Why is my car overheating but the coolant is full?
However, if your car is overheating, but the coolant is full, it is probably not a leak. Instead, it may be that it’s having trouble circulating correctly. This can stem from several things, including a faulty water pump, a radiator blockage, a stuck thermostat, or a plugged heater core.
Why is my car overheating with no leaks?
If there’s no leak, an overheat is caused by a problem with coolant level, coolant circulation, or heat transfer. Fill the coolant level. If the problem recurs within a month, it was something other than low level. Circulation problems are caused by clogged radiators, bad water pumps, non-functioning thermostats.
How do I fix my car from overheating?
What to Do When Your Engine Overheats

- Find a safe place to pull over. Pull over and shut off the car.
- Check and add coolant (if you have it).
- Restart the engine.
What do I do if my car is overheating?
Pull over to a safe location and turn off the engine. Do not open the hood until the car has completely cooled or the temperature gauge has moved from hot to cool. Check the coolant (also called antifreeze) level in the radiator. Look in the owner’s manual if you are unsure where the coolant reservoir tank is.
How can you tell if your car is overheating?
One of the most common reasons for a vehicle overheating is a stuck thermostat. It can stick or freeze in the closed position blocking the flow of coolant to your engine. The easiest way to check if your thermostat is not open is to feel the upper radiator hose. Once the engine warms up it should become warm.
What causes my car to keep overheating?
10 COMMON REASONS FOR OVERHEATING CAR PROBLEMS TOO LOW OR TOO HIGH LEVEL OF ENGINE COOLANT. This is the most common reason for overheating. COOLANT HOSE LEAKS. Another very common mishap that causes engine overheating. LOOSE HOSE CLAMPS. BROKEN THERMOSTAT. THERMAL SWITCH ON THE RADIATOR. BROKEN WATER PUMP. CLOGGED OR CRACKED CAR RADIATOR. CLOG IN THE COOLANT SYSTEM. CRACKED OR DAMAGED HEATER CORE.
Is my car really overheating?
If you are driving a car that is overheating but still has coolant, as in the case of having a faulty thermostat, the high temperatures can cause the antifreeze to boil, expand, and cause intense pressure within the radiator hoses. This can potentially result in hoses suddenly bursting or spraying hot coolant from a weak or broken seal.
