2004 Silverado 5.3 Radiator Drain

[tdub8517]

Am I blind or is there no drain on my radiator? No fill neck either. Anyone ever change their coolant ? If so , is there a drain? Fill through the overflow bottle?

Check for a drain at the bottom of the lower hose or pull the hose (yeah it's not fun). Yes, refill is through the overflow tank.

I actually found the drain , drivers side at the bottom. Not sure how to open it but at least found it.

If it's like the one on my wife's burb. you turn the hose down and there's a valve you turn.

Just turn 1/4 turn? Trying to be careful as to not break the plastic tank. I assume just pliers. I know I am probably sounding a little on the dumb side , just dont want to break it.

I believe it need 180* to open fully. Been awhile tho.

Do you remember if you had to pull it out or just turn it? ( I HATE PLASTIC )

 

[ak diesel driver]

just turn as I recall
