do the 2004 silverados have a drain plug on the radiator. if so mine is flawed becouse it doesn't have one it looks like it should be there but there is nothing there.

 

The 04-05 trucks do not have the drain.

 

I think I spent about 30 minutes on my Radix install for my 2004 H2 looking for a petcock on the radiator. I thought for sure it must be there somewhere because the instructions said it was. I ended up taking the top hose loose and stuffing a long siphoning hose attached to a pump into the engine to drain it low enough to change the required parts. Worked great.

 

i couldn't find one on my 03 either when i changed my thermostat

 

no $hit?! how are you supposed to drain it?

 

hmm.. theres not even a little screw like on the 01's? Maybe there is a vavle and no hose? IDK.

Thats really odd... I would say screw it and take the whole radiator out but you'll have coolant EVERYWHERE if your not careful.

Wonder if it would be in a Haynes manual...

 

Was it a GM 'cost-cutting' thing or do they want to discourage us from attempting any work on them?

 

ok so i'm not completely retarded i feel better now thanks.

 

I'd love to know the justification for this one. Whoops!!!!

 

if your refering to my post i fixed it. i might be some dumb but not plum dumb
