A problem in the cooling system is the most common reason why your car will overheat all the time. This being said, you may also have other engine problems causing the high temperatures such as old motor oil or an overheating fuel pump. Accurate Auto is going to list seven common reasons why your car overheats all the time due to a problem in the cooling system. Regardless of the cause, it’s important that you don’t drive an overheating automobile. If you continue to drive it, you run the risk of damaging the engine beyond repair.
1. Bad Cooling Fan
Engine coolant circulates through the engine to keep it cool. Once it’s hot, it’s returned to the radiator where a cooling fan and vents reduce its temperature. If the cooling fan has gone bad, you may have hot engine coolant circulating through the engine.
2. Bad Thermostat
Another problem that will cause your engine to overheat all the time is a bad thermostat. If the thermostat is malfunctioning, it’s not releasing coolant into the engine. It could be that it has failed completely or it is on its way out.
3. Bad Water Pump
A bad water pump can also cause your engine to overheat all the time. Once the thermostat releases the coolant, the water pump circulates it. If the water pump is unable to circulate the coolant, your engine isn’t getting any coolant at all.
4. Clogged Cooling System
Your engine may also not be getting any coolant because there is a clog in the cooling system. It could be that the radiator is clogged or one of the radiator hoses is clogged. If you don’t have your cooling system flushed on a regular basis, it may end up clogged.
5. Coolant Problems
Coolant problems can also cause your engine to overheat. It could be that you have the wrong coolant in the engine, that it’s diluted too much, that it is old and dirty, or that you don’t have enough coolant in the engine at all. This will definitely make your car overheat.
6. Radiator Damage
Radiator damage can also cause your engine to overheat all the time. As we said above, the radiator can clog and it can also become corroded with rust. Once corroded, the rust will eat through the bottom of the radiator and you’ll end up with a leak.
7. System Leak
The radiator is the only thing that can leak in your cooling system. The water pump can leak, the radiator hoses can leak, and the seals and gaskets can leak. If you have a cooling system leak, your engine is overheating because you don’t have enough coolant in it.
