Over time, motorists have gotten the idea that engine coolant matters just twice a year… preparing for winter, and setting out for summer. But the truth is, coolant has little to do with the outside temperature, and everything to do with internal temperature.

Coolant is the TRUE LIFEBLOOD of your engine. If an engine runs just 18 degrees above or below normal operating temperature, you can risk serious and costly damage. Because the cooling system is connected throughout your engine, keeping the right coolant chemistry and maintaining proper coolant levels needs to be a top priority for sustaining the overall health of your vehicle.

When Was the Last Time You Checked Your Coolant?

88 Million Vehicles on the road today are low on coolant, have you checked your coolant levels lately? Each time you open the hood is an opportunity to monitor coolant levels and get a reading on your vehicle’s health. Low coolant levels can lead to rust, corrosion, and cavitation of critical cooling system parts such as the radiator, heater core, thermostat, and water pump.
