Poor maintenance could be the reason why your Mazda is overheating every time you drive it. If you haven’t had your oil changed in a long time, it is no longer able to draw heat away from the engine. The problem could also lie in your cooling system. The coolant should be replaced every 30,000 miles. Mazcare can inspect your Mazda’s engine to see why it is overheating all the time.
Leaking Cooling System
Aside from dirty coolant, leaking coolant can also make the engine overheat. Anytime coolant leaks out of the cooling system or heater core, the levels get too low to keep the Mazda’s temperature below 220 degrees Fahrenheit, the recommended maximum temperature.
Clogged Cooling System
You may also end up with a clogged cooling system if you haven’t had the system flushed in 30,000 miles. Debris can build up inside the radiator hoses and radiator and cause problems with cooling circulation. If the coolant isn’t circulating, the Mazda will overheat.
Poor Coolant Circulation
One thing that can affect how well the coolant circulates through the engine is the water pump. If you drive a Mazda that has over 100,000 miles on it, it’s possible that the engine is overheating because the water pump is no longer circulating coolant through it.
Thermostat Malfunction
An old thermostat can also malfunction and fail to release the coolant into the engine. When this happens, your Mazda will overheat quickly after you start it. The thermostat lasts, on average, about 10 years. Older Mazdas may need new thermostats.
Cooling Fan Malfunction
Another thing that can make your engine overheat all the time is if the radiator cooling fan is malfunctioning. This fan helps to reduce the coolant temperature once it is returned to the radiator. The fan itself can die or you may have an electrical problem that has stopped it from working.
Damage to the Radiator
Finally, a damaged radiator will make your engine overheat all the time. Damage to the radiator can include corrosion that eats through the bottom, clogged air inlets, and dense caused by road debris. We may need to replace your Mazda’s radiator to prevent the engine from overheating.
