Replace Cadillac SRX Coolant
It is a good idea to replace Cadillac SRX coolant every year to prolong the life of your engine. The coolant used in all General Motor vehicles, including the Cadillac SRX, is DEX-COOL. That's a well-known trade name for organic acid technology antifreeze. It's orange. GM says any other coolant fluid than DEX-COOL will damage the Cadillac's radiator. Replacing the fluid in your radiator does not require a trip the auto garage. You can do it yourself.
