Change engine coolant on a 2002 Corolla

[dougone]

Can anyone outline the correct procedure to change and flush the engine coolant on a 2002 Toyota Corolla? Should the heater be in the on position? Is there a engine drain plug or should I used the radiator drain plug? Are there any breather values I should be using to get the air bubbles out? Is Toyota long life coolant the best option?

heat should be set to full hotness. there should be a engine drain also a radiator if you can get to both that would be good in flusing. toyota long life(red) or short life (light pink) is the best to go for any car. for bleeding i personaly just fill the radiator and try to squeese out what ever air i can from the hoses. then i start the engine off with the radiator cap off and keep filling it till it stops going down after a short while.

If its really dirty and you want a good flush, follow this.
Drain the coolant as instructed. Plug the drain again, remove top hose. Remove thermostat, put neck back on without thermostat. Reconnect low hose if you had to remove it to get thermostat out. Put garden hose into rad from top hose openning. Leave rad cap off. Turn on the garden hose so water keep going into rad. Make sure hose stay in rad, start the car with heater on. Keep idling until clear water come out from top hose openning on engine side.
Follow flush instruction shown on flush bottle. With thermostat out, top hose reconnected. Make sure you idle the car till water get hot. Rev it a bit to help heat up faster.
Make sure you put thermostat back after you finish
