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.

Step 1

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.

Step 2

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

Step 3

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

Step 4

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

Step 5

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

Step 6

Top off the radiator with DEX-COOL antifreeze.

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