CSF Radiator Drain Plug

CSF Radiator Drain Plug
I have a 3 row CSF radiator in my 86 Toyota truck, It looks like the CS 2314. It appears to be leaking at the drain plug. I'm having some difficulty finding the right size replacement. The oem size replacement is too large: M14x1.25. The plug I need looks to be M10X1.50. Any suggestions? I thinking the original CSF plug may have a rubber washer or o-ring to prevent leaks.

I think that I have one of these radiators laying around... it has a plastic screw-in plug, with a rubber washer of some kind... i'm assuming that the plug is screwing into metal, and not some kind of rubber insert into metal.
can you pull the plug out, and take it to your local hardware store? they should have an assortment of rubber washers.

Options in 2022
Old thread, but I was just looking for this myself. My truck had a CSF 2056 radiator already when I purchased it. I had the radiator out yesterday to do my timing belt and water pump, and I found the threads on the drain plug were already shot - which of course caused the plug to slowly leak when I screwed it back in.
I went and picked one up at the Toyota stealership, but of course I it didn't fit when I got home. I didn't even realize I had an aftermarket radiator until then.
After finding this thread, I did a little more research. I thought I would update it with current info. Here are two options with active links (2022):
I would generally prefer a petcock like this , but I haven't found one in our metric size anywhere.
I ultimately settled on the brass bolt with the rubber washer. Nothing to break, and the soft brass is easy on the radiator threads. I also like that very little protrudes from the radiator. My truck sees a lot of time off-road, and I like parts I never have to worry about getting snagged on or broken by anything. Just my $.02
