My 03 200 BR (5.0 MPI - Alpha G2) was leaking drive lube and the dealer determined the leak was at the impeller housing, which was limiting the amount of water being pumped to the engine. They said, based on this, it should have been running hot. It always indicated 175 or so on the water temperature gauge, which I was told was normal. Now I'm wondering if there was enough water being circulated to even register the temperature.
The exhaust flappers were melted, so it got at least hot enough to do that, but I never got an alarm of any sort, and the engine ran fine. I just had to keep filling the drive lube reservoir. I ran it enough that, if the engine was being damaged, I think there would have been symptoms. Oil pressure was always good, I never heard anything out of the ordinary, and the exhaust manifolds were only slightly hotter than touchable.
I asked them to run a compression test to determine if the engine got hot enough cause damage and the manager told me they got 115-120 psi on all 8 cylinders. I've ran compression tests before on Chevy v8's and always got in the 140-150 range. The engine has 43 hours on it, so it should still be fairly fresh. Do those numbers look right?
