[Coolant Purging Question]

I did it according to Mr P..... instructions which was close to the manual other than the bleeder screws. I saw the bubbles coming back to the tank, the temperature stayed at normal so it looks OK. Thanks for the replies and the insight.....

Some more questions; after driving the SS about 5 miles or so I checked the hoses. It doesn't overheat as the gauge shows the temp. normal. The top radiator hose is hot and can be depressed. The lower radiator hose isn't hot to the touch and also can be depressed. Both the hose going to the throttle body is hot and hard and the hose going to the surge tank (near the top of the tank, not the puke hose) is hot and very firm when squeezed. Do you think I have air in the system? The level in the tank is good.....

Thanks again

very good instructions.

 

theres a faster, more efficent way but requires a tool or machine. you can pick one up from sears, i beleive (i get mine from snap on or matco). its basically a tool that goes into the overflow tank, sucks all the air out till the hoses collapse, and then you let the built vaccum pressure syphon the new coolant in. thus leaving no air pockets and adding just the right amount of coolant.

I just changed my water pump on my 04 Siverado SS. The service manual says to open the bleeder screws when adding the Dex Cool, then close them after the fill. Where are the "bleeders" . The instructions are different from the 03's, I'm wondering if I can just follow those instead.

thanks
