Why does the car temperature gauge go up?

With the development of technology, car overheating has become an old issue. However, that didn’t rule out the possibility of your car breaking down in the middle of the road. Many of the car owners face problems with their car’s temperature gauge. In most cases, the temperature gauge suddenly goes up. If you have faced this issue and want to know why it happens, you are in the right place. In this post, we will tell you everything you need to know.

Reasons Your Car Temperature Gauge Go Up

There is not one but multiple reasons why this happens. One thing you should know that this could cost you a lot of money to fix it. When your car gets overheated, the temperature gauge is the first thing to indicate it. If the gauge crosses the optimal mark, you should immediately pay attention to it.

1. Low coolant level

If your car has a low coolant level, it will cause it to overheat. This is perhaps one of the most common causes that spike the temperature gauge. In case, you didn’t know the coolant agent helps in reducing the heat from your car engine. This is why you should fill your coolant reserve, as soon as it gets empty. The same problem can arise if you have a leaking coolant reserve in your car.

2. Water pump malfunctioning

The water pump is one of the most important parts of a car. The main purpose of the water pump is to propel the coolant throughout the entire cooling system.  But over time, the water pump can give you issues. If you have a faulty water pump, it won’t be able to maintain the flow of the coolant. This can spike the temperature gauge of your car.  Some of the main causes that lead to a faulty water pump include shaft breakage, seal leakage, and casting breakage.

3. Radiator fan not working

Another cause of the temperature gauge rising could be a faulty radiator fan. The main function of a radiator fan is to draw cool air into the radiator when you are driving the car slowly.  If you see your temperature gauge rising, you should once check the radiator fan of your car. It can be found under the hood. Along with that also check the AC unit of your vehicle and turn it on. If it fails to work, then you know that you have a faulty radiator fan. In this case, you would want to take your car to a mechanic and get it checked.

4. Head gasket not working

This is one of the worst causes of an increasing temperature gauge. Those who have an idea about car parts would know how important a head gasket is for the engine. It forms a seal between the cylinder head and engine block. It seals the coolant, combustion chamber, and engine oil pass. If you have a damaged head gasket, it can lead to serious issues in your car.

These are four of the main reasons that could cause the temperature gauge of your car to go all the way up. In such situations, you should take note of the issue and take your vehicle to an auto mechanic. Ignoring such an issue could lead to serious problems in your car later. If you don’t want to spend huge bucks on car repair, then you should pay attention to the rising temperature gauge immediately. As a car owner, you should never ignore a rising temperature gauge. This indicates that your car is overheating due to some severe issue.
