Most people only think about their vehicle’s antifreeze/coolant during extreme weather conditions, or when it’s too late and their overheated vehicle is stranded on the side of the road.
The truth is, antifreeze/coolant is a year-round concern.
It helps keep the engine’s cooling system from freezing up in cold weather and from boiling over in hot weather.
In order to help lower exhaust emissions, modern engines run at very high operating temperatures. Cooling system temperatures of 110 C are not uncommon.
But it’s not enough simply to check the level. A professional technician should also test the condition of the coolant and the coolant concentration to ensure that it doesn’t need to be changed.
