Anyone know where I can find GM PN 15725587 ? This is the oil adapter with hoses used for oil coolers on GM trucks. i want to modify this for an oil cooler.

I'm not having much luck finding it.

Any help or suggestions.

LGM has a custom machined billet adaptor that attaches just above the oil filter.
It has -8 fittings coming out the top.

Here is how I installed mine ...

Thanks Mitch, Actually looking to get away from that set up and cost associated with it. I'm looking into this http://www.noid.org/oilcooler/

However, I get the impression that its no longer available from GM.

Anyone know which trucks these were standard on? I could pick one up at a salvage yard if no longer available new.

Thanks

What about something like this:

TCI oil filter "sandwich adaptor"? Is that what you're looking for?

Perma-Cool makes kits to relocate the filter and adapt up a cooler;
the TCI adaptor leaves the filter in the stock location (-1/2").

I went looking for this part at the dealership.
It has been superseded by P/Ns:

15203890 (truck oil cooler adaptor)
15203889 (gasket)

As of 20040819 these P/Ns are showing up as
good on gmpartsdirect.com and Scoggin-Dickey
(http://www.sdpc2000.com, sponsor).

This adaptor is meant to use the in-radiator
oil cooler on the trucks but I reckon a flare
to AN (or whatever) would do the job if a
flare-style cooler cannot be found. If anyone
knows of a good 6"x9" (or so) compatible
cooler, tack it on here....

Doesn't the GM oil cooler adapter also have a termostat built into it?
