How to drain radiator - 2004 Pontiac Grand Am
To drain your radiator, you will want the engine to be cold so you do not burn yourself. You will start by locating the pep-**** valve on the lower portion of the radiator. This may resemble a knob, or screw of some sort. You will then place a container under that area to catch the fluid/antifreeze that will come out of the radiator. Then you will take the radiator cap off (some models have the cap on the reservoir). Next you will loosen the pep-**** valve, and the fluid will then begin to drain. Once the fluid has drained, you will tighten the pep-**** valve, and then refill the system with the correct mixture of antifreeze and water. Remember that water is the catalyst that makes the antifreeze work, so make sure you use a 50/50 blend, and make sure that you use the recommended type of coolant, some models require that you use dex-cool, which is a synthetic coolant. To ensure that you have properly filled the cooling system to its correct capacity, you will want to start the car, turn on the heater, and add coolant until the system is full while remembering that the reservoir needs to be filled as well.
Disconnect lower radiator hose and drain coolant into a drain pan. Look for hose on bottom side of radiator, use screw driver or socket and take off lower hose and drain coolant. For a good measure i would flush out radiator with some fresh water.
