I just installed the new Dorman aluminum housing on my 2011 Dodge Grand Caravan (Pentastar).
Be VERY careful when inserting the aluminum pipe into the engine block! I was 100% sure that I did it right at 90 degrees. While tightening all screws in the suggested order, the metal pipe marred the surface inside the engine block badly, and exactly where the o-ring sits.
This was never an issue with the OEM cooler housing since this is all plastic.
I spent 2 hours refinishing and polishing the inlet in the engine block with a Dremel to prevent any oil leakage. I tested at idle so far and it doesn't show any oil in the valley. We will see if its starts leaking at higher oil pressure.
The placement / machining of the aluminum pipe on the Dorman cooler housing seems to be off slightly, and a tad too large in diameter, making it hard to align right without damaging the engine block. Be VERY careful!
