So here we are, in the middle of January – why would my vehicle possibly need a cooling system flush now? Most drivers don’t realize that the Cooling System works year-round, in the cold winter months to keep you warm and in the heat of summer to keep you cool. The cooling system keeps your engine running at a consistent temperature to give you peak efficiency. Antifreeze or coolant is the fluid that circulates through the system to lubricate the water pump and protects your engine from freezing and overheating. Over time that antifreeze will break down allowing corrosion and scale build-up to take hold.

What is a Coolant Flush?

A Coolant flush or sometimes known as a radiator flush includes the complete removal of fluid from the system. Some shops perform a cooling system service that simply drains the system and replaces the coolant. However, this procedure only removes about 50% of the fluid and does nothing to clear out the accumulated waste and debris. During a full coolant flush at Hilltop Tire Service, a flush machine is used to completely flush and clear out the system of fluid, scale build-up, and debris. Our experts then use professional-grade BG flushing chemicals that scrub the system clean. Once the system is cleaned, BG additives and supplemental conditioners are applied to protect the system from future corrosion and increase the life of the system. Lastly, fresh, premium coolant is refilled into the system.

How often do I need a Coolant Flush?

Your vehicle owner’s manual will have factory suggested intervals listed, but typically it is recommended to have a coolant flush service performed every 30,000 – 60,000 miles or 5 years, whichever comes first. However, the correct intervals will depend on the age and condition of your car and the type of driving you do.

How do I know if I need a Coolant Flush?

A simple test can identify if the antifreeze has stopped protecting vital engine parts and is allowing corrosion, rust and sludge build-up to form. Stop by your neighborhood Hilltop Tire Service for a free test today.

What are the benefits?

A coolant flush will prolong the life of your cooling system and increase vehicle performance. Regularly flushing the system is reasonably inexpensive and doesn’t take long at Hilltop Tire Service. The lack of it, however, can put your vehicle in the scrap yard.
