Be sure to check the hose coupler at the block near the OFH. That is the plastic fitting that cracks or blows apart.
Also when replacing with the aluminum part, make sure to use a new o-ring and that it goes in straight and doesn’t get pinched. That’ll leak for sure. (Ask me how I know - doh!)

I always recommend a bit of lubricant on any o-ring, just a bit on two fingers and run over the whole o-ring. I use white lithium grease.

Sorry to revive a dead thread. Dealing with coolant boiling through the res cap so suspecting a water pump is in my future.

How’s the Piersburg aluminum one treating those who have it?
