HOW TO STOP AN ENGINE FROM OVERHEATING
Pull over and open the hood to allow heat to disperse faster.
Do not open your radiator pressure cap (the cap on top of the radiator) while the engine is hot.
Check the coolant reservoir tank (plastic on top of radiator) and fill with coolant or water if needed. If your car has a radiator and no coolant reservoir, you must wait for it to cool
before checking the level of the coolant. Check the owner’s manual or wait for the car to cool before opening.
Look for a leak in the cooling system. If your radiator or cylinder head seem to be compromised, or if you open the coolant reservoir and the levels are topped up, call for help.
Determine whether to drive on or call for help. If the car was simply low on coolant and you were able to refill it, it may be safe to drive on.
