Car: 2001 SLE Pontiac Bonneville with 184,000 miles, owned since new. Should I use a Dorman kit or parts from a dealer when I replace the upper intake manifold. Dorman kit contains all needed parts but I am concerned about its fit and durabilityl


Asked by Aug 31, 2015 at 09:39 PM about the 2001 Pontiac Bonneville SLE

Question type: Maintenance & Repair

I add coolant about every three weeks. It has never overheated and runs very well. I see where coolant has leaked from the upper manifold gasket and has run down the outside of the engine block. I want to stop the leak before it causes a real problem.

You can actually buy the same kit from your local parts store, it is the same one and it can save you a few dollars, I have used these in my shop for a long time and they seem to be better than the stock units, never had a comeback using these. HTH

At NAPA we sell kits made by Doorman. They're very good. I can't remember one ever coming back. HTH. -Jim
