drain petcock
While were on this big cooling system kick for the summer.... I have the plastic passenger side petcock you have to take the grill off to get to. Seems I can spin and spin the valve but nothing comes out... any ideas?

Pulling the bottom radiator hose off will get your radiator to drain. However, your pepcock is jacked up or the bottom of the radiator is plugged with crud or rust. If you were spinning on the pepcock and it wouldn't drain today, it will most likely start to leak or pop out when you least expect it like when climbing a mountain pass or out in the middle of the desert. Drain the radiator by pulling the lower hose if you have to but, definitely get to the bottom of why your pepcock is not working.

Thanx man I was thinkin the same thing. Already drained it by cutting lower hose(tryin not to make a mess) gonna be hard to flush without a petcock.

My whole intake/exhaust manifolds are off. It was very easy just didn't want a mess. Cut it cause if I just pulled it off it would have just flowed and my catch can wouldn't hiave caught it fast enough.
