My exhaust pipe runs right next to my starter, so hot starting problems are nothing new. I usually would have to wait for the temp. gauge to drop below 180 after it had been running awhile. I recently replaced my OE style Delco starter with another one. This new starter seems to spin over better than the old one, but now after running the car at normal operating temp. for awhile, I have to let the car completely cool down to start on its own, or get a jump start. I was at a cruise in recently with the temp gauge well under 150, but still nothing. A jump start spun it over. Any ideas? Thanks.
