Engine Coolant

The coolant in your car keeps the engine cool during the summer months and prevents the fluid from freezing in the dead of winter. But over time, engine coolant breaks down and requires replacement.

Engine coolant becomes corrosive as it ages, and can damage your cooling system's components if left unchanged.

The basic principle and design of radiators basically remained unchanged since they first were introduced on the earliest automobiles. They still use tanks, tubes and cooling fans. The water pump passes fluid through the tubes, where heat is dispersed through the fans. Today's tanks are commonly made of plastic and aluminum, and a radiator can last the lifetime of your vehicle--as long as you replace coolant at manufacturer's suggested intervals.

Coolant is your radiator's lifeblood, and every vehicle manufacturer has its own specifications for what type of coolant should be used for a specific engine.

Simply adding water or any type of coolant can hamper your vehicle's performance by introducing contaminants into the system.
