VW Jetta / Golf Oil Cooler Leak MKIII

[@ragingbull5883]

I saved your video years ago to work on my Mk2/Mk3, and then later I bought a Mini and still use your videos, it took me so many years to figure out it was YOU

[@ModMINI]

Oh interesting.

[@TvvinkleToes]

I’m definitely relieved to have found your video.

[@AndrewSLRC]

Thanks for this video. I did the job today. Left it a little late because by the time I diagnosed it, oil was literally shooting out of the seal. The gasket was completely snapped. Anyway, it took me a bit longer than you suggest, because I did it cold and the cooling hoses were really tough to work around. Nevertheless, it was possible. I needed assistance just for the step of getting the oil cooler unit the last centimeter off the filter nozzle. Me tugging on the hoses from below, my assistant pushing and twisting from above. As hard as that was, I was mortally afraid it wouldn't go back on again, but it did rather more easily. About 75 minutes total. So thanks again!

[@ModMINI]

+AndrewSLRC Good to hear. A common problem with these cars that can be easily fixed with the most basic tools.

[@slugworth1987]

very clean for its age that jetta

[@ModMINI]

Slugworth 1987 I detailed this one to sell it so maybe it looks cleaner than it really is. I've seen cleaner and I've seen worse. :-)

[@nannattack]

I'm so glad I decided to watch your video half way through doing this repair on my 1997 VW Cabrio, since the dealer parts department had already closed for the day. I had a really hard time getting the housing unit off but that could have been due to the hoses being cold. Took me a couple of hours total with oil change. Mostly spent it on trying to take off the unit. Using the oil filter gasket was a great catch!

[@wilburwhateley2683]

I did exactly as you prescribed and it seems to work insofar as I observe no leaks. So glad I watched your video and thank you for uploading. Now the crucial test: driving 200 miles home.

[@stopusingmyrealnamefk4276]

Worked great on a MK4 Jetta 2.0. Thanks, saved me lots of trouble.

[@dartii62]

you used a seal from an oil filter and it worked great?

[@polakadude]

Awesome, thanks for taking the time to film and post this. I have the exact same problem on my Golf. Now to actually go fix it.... :/ haha

[@ModMINI]

No problem. The whole job takes under a half hour - you'll spend more time worrying about it than actually doing it. :-)

[@soulwam]

Many thanks, I have done the job on my Golf AGG engine . Heating the water system was essential and I also found it necessary to remove the upper water pipe from the the oil filter interface mount to allow sufficient movement. The socket used was a simple 27 MM. box spanner, and the seal replacement came from a Citroen 2 cv filter as I had no spare for the Golf.

[@markstanton6461]

Gotta do this in a day or so. The &$#@& tow truck driver, after getting a call that the vehicle had an oil leak, decided it was best to start and drive the car onto the flatbed and then to drive it off as well. Kudos to this tech for thinking out of the box and discovering and reusing an oil filter o ring because its the same size.

[@kystout4425]

Thank you so much, A clear, precise, and ingenuity video

[@jesusedierhernandez1526]

man god bless you,you save me,im almost loose my job,for that

[@ModMINI]

jesus edier hernandez Good to hear - very important to keep vehicles in good running order and do the preventative maintenance if they are essential to your job.

[@tyte90]

Good video and tips. Thanks for posting.

[@zestyjobe]

This was a huge help, thank you for the vid!

[@sellwinerugs]

Great video. Thanks for sharing. I will need to make this repair myself and this is very helpful.

[@badmoonrison7563]

I had to replace mine on my 97 Jetta twice. They always burst when it was REALLY cold.

[@disisdynan5265]

Jonah Delisle same here! I got the same car and It just happened to mine.

[@TheLEAB]

Thank you very much. Great job.

[@ektofre]

Thanks!

[@al3xsad]

thanks, I needed this !

[@ktm250sxUbeazy]

I tried doing this by removing the hoses because I did not see the nut. that was a nightmare

[@YushuaNoureen]

this is pretty much the same process for a mk4 2.0 jetta as well ?

[@ModMINI]

I would imagine it's identical process.

[@ultra93srbIN]

At the 1.6 ABU engine is much more accessible to replace the filter :)

[@ModMINI]

ултра93србИН I usually work on MINI Coopers so this is pretty wide open compared to what I am used to. :-) Seriously though - you're right, there is a lot of stuff right around the oil filter, you can't even get the wrench on it straight.

[@luisalavezsandoval9358]

Great video

[@sniperpaintcorrection]

I have foam and exhaust gases in my coolant reservoir. Is this because of the oil cooler failing? I have no leaks showing anywhere . Oil looks clean .

[@KnottyAndNerdy]

Hey, so my jetta is leaking from the TOP of the oil cooler, not the bottom where the filter is. Is there another seal up on top, or should I look in replacing the cooler, its self? I'm not super car savvy yet, but buying an older car, after moving to a new state, has helped me start learning a lot, real fast, since I'm kinda broke.......

[@shaggybuddzz]

Nice video.....can I ask a question? The question is why the oil cooler flange; my Audi currently has oil in the coolant system and the mechanic I have repair my car said its not the oil cooler, turbo and something else but I forget......he thinks it's the head gasket, but the oil is fine zero color ,the oil cap is clean and the engine runs fine never getting hot.

[@ModMINI]

What do you mean by Why the oil cooler flange? Are you asking why it exists? Oil could get into the coolant but not the other way around because the oil pressure is higher than the water pressure at the location of the leak. It's entirely possible it could be head gasket.

[@shaggybuddzz]

Mod MINI sorry i was copy and pasting and didn't notice I copied flange..I was hoping my car had a bad oil cooler or oil cooler flange....but after many dead ends it seems too be the head gasket....

[@timboslice9643]

I replaced my oil cooler o ring and we accidentally broke something inside the oil cooler and oil mixed into the cooling system. So we went to pick n pull and got another oil cooler and flushed the system and oil keeps getting in the antifreeze. Do u think the second oil cooler I got from pick n pull was bad too?

[@ModMINI]

timbo slice You could be still seeing leftover effects from the previous oil cooler failure. Or, you have a bad head gasket?

[@timboslice9643]

***** I just had the head gasket tested. And I've replaced the hoses radiator and water pump and there's still a lot of oil in the cooling system

[@freestyleXX111]

You need to flush ur coolant system before you replace it ..

[@krysbrandonlestat9873]

I have a 95 vw Cabrio same motor I was wondering did it leak any cooling fluid when u took out the rubber seal ? Did u disconnected any hoses bro ? Just wondering I been wanting to chance that part It would help alot any info in it bro Thank u very much

[@ModMINI]

This car did not leak coolant.

[@krysbrandonlestat9873]

@@ModMINI thank u bro

[@coreygordon8449]

How long has the oil filter ring last for you ?

[@ModMINI]

+Corey Gordon I sold the car to my friend, he hasn't had any issues with it so far, so it's good for at least 18 months...

[@DeadSpaceman2012]

Bunch of hoses in the way underneath the coolant hoses on my 96. Do I have to remove the threaded tube or unhook all the hoses? Any recommendations on how to do that?

[@ModMINI]

It's been years. I think I didn't disconnect hoses.

[@DeadSpaceman2012]

Mod MINI thanks for replying. I managed to force it down far enough to get it off the tube. So far so good! No leaks! Thanks for the video man!

[@KenDeavers]

You forgot to tell people to put oil back in the car 😬😂

[@cartoonz_mk3658]

what's the socket wrenchs name that u used

[@soulwam]

Hector Ortiz I used a 27mm box spanner, a very simple and economical tool.

[@josepeixoto3384]

Wrong gasket there for sure,that you used; Oil filters are meant to be tightened by hand,NOT compressing the VERY THICK gasket all the way; the oil cooler O'ring needs to be the correct (less) thickness because it will be tightened with a wrench,and all the way to a pre-determined mechanical stop; That oil filter gasket runs the risk of extruding out or shearing,now...or *LATER* ! Sorry,but i am EXTRA careful with these things because i install these and other diesel engines in boats.

[@Fibonacci4ever]

Nobody paid any attention to your comment yet bcuz the hack worked perfectly for everyone who tried it. Sometimes when you think you need everything to be perfect On Paper, what you really need is a little dose of reality, which is far more In Color than the Black/White nature of looking good on paper 👍🏻

[@jovitmaca]

what size socket did you use to get the oil filter housing off.

[@ModMINI]

Sorry don't recall, probably a 36mm?

[@soulwam]

Josse my golf AGG has a 27mm nut and it is likely to be the same.
