Oil Cooler Hose Issue...

[Ocnaj]

I have a 90 with a little problem. For some reason the small U-bend hose by the oil cooler leaks. It is a brand new hose along with brand new clamps. The cooling system also has many new parts like a water pump, HD t-stat, all hoses, seals, etc. It seems that there is more pressure down where the U-bend is than there is supposed to be. I can't figure out why it leaks. Please help...:cry: Thanks in advance

Is it leaking at a seal? Are you sure it is clamped sufficiently?

 

[K-Dawg]

Just to be sure, it is coolant that's leaking?

Sure its not leaking from somewhere above and draining down? Like with all mystery coolant leaks, borrow a pressure tester from AutoZone and find exactly where the leak is located.

I am positive that the U shaped hose by the oil cooler is leaking from the top of the hose, not the bottom. Is there a way that I could lower the pressure in that hose?

bump...

is it leaking at the clamps? are the fittings that then hose seals on pitted or inn bad shape?

No you can't lower the pressure. It may be leaking at the hose ****** as it leaves the block.

Yes, for some reason it doesn't leak all the time. The fittings were as clean as can be when I put the new hose on. I took the car to the track tonight and it didn't leak once... I don't understand these cars sometimes...

Check where the threaded ****** goes into the block.

How did you do at the track????

I'll check it out tomorrow. My best run tonight was a 14.71 @ 94.96. The fastest I ever ran in my 90' is a 14.66 @ 94.51 last year. My last run was a 95 mph trap speed but my right tire broke loose off the line and got a 14.93. Not bad for just a custom catless y and a dynomax catback I guess...

SWEET!!!

You need to stop by my shop sometime. I think you will enjoy it.

Of course! I'd like to learn how to do more maintenance on these cars too.
