How do you change antifreeze on Toyota mr2?

To change the antifreeze on a Toyota MR2, start by ensuring the engine is cool and then locate the radiator drain plug at the bottom of the radiator. Open the drain plug and let the old coolant completely drain out. Next, close the drain plug, fill the radiator with a 50/50 mixture of new antifreeze and distilled water, and run the engine with the heater on to help circulate the new coolant. Finally, check for leaks and top off the reservoir to the proper level.
