Can a faulty coolant sensor cause an overheating car?
A coolant temperature sensor may not cause an overheating engine by itself, but if your car has an electric thermostat or water pump, it may trick them to not work properly. A faulty coolant temperature sensor may also trick you by thinking that your car is overheating but it’s actually not in reality.
How does a car coolant thermostat work?
This ensures that the coolant in your engine stays within a specific temperature range regardless of the outside temperature. The valve is opened and closed with a spring, piston or another thermally controlled device. Because they are so simple, thermostats generally do not go bad with age.

What causes a car to overheat with no coolant?
A common cause of car overheating is a low-cost thermostat stuck closed, restricting coolant flow. Low engine coolant level. An engine coolant leak internally or externally reduces the level in the system, preventing proper cooling. Blown head gasket.
What causes a car to overheat in the garage?
Some of those possible overheating causes apply to both situations and these are among the easiest repairs you can tackle in your own garage. By a large margin, the most common cause for engine overheating is simply a low coolant level. Your engine’s cooling system relies on coolant to circulate and remove heat from the engine.
What to do when your car overheats?
There are several ways to combat overheating in your vehicle. Have the cooling system flushed at the manufacturer’s recommended interval or when it is dirty. Have a technician repair coolant leaks as soon as they appear. Get your engine oil changed regularly.
Why is my car overheating in the winter?
Overheating occurs in winter due to a deficiency that occurs in a vehicle’s cooling system. Most common faults are coolant leaks or a blocked thermostat.

Why is your car overheating in the winter?
If your car is overheating in winter, it may be due to a lack of fluid in your antifreeze reservoir. This is a common yet, most easily ignored cause of overheating vehicles in winter.
What causes cars to overheat?
A faulty radiator can cause a car to overheat by preventing the adequate cooling of circulating engine coolant, which ultimately leads to an increase in engine operating temperatures and, in severe cases, engine overheating.
Will a bad thermostat make your car overheat?
Because your thermostat controls temperature of fluids from the radiator hose, a bad thermostat will cause your car to overheat. When the engine temperature has reached the operating level, it should allow coolant to flow to the engine and regulate the heat.
How long does it take to change a thermostat in your car?
The time required varies by vehicle year, make, and model. The required time could range from 1/2 hour to literally hours in some unusual designs. For your particular year, make and model, that is a 2002 Protege, it requires about 1 hour to remove and replace the thermostat.
How does a car act with a bad thermostat?
A bad thermostat can cause the car to swelter , as the thermostat is a heat-sensitive control device situated at the radiator hose. When the temperature of the engine reaches its normal operating temperature, this device should open to allow coolant to flow into the engine to regulate the heat.
Why does my car overheat when the water pump is not working?
A water pump that is not working properly can lead to overheating because the hot coolant is not being pumped out of the engine and replaced with the cooler fluid that is exiting the radiator.
