Why Do I Need a Coolant Flush?

Your vehicle’s coolant system is an important part of keeping this temperature in check. And like most vehicle systems, it needs to be regularly serviced to keep working properly.

Cox Mazda offers coolant flushes to Bradenton, Tampa, and Sarasota drivers. Our dealership is located on Cortez Road W, just a quarter of a mile to the east of the Sweetbay Supermarket. To make an appointment with our service team, you can schedule it yourself online or otherwise give us a call!

And to understand exactly why a coolant flush is important, you must first know how your coolant system works, and what ignoring maintenance could mean for your repair bills.

Keeping Things Cool

Your coolant system involves several components; most importantly, these include your water pump, your radiator, and a series of channels that weave through your engine block.

Rather than pure water, the coolant in the system is also made up of anti-freeze at about a 50:50 ratio. Anti-freeze has properties that both lower the freezing temperature and increase the boiling point of the water, allowing the coolant system to stay functional at a wide range of temperatures.

Here’s how the whole system works: the water pump circulates coolant through the engine block, which absorbs heat caused by normal engine operation. The liquid is then carried through the radiator, where it is cooled. The hundreds of tiny fins on the radiator help to increase it’s total surface area and thus the expulsion of heat. The cooled liquid then returns to the engine to absorb more engine heat, continuing the cycle.

When Things Go Wrong

Another vital role of your coolant is to keep the engine from rusting. Pure water is great at transferring heat, but it’s great at rusting vital engine components. Coolant has chemical properties to prevent this, but over time it begins to break down.

A flush helps to replace this coolant, as well as flush out any rust and other metallic debris in the engine that can cause damage. Ignoring this could lead to very hefty repair bills! Check your vehicle manual for when you need to take care of this essential bit of vehicle maintenance.
