How To Change The Antifreeze Step 1 drain. open the antifreeze reservoir cap. place the bucket under the radiator and put on a pair of gloves. this prevents the antifreeze coming in contact with your skin. locate the drain plug at the bottom of the radiator. open it, and allow all the antifreeze to drain into the bucket. Climb under the car and look for a screw that is directly under the reservoir where the coolant goes. make sure you position the bucket directly under this screw. use the phillips head screwdriver to loosen the screw. you don't have to remove it completely. once the coolant begins to dribble out of the hole you can relax until it stops coming out.

Insert the air tool into the radiator neck or overflow bottle. connect the exhaust hose and compressed air line. route the open end of the tool’s exhaust hose into an empty gallon jug or pail. open the valve and let the vacuum rise until the needle reaches the edge of the red zone on the gauge. step 10. Locate the drain plug and loosen. locate the drain plug. this is found on the bottom of the radiator. place a pan under the drain plug to catch old coolant. loosen the drain plug and allow coolant to flow. tighten the drain plug when coolant has stopped flowing. 5. fill the cooling system with distilled water. Step 4 – replacing. use the green scrubber and a rag to gently scrape any debris off the fittings. do not use water; merely blow the debris off. apply a small amount of gasket sealant to all sides of the fittings. do not apply large amounts or the sealer may clog the hose. securely place the new hose onto the fitting.
