Engine Oil Cooler Lines

Engine Oil Cooler Lines

Postby coult45 [OP] » February 3rd 2015, 9:40pm

So I went to pull off my leaky oil cooler lines today. After buying some new pick tools, the radiator connections went off easy. As did the connecting bolt to the oil filter. But, theres another bolt, which attaches a metal "ring" to the engine block. After watching youtube, and reading my FSM, this was supposed to be super easy.

Turns out both youtube and the FSM have instructions that follow the RWD model, i have the AWD so there is a giant front differential in the way of my bolt! I ended up removing the front driveshaft, hoping I'd have better luck getting a wrench up there, but its all pretty tight. I can sort of fit some wrenches, the video says its a 10mm, but that doesn't seem right, could it be a standard size bolt?

Either way, I cut off the ends near the filter side so i could pull the lines out without undoing that engine block bolt.

My question is, can I just move that engine block bolt/holder out of the way and run the lines from the rad to the filter? Or should I really try and find a way to get the lines bolted to the engine block? Any help getting to this bolt / what size it is? And any tips on re-routing the new lines back in would be great, definitely bent the crap out of the old, leaky ones..


On another note, I've thought about doing the cooler line delete. Any thoughts about the delete?

I deleted mine after they leaked and blew my engine up.
It is a good thing to have "IF" they don't leak. But it would be fine without them.

My 89 doesn't have an OEM oil cooler. I keep reading where everyone seems to have trouble with the hoses and connections with their OEMs. Is it always at the filter adaptor? What if we REMOVED the OEM adaptor and something aftermarket?

I can't ever remember having leaks in my VW external oil coolers and filters. Nor in any Frud Wambulance (nearly always aftermarket).

I just had mine replaced a few days ago at a local mechanic because it is a messy job and I'm glad I did now. They said for my AWD the easiest way they could find to do it was unbolt the subframe on one side and let it hang off the van somehow. It sounds scary but it's on there and the van is driving great.

By the way if you buy the dorman replacement ones they are $44 on Amazon which is way cheaper than OE

Woah! That was the answer i was looking for.... Maybe ill run it without lines and when I find a chunk of time put them in. The $44 dorman lines should arrive tomorrow.

And lumpy, mine are only leaking where the metal and rubber tubing meet. The connection at the filter is dry as a whistle.

My shop only chRged me $100 for the oil change and putting the lines on, well worth it for this job if you ask me.

Also another option is just fixing the leak by cutting the tubing off and putting new hoses with clamps. 97cargocrawler has a write up on that.

100 bucks -sold! I cut the new lines and put them together with a compression coupling. Be careful, but after around an hour of trying to install the new ones I gave up. 4 years later and no leaks
