GregZ,

I appreciate you taking the time to post the correct way to install the housing. However, you can do all of that and it may still leak. Been there and done that. After my second installation leaked-using the same procedure you outlined almost to the word-I checked it carefully and found about 1/8 inch warpage. I put it on a belt sander, got it flat, then used a regular paper gasket and have not seen a drop of coolant since. -Bob
