A VW Passat is a spacious family car from Volkswagen. The first ever model of the VW Passat was presented to the market in 1973. Since then, 5 more generations of the said vehicle was released.
If you are driving a WV Passat and notice that you often experience overheating of the engine, you may need to consider checking the vehicle’s cooling system. The cooling system layout may vary depending on the model year, but the concept and parts remain the same. You can troubleshoot your VW Passat yourself or have a mechanic help you investigate the problem.
Below are some common items to consider when inspecting the cooling system of a VW Passat.
- Prepare your vehicle for inspection. In case you experience overheat while on the road, move your vehicle on the side of the street, away from other motorists. Park the vehicle and turn the engine off. As the engine is extremely hot, refrain from coming near it or holding anything near the engine. Allow for some time for it to cool down.
- Look for leaks. Take a look underneath the car to see if it has leaks. This can be caused by a worn out or faulty water pump that is responsible for keeping the coolant circulate. The water pump replacement can be purchased in any nearby car parts stores. Replace it as soon as possible to refrain from experiencing overheat.
- Check the hose. Open the car hood and locate the hose between the engine and radiator. Check if they have any holes or cracks. Also check the other hoses connected to the radiator. The leak may also be caused by damaged hoses. The antifreeze will continue to spill if you do not replace the hose immediately. And because you may be experiencing the leak for some time now, you need to check the coolant tank if you still have enough coolant left. If you are already running low, you have to do a refill. There are several coolant brands in the market. Choose the one with the longest antifreeze life. But remember to address the leak problem first, or else, you are only wasting the antifreeze.
- Clean the radiator. As you drive your vehicle, dust, rocks, and other foreign objects can accumulate in your vehicle vents. Clog in vents impairs the air to circulate properly and may cause overheating. Make it a habit to clean the radiator with soap and water. You may also use a scrub brush. And while you are cleaning the radiator, check the cap for any damage, rust, or corrosion. If you observe any of these, it is time to have it replaced.
Take your VW Passat for a regular check up with your trusted mechanic. This way, your mechanic can treat any problem with the vehicle early on.
When buying replacement parts, it is best to bring the old one with you as reference to make sure you are purchasing the right specification. This will save you another trip to the store if you need to have it exchanged.
