Open the coolant reservoir cap in a counterclockwise direction once the engine has cooled down completely. Fill the reservoir with a 50-50 mix of antifreeze and distilled water to the full mark. Leave the cap off. Start the engine and turn the heater on. Turn the heater temperature control to its maximum setting. Let the engine run until it has reached its normal operating temperature. This will take several minutes if the engine is cold. Shut the engine off and let it cool down completely. Check the coolant reservoir level. Add a 50-50 mix of antifreeze and distilled water to bring it to the full mark if it is low. Start the engine and let it warm up again to normal operating temperature. Shut the engine off and let it cool down. Check the coolant reservoir level and refill if necessary. You may have to go through the warm-up and cool-down procedure up to three times to get all of the air out of the system. Atleast this worked for me good.
