VW B5: 1.8T Passat oil cooler seal replacement

[@kylemiller6639]

thank you soooo much for this tutorial! my original o-ring blew last week on my '98 Audi A4 B5 1.8T 227K miles. the one day i was actually early for work so i let her warm up before leaving - she vomited all her oil just idling so i was lucky not to be on the road when the oil pressure light popped on. test oil: walmart syntech 5w-30 $17.00/5 quarts: to fill, start up, and watch the oil spew out between oil cooler and housing Audi OEM O-Ring/Gasket PN: 038-117-070-A $6.40 + tax Lowes Kobalt 27mm deep socket: $8.53 + tx - DID NOT NEED. will return. regular socket fits - there is only about 1/2" of threaded oil pipe exposed after oil cooler is in place. notes: -i thought this was an oil system / engine disaster until i found this possible root cause. -retaining nut was completely loose. i've never checked before or even thought about it. -A4 has a reservoir to the driver's side of the working location making manipulation more difficult but i did not have to remove oil cooler from coolant supply hoses. -project gave me a chance to replace belly shield - i just zip-tie them to bracket and wheel well location holes - much easier than crap Audi superspecial fasteners that continually get lost. one Q: do you know if A4 came with any sort of OEM protective plastic tray insert to cover battery etc between the 2 firewalls? i can't remember and wonder if at some point a service person just chucked it into the bin.

[@EXOVCDS]

Thank you for the detailed run-down! Happy to hear that my video was of help! You are correct, the deep socket is not needed... personal preference. Yes, I'm pretty sure there should be a plastic cover similar to what the Passat has.

[@pauliekruger7639]

I understand all the variables. Very good job you did for us. It helped me out today. Mine was leaking only because the pipe was loose. Thought it was the o ring but all’s changed and good now. Thanks!

[@EXOVCDS]

It's a good idea to always check the tightness of the nut at every oil change.... and the tightness of the pipe. =)

[@comingundone27]

Just gotta say your videos rock man.

[@EXOVCDS]

Nick Palmer Much appreciated! All the best to you & yours for the new year!

[@joecharron3984]

Great video. Same the happening to my 2001 VW passat

[@robertgreenfield9051]

This will be my second time changing this seal on my 98. last was 10 . Perhaps I'll do it as a maintenance item every 5 years. So easy with an oil change

[@EXOVCDS]

They do seem to not last as long these days... I check / tighten the nut at every oil change, but as soon as I see oil seeping from behind the cooler, it's becomes a recommendation for the customer.

[@stuzman52]

I know that I posted a comment just awhile ago, but didn't see it get posted. Anyway, I'll post it again. Amazing how an owner can let oil squirt out and let his engine get dangerously low on oil to possibly have engine damage. Nice work Thomas on replacing the seal on the oil cooler, ah, I mean heat exchanger HaHa! And could you tell me how much oil my car needs? LOL...take care Thomas!!

[@EXOVCDS]

Over the years we went through a bunch of guys... they all left for "bigger & better" things. I can understand a customer wondering how much (because they don't want to buy too much at the store), but when you have a coworker ask you, WHILE he's pouring oil into the funnel... that takes the cake! Sigh!!

[@TheDisgruntledMechanic]

tight to tight but not too tight to be over tight! now that is a factory torque spec!

[@EXOVCDS]

What's the other saying? When the bolt starts to feel loose again, you've gone too tight! LOL

[@TheDisgruntledMechanic]

I like the saying my friend told me about tightening stuff" tighten it until it snaps off, back off a 1/4 of a turn and you got it!"

[@EXOVCDS]

LOL!

[@stuzman52]

Hey Mike, I've heard the saying like yours too, but another one goes like this. Tighten it as tight as you possibly can and then go another 1/4 turn :)

[@EXOVCDS]

stuzman LOL!

[@StopDropandLOL]

Yay! New Thomas videos. I was having withdrawals from last week!

[@EXOVCDS]

Should keep you busy for a little while. =)

[@cemanadis]

love your videos. Nice time saver also good for DIY first-timers.

[@EXOVCDS]

Thank you and thank you for watching!

[@pauliekruger7639]

Panties in a bunch. My oil drain bolt was a 19mm, not a 17. But it would be good to inform or warn folks that the pipe that holds everything in place can be loose. Probably not a factory first time at my point. So I was surprised when I had everything out and I needed to tighten the pipe back up, and you need a " 3/8" internal pipe tightener to do the job or you' ll be stuck at home and need this tool to finish this job. And my VW dealer looked up a heater core gasket when I said "Heat Exchanger. LOL.

[@EXOVCDS]

Too many things to talk about (possible differences, what can go wrong, what to look out for etc)... I record while I'm at work. Besides, that's what the comment section is for!! =) OIL COOLER!!!! I wonder whatever happened to the guy that gave me hell about that. LOL

[@IvanIvanov-oq7wn]

Yes a full video. From the beginning to the end. If possible keep them that way. Saying " install everything in reverse off removeal " it left the feeling that the video is incomplete.

[@EXOVCDS]

I know what you mean... but even the factory service manual always says: Installation is in reverse of removal. =)

[@jazz4life]

Thank you so much for this video. Ending up w a lot of oil in my coolant reservoir. My indy told me that based on a pressure test that I don't need a head gasket. I have this part now and going to replace the cooler tomorrow and pray that he's right. Thanks so much for this video! By the way, what do you use to shampoo the engine? There's a lot of oil caked up on the cooler that I got off, but looks like some on the back of the engine block that I can't get to with a can of brake cleaner. I want to clean that too and see where it might be coming from. Either way, thanks again for helping make this job easier.

[@EXOVCDS]

Dawn liquid dish soap. I also run it through the cooling system on vehicles that have oil in the system. It can take 4 or more flushes till nothing but clean water comes out.

[@jazz4life]

@@EXOVCDS Thanks again for the reply. So to flush with the dish soap, I'd use that and distilled water and then let it run through the system on a short drive, then flush again, then repeat, etc? I got the oil cooler changed today. I think I solved my problem. On the inlet hose the coolant was still bright pink but in the outlet hose it was brown inside and you could tell oil was mixing with it. Finishing it up with a n oil change tomorrow and will be flushing the system then too.

[@EXOVCDS]

Yes.

[@kimnielsen4343]

My audi A4 1998 has the same problem.. it is pissing out of it and frist i thought it was the sump, then the filter but the leak is still There 😣 i Will try the oilcooler now, because its right behind the filter is coming from, and its wintertime her in denmark now so thanks for helping me connect the dots 🤗🤗🤗

[@EXOVCDS]

Yeah... most likely the cooler seal. This one squirted me right in the face! LOL

[@kimnielsen4343]

Thomas EXOVCDS des that 27 m has to be a deep socket?? 🙄

[@EXOVCDS]

Kim Nielsen Not really... but it helps.

[@kimnielsen4343]

Thank you 🤗 keep Them videos coming, and this Channel Will grow big time 🌱

[@EXOVCDS]

Kim Nielsen I just checked on a 1.8T, a shallow / regular depth socket should also work.

[@wizkid01]

Thomas, will you be doing any videos on oil catch tank installs?

[@EXOVCDS]

No.

[@bigfish7493]

OK...thanks...I'm looking for Inter-Cooler details. My 1.8t blows the pressure hose off the inlet to the IC. Assumption is the Cooler needs a bath . Thanks

[@EXOVCDS]

Clean the hose & cooler... both need to be nice & dry for the hose to stay in place. If it's a snap fitting, check for worn ears.

[@EXOVCDS]

3:43 27mm

[@kimnielsen4343]

Thomas EXOVCDS just ordinary socket, organisationer a deep one like the ones for sparkplugs? tank you for replying, i love rour Channel 🤗🤗🤗

[@EXOVCDS]

Kim Nielsen The 27mm I have / use is roughly 3" long. Thank you for the kind words!

[@bossman6290]

Thomas EXOVCDS thank you sir saved 200pounds👍

[@SteveRobReviews]

That was a crazy big leak it's a wonder it didn't run out of oil getting to you.

[@EXOVCDS]

Oh I think he was pretty well out of oil by the time he got to us.

[@MarianMoise1974]

Thanks for sharing your knowledge. Merry Christmas!

[@EXOVCDS]

Thank you for watching! Merry Christmas & all the best for the New Year!

[@carlhammill5774]

Excellent video. Which break part cleaner do you use - I thought its flammable...is that ok to spray on engine?

[@EXOVCDS]

Yes, brake cleaner is flammable... but it's great for cleaning stuff, because it dries quickly. You have to be careful where you spray it (stay away from hot exhaust and spark).

[@dawiddawid3280]

i have a oil leak in the same location but also have oil presure light on would this could be the problem??? help please

[@EXOVCDS]

Oil pressure light at idle or when rpm reach 2000? When cold or when the engine is warm? Oil pressure switch is just above the oil cooler... your leak could be the cooler seal or the pressure switch.

[@toddwilliams9681]

Would this be a fix if there's coolant leaking into the radiator & 3:36 reservoir or do i have a head gasket problem

[@EXOVCDS]

If you have oil in the cooling system, then the oil cooler might be bad. Replace the oil cooler and the seal / O-Ring. Flush the cooling system of any remaining oil. Fill with fresh coolant. If oil returns, then it could be a bad head gasket.

[@toddwilliams9681]

@EXOVCDS yeah just ordered a new Cooler God Willing That's What It Is!! And I flushed the system out today but a another 1 won't Hurt

[@toddwilliams9681]

@EXOVCDS sooo changed the oil coller & put fresh oil & coolant I got a Bad head gasket 😩😮‍💨

[@EXOVCDS]

@toddwilliams9681 Sorry to hear that. Did the engine ever overheat in the past? Head gaskets usually don't fail for no reason.

[@toddwilliams9681]

@EXOVCDS never over heated, still hasn't! Dam oil just keeps mixing w/the coolant 🤷🏾

[@bjornnickander682]

Really good Video and tutorial! Thanx alot man!

[@EXOVCDS]

Thank you for watching!

[@sparks6666]

Great vid as usual. Can you go into detail on how/what to use for shampooing the engine. Thx!

[@EXOVCDS]

Rich Wachtel Buy engine shampoo... spray engine... soak... wash off with water.

[@ΓιωργοςΖερβακης-β9ψ]

Is it possible the oil radiator to broke down? I have oil transferred to the water radiator and water in the oil radiator and hoses.. I have already changed it twice in the past but not with the original part from VW..I have a Passat 1,8t 20v my 2003..

[@EXOVCDS]

You can pressure test your cooler: kzbin.info/www/bejne/jX-8qWeOn9drY6s

Do i need to remove coolants first?

[@EXOVCDS]

If I didn't remove coolant, then you don't have to. If you are replacing the cooler, then yes. If you are only replacing the upper seal, then no. I don't know what you are wanting to do, so I don't know if you have to drain the coolant. If you are replacing the cooler, just disconnect one of the coolant hoses from the cooler. You will need to remove the belly pan / engine splash guard and you will need something to catch the coolant... and the oil (some oil will drain out when you remove the oil filter). It's a good idea to watch the video several times... to understand what is happening. Year, make, model of vehicle you are working on?

[@scottisizzle]

Have you ever heard of an oil cooler breach, I which water and oil mix? Ive put two head gaskets on and im still getting water in my oil! First gasket made it about 2000 miles before it started mixing. The second one I just put in 50 miles ago, and i have water in my oil this morning. I've followed factory specs on installation. Im using Felpro gaskets. I even turned it an extra 1/4 turn this past time. Im losing my mind over this thing and I cant even get any answers from the forum that im in. I thought maybe I didnt scrape the block well enough, so I was thorough this time.... I wouldnt think that water would enter the oil through the cooler because oil pressure is higher, but im at my wits end with this thing. I love this little car and dont want to except defeat. Please, please, please help me!

[@scottisizzle]

Could it be mixing in my turbo?

[@scottisizzle]

Although, I'm convinced its something to do with my head gasket. I checking other options. This is the third gasket ive put. The very first one I put in did start doing it as well around 2000 miles, but I had a hose come off and it did get hot, so I assumed it was from the heat, but the head wasnt warped when I had the machine shop inpect it. And yes, I did have it resurfaced the first time. Checked every time since.... Maybe I need factory head bolts???

[@EXOVCDS]

@@scottisizzle year, model, engine? Bad oil coolers will leak oil into the cooling system (oil pressure is higher, like you said). I would think that the same applies to the turbo. A cracked block or head would be my guess.

[@scottisizzle]

@@EXOVCDS 04 1.8t GL I believe. Front wheel drive.

[@scottisizzle]

Only reason I would rule out cracks, is because its not happening right away. And i havent seen any visible cracks. The head was tested the first time I replaced the gasket.

[@audimanao]

dang i didn't know the oil sprays out like that, what mileage does this leak normally start

[@EXOVCDS]

audimanao Could start below 60k miles or could happen later. The nut can loosen over time (due to seal flattening or nut loosening when removing the oil filter). Every time the oil filter is changed... check if the nut is tight!

[@moayedhamed8613]

I have a Skoda Superb , the first version, and I changed the engine to a Passat 2004 1.8t, and now there is a crackling sound at the top of the engine head. Is it a problem with the oil pump or the Tensioner gasket?

[@EXOVCDS]

Probably the tensioner... low oil pressure would turn the oil light on, no? Post a video on your channel so that I can hear & see.

[@kimnielsen4343]

it sounded like a tractor when i startet it up again, but it got quiet after a good fill-up and a testride.. My question now is what soap to use to clean the engine ??

[@EXOVCDS]

Most auto parts stores will have engine shampoo or degreaser... spray engine / area and wash off.

[@n9wox]

Gasket on my '00 hasn't failed yet with almost 300K, but I'll buy one just in case. Is small amount of dried coolant residue where hoses attach to heat exchanger normal?

[@EXOVCDS]

Any sign of dried coolant is not normal / should not have any.

[@rafaelperdomo2182]

excellent, thank you. i want to buy a 2005 vw Passat wagon with a 1.8t. Can i bring this baby to good form or it's going ti money pit.

[@EXOVCDS]

15 year old cars will need some TLC... a money pit car would not make it to 15 years (I think).

[@EXOVCDS]

[@cameronyoung2004]

Whats the part the the gasket seals against called? Im having a leaking issue from there.

[@EXOVCDS]

The oil cooler is mounted between the oil filter and the filter flange. The oil pressure switch is mounted to the top of the oil filter flange... could be that the oil pressure switch is leaking.

[@cameronyoung2004]

@@EXOVCDS I had removed all of that. Yes it was the oil pressure switch that was the original leak. I replaced it. Now I have another leak. I suspect it's the part that the oil switch screws into and attached to the engine block

[@GreyForrest]

What if my sensor thingy has oil all over it and isnt dry like yours?

[@GreyForrest]

mine has gotten so low twice now without any warning light also that the engine almost seized. Mine appears to be leaking somewhere in heat exchange area, but that plug back there looks drenched in oil. could just be from the seal leaking so much back on it??

[@EXOVCDS]

Could be the seal or the pressure sensor. Clean it off and then start the engine... you should be able to see where the oil is leaking from. If in doubt, replace the oil cooler seal and the oil pressure sensor.

[@GreyForrest]

Ive still got a damn leak down there somewhere.... If i replaced the dipstick tube, should i have place any type of RTV around the base or is it just a straight connect? So far I have replaced the valve cover gaskets, whch did help, the crankcase vent vale which fell aprt, and the dipstick downtube and dipstick that were decetergrating.

[@EXOVCDS]

What engine? 1.8T? Like I said, once everything is clean (wash the area with engine shampoo / degreaser) it should be easier to see where the oil is coming from. Dipstick tube is just a press fit, no need for sealant. You can add a dye to the oil and then use black light to see where the oil is coming from (the dye will glow under black light)... can be bought at most auto parts stores.

[@GreyForrest]

yes, 1.8t

[@zoidberg444]

Holy shit. Really not an engine to run low on oil if you ask me. I have seen engines miraculously survive being run on no oil. I saw a V6 jag S type driven on a 70 mile round trip on the motorway by a guy who thinks hes the stig without a drop of oil and survive with no detectable ill effects. We shoved a bottle of oil in it and it lasted another 4 years/40k before being written off in an accident.
