Long time answerer (is that a word?) of questions, so I figure I am due.
I have a 1987 Ford E-150 with 160K - used to haul the racecar. It’s had a lot of issues and the latest is that when the engine has warmed up, then shut down, the starter struggles to turn the engine over until the engine cools Once it does, it turns over and starts right up.
I figure it’s the starter getting hot, but I want to know why this would be the case. Does the heat expand the starter shaft so it binds a bit with the bearing? Is it the increased resistance of the wire?
All thoughts appreciated.
