Why Is My Car Running Too Hot?

If your engine is always running too hot, there’s something wrong with the cooling system most likely. Hummel’s Automotive Diagnostic & Repair can inspect your cooling system and if we don’t find a problem there, we will also check other culprits that include the exhaust system and your motor oil. It’s important to have the problem addressed right away; a hot engine becomes a damaged engine.

Clogged Radiator Vents

The radiator uses a fan and vents to help cool the hot engine coolant that is returned to it after circulating through the engine. Dirt and grime can clog the radiator vents and block cool air from flowing through them. This diminishes their ability to cool off the hot radiator coolant.

Cooling System Clog

Your cooling system can also be clogged by debris. If you have not been good about getting coolant changes and system flushes when the services need to be done, chances are you have more than coolant circulating through the system. You also likely have clogging dirt and debris.

Cooling System Leak

If your car has quite a bit of mileage, your cooling system can eventually begin to leak. The radiator hoses are a common cause of coolant leaks, as is the heater core, water pump, and system gaskets and seals. You may see the leak on your garage floor.

Incorrect Coolant

If you have the wrong coolant in your engine, your vehicle will overheat. It’s important to use the coolant that your automobile manufacturer recommends. Using a different coolant type can damage your cooling system and fail when it comes to keeping the engine temperature down.

Malfunctioning Radiator Fan

The radiator fan cools the engine coolant along with the radiator vents. If this fan is malfunctioning and does not turn on, as with the clogged radiator vents, you’ll end up with hot engine coolant circulating through the engine and this will make your car overheat.

Malfunctioning Thermostat

The thermostat is the part that keeps track of how hot your engine is getting and releases coolant when the time comes for it to circulate through the engine. If the thermostat is malfunctioning, it may never release engine coolant, which means you’re driving with zero coolant circulating through the engine.

Radiator Damage

Finally, your radiator itself can be the source of your cooling system problems. If it is clogged by years of sediment or leaking because it has rusted, your vehicle is losing precious coolant and the engine will run too hot every time you drive your car, truck, or utility vehicle
