04.069 our air hammer in there make sure you 00:03:05.83000:03:05.840 wear hearing protection and eye 00:03:07.78000:03:07.790 protection all right so that's loose 00:03:18.75000:03:18.760 took a little bit of effort but I got it 00:03:23.11000:03:23.120 now you can slide the tool off just move 00:03:31.42000:03:31.430 it a little bit you should be able to 00:03:39.69900:03:39.709 just spin it off like that 00:03:42.20900:03:42.219 you might need to the tool once in a 00:03:44.70900:03:44.719 while or good you use a you could use a 00:03:47.47000:03:47.480 wrench that fits 32 millimeter wrench 00:03:52.19900:03:52.209 all right I'm just gonna keep loosening 00:03:54.81900:03:54.829 this up be careful you don't want the 00:03:56.97900:03:56.989 fan to fall you don't want it to smash 00:03:59.44000:03:59.450 into the radiator especially if you're 00:04:01.50900:04:01.519 gonna reuse as a radiator fuel placing 00:04:04.00000:04:04.010 it it's not a big deal 00:04:06.83900:04:06.849 so I think as I get closer to the end 00:04:09.69000:04:09.700 I'll just move the pin and just grab the 00:04:13.59900:04:13.609 blade and there we go I can slide this 00:04:19.69000:04:19.700 right up just like that just gonna 00:04:24.01000:04:24.020 disconnect this connector to the mass 00:04:26.32000:04:26.330 airflow sensor 00:04:27.39900:04:27.409 push down on this tab wiggle it out take 00:04:32.29000:04:32.300 a straight blade screwdriver and sum up 00:04:34.12000:04:34.130 this clamp right here 00:04:38.62000:04:38.630 should be good push that snorkel off 00:04:44.02000:04:44.030 yeah and there's all these clips holding 00:04:49.13000:04:49.140 the top of the air box off I'm just 00:04:50.93000:04:50.940 gonna take the top off and this last one 00:04:54.29000:04:54.300 over here 00:04:55.04000:04:55.050 it's kind of tricky to get to dip stick 00:04:58.61000:04:58.620 out of the way just grab the air box 00:05:08.47000:05:08.480 filter out I'm gonna take these two 00:05:12.08000:05:12.090 bolts out and use a ten millimeter 00:05:13.64000:05:13.650 socket extension in an electric ratchet 00:05:16.40000:05:16.410 you can use a regular ratchet if you 00:05:18.02000:05:18.030 don't have an electric one or an 00:05:20.33000:05:20.340 air-powered one take them out 00:05:29.99000:05:30.000 just grab the airbox let's line it up 00:05:33.80000:05:33.810 this wire is on it this little grommet 00:05:38.43000:05:38.440 right here just try to slide that out 00:05:40.59000:05:40.600 just try to slide this off hey take that 00:05:50.55000:05:50.560 off just slide this out of the way I'm 00:05:54.18000:05:54.190 gonna pull this fill cap off before we 00:05:56.07000:05:56.080 drain the coolant make sure the engine 00:05:58.20000:05:58.210 is cold you don't want to take this off 00:06:00.06000:06:00.070 while the engines hot or you're gonna 00:06:01.95000:06:01.960 get splashed in the face with coolant 00:06:04.40000:06:04.410 pull that off and now we can raise the 00:06:08.43000:06:08.440 vehicle and drain the cooler underneath 00:06:10.65000:06:10.660 the vehicle there may be a cover right 00:06:12.81000:06:12.820 here you're gonna have to remove it 00:06:14.31000:06:14.320 there should be some fasteners there 00:06:16.05000:06:16.060 there and there 00:06:16.92000:06:16.930 yeah and then also back there this 00:06:21.27000:06:21.280 vehicle doesn't have it so we're just 00:06:23.55000:06:23.560 gonna start right here I need to loosen 00:06:25.98000:06:25.990 up this drain right here the this 00:06:29.61000:06:29.620 radiator is not the original radiator so 00:06:32.91000:06:32.920 I believe you're gonna have a different 00:06:34.50000:06:34.510 size socket to use if you have the OEM 00:06:38.13000:06:38.140 radiator for this one it's a 22 00:06:40.86000:06:40.870 millimeter socket I'm gonna use an 00:06:42.54000:06:42.550 extension and a ratchet listen to this 00:06:44.91000:06:44.920 up make sure you put a drain bucket 00:06:47.04000:06:47.050 underneath just gonna remove this 00:06:58.54000:06:58.550 there you go the neck that : looks nasty 00:07:04.99000:07:05.000 to help the coolant green out a little 00:07:07.30900:07:07.319 faster I'm gonna open this bleeder screw 00:07:09.14000:07:09.150 right here just use a straight blade 00:07:12.05000:07:12.060 screwdriver loosen this up alright I'm 00:07:15.74000:07:15.750 gonna test this coolant let's see how it 00:07:17.57000:07:17.580 how it does what we do is suck up some 00:07:21.43900:07:21.449 of this coolant it's gonna test the 00:07:26.83900:07:26.849 level of protection you have so with the 00:07:29.99000:07:30.000 tool level this is actually way out of 00:07:32.65900:07:32.669 spec it should be right there around 00:07:34.33900:07:34.349 negative 35 degrees Fahrenheit negative 00:07:38.48000:07:38.490 32 is ideal but um so this is way out of 00:07:42.26000:07:42.270 spec so it's a good thing we're gonna 00:07:43.64000:07:43.650 drain and fill this cool now we want to 00:07:46.52000:07:46.530 remove this side from the radiator I'm 00:07:48.52900:07:48.539 just gonna take a straight blade 00:07:49.77900:07:49.789 screwdriver slide up under this 00:07:52.27900:07:52.289 retaining clip right there and then 00:07:54.71000:07:54.720 there's also one right here just like 00:07:59.12000:07:59.130 that 00:08:02.98000:08:02.990 I can just grab this hose and just 00:08:05.35000:08:05.360 wiggle it a little bit all right have 00:08:15.43000:08:15.440 that off it's good 00:08:18.61000:08:18.620 don't take the screwdriver just take 00:08:21.24900:08:21.259 this hose off completely slide the clip 00:08:26.29000:08:26.300 out just google this back and forth oh 00:08:29.49900:08:29.509 no there's a screw right here I'm gonna 00:08:32.68000:08:32.690 use a t20 socket extension and a ratchet 00:08:36.33900:08:36.349 take that screw out now I can move the 00:08:41.44000:08:41.450 radiator out a little bit and we're 00:08:43.83900:08:43.849 gonna take this screw up now if you 00:08:45.73000:08:45.740 weren't taking this section of the 00:08:47.65000:08:47.660 radiator off and you were just doing the 00:08:49.87000:08:49.880 reservoir you can loosen up the bolts on 00:08:52.30000:08:52.310 the headlight move the headlight forward 00:08:54.54000:08:54.550 then you might be able to gain access to 00:08:57.13000:08:57.140 that screw right there we're going to 00:09:02.56000:09:02.570 use a t20 on this screw take this one up 00:09:11.36000:09:11.370 pull screw up so I want to pull this : 00:09:14.21000:09:14.220 toes off just use a straight blade 00:09:16.16000:09:16.170 screwdriver or a pick just pull up on 00:09:20.24000:09:20.250 the retainer clip and just wiggle it off 00:09:26.23000:09:26.240 you go like that out a lot more : came 00:09:32.30000:09:32.310 out make sure you still have your drain 00:09:35.93000:09:35.940 bucket underneath there now from 00:09:39.02000:09:39.030 underneath the vehicle you don't 00:09:40.07000:09:40.080 necessarily have to be from underneath 00:09:41.84000:09:41.850 the vehicle I just wanted to show you 00:09:43.31000:09:43.320 how this worked there's a little lever 00:09:45.56000:09:45.570 right here that you can actually grab 00:09:47.60000:09:47.610 from above the vehicle and you just pull 00:09:50.57000:09:50.580 it towards the center of the vehicle 00:09:52.67000:09:52.680 just like that and that releases the 00:09:55.13000:09:55.140 lock that holds that in so now that clip 00:09:58.70000:09:58.710 is released now we're just gonna grab 00:10:00.29000:10:00.300 the tank and slide it up the coolant 00:10:02.93000:10:02.940 sensor is still down there we'll have to 00:10:05.60000:10:05.610 disconnect that but I'm just gonna grab 00:10:08.21000:10:08.220 the tank and just pry it straight up be 00:10:11.09000:10:11.100 careful you don't want to rock it back 00:10:13.04000:10:13.050 and forth too much because you could 00:10:14.66000:10:14.670 break other plastic just pull it up just 00:10:19.16000:10:19.170 like that you're gonna have some more 00:10:20.69000:10:20.700 coolant come out slide it up you slide 00:10:26.15000:10:26.160 it up I can disconnect the connector 00:10:27.77000:10:27.780 right here push down with the tab pull 00:10:35.33000:10:35.340 it on like that 00:10:36.67000:10:36.680 alright now this one happens to be 00:10:39.71000:10:39.720 broken so I'm just gonna pull this 00:10:42.20000:10:42.210 broken piece up and then I can use a pic 00:10:44.42000:10:44.430 just try to get in here and grab this 00:10:47.86000:10:47.870 somehow 00:10:48.93000:10:48.94000:10:53.78000:10:53.790 just slide that up otherwise normally 00:10:57.45000:10:57.460 you would just be able to grab the top 00:10:59.10000:10:59.110 part and just pull up on it if you have 00:11:01.80000:11:01.810 to use a pick just be careful not to 00:11:04.29000:11:04.300 damage any of the plastic on the side 00:11:06.99000:11:07.000 there here's the old part here's the new 00:11:09.93000:11:09.940 oil cooler thermostat from 1a auto comm 00:11:13.29000:11:13.300 the shape is the same the top part is 00:11:17.01000:11:17.020 the same even though the old one is 00:11:18.45000:11:18.460 broken has the same internals get shares 00:11:22.95000:11:22.960 at 1a auto comm and you'll be ready to 00:11:25.11000:11:25.120 rock and roll 00:11:26.47000:11:26.48000:11:40.43000:11:40.440 now there is a key way on this 00:11:43.19900:11:43.209 thermostat you're just gonna slide this 00:11:45.60000:11:45.610 in back here it's gonna be on the back 00:11:48.26900:11:48.279 side there push it all the way down now 00:11:52.37900:11:52.389 I'll take the reservoir snap the lock 00:11:55.23000:11:55.240 back down and then I'll just connect the 00:11:59.00900:11:59.019 coolant level sensor right here before I 00:12:03.48000:12:03.490 slide this in lock that in place and 00:12:08.99000:12:09.000 then slide the reservoir on and then 00:12:16.88900:12:16.899 make sure this tab is lined up right 00:12:18.62900:12:18.639 here I'm just gonna hold underneath this 00:12:23.73000:12:23.740 panel as I push down pin and lock it in 00:12:28.28000:12:28.290 take this hose line this up and lock it 00:12:33.26900:12:33.279 in place just like that take this screw 00:12:37.23000:12:37.240 right here it's just easier to put this 00:12:40.92000:12:40.930 on before I put the hose on get that 00:12:44.63900:12:44.649 started you take a t25 tension and a 00:12:53.49000:12:53.500 socket tighten this down just snug it is 00:12:57.12000:12:57.130 in plastic so be careful all right take 00:13:01.50000:13:01.510 this pipe this upper hose just line that 00:13:04.50000:13:04.510 up right there lock it in place and then 00:13:08.61000:13:08.620 over here line this up over here and 00:13:14.31000:13:14.320 just wiggle it a little bit lock that in 00:13:18.09000:13:18.100 place make sure this reservoir is locked 00:13:20.43000:13:20.440 in - that's good so these have to go on 00:13:24.66000:13:24.670 together just slide this in position 00:13:37.63900:13:37.649 once you get this close I'm gonna start 00:13:41.97000:13:41.980 to tighten up the fan now these and 00:13:44.97000:13:44.980 blades are the fan clutch is 00:13:47.46000:13:47.470 reverse-thread 00:13:48.68000:13:48.690 so it's almost like you're gonna be 00:13:51.12000:13:51.130 loosening it it's really no easy way to 00:13:58.47000:13:58.480 do this just do it carefully you get it 00:14:04.05000:14:04.060 started it's a little bit easier make 00:14:08.12900:14:08.139 sure that fan shroud is in properly 00:14:16.12900:14:16.139 that's good alright if you have the 00:14:19.07900:14:19.089 ability to torque this nut for the fan 00:14:22.87900:14:22.889 you're gonna torque that between 22 and 00:14:26.55000:14:26.560 29 foot-pounds I don't really have that 00:14:29.87900:14:29.889 ability so I'm just gonna put this tool 00:14:31.76900:14:31.779 on there and just give it a little tap 00:14:34.81900:14:34.829 that should be good right here there's a 00:14:38.28000:14:38.290 push pin it's gonna go back in here 00:14:40.85000:14:40.860 slide that in position and lock it down 00:14:50.60000:14:50.610 on this side we're gonna put this screw 00:14:54.25900:14:54.269 right here then I'm gonna use a t25 and 00:14:59.06000:14:59.070 the electric ratchet tighten this down 00:15:06.00900:15:06.019 just snug 00:15:07.57900:15:07.589 I'll put position this wiring harness 00:15:09.41000:15:09.420 right here and we'll plug the connector 00:15:13.28000:15:13.290 in right here lock that in place now 00:15:23.36000:15:23.370 we're just going to slide this side of 00:15:24.94900:15:24.959 the lower air box in here yours may have 00:15:27.98000:15:27.990 something that this connects to this 00:15:30.53000:15:30.540 vehicle doesn't it just slides in 00:15:34.10000:15:34.110 position and in this lower part slides 00:15:38.63000:15:38.640 there and make sure these holes are 00:15:40.67000:15:40.680 lined up take these two bolts get 00:15:46.10000:15:46.110 started take a ten millimeter socket and 00:15:51.23000:15:51.240 a ratchet and tighten these down I'm 00:15:52.94000:15:52.950 using an electric rattle you don't have 00:15:55.67000:15:55.680 an electric graduate just use a manual 00:15:58.13000:15:58.140 one the air filter you install it don't 00:16:03.86000:16:03.870 take the top part of the air box I'm 00:16:07.04000:16:07.050 gonna slide it onto the snorkel first 00:16:18.06900:16:18.079 and then there's all these clips these 00:16:24.29000:16:24.300 clips 00:16:26.30900:16:26.319 lock this part down connect the mass 00:16:32.71000:16:32.720 airflow sensor or air flow meter and 00:16:38.22900:16:38.239 we're gonna slide this clamp right here 00:16:41.33900:16:41.349 take a straight blade screwdriver and 00:16:43.92900:16:43.939 tighten it down 00:16:48.17900:16:48.189 just snug not too tight give it a shake 00:16:55.21000:16:55.220 make sure it's good take this piece 00:16:57.74900:16:57.759 slide this into the air box just like 00:17:02.82900:17:02.83900:17:03.41900:17:03.429 and there's retainers right here take 00:17:07.17900:17:07.189 those pushpins lock them down 00:17:19.61000:17:19.620 and we can take the negative side 00:17:21.35000:17:21.360 connect the negative side take the same 00:17:25.24900:17:25.259 10 millimeter socket and ratchet tighten 00:17:28.58000:17:28.590 it up that's good at this point if you 00:17:35.48000:17:35.490 had that cover you're gonna want to put 00:17:37.03900:17:37.049 the cover back where it goes when adding 00:17:39.68000:17:39.690 the coolant we're gonna use a funnel and 00:17:41.45000:17:41.460 you want to make sure you add the 00:17:43.19000:17:43.200 appropriate type of coolant you can 00:17:44.93000:17:44.940 check your owner's manual there is BMW 00:17:47.77900:17:47.789 specific coolant generally it's blue 00:17:50.53900:17:50.549 coolant so we're gonna add we're gonna 00:17:53.23900:17:53.249 fill up the reservoir we're gonna take 00:17:58.58000:17:58.590 this bleeder screw out just use a 00:18:01.48900:18:01.499 straight blade screwdriver or a Philips 00:18:03.83000:18:03.840 head just move that funnel you could 00:18:09.23000:18:09.240 probably just loosen this up a little 00:18:11.09000:18:11.100 bit or you can take it all the way out 00:18:13.53900:18:13.549 just like that set it aside you want to 00:18:16.85000:18:16.860 fill this all the way up to the top and 00:18:18.61900:18:18.629 have coolant come bubbling out of the 00:18:21.16900:18:21.179 bleeder hole once it's coming out of 00:18:23.65900:18:23.669 there we're gonna reinstall the bleeder 00:18:26.77900:18:26.789 screw it's it is plastic so be careful 00:18:30.47000:18:30.480 you don't want to strip this it just 00:18:33.91900:18:33.929 start it again then close that bleeder 00:18:38.69000:18:38.700 screw and then you're gonna adjust the 00:18:41.33000:18:41.340 level in here now there is a little 00:18:43.54900:18:43.559 dipstick and here when this is full this 00:18:48.71000:18:48.720 is gonna be all the way at the top now 00:18:50.72000:18:50.730 you can check it right here it shows 00:18:52.36900:18:52.379 where the min and the max is so you want 00:18:55.48900:18:55.499 to adjust that accordingly you can add 00:18:57.71000:18:57.720 coolant or take out coolant you can use 00:19:00.64900:19:00.659 like a turkey baster or some type of 00:19:03.63900:19:03.649 fluid pump to suck the fluid out then 00:19:07.36900:19:07.379 you want to let it run you want to leave 00:19:08.96000:19:08.970 the heat on when you leave the heat on 00:19:11.74900:19:11.759 if you don't have heat you're gonna want 00:19:14.26900:19:14.279 to crack this open a little bit and just 00:19:16.99900:19:17.009 make sure you get some of the coolant 00:19:18.83000:19:18.840 out it's probably a good idea to shut 00:19:20.53900:19:20.549 the engine off let it cool down and 00:19:22.15900:19:22.169 readjust your colon when you're done 00:19:25.00900:19:25.019 when the fluid levels at the appropriate 00:19:27.37900:19:27.389 level take the cap 00:19:29.46000:19:29.470 put it back on make sure you monitor 00:19:32.36900:19:32.379 your temp gauge while you're running the 00:19:34.32000:19:34.330 vehicle if you run the vehicle for about 00:19:36.53900:19:36.549 10 minutes the temp gauge should go 00:19:39.50900:19:39.519 right in the middle there if it starts 00:19:41.24900:19:41.259 going to the red shut the vehicle off 00:19:43.28900:19:43.299 and start over 00:19:44.46000:19:44.470 leave the system again thanks for 00:19:46.52900:19:46.539 watching visit 1a auto comm for quality 00:19:48.86900:19:48.879 auto parts shipped to your door the
