    time for radiator hoses

    Its time for radiator hoses for the 86. Does anybody know part #'s that will work? I'm running the factory radiator that came with the diesel. I hope to drive it down the driveway today!

    The problem is at the radiator. The OD is 1-13/16.

    measure that one at the part store. Will the stock hose get even close to the water pump? You may have to get a different rad or get creative on making a hose adapter.

    I'll see what I have. It fits pretty well and angles down just like the f-body.

    The search is not going so good. We tried every hose NAPA had and little success. I think we will be able to come up with a lower but the upper is a problem. Those big ends at the radiator are a problem. If any ideas or part #'s...chime in.

    I thought about that. I also thought of using one from a Camaro or truck. I used this one because
    1-being a diesel it had the big radiator in it and bigger is better. Well, sometimes.
    2-I already had it.
    I have also had it cleaned out so I hate to trash it. Hoses should be simple stuff but thats not the case so far.
