Here is pic of my new 3" X 12" oil cooler with Perma-Cool T-stat that I got mounted and rigged to the 502 Mag this weekend.

Looks good.
Where did you get the cooler?

I just ordered a couple PermaCool oil thermostats from Summit. Pt. #1070 for 1/2 in npt 38.00 each. Where'd yuo get the fittings and hose. Looks good.

What are you using for a power steering cooler?

The cooler came from Marysville Marine via my engine guy. It looks to be the same thing as one from Eddie Marine. I got it for $170 plus tax.

I got all of the extra fittings and hose that I needed from a local Parker store. They sell hydraulic hoses for construction equipment, farms and anyone else that needs it. The brass 90s came from the stock setup. The hose is Parker #836. It is a high temperature hose that is rated for 300 degrees and 250 psi. It is made for Push-Lok fittings which I highly recommend. The hose is not cheap ($6/ft) but the fittings are. $2.02 for the plain straight and $2.77 for the ones with swivel ends. The adapters from 1/2" NPT to 37* are $1.49 each. I used 5/8" hose (10AN).

I have a 2" X 5" cooler for the power steering in the hose going up to the T-Stat housing. That was easy.
