How do you put coolant in Toyota Corolla VVTi 2002?

Answer 1

1. In order to keep a Toyota Corolla in optimum working condition, you must perform routine maintenance. A good example is the flushing of the radiator. If you neglect this task, debris can accumulate in the coolant system causing the car to overheat. To flush the radiator, you don't need to be a certified mechanic, just follow a few directions.
   • 1

     Move the Toyota Corolla to a flat surface and set the parking brake.

     Pop the hood and check the external temperature of the radiator. If the radiator is cool to the touch, then continue to the next step. If not, wait until it is cools off before proceeding.

     Turn the radiator cap one full rotation to release any pressure inside the radiator. Wait a few seconds and then remove the radiator. Position a bucket underneath the radiator directly beneath the drain plug or petcock valve.

     Open the drain plug and allow the existing coolant to drain completely from the Toyota Corolla's radiator and into the bucket. Pour the old coolant into a sealable container, because it very toxic to people and pets. Dispose of the coolant at a liquid waste recycling center or your local auto repair shop.

     Place the bucket back underneath the radiator, close the drain plug and fill the radiator with distilled water. After a few minutes, open the drain to allow the water to flow into the bucket. Replicate this process until the flush water is free of debris. You need about 3 gallons of distilled water to flush the radiator properly.

     Close the drain plug and fill the radiator with fresh coolant. Then, start the Toyota Corolla and turn the heating fan to high. Allow the car to run until the cooling fan kicks on and off twice.

     Switch off the engine and check the coolant level. If it went down, add more fresh coolant. If it didn't, put the radiator cap back on and close the hood.
