I need to remove the cylinder block plug to install a block heater, anyone know what size hex wrench it takes? a lot bigger than anything in my metric box so I need to purchase or borrow the right size. TIA

It's 14mm. If you have an autozone, that's the only place I found that had allen sockets large enough. It came in a package of 3, 12, 14, and one larger one.

 

I did mine, I remove it with an allen wrench sorry I don't remember de size

The only place I've found one of those separate from a set is online. There are usually a number of them on eBay. I think they're a common size for Mercedes-Benz oil drain plugs and other import plugs.
