Leaking Oil Cooler Lines
#1
Hello everyone - long time since I've been able to get on here. Hope everyone is well, and your cars are all running problem free!

I recently noticed an oil leak from the cooler lines where they meet the cooler. Being a poor student I ordered the cheap dorman part which *knock on wood* seems to be holding. This phenomenon is of course no secret to anyone, it's a common thing for the o-rings or the crimps to start to leak, especially since that area gets splashed with grime and road salt many months of the year.

Anyway, long story short if you're ever doing this repair, freezing your butt off in the middle of february, check to see if this repair has been done in the past, and if the last person to do it screwed it up. I had read beforehand that some people have easily stripped the pinch bolt at the cooler-end, and have drilled straight through the cooler, securing a bolt with a nut at the other end (in a space that was never designed to accomodate it). I was changing my oil at the time, and didn't realize this bolt fell into the drain pan. I spent a good couple hours cursing and freezing before I decided to call it a day, drained the pans and figured out what had happened. So much for a quick simple job.

Hi, the cooler line is a good thing for cops because the engine run over time in idle. In your case, buy the adapter w/o cooling line and throw away this parts and you would never have leak. Doorman or the oem parts at the ford dealer, its the same piece of shit.

Mine were leaking on the 96' Vic. I replaced the o-rings with a pair I got from Crappy Tire and all has been well since.

I agree with you 100% my friend. Just get an oil filter adapter and a lower radiator hose from something without an oil cooler. Maybe $75 in parts, and it will never leak ever again.

I did this on my car and I am glad I did it. If you ever had any questions about it, feel free to ask me.

Yeah I was actually going to replace the o-rings on the ford part I took off and put it back on there. Just couldn't have any down time with the vehicle lately - no backup car and midterm exams galore.

I don't even mind replacing a leaky hose once in a while. I bought this car specifically because I could be hard on it, both for work and play. I just don't like the thought of my adulterated oil cooler!
