454 Oil Cooler Adapter removal - How??

[vette_dude]

I am working on a friend's '90 3500 4x4. It is leaking at the oil cooler adapter. How do I remove the adapter? My stepson got under there on Sat and removed one of the pipe plugs on the bottom of the adapter, but saw no bolts. This is leaking pretty bad, so we need to get it removed and new gaskets installed. The Chevy Service manual was useless. Can anyone help??

my 78 454 had two allan head bolts holding it on.

Where were they? under the pipe plugs???

inside under the filter.straight across from each other

On this one ('90 454), the filter is moved to the side so it goes in at a 90 degree angle (horizontal) from normal.

It is held on with bolts under the pipe plugs. I recently rebuilt a 1990 454 with that exact cooler adapter.
IIRC the bolts were torx head.

Scott -
thanks for the info. you remember very correctly. it was indeed torx (T40). But the front bolt requires a long (3""+) extension to get to it!! So I dont quite have it off yet... this weekend.. again thanks for the info..
