Hot start issue
I am having a hot start issue with the car. Just curious if this is a common design issue or problem with the starter. I see there are shield plates that can be installed starter shield wraps ect. The car is new to me and i am a first time corvette owner so i was looking for some basic education.
Also, is there a search feature that lets me limit searches to C3's section of the forum?
Thanks in advance

Hi,
'Hot start' issues - slow cranking, etc - are common with early corvettes (and Chevy in general). Old starter and old battery don't help things!! If your battery is good and the starter is good, then there are lots of 'fixes' out there like shields, wraps for the starter. I've found the 'remote solenoid' kit usually cures the problem. Uses a separate solenoid, similar to a Ford (!) mounted on the firewall to get away from the heat down by the starter. Cheap, easy to install. Checking timing probably wouldn't hurt. Too much makes it turn over slow also.
In the C3 thread listing page (or on any page), go to the top and use the "Search This Forum" feature. Will search the forum you are in.
Good luck.

Hi EC3,
There can be various causes for the 'hot start' situation.
I think I'd begin by taking a look to see if the starter/solenoid heat shield is in place.
Some folks find them a nuisance to install and leave them off.
Maybe?

It's black metal and wraps around the front and forward side of the solenoid.
I'd also check to make sure the spark plug heat shield for the 2 plugs above the starter is in place. It offers some protection from the exhaust manifold above the solenoid too.

I was just looking at ordering that. It is missing. Also i think the battery is 10 years old so i will need to get one of those.
My battery now is a top post. Should I convert it back to a side post?
Do you have any specific battery suggestions or brands? I was just going to go to pep boys or firestone and pick up what ever the book called for?
Oh yeah...there is no shielding anywhere that is all getting ordered

Hi EC3
You need to check to see what the ends of the positive and negative battery cables in the battery compartment are… are they of the type used with a side terminal battery? Are they still the original style?
You can then select the proper sized battery of your choice.
The floor in my garage (which is actually in the basement of our house) is laminate.
My restoration days are long past and this floor is easy for me to take care of.
I realize this flooring option is suitable for VERY few people… maybe even NO ONE else.

Are you getting to know your new car? Are you still pretty excited about it?

Common problem with no shortage of suggested solutions. If you want to eliminate the problem and never worry about it again, and assuming originality is not important to you, get a gear reduction mini starter off a newer vehicle, or from the aftermarket. I had the same heat soak hard start when hot problem off and on for years until I put on the gear reduction starter. Never had a problem since.

Having all the shielding is a good....BUT...that does not matter IF the bushings in the starter are worn. These bushings keep the armature true to the housing and field coils. The you also have the brushes that wear.
So when the starter is COLD..it works great...but when hot it acts up....and this also can be attributed to the wiring that is attached to the solenoid. I have experienced NUMEROUS solenoids where the positive battery cable that is attached to the big stud...the wire was tight on it...but when you loosen the nut holding the positive battery cable.,..you can feel that the stud is actually loose...and THAT is a BIG deal.. I have found in most cases that if I tighten up the jamb nut for the stud..and attach the positive battery cable...all is good.
AS for top post versus side post. I am NOT fan of any of the replacement ends for battery cables that only allows you to lock them in place with bolts and straps that hold the cable wire to the end. I PREFER sealed cable ends....but that is just me.

much misunderstood issue and often caused by other things, but if you are convinced it is the starter/solenoid, here is the bulletin.
next time it happens, spray some water on the starter to cool it off with the motor still hot and see if you still have the issue. I bet you do.
