When pressure testing the coolant side of the cooler,Think 20lbs is enough to pressurize it ? I think that's what's put on the cooling system when pressure testing it from the expansion tank ?

i just repaired mine yesterday and i took the cooler out from the bottom. i reached through above the frame, from drivers side, to get the front two bolts. i got the three rear bolts from underneath. take off the oil filter and wiggle it and twist to remove it from below.

It looks like you don't want to put over 20psi when testing. I found this thread and sounds similar to your problem.

I'm gonna post some picks of the O rings . I had them under a microscope and used my camera through a magnifying glass to get the pic . I only had about 2 quarts of coolant in the pan based on the dip stick (1 inch).

If you look at the seat line it looks as if it's bypassed in 2 areas on this O ring

the problem with my cooler was rust, you should replace the seals and gasket then put it back on and see what happens. do you have access to a press? its hard to put the ends back on putting it back together. do you have acces to a press?

place the cooler vertical on a jack and press it against something stable when you need to put it back together

Nice idea !! I can do that. I'll have my kids sit on the kitchen table and jack it up against the underside of the table . Think the wife might get mad
