Perhaps someone can help me.
I finally completed the install of a Moyer rebuilt A4. Ran nicely today but it over heated. Why?
This is a fresh water cooled engine so I'm looking at two systems.
There is strong flow of water from the exhaust so the raw water side seems ok.
I suspected that perhaps the impeller pump of the fresh water system was not working (I just rebuilt this pump) but the water coming out of the exhaust is warm so heat exchange seems to be happening.
Could be the heat exchanger but if the salt water side is not restricted I think the fresh water side should be OK.
Maybe the temperature gauge or sender is the culprit but I get readings starting at 0 and increasing to about 210 degrees. I think that if the sender or gauge were the problem I would get no reading.
What am I missing? Any suggestions will be greatly appreciated.
Thanks,
Dave.
PS I forgot to mention that the coolant water in the overflow tank did not rise above the "cool" line when the engine temperature reading was high.
