Volkswagen Squareback: Cooling System Maintenance Tips for Your Car
Although there have been many improvements to today's gasoline engine, they are still not as efficient as needed when it comes to turning chemical energy into mechanical power. Most of the energy in the gasoline is converted into heat. It is the responsibility of your car's cooling system to take the heat away from the engine to avoid overheating. The primary function of the cooling system is to transfer the heat to the air. And over time, one or more of your Volkswagen Squareback's cooling system will wear out and eventually fail. If you want to avoid this scenario, you need to take care of your cooling system and make sure that every component is in good condition. Here are some maintenance tips to remember when it comes to the cooling system:
You can easily inspect the radiator and heater hoses by opening the hood. Check and make sure that there are no cracks or splits and there are no bulging or swelling at the ends. You should replace the hoses if you see any of these signs of damage. Any damage in the hoses can cause the coolant to leak. Lack of coolant in the cooling system is bad news as it could cause the engine to start overheating. When replacing the hoses, make sure to look for a replacement with the correct part number for your Volkswagen Squareback.
- Check and replace a sticking thermostat.
If your thermostat is starting to stick or fail intermittently, then it's time to get a replacement. A radiator cannot function accurately if your car's thermostat is not functioning properly as well. When a thermostat only partially opens, it will cause the coolant to move too slowly through the radiator. And when the thermostat gets stuck shut, the coolant flow will stop and the result will be engine overheating. Meanwhile, when the same thermostat remains open, your vehicle will not warm up properly.
- Make sure that the cooling system is free of air bubbles.
Air pockets or bubbles can form and be trapped within the cooling system. If not removed at once, these bubbles can cause the car to overheat. Anytime your car has a leak or when you have the coolant flushed, you need to check for air pockets. You will need to remove the air by "burping" or bleeding the cooling system. You can consult your trusted mechanic regarding this process if you have no idea about how "burping" is done.
- Make sure to always check the water pump.
Every time you are doing preventive maintenance procedures, you have to make sure to include the water pump in the inspections. A failing water pump is one of the most common causes of overheating. When left unchecked, this can cause irreparable damage to the engine. If you begin experiencing overheating, the water pump is one of the things that you should check first. However, it is advisable to have the cooling system checked at a shop since a defective water pump can be hard to diagnose.
