Find a friend who works out at lube shop, or has free access to a pressure flusher

 

yep.. or go to a quick oil change shop

 

i don't trust shops...

 

I bought the gm coolant system flush from the dealer, I works if you follow the instructions.

 

ive used that Gunk (i think thats the name) brand radiator flush. seems to work good, BEFORE ANYTHING ELSE READ THE BOTTLE, IDK WHAT ORDER THE BOTTLE HAS INSTRUCTIONS LISTED. if you dont have an airlift or a flush machine, open the petcock on the bottom of the radiator, let it all flow out, put a garden hose into the top of the radiator, let it fill up, over flow even, then run the car, let it get to operating temp so that the t- stat opens, then drain it again, while running water through it, keep the garden hose going untill you get clean water coming out the bottom, then drain and filler up with coolant, not dexcool, use green shit

 

ahh ok that is exactly how we did it haha.

ill either get the green crud or use that yellow universal stuff, whatever is cheapest. how many gallons does the cooling system use?

 

ummmmmm, i wana say its a 2 gallon system, but having an extra wouldnt be a bad idea

 

alright will do. i got that prestone flush stuff
