What Does the Cooling System Do?

Internal combustion engines like the one in your Volkswagen are hot. They produce enough heat actually to warp and melt the metal of the engine itself! The cooling system is what keeps this from happening. The water pump moves coolant (also known as antifreeze) through hoses in the engine, where it picks up excess heat. After this, it moves to the radiator, where it’s cooled down by airflow and increased surface area. After the coolant is cooled back down, it begins the process all over again. If anything is wrong with the cooling system, the engine runs the risk of overheating.

Benefits of our Pre-Mixed Coolant

• Protection against freeze up to -35* F
• Protection against boil-over 264*F
• Main benefits: helps protect the cooling system against corrosion and boil-over during the summer, and offers protection against freezing during the winter
• North Penn recommends replacing the coolant every 3 years or 45k miles and we offer a free freeze/boil temp test through Service Xpress

What Are Signs That My VW Needs Cooling System Service?

Of course, there are many potential problems with the cooling system. The radiator fan (which helps cool down the coolant when your VW isn’t in motion) could stop working, or the coolant hoses could develop a leak and lower your coolant level. But no matter what the problem may be, there’s one consistent symptom: an engine that runs hot. Keep an eye on your vehicle’s temperature gauge. If it begins to creep into the red, bring your VW in for a cooling system inspection so our technicians can take a look and give it a proper diagnosis.
