How do you change coolant on 2003 gmc Yukon?

Answer 1

To change the coolant on a 2003 GMC Yukon, start by ensuring the engine is cool, then locate the radiator drain plug at the bottom of the radiator and open it to drain the old coolant into a suitable container. After draining, close the drain plug and remove the radiator cap. Mix the new coolant with distilled water according to the manufacturer's specifications, then fill the radiator and reservoir with the new coolant mixture. Finally, run the engine until it reaches operating temperature, check for leaks, and top off the coolant if necessary.
