I have a leak at my radiator drain. Want to replace the o ring on the drain plug. Anybody happen to know the size of the o ring ?

Thanks in advance !!!

If you have a harbor freight in your area go by kit of both metric and standerd sizes 

 

There like 5 bucks a set worth having in kitchen draw or under the seat of the truck. 

 

Probably not the help your after but is something

I think I got all them kits ^^^^^^ just in case 

I'd just reach into my A/C seal kit and grab a few o-rings till I got the right one.
