Replace Cadillac SRX Coolant

by Zyon Silket

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.

Place a 4-gallon container under the drain valve on the radiator. Open the drain valve with a ΒΌ-inch-drive ratchet and drain the fluid into the drain pan. Do not leave the fluid in a container without a lid. Drain the fluid from the pan into a sealable container. Close the drain valve once drained.

Open the lid on the fluid expansion tank (overflow tank) to allow air to escape while you fill the radiator.

Open the radiator cap and place a large funnel into the filler spout.

Pour 2 gallons of DEX-COOL antifreeze into the radiator, then pour 2 gallons of distilled water into the radiator.

Start the engine and allow it to run for five minutes to push air out of the coolant system. Stop the engine.

Top off the radiator with DEX-COOL antifreeze.

Close the lid on the fluid expansion tank and put the cap back on the radiator.
