What to Do When Your Car Overheats
An overheating car can be frustrating, time consuming and costly depending on the cause.
Every one of us has experienced the frustration of car overheating. You are driving down the road and all of a sudden, the gauge starts to rise and the little poof of white steam escapes from under the hood. Car overheating is one of today’s common problems faced by drivers.
There are a number of car overheating symptoms that if heeded, could prevent overheating before the actual car overheating starts. If the problem is not fixed during the symptoms phase, it can cost you both time and money to repair your vehicle.
What causes a car to overheat?
There are many reasons for car overheating. Being aware of them as a driver empowers you to control situations before they get worse. So here, we discuss a few of the car overheating causes.
1. Thermostat- A stuck thermostat is probably one of the most common car overheating causes. When the thermostat is stuck, it blocks the coolant flow to the engine. This results in the car overheating.
2. Cooling System- A car also overheats when there is a leak in the cooling system of your car. Due to this leak, some of the coolant is wasted and there is no sufficient amount to cool down the car. This eventually leads to the car overheating.
3. Water Pipe- The coolant is circulated in the car engine with the help of a water pipe. If there is a fault in the water pipe, the coolant is not available to cool down the engine. Hence, the engine and eventually the car overheat.
4. Fans- There are two fans in the car which control the temperature of the engine. One of them is mechanical while the other is electrical. The mechanical fan adjusts its speed depending upon the temperature of the engine. Thus, it maintains the temperature of the car. The electrical fan starts when the temperature of the engine reaches the operating temperature or when the car’s engine is under pressure of the car A/C. If either of the fans have some flaw, then the engine temperature cannot be controlled leading to the car overheating.
5. Radiator- If the radiator is clogged with dust and other debris, empty or leaking it could cause car overheating.
How to repair a car that overheats
To avoid all the needless visits to mechanics regarding the overheating of your car, you could follow these guidelines to find the problem and repair it.
- Check if the car engine is overheating or not. This is the most trivial reason of car overheating. Sometimes there is a problem in the temperature sensor of the car and hence we cannot detect the problem.
- Check the fan that cools down the car engine to see if it is working properly or not. Check all the electrical system of the fan if it is in good shape. The basic test is to let the engine heat above normal temperature and check if the cooling fan is doing its job or not.
- Check the hoses, a common car overheating cause is leaks in the hoses. Therefore, you need to switch on the engine and search for the leaks. If the gasket shoots out smoke or steam then it is an internal leak. Otherwise, you find it hard to start the car. There are various other causes for lack of coolant in the engine as discussed above. Check for all of them and repair the problem
