How do you change coolant on 2005 Buick Lacrosse?

Answer 1

To change the coolant on a 2005 Buick Lacrosse, start by ensuring the engine is cool, then locate the radiator drain plug at the bottom of the radiator and place a container underneath to catch the old coolant. Open the drain plug to let the coolant flow out, and once it’s drained, close the plug and refill the radiator with a proper coolant mixture (usually a 50/50 mix of coolant and distilled water) through the radiator cap. After filling, run the engine with the heater on high to circulate the coolant, checking for leaks, and top off as necessary. Finally, check the coolant level in the reservoir after the engine cools down.
