Taking good care of your Volkswagen is critical in extending its lifespan. In particular, the cooling system of your VW is one that can easily deteriorate because of constant use and exposure to engine heat. As a result, you may have to replace this part most frequently, especially without proper, regular care.
Read on to learn more important ways of properly maintaining your VW’s cooling system:
Keep it Clean
Keeping your engine and engine compartment, as well as all fins and grills, as clean as possible is key. When an engine is clean, it’s more apt to run smoothly and not overheat as quickly.
Replace Coolant and Hoses
Keep an eye on the factory-recommended intervals to replace the coolant, taking into consideration the proper mixture, tire and volume. Make sure the coolant system is free of air before placing the radiator cap back on. Replace all cooling system hoses, including upper and lower radiator, heater, bypass, and manifold coolant hoses. You should do this even if you don’t suspect a problem – about every two years.
Replace the Thermostat
Replace the thermostat and use the original temperature setting, as the electronics in your car may use those same settings when it comes to other controls. It’s not wise to substitute. While we’re on the subject, when you put the radiator or expansion tank cap on, you should likewise use the original pressure-setting and OE-type equivalent. This is because after-market substitutes don’t always feature the exact measurements which may result in a loose seal and coolant spillage.
Replace and Adjust Belts and Pumps
Adjust or replace the water pump drive belt at recommended intervals. Always inspect the belts when working on coolant system components. When it comes time to replace the water pump, buy an OEM pump when you suspect failure or whenever you replace the timing belt and tensioner. Be cautious of overheating.
Replace Clutch or Blade
Replace your fan clutch or blade as needed. Remember, the temperature gauge will indicate when to change the fan clutch so keep an eye on it. If you have to change out the temperature sensors, consult with your VW technician because they have the proper diagnostic equipment necessary to troubleshoot the problem.
Stay on Top of Regular Maintenance
Proper maintenance is key when it comes to the impact on timing, idle speed, exhaust and other systems that affect your engine’s temperature. The Volkswagen cooling system is designed to function in conjunction with all other vehicle systems. When one fails to work properly, they are all jeopardized.
If you decide to DIY a repair of your cooling system, here are some typical parts you may need:
- Water pump
- Water pump drive belt
