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.

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):

• Dorman 61110 Radiator Drain Cock
  Dorman 61110 Radiator Drain Cock
• Dorman 090-038CD Oil Drain Plug Standard M12-1.25, Head Size 14Mm
  Dorman 090-038CD Oil Drain Plug Standard M12-1.25, Head Size 14Mm

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

Hey, I ran into this same issue last year. After many years of use and draining/removing/installing the CSF 2314 I have, the plastic threads were trashed (my fault for over tightening, in all fairness those plastic plugs last if treated correctly), but a problem nonetheless. The 2314 I have is either an M10 or M12 1.5 plug, I’m forgetting at the moment. I searched but came up empty on a quality drain clock (we prefer) in brass with the correct size and threads. Draining is so much easier with those pet cock style plugs. Defeated, I went to a larger hardware store and bought the shortest black anodized bolt with a rubber washer, haven’t had any issues yet. But I’ve checked many times due to being nervous about not going very tight on the steel bolt in brass radiator threads. I definitely like your fix of softer brass vs. steel for the threads. I may order one.

check the o-ring .. most likely the cause
