All About Engine Coolant

Engine coolant not only cools the engine, but also is a lubricant and has anti-corrosion additives. These additives break down over time and needs to be replaced. The type of coolant in your car will determine how often it will need to be replaced. There are two main types of coolant, Ethelyne Glycol and Propylene Glycol. Ethelyne Glycol is usually green and is toxic.  Never open the coolant reservoir with the engine hot. This is the stuff that you need to keep away from your pets. Propylene Glycol is more commonly used in modern cars because it is non-toxic and lasts longer. Both need to be checked regularly with a hydrometer. We check your coolant level every time you're in for an oil change here at our Meineke service department at Rath Auto Resources.
