Subaru Coolant Service

Subaru Coolant Service at Larry H. Miller Subaru Boise

The coolant of your Subaru represents an integral fluid, which helps keep your engine from shutting down in temperature extremes and prevents corrosion. As with most fluids, the coolant of your Subaru will deplete, or expire, necessitating either a refill or a flushing. No matter which process you need, we recommend using Subaru-brand coolant, which you will find available here at Larry H. Miller Subaru Boise. Feel free to order more coolant from our parts department or schedule a service appointment when your vehicle comes due for a coolant flushing.

What Exactly Does Coolant Do?

As its name suggests, the coolant can play an integral role in keeping your engine from overheating on a hot, summer day in Boise, ID. However, the coolant also helps keep the engine from freezing during the winter-months; hence, its colloquial name "antifreeze." Subaru-approved coolant also keeps the engine and other components from overheating.

When Does my Subaru Need a Coolant Flush?

Our technicians can check your coolant reservoir levels around every 30,000 miles, when the coolant typically expires and begins to loose potency. However, if you tend to commute during extreme temperatures, you might simply need a refill of antifreeze rather than an outright flushing.

Do I Need Subaru Coolant?

We highly recommend using brand-labeled coolant as this formula will last the longest, as with the Subaru models themselves. When you use Subaru coolant, you also take a lot of the guesswork out of searching for off-brand formula. You also eliminate the risk of engine damage from selecting the wrong generic brand.

Do I Need to Dilute Subaru Coolant?

Not usually, no. Most Subaru STI Super-Coolants come pre-diluted with a 50/50 concentration of formula and water.
