Question about allen wrench size for coolant plug

[c1tyhunter]

Hi everyone. I was trying to do a coolant change, but when I got under the car I noticed that I have no tool to take out the plug. It is a hexagonal nut which you fit an allen wrench (hex key) in to. The hex hole on the nut is ridiculously big. I can't find something that large. Does anyone know the size of the allen wrench needed, and where I can get it from? Thanks a lot.

OH yeah, it is for a 2003 corolla

err weird, my coolant drain plug is made of plastic and can be twisted off by hand...my honda was like that too. i thought they're all like that?

anyhow, there's another method of draining: remove ur lower rad hose and drain from there. it's much easier than fiddling with a bolt...and much faster also

that way u dont have to go out and buy an allen key too! see? brilliance yes?

*sigh* I hate the stock radiator on the ae92's... stupid little plastic square heads.. they are so damn annoying.. I had a new radiator on hand but I took it back seeing as I foundo ut I didn't really have a leak in mine... wish now I woulda kept it and installed it.. specially now that I gotta drain the system to install new thermostat.. be a good time to drop a new rad in!
