Car Overheating and Check Engine Light

Overview

When your car overheats, it’s a serious problem that needs to be addressed immediately. Overheating can cause major damage to your engine, and it can even be dangerous. If you see your temperature gauge climbing into the red, or if the check engine light comes on, pull over to a safe place and turn off the engine.

There are a number of things that can cause a car to overheat, including:

* **Coolant leaks:** Coolant is a fluid that helps to keep your engine cool. If there is a leak in the cooling system, the coolant will leak out and your engine will overheat.
* **Faulty water pump:** The water pump circulates coolant through the cooling system. If the water pump fails, the coolant will not be able to circulate and your engine will overheat.
* **Clogged radiator:** The radiator is a heat exchanger that helps to cool the coolant. If the radiator is clogged, the coolant will not be able to flow through it properly and your engine will overheat.
* **Faulty thermostat:** The thermostat regulates the flow of coolant through the cooling system. If the thermostat fails, the coolant may not be able to circulate properly and your engine will overheat.

Symptoms of Overheating

The following are some of the symptoms of overheating:

* **High temperature gauge reading:** If the temperature gauge is climbing into the red, it means that your engine is overheating.
* **Check engine light:** The check engine light may come on if your engine is overheating.
* **Steam from under the hood:** If you see steam coming from under the hood, it means that your engine is overheating.
* **Knocking noise:** If you hear a knocking noise coming from the engine, it may be a sign that your engine is overheating.

What to Do if Your Car Overheats

If your car overheats, the first thing you should do is pull over to a safe place and turn off the engine. Once the engine is off, you can pop the hood and check for any obvious problems, such as leaks or a broken water pump.

If you don’t see any obvious problems, you can try to restart the engine. If the engine starts and runs without overheating, you can continue driving. However, if the engine overheats again, you should stop driving and call for assistance.

Preventing Overheating

There are a few things you can do to help prevent your car from overheating, including:

* **Check the coolant level regularly:** The coolant level should be checked at least once a month. If the coolant level is low, add more coolant to the reservoir.
* **Flush the cooling system:** The cooling system should be flushed every two years or 30,000 miles. Flushing the cooling system will remove any debris or buildup that could clog the radiator or water pump.
* **Replace the thermostat:** The thermostat should be replaced every five years or 60,000 miles. Replacing the thermostat will help to ensure that the coolant is flowing properly through the cooling system.
* **Keep the radiator clean:** The radiator should be kept clean to prevent any debris or buildup from blocking the airflow. You can clean the radiator by spraying it with a hose or by using a radiator cleaner.
