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 found it a bit difficult to get to the lower front mounting bolt. I removed the serpentine belt and loosened the 5 power steering and alternator bracket bolts and slid it forward for more access to that lower bolt. On re-install I loosely tightened the 3 rear bolts at the filter housing and that greatly helped getting the front aligned to get the two front bolts started. Then I torqued them all down.

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).

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?
