00:00:10.100 00:00:10.110 replace the oil cooler thermostat on
00:00:12.470 00:00:12.480 this 2001 BMW 325 X I if you need this
00:00:17.150 00:00:17.160 part or other parts for your vehicle
00:00:18.980 00:00:18.990 click the link in the description and
00:00:20.570 00:00:20.580 head over to 1a auto comm with the trunk
00:00:23.660 00:00:23.670 open over on the right side or the
00:00:26.150 00:00:26.160 passenger side there should be a cover
00:00:28.160 00:00:28.170 that goes right here this vehicle
00:00:30.349 00:00:30.359 doesn't have one but you're gonna want
00:00:32.060 00:00:32.070 to remove that cover battery is located
00:00:34.850 00:00:34.860 right here first thing I'm gonna do is
00:00:36.979 00:00:36.989 take a ten millimeter socket and a
00:00:39.260 00:00:39.270 ratchet loosen up this nut for the
00:00:43.040 00:00:43.050 negative terminal and it's loose slide
00:00:47.930 00:00:47.940 off the cable slide it out of the way I
00:00:51.040 00:00:51.050 want to take these push pins out right
00:00:53.420 00:00:53.430 here I'm just going to use some side
00:00:55.069 00:00:55.079 cutters get this Center pin pull that up
00:00:59.209 00:00:59.219 and then slide it out
00:01:08.169 00:01:08.179 be careful not to cut it get those up
00:01:12.310 00:01:12.320 just grab this piece slide it out I'm
00:01:15.880 00:01:15.890 gonna disconnect this connector right
00:01:17.469 00:01:17.479 here just push down on that slide that
00:01:20.740 00:01:20.750 out there's another connector right here
00:01:24.690 00:01:24.700 I'm gonna slide the wiring out first
00:01:27.910 00:01:27.920 just like that and the connector will
00:01:30.399 00:01:30.409 come out slide that to the side like
00:01:37.809 00:01:37.819 that I'm gonna take a t25 and a ratchet
00:01:42.190 00:01:42.200 take this screw out right here I'm just
00:01:51.039 00:01:51.049 gonna use this trim tool from wani otter
00:01:52.929 00:01:52.939 calm take this push clip out pull it out
00:02:01.440 00:02:01.450 all right now that is loose but what we
00:02:05.020 00:02:05.030 need to do is we need to take the fan
00:02:06.729 00:02:06.739 off because the fan has to come out with
00:02:09.940 00:02:09.950 the shroud as one what we need to do to
00:02:13.090 00:02:13.100 take the fan off is we need to
00:02:14.979 00:02:14.989 disconnect the fan clutch from the
00:02:17.199 00:02:17.209 engine side this is attached to one of
00:02:19.660 00:02:19.670 the pulleys right there so sometimes
00:02:21.910 00:02:21.920 these are somewhat difficult to get off
00:02:23.710 00:02:23.720 so what we're going to do is use this
00:02:25.660 00:02:25.670 tool we actually sell this at 1a auto
00:02:28.089 00:02:28.099 comm with many different sizes this
00:02:30.910 00:02:30.920 happens to be 32 millimeter that's gonna
00:02:34.690 00:02:34.700 slide on there and then we slide this on
00:02:38.379 00:02:38.389 and with a pneumatic air hammer we're
00:02:42.099 00:02:42.109 gonna give it a couple bumps and it's
00:02:45.159 00:02:45.169 gonna loosen up that nut and we should
00:02:46.960 00:02:46.970 be able to get it off all right so now
00:02:49.569 00:02:49.579 I'm gonna take the tool now this fan
00:02:52.089 00:02:52.099 clutch happens to be on there
00:02:53.680 00:02:53.690 reverse-thread so it's gonna seem like
00:02:56.559 00:02:56.569 you're tightening it but you're actually
00:02:57.940 00:02:57.950 loosening it so we'll go like that put
00:03:04.059 00:03:04.069 our air hammer in there make sure you
00:03:05.830 00:03:05.840 wear hearing protection and eye
00:03:07.780 00:03:07.790 protection all right so that's loose
00:03:18.750 00:03:18.760 took a little bit of effort but I got it
00:03:23.110 00:03:23.120 now you can slide the tool off just move
00:03:31.420 00:03:31.430 it a little bit you should be able to
00:03:39.699 00:03:39.709 just spin it off like that
00:03:42.209 00:03:42.219 you might need to the tool once in a
00:03:44.709 00:03:44.719 while or good you use a you could use a
00:03:47.470 00:03:47.480 wrench that fits 32 millimeter wrench
00:03:52.199 00:03:52.209 all right I'm just gonna keep loosening
00:03:54.819 00:03:54.829 this up be careful you don't want the
00:03:56.979 00:03:56.989 fan to fall you don't want it to smash
00:03:59.440 00:03:59.450 into the radiator especially if you're
00:04:01.509 00:04:01.519 gonna reuse as a radiator fuel placing
00:04:04.000 00:04:04.010 it it's not a big deal
00:04:06.839 00:04:06.849 so I think as I get closer to the end
00:04:09.690 00:04:09.700 I'll just move the pin and just grab the
00:04:13.599 00:04:13.609 blade and there we go I can slide this
00:04:19.690 00:04:19.700 right up just like that just gonna
00:04:24.010 00:04:24.020 disconnect this connector to the mass
00:04:26.320 00:04:26.330 airflow sensor
00:04:27.399 00:04:27.409 push down on this tab wiggle it out take
00:04:32.290 00:04:32.300 a straight blade screwdriver and sum up
00:04:34.120 00:04:34.130 this clamp right here
00:04:38.620 00:04:38.630 should be good push that snorkel off
00:04:44.020 00:04:44.030 yeah and there's all these clips holding
00:04:49.130 00:04:49.140 the top of the air box off I'm just
00:04:50.930 00:04:50.940 gonna take the top off and this last one
00:04:54.290 00:04:54.300 over here
00:04:55.040 00:04:55.050 it's kind of tricky to get to dip stick
00:04:58.610 00:04:58.620 out of the way just grab the air box
00:05:08.470 00:05:08.480 filter out I'm gonna take these two
00:05:12.080 00:05:12.090 bolts out and use a ten millimeter
00:05:13.640 00:05:13.650 socket extension in an electric ratchet
00:05:16.400 00:05:16.410 you can use a regular ratchet if you
00:05:18.020 00:05:18.030 don't have an electric one or an
00:05:20.330 00:05:20.340 air-powered one take them out
00:05:29.990 00:05:30.000 just grab the airbox let's line it up
00:05:33.800 00:05:33.810 this wire is on it this little grommet
00:05:38.430 00:05:38.440 right here just try to slide that out
00:05:40.590 00:05:40.600 just try to slide this off hey take that
00:05:50.550 00:05:50.560 off just slide this out of the way I'm
00:05:54.180 00:05:54.190 gonna pull this fill cap off before we
00:05:56.070 00:05:56.080 drain the coolant make sure the engine
00:05:58.200 00:05:58.210 is cold you don't want to take this off
00:06:00.060 00:06:00.070 while the engines hot or you're gonna
00:06:01.950 00:06:01.960 get splashed in the face with coolant
00:06:04.400 00:06:04.410 pull that off and now we can raise the
00:06:08.430 00:06:08.440 vehicle and drain the cooler underneath
00:06:10.650 00:06:10.660 the vehicle there may be a cover right
00:06:12.810 00:06:12.820 here you're gonna have to remove it
00:06:14.310 00:06:14.320 there should be some fasteners there
00:06:16.050 00:06:16.060 there and there
00:06:16.920 00:06:16.930 yeah and then also back there this
00:06:21.270 00:06:21.280 vehicle doesn't have it so we're just
00:06:23.550 00:06:23.560 gonna start right here I need to loosen
00:06:25.980 00:06:25.990 up this drain right here the this
00:06:29.610 00:06:29.620 radiator is not the original radiator so
00:06:32.910 00:06:32.920 I believe you're gonna have a different
00:06:34.500 00:06:34.510 size socket to use if you have the OEM
00:06:38.130 00:06:38.140 radiator for this one it's a 22
00:06:40.860 00:06:40.870 millimeter socket I'm gonna use an
00:06:42.540 00:06:42.550 extension and a ratchet listen to this
00:06:44.910 00:06:44.920 up make sure you put a drain bucket
00:06:47.040 00:06:47.050 underneath just gonna remove this
00:06:58.540 00:06:58.550 there you go the neck that : looks nasty
00:07:04.990 00:07:05.000 to help the coolant green out a little
00:07:07.309 00:07:07.319 faster I'm gonna open this bleeder screw
00:07:09.140 00:07:09.150 right here just use a straight blade
00:07:12.050 00:07:12.060 screwdriver loosen this up alright I'm
00:07:15.740 00:07:15.750 gonna test this coolant let's see how it
00:07:17.570 00:07:17.580 how it does what we do is suck up some
00:07:21.439 00:07:21.449 of this coolant it's gonna test the
00:07:26.839 00:07:26.849 level of protection you have so with the
00:07:29.990 00:07:30.000 tool level this is actually way out of
00:07:32.659 00:07:32.669 spec it should be right there around
00:07:34.339 00:07:34.349 negative 35 degrees Fahrenheit negative
00:07:38.480 00:07:38.490 32 is ideal but um so this is way out of
00:07:42.260 00:07:42.270 spec so it's a good thing we're gonna
00:07:43.640 00:07:43.650 drain and fill this cool now we want to
00:07:46.520 00:07:46.530 remove this side from the radiator I'm
00:07:48.529 00:07:48.539 just gonna take a straight blade
00:07:49.779 00:07:49.789 screwdriver slide up under this
00:07:52.279 00:07:52.289 retaining clip right there and then
00:07:54.710 00:07:54.720 there's also one right here just like
00:07:59.120 00:07:59.130 that
00:08:02.980 00:08:02.990 I can just grab this hose and just
00:08:05.350 00:08:05.360 wiggle it a little bit all right have
00:08:15.430 00:08:15.440 that off it's good
00:08:18.610 00:08:18.620 don't take the screwdriver just take
00:08:21.249 00:08:21.259 this hose off completely slide the clip
00:08:26.290 00:08:26.300 out just google this back and forth oh
00:08:29.499 00:08:29.509 no there's a screw right here I'm gonna
00:08:32.680 00:08:32.690 use a t20 socket extension and a ratchet
00:08:36.339 00:08:36.349 take that screw out now I can move the
00:08:41.440 00:08:41.450 radiator out a little bit and we're
00:08:43.839 00:08:43.849 gonna take this screw up now if you
00:08:45.730 00:08:45.740 weren't taking this section of the
00:08:47.650 00:08:47.660 radiator off and you were just doing the
00:08:49.870 00:08:49.880 reservoir you can loosen up the bolts on
00:08:52.300 00:08:52.310 the headlight move the headlight forward
00:08:54.540 00:08:54.550 then you might be able to gain access to
00:08:57.130 00:08:57.140 that screw right there we're going to
00:09:02.560 00:09:02.570 use a t20 on this screw take this one up
00:09:11.360 00:09:11.370 pull screw up so I want to pull this :
00:09:14.210 00:09:14.220 toes off just use a straight blade
00:09:16.160 00:09:16.170 screwdriver or a pick just pull up on
00:09:20.240 00:09:20.250 the retainer clip and just wiggle it off
00:09:26.230 00:09:26.240 you go like that out a lot more : came
00:09:32.300 00:09:32.310 out make sure you still have your drain
00:09:35.930 00:09:35.940 bucket underneath there now from
00:09:39.020 00:09:39.030 underneath the vehicle you don't
00:09:40.070 00:09:40.080 necessarily have to be from underneath
00:09:41.840 00:09:41.850 the vehicle I just wanted to show you
00:09:43.310 00:09:43.320 how this worked there's a little lever
00:09:45.560 00:09:45.570 right here that you can actually grab
00:09:47.600 00:09:47.610 from above the vehicle and you just pull
00:09:50.570 00:09:50.580 it towards the center of the vehicle
00:09:52.670 00:09:52.680 just like that and that releases the
00:09:55.130 00:09:55.140 lock that holds that in so now that clip
00:09:58.700 00:09:58.710 is released now we're just gonna grab
00:10:00.290 00:10:00.300 the tank and slide it up the coolant
00:10:02.930 00:10:02.940 sensor is still down there we'll have to
00:10:05.600 00:10:05.610 disconnect that but I'm just gonna grab
00:10:08.210 00:10:08.220 the tank and just pry it straight up be
00:10:11.090 00:10:11.100 careful you don't want to rock it back
00:10:13.040 00:10:13.050 and forth too much because you could
00:10:14.660 00:10:14.670 break other plastic just pull it up just
00:10:19.160 00:10:19.170 like that you're gonna have some more
00:10:20.690 00:10:20.700 coolant come out slide it up you slide
00:10:26.150 00:10:26.160 it up I can disconnect the connector
00:10:27.770 00:10:27.780 right here push down with the tab pull
00:10:35.330 00:10:35.340 it on like that
00:10:36.670 00:10:36.680 alright now this one happens to be
00:10:39.710 00:10:39.720 broken so I'm just gonna pull this
00:10:42.200 00:10:42.210 broken piece up and then I can use a pic
00:10:44.420 00:10:44.430 just try to get in here and grab this
00:10:47.860 00:10:47.870 somehow
00:10:48.930 00:10:48.940 00:10:53.780 00:10:53.790 just slide that up otherwise normally
00:10:57.450 00:10:57.460 you would just be able to grab the top
00:10:59.100 00:10:59.110 part and just pull up on it if you have
00:11:01.800 00:11:01.810 to use a pick just be careful not to
00:11:04.290 00:11:04.300 damage any of the plastic on the side
00:11:06.990 00:11:07.000 there here's the old part here's the new
00:11:09.930 00:11:09.940 oil cooler thermostat from 1a auto comm
00:11:13.290 00:11:13.300 the shape is the same the top part is
00:11:17.010 00:11:17.020 the same even though the old one is
00:11:18.450 00:11:18.460 broken has the same internals get shares
00:11:22.950 00:11:22.960 at 1a auto comm and you'll be ready to
00:11:25.110 00:11:25.120 rock and roll
00:11:26.470 00:11:26.480 00:11:40.430 00:11:40.440 now there is a key way on this
00:11:43.199 00:11:43.209 thermostat you're just gonna slide this
00:11:45.600 00:11:45.610 in back here it's gonna be on the back
00:11:48.269 00:11:48.279 side there push it all the way down now
00:11:52.379 00:11:52.389 I'll take the reservoir snap the lock
00:11:55.230 00:11:55.240 back down and then I'll just connect the
00:11:59.009 00:11:59.019 coolant level sensor right here before I
00:12:03.480 00:12:03.490 slide this in lock that in place and
00:12:08.990 00:12:09.000 then slide the reservoir on and then
00:12:16.889 00:12:16.899 make sure this tab is lined up right
00:12:18.629 00:12:18.639 here I'm just gonna hold underneath this
00:12:23.730 00:12:23.740 panel as I push down pin and lock it in
00:12:28.280 00:12:28.290 take this hose line this up and lock it
00:12:33.269 00:12:33.279 in place just like that take this screw
00:12:37.230 00:12:37.240 right here it's just easier to put this
00:12:40.920 00:12:40.930 on before I put the hose on get that
00:12:44.639 00:12:44.649 started you take a t25 tension and a
00:12:53.490 00:12:53.500 socket tighten this down just snug it is
00:12:57.120 00:12:57.130 in plastic so be careful all right take
00:13:01.500 00:13:01.510 this pipe this upper hose just line that
00:13:04.500 00:13:04.510 up right there lock it in place and then
00:13:08.610 00:13:08.620 over here line this up over here and
00:13:14.310 00:13:14.320 just wiggle it a little bit lock that in
00:13:18.090 00:13:18.100 place make sure this reservoir is locked
00:13:20.430 00:13:20.440 in - that's good so these have to go on
00:13:24.660 00:13:24.670 together just slide this in position
00:13:37.639 00:13:37.649 once you get this close I'm gonna start
00:13:41.970 00:13:41.980 to tighten up the fan now these and
00:13:44.970 00:13:44.980 blades are the fan clutch is
00:13:47.460 00:13:47.470 reverse-thread
00:13:48.680 00:13:48.690 so it's almost like you're gonna be
00:13:51.120 00:13:51.130 loosening it it's really no easy way to
00:13:58.470 00:13:58.480 do this just do it carefully you get it
00:14:04.050 00:14:04.060 started it's a little bit easier make
00:14:08.129 00:14:08.139 sure that fan shroud is in properly
00:14:16.129 00:14:16.139 that's good alright if you have the
00:14:19.079 00:14:19.089 ability to torque this nut for the fan
00:14:22.879 00:14:22.889 you're gonna torque that between 22 and
00:14:26.550 00:14:26.560 29 foot-pounds I don't really have that
00:14:29.879 00:14:29.889 ability so I'm just gonna put this tool
00:14:31.769 00:14:31.779 on there and just give it a little tap
00:14:34.819 00:14:34.829 that should be good right here there's a
00:14:38.280 00:14:38.290 push pin it's gonna go back in here
00:14:40.850 00:14:40.860 slide that in position and lock it down
00:14:50.600 00:14:50.610 on this side we're gonna put this screw
00:14:54.259 00:14:54.269 right here then I'm gonna use a t25 and
00:14:59.060 00:14:59.070 the electric ratchet tighten this down
00:15:06.009 00:15:06.019 just snug
00:15:07.579 00:15:07.589 I'll put position this wiring harness
00:15:09.410 00:15:09.420 right here and we'll plug the connector
00:15:13.280 00:15:13.290 in right here lock that in place now
00:15:23.360 00:15:23.370 we're just going to slide this side of
00:15:24.949 00:15:24.959 the lower air box in here yours may have
00:15:27.980 00:15:27.990 something that this connects to this
00:15:30.530 00:15:30.540 vehicle doesn't it just slides in
00:15:34.100 00:15:34.110 position and in this lower part slides
00:15:38.630 00:15:38.640 there and make sure these holes are
00:15:40.670 00:15:40.680 lined up take these two bolts get
00:15:46.100 00:15:46.110 started take a ten millimeter socket and
00:15:51.230 00:15:51.240 a ratchet and tighten these down I'm
00:15:52.940 00:15:52.950 using an electric rattle you don't have
00:15:55.670 00:15:55.680 an electric graduate just use a manual
00:15:58.130 00:15:58.140 one the air filter you install it don't
00:16:03.860 00:16:03.870 take the top part of the air box I'm
00:16:07.040 00:16:07.050 gonna slide it onto the snorkel first
00:16:18.069 00:16:18.079 and then there's all these clips these
00:16:24.290 00:16:24.300 clips
00:16:26.309 00:16:26.319 lock this part down connect the mass
00:16:32.710 00:16:32.720 airflow sensor or air flow meter and
00:16:38.229 00:16:38.239 we're gonna slide this clamp right here
00:16:41.339 00:16:41.349 take a straight blade screwdriver and
00:16:43.929 00:16:43.939 tighten it down
00:16:48.179 00:16:48.189 just snug not too tight give it a shake
00:16:55.210 00:16:55.220 make sure it's good take this piece
00:16:57.749 00:16:57.759 slide this into the air box just like
00:17:02.829 00:17:02.839 00:17:03.419 00:17:03.429 and there's retainers right here take
00:17:07.179 00:17:07.189 those pushpins lock them down
00:17:19.610 00:17:19.620 and we can take the negative side
00:17:21.350 00:17:21.360 connect the negative side take the same
00:17:25.249 00:17:25.259 10 millimeter socket and ratchet tighten
00:17:28.580 00:17:28.590 it up that's good at this point if you
00:17:35.480 00:17:35.490 had that cover you're gonna want to put
00:17:37.039 00:17:37.049 the cover back where it goes when adding
00:17:39.680 00:17:39.690 the coolant we're gonna use a funnel and
00:17:41.450 00:17:41.460 you want to make sure you add the
00:17:43.190 00:17:43.200 appropriate type of coolant you can
00:17:44.930 00:17:44.940 check your owner's manual there is BMW
00:17:47.779 00:17:47.789 specific coolant generally it's blue
00:17:50.539 00:17:50.549 coolant so we're gonna add we're gonna
00:17:53.239 00:17:53.249 fill up the reservoir we're gonna take
00:17:58.580 00:17:58.590 this bleeder screw out just use a
00:18:01.489 00:18:01.499 straight blade screwdriver or a Philips
00:18:03.830 00:18:03.840 head just move that funnel you could
00:18:09.230 00:18:09.240 probably just loosen this up a little
00:18:11.090 00:18:11.100 bit or you can take it all the way out
00:18:13.539 00:18:13.549 just like that set it aside you want to
00:18:16.850 00:18:16.860 fill this all the way up to the top and
00:18:18.619 00:18:18.629 have coolant come bubbling out of the
00:18:21.169 00:18:21.179 bleeder hole once it's coming out of
00:18:23.659 00:18:23.669 there we're gonna reinstall the bleeder
00:18:26.779 00:18:26.789 screw it's it is plastic so be careful
00:18:30.470 00:18:30.480 you don't want to strip this it just
00:18:33.919 00:18:33.929 start it again then close that bleeder
00:18:38.690 00:18:38.700 screw and then you're gonna adjust the
00:18:41.330 00:18:41.340 level in here now there is a little
00:18:43.549 00:18:43.559 dipstick and here when this is full this
00:18:48.710 00:18:48.720 is gonna be all the way at the top now
00:18:50.720 00:18:50.730 you can check it right here it shows
00:18:52.369 00:18:52.379 where the min and the max is so you want
00:18:55.489 00:18:55.499 to adjust that accordingly you can add
00:18:57.710 00:18:57.720 coolant or take out coolant you can use
00:19:00.649 00:19:00.659 like a turkey baster or some type of
00:19:03.639 00:19:03.649 fluid pump to suck the fluid out then
00:19:07.369 00:19:07.379 you want to let it run you want to leave
00:19:08.960 00:19:08.970 the heat on when you leave the heat on
00:19:11.749 00:19:11.759 if you don't have heat you're gonna want
00:19:14.269 00:19:14.279 to crack this open a little bit and just
00:19:16.999 00:19:17.009 make sure you get some of the coolant
00:19:18.830 00:19:18.840 out it's probably a good idea to shut
00:19:20.539 00:19:20.549 the engine off let it cool down and
00:19:22.159 00:19:22.169 readjust your colon when you're done
00:19:25.009 00:19:25.019 when the fluid levels at the appropriate
00:19:27.379 00:19:27.389 level take the cap
00:19:29.460 00:19:29.470 put it back on make sure you monitor
00:19:32.369 00:19:32.379 your temp gauge while you're running the
00:19:34.320 00:19:34.330 vehicle if you run the vehicle for about
00:19:36.539 00:19:36.549 10 minutes the temp gauge should go
00:19:39.509 00:19:39.519 right in the middle there if it starts
00:19:41.249 00:19:41.259 going to the red shut the vehicle off
00:19:43.289 00:19:43.299 and start over
00:19:44.460 00:19:44.470 leave the system again thanks for
