Did you pull the thermostat housing or hard pipe? I pinched the o ring putting mine back on once and it leaked coolant.

Just checked out my hard pipe but there's no leak around it but I did pull the thermostat housing off but I don't see any external leaks around that area unless its internal

I had a leak on mine that developed where the water pump bolts to the oil cooler.

It came out to be the thermostat housing gaskets both sides were worn out pretty bad but I got it taken care of and now it's running pretty good with no leaks.

thanks
