    hey guys, first off: kudos to WESPAUL for locating an oil cooler for my '89. A heck of a nice guy and good to deal with. I'll be doing more business with him in the future
    I'm trying to pull my oilcooler but not having any luck. I've pulled the steering shaft, but still no clearance. I can't pull the cooler apart & need any help the experts on this forum can provide...I don't want to touch the exhaust manifold, my arthritis is acting up. Thanks!!

    No problem! If you need more clearance and you don’t want to remove the manifold, you’re going to need to loosen both of the engine mount nuts on the inside of the crossmember. Loosen them till they are at the end of their thread then lift the engine up on that side.

    Once you get it out (lifting the engine seems to be the best course of action in a truck), then here's a write-up of how to replace the o-rings.

    You can get the front header off and pull the oil cooler thru the back, but the problem lies in reinstalling the oil cooler assembly. You won't have the arm strength to smush the headers on in the engine bay. It's really hard putting the headers back on with new o-rings straddling the crossmember. You'll need a jack or press (carefully pressing, without cutting the o-rings).

    I still wouldn't recommend it. It's WAAAY easier to assemble it out of the truck/van instead of underneath it.

    That sounds like a good way to cut your o-ring seals. If those headers are not perfectly lined up, the metal lips on the cooler and inner header will clash and cut up the seal. A pry bar would need to be compressed perfectly, and I'd be impressed with the man that could do it regularly.

    i've done the install front header on the block assemble bundle and rear header with hydraulic press. install the o-rings on the bundle for the front and use a porta-power to pop it into the front header. requires shop level tools but gets the job done every time.
