One of the easiest and most important tasks to prepare your vehicle for winter driving is to inspect the level and freshness of your vehicle’s antifreeze.
The Car Care Council recommends that motorists check their antifreeze every 12 months or 12,000 miles to help protect the engine from freezing and overheating as well as from rust and corrosion damage.
The most common formulation of antifreeze is green in color and uses ethylene glycol as a base with anti-corrosion additives mixed in. Ethylene glycol lowers the freezing point and raises the boiling point of the radiator fluid to keep the water from freezing on cold days and from boiling over on hot days.
Over time, these additives wear out, lessening their ability to protect vital engine and cooling system metals against rust and corrosion. Your vehicle owner’s manual will provide antifreeze usage specifications.
“Inspecting and maintaining your vehicle’s cooling system takes just a few minutes of your time, but it is well worth it when you consider what could happen,” said Rich White, executive director of the Car Care Council. “Cooling system failure is the...
