6 Reasons Why Your Mazda Is Overheating

No Comments

Don’t let your Mazda overheat. At the first sign of trouble, stop by Mazcare so we can fix the problem. Your Mazda relies on the cooling system to keep the engine temperature below 220 degrees. If the temps get any higher than that, they can damage your engine. Here are six reasons why your Mazda is overheating that need to be addressed before you end up with serious engine damage.

Coolant Problems

The cooling system circulates coolant throughout your Mazda’s engine to keep it cool. If the coolant is low, the wrong type of coolant for your vehicle, or if your system is out of coolant your vehicle will overheat. Leaks in the cooling system cause low coolant as does evaporation over time. Check your coolant levels regularly to make sure you don’t have a coolant problem.

Rusted Radiator

One thing that leaks coolant out of the system is a rusted radiator. Made from metal, the radiator corrodes over the years, leaving rust on the bottom to eat through it. This is a common problem on classic and older automobiles that have a lot of years and miles under their belts. If you see orange fluid on your garage floor, it could be coolant with rust from the radiator in it.

Broken Radiator Fan

Coolant absorbs engine heat as it flows through the engine and then makes its way back to the radiator. The radiator stores the coolant to reduce its temperature, aided by the radiator fan that blows over it. If the fan malfunctions, it will not reduce the coolant’s temperature. The hot coolant will circulate through your engine again, keeping it hot, and eventually causing it to overheat.

Broken Thermostat

Your Mazda’s cooling system thermostat monitors the engine’s temperature and releases the coolant once the engine starts to get too hot. Sometimes, the thermostat will malfunction. It could be dirty and clogged or it could be at the end of its life. If the thermostat cannot release the coolant to reduce the engine’s temperature, you’ll end up on the side of the road overheated.

Heater Core

The heater core is actually part of your Mazda’s cooling system. It uses hot coolant to warm the cabin air before the coolant heads back into the radiator. The heater core can leak or get clogged and in either instance, your car will overheat. It’s a good idea to have the heater core checked every fall just to make sure it’ll keep you warm inside your Mazda in the winter.

Engine Oil

Finally, motor oil also keeps your Mazda’s engine cool. It reduces the friction between moving parts which, in turn, reduces the heat they produce. Depending on the recommendation for your Mazda year and model, plan to have the oil changed every 3,000 miles unless you use synthetic oil. The cleaner and more viscous the oil the less heat engine parts generate.
