What to Do When Your Engine Overheats

1. Kill the A/C and crank the heat. Immediately turn off the air conditioner to reduce stress on the engine.
2. Find a safe place to pull over. Pull over and shut off the car.
3. Check and add coolant (if you have it).
4. Restart the engine.

How do you start my car after it overheats?

If your engine is overheating, do the following to cool it down:

1. Turn off the air conditioner. Running the A/C puts a heavy load on your engine.
2. Turn on the heater. This blows some excess heat from the engine into the car.
3. Put your car in neutral or park and then rev the engine.
4. Pull over and open the hood.

Can coolant cause a car not to start?

Running out of coolant/antifreeze won’t necessarily cause instant damage though, depending on your car. This uses the cooling system’s thermostat to kill power to the engine when the temperature reaches a certain point, and means that the car can’t be restarted until it has cooled down sufficiently.

Can overheated car not start?

Overheating can warp the cylinder head and/or engine block, which can cause a failure to start due to loss of compression, valve damage and so forth. Certain engine faults, such as a leaking head gasket or poor engine running condition can also cause overheating.

Why is my car not starting after overheating?

There is a good chance that you have a blown head gasket and is not letting the engine build up compression, or you have water in a cylinder. Pull the engine oil dipstick and see if it looks like chocolate milk, if it does the the head gasket is blown.

I got home, and when I went to replace the thermostat, the car won’t start. Hello, when you say the car won’t start, is it a crank no start or does it not even turn over?

If the thermostat is damaged, and left in place, that can set the stage for future cooling system problems. In your circumstance, you appear to have the additional problem that the car won’t start but that will be diagnosed and resolved after the mechanic restores the cooling system.

Why does my car not start on H20?

My theory as to why it won’t start is because there’s water in the cylinders (from the blown head gasket) and as we know, a gasoline engine doesn’t run or start well on H20. Wish they did though. A bad water pump shouldn’t effect your timing.

What to do if your car engine wont start?

If you can’t get ahold of one and the engine still cranks (but won’t fire), pull one plug at a time, when it’s out, have someone turn the ignition key and crank the engine. Make sure you still have water in the radiator.
