Not antifreeze, that is special oil for the ac compressor with some dye in it to help trace refrigerant leaks.
At the radiator or at the coolant resivoir.
=To properly flush the antifreeze on a 2002 Yukon you will need a antifreeze vacume system you will need to start the car and have it running turn on all the heating modules to high and have the car reved at about 1.5 r.p.m, or a little higher to activate the vaccume this will start sucking the old antifreeze out. When the radiator is empty{you will know when it is empty because there will be no more antifreeze coming out}you can then fill it up with half and half antifreeze[half water half antifreeze].=
To change the antifreeze on a Mercedes, locate the drain plug on the bottom of the radiator. Drain the fluid into a pan and refill it.
vehicle will overheat. just dump the oil and antifreeze , flush engine and refill with clean oil
Do not run the engine. You need to drain out the fluid antifreeze mixture.You can then refill the power steering fluid.
Drain coolant. Refill with correct water anti freeze mix
Pull your lower radiator hose, replace it when all fluid is out, and refill it.
I assume you are referring to a fixed leak in the cooling system. In that case, add a solution of 50% antifreeze and 50% water to refill the system.
Either at the top of the radiator or fill through the coolant recovery tank
A 50/50 mixture of antifreeze and distilled water.
The larger hose is low pressure
If it needs refilling then it has a leak. The leak needs to be repaired. So, take it to a professional for repair and recharging. You have neither the skill nor the proper tools to do this.
