2003 Silverado cooling system
I know it isnt an LS1 but I have always had good luck here when I have a problem. I just changed the water pump on a 2003 Silverado 4.8 and need to know if there is a bleeder valve for the cooling system. It has no radiator cap so I figured it would have to have one, but cant find it. Thanks in advance.

There has to be Rad cap of some sort. Might not be on the rad its self, but on the overflow tank. As for bleeders, look around the hose fittings, my guess is thats where the would be.

If it did have a bleeder it would probably be on one of the heater hoses. Just follow them and see. Without a radiator cap how did you fill it with coolant?

no bleeder valve on it, just fill up the surge tank and drive it, it purges itself. recheck after you drive it
