Why is my car overheating and my heater not working?
The heater not working in some cases may be related to the overheating problem you are also having. This may be due to a faulty heater blower motor or potentially a bad heater core. Engine overheating can be caused by a number of things such as low coolant levels, a faulty thermostat, or a failing coolant fan switch.
Can a clogged heater core cause overheating?
Engine Overheating Even a clogged heater core has the potential to obstruct coolant flow enough to cause overheating. A low coolant level (caused by a leaking heater core) can lead to overheating and possible engine damage.
What to do if your Toyota Corolla heater is not working?
If your Corolla has a built in temperature gauge, take a look at it and see if it is in the spot it is normally in after a bit of driving. If it looks like it is colder than normal, that’s a pretty good indication that there is something wrong with the thermostat. The heater core itself can go bad.
What does the thermostat on a Toyota Corolla do?
Never touch the radiator cap unless the vehicle is ICE COLD. The job of your Corolla’s thermostat is to regulate the temperature of the engine. It does this by allowing water to enter the engine when it is getting hot, and by keeping coolant from entering while the vehicle warms up.
Why is my Chevy Impala heater not working?
If you have a heater core that clogged, it’s not going to be able to pass coolant through. Without the warm coolant going through it, there can be no heat. A bad heater core can also leak, so watch out for that. Feel your passenger floorboard to see if it’s wet. Heater core’s are typically pretty affordable.
What happens if your car radiator is too hot?
If the engine is too hot, the thermostat will open to allow the flow of coolant into the radiator. The radiator will then cool it down before it is pumped back through the engine block by the water pump.
