If anybody is draining their radiator between now and Friday I would appreciate it if you would measure the o-ring on the drain valve. It will pull out of the radiator. Thanks!

 

why don't you just drain it yourself?

 

Just get a pack of O-rings with assorted sizes, up to about 1"

 

I'm going to... But would like to have the o-ring before I do that way I don't have to make a special trip to the parts store.

That's what I'll probably end up doing. Just wanted to pick everyone's brain to see if anybody knew.
