    yup...

    Rule # 1..never destroy old parts that were still working!(even if they leak,etc!)..especially on a sunday!..:doah: ..


    I've seen guys peel back the crimped portion of the OEM hoses and cut the old hoses off with a razor knife,there is a barbed fitting under the crimp--then they use new bulk hose of the proper type and size on the original metal tubes, and hose clamps to secure the hose(the same way you can fix an air hose in the shop when a crimped fitting fails).....trouble is,up here the tubes rotting away is the main reason the hose fails,not the rubber!...

    I think GM hoses are cheap crap,and way overpriced!..hard to get too..I usually have new hoses made at a hydraulic hose shop-- much cheaper,and you end up with far better quality hoses and fittings..seen many S-10 mptors blow when the oil cooler hoses fail,and the owner kept driving until the motor was junk..:doah: :crazy:

    I used steel braided hose, AN fittings and flared the old aluminum ends. :deal:

    yep dont trash old till verifyed new is correct and in hand.

    and 2 bolts is all that holds cooler to block. you could have just droped the filter/cooler adaptor and swaped motor. .

    I've had new rubber installed on the factory parts at a shop that makes hydraulic hoses. Cost less than $30 to have both hoses fixed up better than new. :cool1:

    Flared the old aluminum ends? Anyway, I used steel braided hose and AN's as well. If the hose ever goes bad I can just buy 6 more feet and swap the ends. Reuseable fittings rule :D
