    I wish to flush the cooling system of my 05 Tacoma PreRunner, 4.0 engine, and refill it with the OEM Toyato antifreeze. In the past on my non-Toyato vehicles I have flushed in the following manner.

    1. Remove the thermostat and remount the housing. (My Tocoma as the thermostat and housing as one piece construction.)

    2. Remove the top radiator house from the radiator.

    3. Stick a 1" hose into now what would be disconnected top radiator house and point the hose downward to a drain pan.

    4. Start the vehicle.

    5. Stick a garden hose into the top of the radiator neck and turn on the garden hose with maximum force.

    6. Let the water run in and out until it is clear.

    7. Stop the engine.

    8. Cut off the garden hose and remove it from the neck of the radiator.

    9. Open the drain cock of the radiator to empty it.

    10. Leaving the drain cock open, blow through the disconnected top radiator hose to force all water out of the block and it empties through the open drain cock.

    11. Close the drain cock and reconnect the top radiator hose, and remove the radiator cap.

    12. Fill the system with fresh antifreeze.

    13. Start the engine and reconnect the radiator cap.

    14. Once engine reaches operating temperature, check the coolant level. Add coolant as necessary and finally, squeeze the top radiator hose several times to be certain the antifreeze level doesn't drop. It it does, then continue to add.

    My Question Is This: How is this possible on the 2nd Generation Tocoma.

    I bet nobody has really done this yet. I should as well.
    But the whole flushing with a hose isn't an option here the runoff would have PETA ,Heal the bay and HAZMAT here so fast :eek:

    I had the dealer do it after I installed my X1. A bit of the coolant is drained when replacing the thermostat as part of the kit. Decided it would be safer just to let them do it with the pink stuff.

    Just drain the radiator and the block, then fill it back up and bleed it out. Do it at the recommended service interval and you'll be just fine.

    The previous 2 posts say "drain & fill"

    Doesn't the thermostat need to be checked during a cooling system service? Or are people just assuming since the temperature is being maintained properly that the thermostat is fine?
