Engines overheat when the cooling system fails to function properly, causing trapped heat. Causes may include a coolant leak, faulty radiator fan, water pump malfunction, low engine oil, or a broken thermostat. Ignoring an overheating engine can lead to severe and potentially permanent engine damage.
Engines usually show signs before overheating. Here are four of the signs:
Right away, switch off the air conditioner to ease the pressure on the engine. Then, set the dial to the hottest setting. This can draw heat away from the engine, preventing it from overheating until you can stop in a safe place. You might feel a bit warm, but enduring a few minutes of discomfort is much better than facing costly engine repairs.
Stop the car and turn off the engine. Let it cool down for at least 15 minutes. Watch the temperature gauge; it should go back to normal as the engine cools. While waiting and monitoring the gauge, make a plan to have your overheated engine inspected.
If your car overheats, it might be because of a coolant leak. After pulling over safely, check your coolant levels. If they’re low and you have extra coolant, add some to help temporarily until you can solve the main problem. However, if the overheating is due to a hose or radiator issue, adding coolant won’t solve the problem.
If your car isn’t being towed, it’s safe to restart the engine cautiously and head to the nearest auto repair shop. While driving, monitor the temperature gauge. If it starts rising again, pull over and allow the system to cool down.
If you look after your car, it will look after you. To avoid an overheating engine, make sure to get regular check-ups and coolant changes for your car. Keep up with radiator maintenance as advised by your vehicle’s manufacturer. Regular inspections can also help identify and fix potential radiator or engine problems before they become serious.
