Vehicle Coolant System

All gas-powered vehicles – from Audi to Volkswagen – run on an internal combustion engine. Combustion causes the gas to heat up and expand, producing a lot of energy that powers the car. The cooling system circulates coolant (a mixture of antifreeze and water) around the engine, absorbs heat, and disperses it through the radiator. If the cooling system fails, your car can overheat, and the heat can even cause extensive engine damage.

Don’t let this happen to you! Protect your engine by keeping an eye out for these potential issues with your cooling system.

Coolant leaks:
Do you see liquid on the ground under your car? It could be various things, but if it’s bright green, yellow, or pink, it is likely coolant. Antifreeze comes brightly colored and is toxic to pets, bad for the environment, and very messy. This can compromise the pressure of the cooling system. If you are constantly needing to add coolant, it may be leaking and you might not realize it.

Overheating Vehicle:
If your car already overheats on a hot day or during a long drive, that’s a sign that there could be an issue with your cooling system. It’s best to get it checked out before the problem becomes worse.

Never Changing Out Your Coolant
Many fluids in your vehicle need to be flushed out and replaced, including oil and brake fluid. Your coolant needs to be flushed as well. Over time, coolant picks up sediment that can clog the system and decrease performance. By exchanging the coolant, the experienced team at EuroCar Service removes the old coolant and sediment, putting in new fluid. Antifreeze contains anti-corrosion additives, that are important to coat internal surfaces of the cooling system, protecting against oxidation (which can lead to leaks) and scale (that clogs the system). As you drive, the protective coating is reduced and system components can be left vulnerable to corrosion.  That’s why we recommend routine coolant flushes, and especially if any part of your cooling system is replaced. For example, when you put in a new water pump it is not coated with anti-corrosion additives.  If your anti-corrosion package is already depleted, the new water pump will immediately be subject to corrosive elements that will quickly start to reduce its life cycle.  If you change the coolant when the new water pump is installed, it will be protected the first time you start the engine.If you have any questions about your cooling system, contact EuroCar Service.
