Stops running in hot weather then runs after it cools down

Well of course not. When you shut the car down, all water circulation stops so engine heat goes way up. This means the radiator gets hot too, and therefore so does the AC condensor. It takes time for all these things to cool back down when you start it back up.

This sounds like it's your radiator fan or engine bay fan continuing to run due to the hotter weather we are having. Some fans are programmed to cool the engine bay area if their thermostat triggers them. These conditions usually happen when weather becomes very hot and triggers the system to continue the fan due to excessive heat in the engine compartment. Usually not a bad thing and should stop when weather cools down. What is worse is if the fan doesn't work. Keep an eye on it and see if it continues to do this when weather cools down.

Sables always have radiator problems also ive owned 2 and first thing ive done when bought them is replaced the radiator and added an external cooling system

Your AC system is supposed to shut down if the engine is hot, as a safety device-make sure when the ac is running , the radiator fan is blowing-it may not be, caused by either a bad relay, blown fuse or a bad fan motor. Make sure your antifreeze is fully up to level, and if you haven't done it in the past 2 or 3 years, get the cooling system serviced with a new thermostat-cheap insurance, you do NOT want to overheat that aluminum engine, because if you do, it will be toast.

bad ignition modual , and when it cools off it'll start again ! use a napa modual

check engine coolant temp sensor, its detect engine overheats that command the computer to engine shutdown for protection, try to replace a good one

Sounds like the coil has gone bad. This is usually the syptoms of this. When it is in the non crand status cool the coil down quickly with ice and see if it doesnt crank.

Hello,

I would also be compelled to suspect the lack of Fuel, towards from the Engine, normally the Carburetor combines fuel and air, into a highly volatile mixture. So when its hot, I would think it evaporates so quickly before it reaches the engine. Try to tighten any pipes, or look for leaks around the Carburetor.

For starters have the radiator and coolant system flushed which may help cool the engine better. But when it gets too hot, motor oil loses it's viscosity ( thickness and lubrication properties ) and gets thinner. Especially in hot weather you should make sure you have good oil and make sure you dont run it low on oil. On the flip side make sure that it's not overfilled because this will blow out the seals and you'll have much bigger problems than no power. Hope it helps!

have the starter tested because it sounds like a bad solenoid in the starter and it makes it get hot so it won't start
