2021 Subaru WRX STI Radiator Service

Is It Time for Service on My 2021 Subaru WRX STI Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your Subaru WRX STI radiator serviced, but it's still extremely important. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Staying on top of routine radiator maintenance for your 2021 Subaru WRX STI is a huge factor in the longevity of your engine. In fact, Subaru recommends replacing coolant/antifreeze at specific intervals, but it’s a good idea to keep your eyes open for any indication that your radiator is failing. 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. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

Radiator Repair Service for Your Subaru WRX STI

What’s included in a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Subaru WRX STI cooling system. 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. Of all the parts in your 2021 Subaru WRX STI engine, the water pump is one that needs to be addressed ASAP once an issue is identified. This pump ensures that coolant is always flowing through the radiator, hoses, and engine. If it’s not working well (or at all), your engine can easily overheat. Our trained technicians can inspect your car’s radiator hoses and pumps to help you stay ahead of any potential engine problems. From the heater core to the radiator cap, we’re here to give your 2021 Subaru WRX STI the top-notch service it needs. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.

Common Subaru WRX STI Radiator Questions

With regular maintenance and service as needed, you could extend the life of your 2021 Subaru WRX STI radiator. Get answers to common radiator questions, and head to your nearest Firestone Complete Auto Care as soon as you suspect a radiator issue.

  • Why is the coolant light on my Subaru dashboard on? 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? Notice a leaking fluid that's green, bright orange, or pink and feels sticky? It might be antifreeze. Antifreeze is toxic but has a sweet smell and taste that's attractive to many cats and dogs. Do your pets a favor and have an antifreeze leak investigated ASAP. Then hose down the driveway or garage floor!
  • When should my Subaru WRX STI radiator be cleaned? To keep your Subaru WRX STI radiator running well, it’s wise to get it cleaned out a few times a year.
