What does the coolant light on my Subaru dashboard mean?

Your engine might be about to overheat. If your low coolant light is on, pull over in a safe area and wait for your engine temperature to go down. Once it’s safe to do so, bring your car to your nearest Firestone Complete Auto Care to have the coolant system inspected.

Is an antifreeze leak dangerous?

Don’t ignore puddles on your driveway or garage floor. If you see a green, bright orange, or pink fluid puddling under your car (it might be sticky, too), it could be antifreeze that’s leaking out of the engine. Antifreeze has a sweet, attractive smell to cats and dogs (and it’s highly toxic to them), so look out for your pets! Repair any leaks as soon as possible, then carefully wash away any remaining fluid that’s left behind on the driveway or garage floor.

When should my Subaru WRX radiator be cleaned?

Cleaning your car shouldn’t be limited to the parts you can see. Regular cleaning is good for your radiator, too! When you take your Subaru WRX in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.

My WRX overheated! What can cause that?

Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Subaru WRX engine to overheat.

What can cause a WRX radiator to make boiling or rumbling sounds?

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

Is rust in my WRX radiator bad?

Yes. Rust in your Subaru WRX radiator could reduce cooling efficiency, cause leaks, and even lead to radiator failure. Left unchecked, rust can damage the radiator's cooling passages causing small holes or cracks in the radiator. Maintain your radiator system to help prevent rust.

When to Service Your 2018 Subaru WRX Cooling System

It can be tough to know when to have your Subaru WRX radiator serviced if you don't know what it does, but it’s vital to know what to look for. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. When the radiator isn't working properly, your engine can overheat and potentially break down.

Regular, proactive service on the radiator in your 2018 Subaru WRX is essential for long-term engine health. Subaru 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 could be on the verge of a radiator-induced engine breakdown 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. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

Radiator Repair Service for Your Subaru WRX

What happens during a radiator repair service? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Subaru WRX’s cooling system. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check 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 2018 Subaru WRX 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 2018 Subaru WRX the top-notch service it needs.
