    Starter won't crank when hot

    This has been discussed before, but I have discovered that my LS1 starter won't even "click" if it's hot and it has been sitting for over 15 minutes. Let it cool down and it's OK. I have heard this discussed before, but how are people fixing this? I'm planning on replacing the whole starter/solenoid but if the heat issue comes up again, what can be done? It's awfully close to the exhaust pipes and I suspect that's the problem. Exhaust wrap? Divert cooling air onto the starter? Any suggestions would be appreciated.

    To me it sounds like your starter/brushes are shot and it would be time for a rebuild or new one.. A lot of people's starters are close to their headers/exhaust without this problem.. Goodluck

    Is the starter original?

    Either way, if your going to replace it, I would try a to swap the starter relay out first, as these are likely to go bad with heat as well. Plus it's alot cheaper.

    I have already replaced the solenoid, and now I have put a completely new starter/solenoid from Powermaster on. Hope it does the trick. Thanks for the feedback.

    Pony up the extra money for a new starter. You will sometimes have problems with a remanufactured unit. The brushes are shot and unless you know how to rebuild one ( not that difficult ) You have to replace it. Good luck, let us know how it works out for you.
