sandwich oil cooler adapter and oil cooler questions Options

[type47]

After track sessions this past weekend, oil temps as indicated by a dipstick thermometer (Mainely Custom item) indicated temps of about 252 F after 20 minute sessions (ambient temps in the 60's). The engine is a Euro D-Jet with 20-50 Brad Penn. The engine that was in the car when I bought it (not the same engine as in the car now) has a sandwich oil cooler adapter and the oil cooler is still mounted on the car and I think I will hook it up again. Two questions; first is the indentification of the outlet and inlet on the adapter; which is which or how do I figure out which one the oil should exit from and which should the oil return. Second, on a radiator style oil cooler, do you hook it up so that oil goes in the "top" and filters/goes down the coils and exits out the bottom connection or goes in the bottom and pressure feeds up the cooler and exits out the top to return? TIA

My sandwich adapter has an arrow cast into it's side, and the instructions showed them as well. Perhaps you could look at the manufacturer's website for online manual?

Oil coolers should always fill from the bottom and exit from the top or they won't fill completely.

Good Luck!

Note: My sandwich adapter (PermaCool) raises my oil pressure by quite a bit. Does yours?

I drove the car with the original engine with the adapter about 5 yrs ago so I don't remember the pressure status and for that matter, didn't drive the engine w/o the adapter. I will let you know if I notice any difference after I install/re-hook-up the cooler. Thanks for the answer to my questions..... will hook it up maybe this weekend...
