    88 Oil Cooler and Hose p/n\'s ??

    Took my 88 out today across a local 4 wheel trail to check things out. About an hour into the ride I stopped to stretch and noticed a bunch of oil dripping in front of truck. I looked it over and the oil is running all along the lower radiator tray and fan shroud. The lines looked wet with oil but not dripping. I looked at the cooler and its looks wet with oil too. Looks like someone had changed the lines before cuz theres 2-3 adaptors between the hardlines and hoses. Priced cooler at Autozone for $110 !!

    Does anyone know the GM part numbers of the cooler and hoses so I can do some checking around?


    Oh yea...also discovered front right axle seal is leaking /forums/images/graemlins/frown.gif

    Another idea, talk to the local hydraulic hose place.

    They can build the "armored" lines (steel covered or steel braided rubber) with the correct fittings *typically* for very cheap. I almost guarantee, if GM can still get them, they won't be cheap.

    IMO the later oil cooler lines, plain rubber hose to steel ends, similar to the AC lines, are a bad/cheap design, that tend to fail more often than the "older style" steel braided lines. Got a couple of the armored steel line setups running on a couple of different trucks, and they don't leak.

    Thanks for the help!
    I called the local GM dealership and got a P/N of 12546251 and a price of $265 /forums/images/graemlins/eek.gif

    I then located a local radiator shop that also repairs aluminum radiators etc. I dropped it off at lunch for them to evaluate. If it can be fixed, $30 /forums/images/graemlins/thumb.gif

    I cleaned up the lines and they look pretty good. I do agree, the amount of fittings and adaptors GM uses is pretty poor design. Actually thought about replacing them with barbed ends and standard hose with hose clamps.
    I never thought about having lines made up, that a good idea.

    Thanks for the comment on the "small" picture, I guess your referring to the U-2 pic I have by my sig. Ive worked on that aircraft for years, pretty amazing what it can do.

    Ciao /forums/images/graemlins/grin.gif

    Glad you got it fixed.
    If you ever need to replace it.
    B&M makes a stacked plate cooler Exactly like the stock one except it has 1/2 inch NPT threads. You can get adapters from most Hyd hose shops To hook everything up.
    Its called The super cooler. I bought mine from Summit 59.00
