The old engine had 140,000 miles on it. It overheated when the
driver--thats me--with his limited high frequency hearing--failed to
hear the high temperature alarm. This happened in Fairmont WVa on
the way to Flordia for the Daytona 500. It was 5 degrees outside.
Reason it happened was the fan switch failed, and, believe it or not,
the shop failed to replace it. When they changed the engine they
changed the bad switch over to the new engine. Then they ran the
coach on their chassis dyno with the fan over ride switch engauged
thereby omitting the only test-other than a test ride-that would have
picked up the bad switch situation. I test drove it and the
temperature went right up. Three hours later we had a new fan switch
and were on our way.
The old engine was traded in (core). They would have let me have it
if i wanted to pay the core charge but I chose to give it to them.
There were no cracks in the heads or block but both head gaskets were
gone. There were other problems inside the engine having to do with
bearing on some shaft-not the crank. That old engine with 140,000
miles on it was a 2 ring engine (the pistons had 2 rings). The new
one has 3 ring pistons and I think a little less power but it doesn't
blow vapors out the breather like the old one. Of course those
vapors ended up in my radiator as you are well aware.
