Why Is My Car Still Overheating With a New Thermostat?
A few days ago I noticed that my car’s temperature was running high. I was told that the overheating was probably caused by a lack of coolant or a bad thermostat. I’ve made sure the coolant is full and replaced the thermostat, but it’s still overheating!! Why would it still be overheating even with a new thermostat and what can I do about it?
Answer provided by
- Bad coolant: If the coolant is failing, faulty, contaminated, or just the wrong kind for your engine, it would cause overheating even when topped off.
- Bad water pump or belt: the water pump and belt work together to circulate water from the radiator. If one or both of them is damaged, it would cause overheating
- Broken radiator: All coolant in the world won’t keep your engine from overheating if the radiator is broken
- A clog in the coolant system: If there is a blockage anywhere in the coolant system, it will stop the fluid from circulating properly which could lead to overheating
- A faulty head gasket: This is a more serious issue that could affect virtually every aspect of your engine’s functionality
- Improperly installed thermostat: If you installed the new thermostat yourself, and haven’t done it before, you may have installed it improperly
