How to Bleed Air From a 22RE Radiator

Anytime you open the cooling system, you run the risk of allowing air into the system, rendering it less efficient. This might be caused by a leak, draining and refilling the radiator or simply alowing the coolant level to drop. If you open the radiator cap and the coolant level doesnt reach the rim, there is air present in the Toyota 22RE cooling system and you need to properly remove it to ensure optimal performance.

Instructions

    1

    Ensure that the engine is cool. Remove the radiator cap and see the coolant level reaches the rim. If not, add coolant as specified by the owners manual. Add coolant to the overflow reservoir until it reaches the "Full-Cold" level.

    2

    Place a drain pan under the radiator drain valve, on the bottom passenger side of the radiator. Use your fingers, or a pair of pliers if necesary, to open the radiator drain valve and allow a small amount of coolant to drain out. Close the valve.

    3

    Refill the radiator. Slowly squeeze the upper radiator hose to ensure it has no air inside. Repeat this a few times and top off the radiator. Replace the radiator cap.

    4

    Start the vehicle and turn the heater control to "High." Allow the vehicle to warm up until the upper radiator hose is hot to the touch. This means the thermostat has opened and coolant is flowing through the system. Turn off the engine.

    5

    Check the radiator cap to see if it is cool enough to touch. Place a rag over the cap and slowly open it, releasing pressure a little at a time. Top off the radiator and the overflow reservoir, if necessary. The system is now fully primed with coolant and free of air.
