How do you replace antifreeze in corolla 2003?

Answer 1

To replace the antifreeze in a 2003 Toyota Corolla, start by ensuring the engine is cool, then locate the radiator drain plug and place a container underneath to catch the old coolant. Open the drain plug to let the old antifreeze flow out, and once drained, close the plug. Next, remove the radiator cap and fill the radiator with a new 50/50 mix of antifreeze and distilled water. Finally, run the engine for a few minutes with the heater on to circulate the new coolant, then check for leaks and top off if necessary.
