Car will Cold Start, after getting hot it will not start until it cools off.

It sounds like you have vapour lock.

What is fuel system vapor lock

bad starter.

What fuel are you using?

If you mean that it starts fine when cold, but if you stop & turn off the engine (to to pop into a shop for example) then try to restart and get absolutely no turning over, then you need to replace your battery. It has a short or crack which is expanding when hot creating your problem.

Sounds like you might have a faulty ignition switch and ignition lock cylinder.These cars are known for the ignition switches getting hot and then they won't start.

In a lot of cases, this is an indication that the starter is faulty. A bad starter will often start a car when it's cold (ie first thing in the morning or after sitting a few hours). Once hot, the starter requires more and more energy to turn over. If when hot, you are able to start the car with a jump start, the starter would be the first place to investigate.

you still have air trapped in the cooling system. Get front of car as high up as you can on a hill. Cold engine - loosen radiator cap, fill with 50/50 antifreeze mix. Start engine and run until upper radiator hose is hot (thermostat open). Engine should burp air and maybe spill some coolant, that's ok. Once burped, tighten cap, shut off engine and let it cool down while keeping the reservoir full. It will **** coolant out of reservoir as it cools. Keep it full.

If still cold air, take to a shop that has evac/fill equipment; they will **** air out and repalce with coolant. About $80.

gerry

It could be the electric fan is going on too easily.
The radiator and hoses should be almost too hot to touch.
And when cold, the fan should not really do on at all.
But the thermostat could be opening too soon also.
There are two hoses to the radiator, and when you start a cold car, only one should slowly get hot.
The other should stay cold until the thermostat opens, after the engine is good and hot.
If both start slowly getting warm at the same time, then you need a new thermostat.
And also make sure you have enough coolant in the radiator.

The car is having overheating problem,its not battery(change top gasket)

I had the same problem a few years ago. The problem was a cracked coil. The unit would expand and separate when the car got hot and it took a while to cool off and reconnect.
