When we get in the car for our commute or an errand, we expect it to work properly without problems. There are times when your engine will overheat, which will cause major issues and affect your ability to get from point A to point B. It could even leave you stranded on the side of the road, waiting for a tow truck.
If your car is overheating, you will be notified by your dashboard gauges. Your engine temperature light may illuminate or move into the red zone to notify you there is a problem. You may also see the tell-tale white steam rising from under the hood of your Volkswagen.
If you see any of these signs, you will want to stop driving immediately, pull off the road somewhere safe, turn on your hazards, and have your car towed to your trusted technician for a diagnosis and repair of the problem.
It is always a good idea to go to your mechanic with as much information as possible, so we suggest that you have an idea of the possible causes of this problem. For instance, you may have seen fluid underneath your car, so you suspect a leak. You will be able to let your repair shop know this valuable information so they can start there.
You will also want to tell them any other signs or symptoms you may have noticed, as there may be more than one thing going on in your car. It is also essential to let them know a timeline, such as if this is the first time you’ve experienced this issue or if there is something you have noticed for some time but haven’t had a chance to explore.
6 Causes of an Overheating Engine
Below are six primary causes of an overheating engine in your Volkswagen.
- Low coolant levels: One of the most common problems is that your coolant is low. As long as it has become low over time and use, this is easy to fix. However, when your car is starting to run hotter than usual due to a leak or malfunction, you should bring it into a mechanic right away to prevent high engine temperatures, which will cripple your Volkswagen’s ability to run. Check your coolant level. If it is under the manufacturer’s suggested fill level, top it off to the fill line but not above it.
- Low oil levels: If your oil is lower than it should be, your car may also overheat. This occurs because the oil lubricates the engine and it absorbs heat. Overheating is only one problem you may face with low oil. If your oil gets low enough, you can seriously damage your engine and even destroy it. This will cause metal to rub harshly against metal, shredding it and leaving shards in its wake. So always make sure your oil level is correct.
- Leaking hoses or reservoir: Sometimes your low level of coolant is because you have some leak in the hose or the reservoir This will need to be replaced by your mechanic, and if it is the only issue, your car will stop overheating.
- Faulty thermostat: Overheating can be caused by a faulty thermostat. If your thermostat is not working correctly, your car will not know when the heat is rising, which will be problematic. When your engine begins to heat up, the thermostat detects this. The valve is opened to allow the coolant to circulate. If the thermostat is not working correctly, nothing will be done to regulate the engine’s heat.
- Broken water pump: Another issue that could cause your Volkswagen’s engine to overheat is when the water pump is failing or already broken. The water pump propels the coolant forward throughout the entire cooling system.
- Radiator issues: A final potential cause of your car overheating is problems with the radiator or the radiator fan. For instance, if there are any clogs or leaks in the radiator system, heat will not be able to properly escape your vehicle. This will cause the engine temperature to rise, and the result will be an overheating engine in your Volkswagen.
