If you ever saw the temperature gauge is all the way up to the “H” while driving your car, it means that your car is about to overheat. Each time your car overheats, it causes damage to the engine and the costs to repair overheating damages are very expensive. Here are a few tips on how to avoid overheating:
Check your Antifreeze. If your car is not circulating antifreeze properly, it may cause the engine to overheat. Antifreeze keeps the engine temperature at a desired level for your engine: both during summer and cold winter (preventing the water to freeze). Always check underneath your car while it’s parked and see if you notice any leaks in puddles or just simply look for stains while your car has been parked for several hours. It might just be your antifreeze leaking, which will cause a lower level circulation to the engine, thus, causing overheating.
Sometimes, though, you may not notice an antifreeze leak by looking underneath the car. Therefore, it’s always a good idea to regularly check antifreeze levels, making sure it’s at a proper level stated by your owner’s manual.
If you have ever found yourself in a situation, where your car is about to overheat (that’s when your temperature gauge nears a high,) immediately turn up the heater. Running the heater will cool down the engine temporarily and the temperature gauge should drop slightly, or may even return to a normal level. Safely park your car and turn it off. You can also open the hood to have the air cool the engine, but NEVER open the radiator pressure cap at any circumstance, while the engine is hot. The hot radiator fluid will cause severe burns.
You may also add some water to the antifreeze tank, if you know where it is located. This will also cool the engine by circulating cool water through it.
If you ever choose to run the car while the temperature gauge is on a high level, be prepared for some costly repairs cause by the overheating damage. Turn off your air-conditioning, as it adds more pressure to your engine. However, you might have to tow your car to your nearest auto repair shop to have it looked ASAP, at after driving it for a long time while the temperature gauge is on high.
