What does an illuminated coolant temperature light mean for my Volkswagen?

Pay attention to the temperature gauge and lights on your dashboard. If a low coolant warning light comes on or your dashboard temperature gauge keeps rising, it’s likely that your engine is about to overheat (and could leave you stranded on the road). Wait for the engine to cool down, then have your coolant system checked immediately at your nearest Firestone Complete Auto Care.

Can an antifreeze leak wait?

It's better to get it fixed sooner than later. Antifreeze is toxic if consumed, but its smell can attract cats and dogs. Keep your whole family safe by repairing antifreeze leaks ASAP and thoroughly hosing down your parking spot to get rid of any lingering residue on the ground.

When should my Volkswagen Passat radiator be cleaned?

It could be a good idea to have your Volkswagen Passat radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

What can cause my Passat to overheat?

Your Volkswagen Passat engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.

Why does the radiator in my Passat sound like it’s rumbling or boiling?

If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your Passat. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.

Is rust in my Passat radiator bad?

Yes. Rust in the radiator of your Volkswagen Passat can impair its cooling efficiency, cause leaks, and even result in complete failure of the radiator. Over time, rust can eat away at the radiator's cooling passages, forming tiny holes or cracks that can affect its operation. To help prevent rust from causing damage, you should stay on top of radiator maintenance.

Is It Time for Service on My 2020 Volkswagen Passat Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your Volkswagen Passat radiator serviced, but you need to know the signs of radiator malfunction. Your radiator is part of the cooling system. It helps regulate engine temperature. When the radiator isn't working properly, your engine can overheat and potentially break down.

Regular, proactive service on the radiator in your 2020 Volkswagen Passat is a huge factor in the longevity of your engine. Volkswagen recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s also wise to keep an eye out for signs of a failing radiator. You might be driving around (or about to be stranded) with a failing radiator if you notice a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

Volkswagen Passat Coolant Fluid Exchange

What happens during a radiator repair service? When you come to Firestone Complete Auto Care, we’ll begin your radiator repair with an in-depth inspection of the cooling system in your Volkswagen Passat. We’ll do a machine-powered coolant exchange on the system, and then we’ll top off or replace the fluids that were removed (like chemicals, lubricants, and sealants). Lastly, we’ll perform a pressure check to look for leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. Some services for your 2020 Volkswagen Passat engine can wait, but the water pump is one part that you'll want to have repaired or replaced as soon as you discover a problem with it. This vital part keeps coolant moving through the engine, hoses, and radiator. Without it, your engine won't maintain its optimal temperature. Our technicians can take a look at your radiator’s components to ensure everything is operating as it should. If you’re about to lose your cool over a too-hot engine, rest assured that we’re here to give your 2020 Volkswagen Passat the top-notch service it needs. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.
