Step 1 Add a mixture of one-half water and one-half antifreeze to the radiator. Fill it right up to the top.

Step 2 Fill the overflow/coolant reservoir with the same 50/50 mixture.

Step 3 Leave the radiator cap off, turn the engine on and let it run until the radiator " burps": You will see the coolant level drop and may see or hear a large air bubble come to the top as the system burps.

Step 4 Keep an eye on the temperature gauge throughout this process.

Step 5 Refill the radiator to the top and coolant reservoir as needed.

Step 6 Put the radiator cap back on.

Step 7 Note that if the engine runs hot after this procedure there may have been another pocket of air that " burped.&Quot; Let the engine cool down and then add more coolant to both the radiator and the coolant reservoir.
