Engine overheats starter
Question:
John is right. I’ve encountered this before also. One or more brushes are stuck in their holder, losing contact as the starter warms. Eventually it won’t work at all.
Response:
The weak point heat wise is usually the solenoid. A number of Japanese cars (Toyota I think) had a heat shield that just clips on to the solenoid like a bicycle clamp. It will fit the G.M. starter. The shield does not have to be much. It reduces radiant heat loss to the starter and solenoid from the engine. It is usually more problem to attach then to make. Hose clamps are always a good bet. This problem is very common in street rods and some fellows have used a Ford solenoid on the fender wall to aid starting but I am not sure how they wire it up. Maybe a post to alt.autos.rod-n-custom will help? Other wild ideas are maybe the battery is weak. They do not much like heat either. You could be losing some amps that way. Upgrading the battery cable to a larger size could help too. – Hide quoted text — Show quoted text -> Probable cause, the brushes were going and would expand out to the outer > housing in the starter when hot, preventing them from turning.

no prob, it seems like an age/wear and tear thing. A friend of mine had suggested that and had seen it before. js

Thanks for the suggestion. Someone else suggested a heat shield but I had never heard of one and wondered about it’s effectiveness. > When was the last time you replaced the starter?
Someone locally told me that wouldn’t solve the problem as the new heater would also overheat, but your comment on the brushes makes me think it could indeed be an issue because the problem has slowly gotten worse. Thanks again.

Why don’t you go down to your local parts store and buy a heat shield for your stater it should solve your problem – Hide quoted text — Show quoted text – > I have an 86 Jimmy GMC that has a starter motor that gets hot on long > drives and requires almost a half hour to cool off be for it will start > again.

I had the same problem with my 4.3L S-10, it was about two summers ago (in the dead of Phoenix heat). Anyway, my starter would not turn after driving. The time I drove before I would shut down and then not start right aftewards seemed to get shorter in the few weeks I had the problem. It sucked, I’d get stuck at gas stations and wherever, took forever for the starter to cool down enough in that heat before it would turn over. Probable cause, the brushes were going and would expand out to the outer housing in the starter when hot, preventing them from turning. This is the theory anyway, it required a new starter, although at the time I didn’t think that was the problem. As soon as I put the new starter in, the problem was gone. When was the last time you replaced the starter? js

I have an 86 Jimmy GMC that has a starter motor that gets hot on long drives and requires almost a half hour to cool off be for it will start again. This is both a major inconvenience a potential safety hazard. Any ideas on how to deal with it?
