4age oil cooler pressure relief

**fandio** · 15-06-2011, 01:27 PM

Just seeing if anyone know the pressure that a stock 4age oil cooler pressure relief valve opens? Can't seem to find it anywhere

70psi is the normal relief.

not sure WHEN the change occured, but if you use the 19036 pump you'll be using the newest

Those pumps above are both big port pumps. Small port pumps have a lot more sharper teeth.

I see. I was going off this. Which I see in that thread to be backwards.
