I have a stock '75 coupe that will not re-start after the motor heats up and is driven a while. I'm thinking the starter/coil are heating up and has to cool down before re-starting. I don't think the problem is in the ignition switch. Sometimes it takes 45 minutes or so just sitting and waiting. Not quite as long if I open the hood completely and let the heat escape. I'm getting nothing but silence when I turn the key, like a completely dead battery. It's not like it's turning over but not starting. Once it cools down, it starts OK, no problem.

I purchased a GM starter heat shield but don't know exactly how to install it. I didn't know until recently that it was even available. I had heard of other folks who manufactured their own. Need some help or a photo of exactly where it bolts on.

Thanks.

 

I doubt that the heat shield will correct your problem with the solenoid thats on the car presently.I would suggest that you replace the solenoid and then add the heat shield.

 

Here's a pic of the original, if that's any help

 

I don't mean to thread hijack, but I have KINDA a similar problem.


I have a chrome heat shield for the distributer, which came with the car. But the distributer is no longer stock, and I can't for the life of me get that darn heat shield back on. I have been running it without it for a while now, with no problems. How important is that thing, or is it just dress up?

 

I have a JC Whitney heat shield for my starter that i really like. U can see the pix in my signature link (pix #2 & #3). It took a little modding but not alot. Just make shure u leave an airgap everywhere but where the bracket bolts to starter. I tried several shields but this from JC Whitney did the trick (part #ZX830176Y) - worked great in >100*F temps.

Hope this helps,

It's not a heat shield. It's there to keep the electronic "noise" from the distributor from interfering with your radio reception. You don't really need it, just may get interference on your radio without it.

 

I had the same thing happen to me. I put one of these on:

Nice short link eh? Anyway, they had it down at my local Schuck's Auto. I put it on (much easier with the starter OUT!!) & it helped for a while, until I had to start smacking the starter with a hammer to get it to turn over .

I finally replaced the starter, but I put this little shield on the new one too, figured it couldn't hurt. I also have the stock thing too.

I liked this better than a wrap, since I figured that wrap would hold heat in, and take longer to recover if it did heat soak again.

Just my story. Good luck!

 

i'm running the original 35 year old GM starter with headers , gets stinking hot in the engine compartment and it still spins the motor up no problem...I threw a set of brushes and bushings in when I did my rebuild.
Make sure to check all your cables and ensure you have good grounds.

 

and make sure your using a heavy duty Delco, not a light duty.
I tell people to check the ground to the frame from the battery, very important. .

 

I like that solenoid shield danno. Looks good as long as there's an air gap maintained from the metal surface on the solenoid.
And i agree as i think those heat wraps just hold the heat in once the starter gets hot.

Kalaway, dud you find a fix that worked. I was hoping to find a chrome starter shield, still looking. Any suggestions?

 

Bill, this thread is from 2008. Maybe put an ad in the WTB section.

 

Yes sir, when I read it I thought you might have found a good fix. Thanks
