I want to get one of those new drain plugs from fram that you can screw the hose onto the drain plug and it lets the oil out. I need to know what size bolt it is though. My helms doesn't say!!!!!!!!!!!!!!!! So if anyone has this yet or knows what size it is... I would appreciate it. Thanks.

 

stock drain bolt? I think its 17mm

 

You'll need to know the thread angle and pitch plus diamiter. Find a thread guaging kit. They look like saws.

 

and yes its a 17mm
