remove rad cap. place a large pan under the car. open the drain plug on the bottom left of the radiator. loosen the 2 bleed screws. one is on top of the thermostat housing the other in a t connector next to that. after rad is drained, move pan under engine blockand remove the block drain plugs or knock sensors (which doubles as plugs on some models) on both sides of the block. disconnect reservoir hose and remove reservoir to flush it. place a hose in the ra filler neck and run til clean water flows through all drain points. install the plugs and reservoir and theres hose and rad drain plug. use the correct coolant. GM recomends adding coolant system sealeradd coolant slowly. close bleeder screws when coolant coming from them is bubble free. add to the reservoir. keep an eye on the level after a few miles and check for leaks.
What does your owner's manual say to use? If low silicate is not listed then drain and refill with the proper coolant.
This is difficult so pay attention- (1) Remove the radiator cap (2) Start filling the radiator with a proper mixture of water and coolant(Most climates us a 50/50 mixture) (3) Once the coolant reaches the radiator neck stop filling and let the coolant go down, you can speed this up by starting the engine and letting the coolant start to circulate. (4) keep doing this until the coolant level remains at or near the top of the radiator. Happy Motoring!
yes you can, just look in your manual for proper procedure and you are set.
Remove the coolant reservoir, flush it out, reinstall it and refill with proper coolant.

You must make sure that you have purged all air from the coolant system. An air bubble will not allow proper flow of coolant and could also cause the engine to overheat. Add coolant into resevior and leave top off with engine running. Add more coolant as required. If temp gets too high with cap off and coolant starts to back out of resevior, then replace cap and allow to cool. Remove cap after cool and top up coolant again and repeat procedure.
