Defiantly not an OEM radiator or drain plug
The factory plug does not seal at the threads, it has a smaller diameter portion at the front where an o-ring makes the seal in a matching smaller area in the radiator, the one above appears to seal under the head, here are pics of the OEM plug and o-ring together
Plug (cock) 16417-15210
O-ring (packing) 16418-15520
They will not work on that radiator.

Right, but how do I know what thread pitch I'd need if it's not a factory radiator, and I can't exactly drive the LX down there.Any ideas where I could look on the radiator to find out what kind it is if it's not factory? I'm a radiator and bolt moron.
most after market radiators are not marked with the manufacturer, they are made by one company, distributed by another, and sold to the consumer by a third,
E is right unlike the OEM that one looks like tapered threads, If it is NPT, it looks like about 1/4" NPT, if it is tapered but not NTP it will be BSP (british standard pipe) or metric pipe thread,
Another reason to go OEM on radiators. That white plastic plug looks like the non weather resistant stuff that cheap toys are made of. It decays with heat and UV and I've dug my nails into it before. The Toyota plugs are not. In fact, the one I looked at in the garage was in a radiator with 290,000 miles on it and even the O ring at the tip was in perfect shape.
Somebody saved about 3 cents making that radiator, and you wonder where else they elected to save a few more cents??

yeah, the more I think about it, the more pissed off I get. this should be such an easy fix, and yet it's turning into a big PITA. Oh well, live, learn, then go back to OEM, right?
