Model T Ford Forum: Forum 2015: Radiator drain question
Top of pagePrevious messageNext messageBottom of page Link to this message  By Corey Walker, Brownsboro TX on Sunday, September 06, 2015 - 11:07 pm:

Did all Ford radiators come with the same familiar petcock? I have a round tube low radiator and it had a pipe plug where the petcock goes. I lost the plug and went to screw in a petcock and the hole is too big. I can't remember if it is a Ford radiator or not. I bought it a few years ago from somebody on the forum that was getting a new radiator, Mike Walker I'm thinking but I can't remember. Just wondering, no big deal the plug works fine I just need another.

A modern radiator petcock will work there also.

Corey, The standard thread for the radiator drain is 1/8" pipe. All cars (not sure about the water pump 09's), used the same thread, and a similar petcock. The crankcase (2X), gasoline sediment bulb (1X), and radiator (1X) used the same petcock).

Maybe it is an old aftermarket radiator. I've got plenty of Ford petcocks but they don't fit. I'll just have to go to the hardware store and get a plug. It's 3/16 or 1/4 pipe thread.

Corey, You could also try a "bushing" to adapt the thread from 1/4" pipe to 1/8" pipe. Then the standard 1/8" petcock would work. These should be available at the hardware store.

I'll try that if I can find a good enough hardware store around here. It is almost impossible anymore to find slotted head screws.

Corey, good to see you back on here. I sold you that radiator. It's been awhile, but as I recall, the original threads were bad and it had been drilled out for the 1/4 inch plug. As David M said, all you need is a bushing and you'll be good to go. Dave

My T's have the sane petcock that is used in crankcase. I always thought they were the same.
They both have 1/8" pipe thread.
You can still find them in junk boxes at auctions and swap meets. Seems like they always wound up there.
