Hi Mariano,

This is one I got many years ago. Pretty sure they are the correct ones. Fit nicely in the heads with the pipe holding it down as Tony mentioned.

Marked "Cleveland Ohio" "Made in USA" and a "6" and "41" which I would think are the date of manufacture.

Cheers,

Hi Mariano,

Here is some info straight from the Ford Special Pattern Vehicles Handbook.

Cheers,

The images posted by Mariano and Jacques are of the original "Bellows" design thermostats. They fit snugly into the outlet of the head and don't pose much problems with shifting. But these are no longer manufactured in that style anymore, with only 2nd hand or NOS available, which may be 50 years or more in age.

The modern style of thermostat pictured below are all that are made these days, and can be specified in a wide range of suitable temperatures. However, without the cylindrical body of the Bellows type, they do not locate quite as well in the head outlet, and need some sort of physical restraint to stay put ON the outlet, otherwise they lift off and can allow coolant to flow past it.

Yes, these would have been correct, but!,... they are alcohol filled and more importantly, they usually fail in the closed position.
A more standard type (modern) wax type thermostat is more likely to fail in the open position (less likely to cook your engine) and I believe, are more reliable.
I bought thermostats for my carrier from a parts supplier that had a big selection of thermostats. Some cars use smaller dia. wax stat. They fit in the top hoses on top of the heads. Some guys cut down the bigger ones, but that looked a bit hard to me.
So, What I installed were Tridon (brand)TT203-180. Obviously 180 degree but they have worked fine. (the higher your operating temperature, the more efficient is you engine, as long as it is not overheating) They are 44mm in dia. and are used in a v6 Holden (VX, VY)

Good Info Lynn,

On that basis I will just keep them on the shelf and go the more modern ones. Think I paid $10 about 25 years ago for the two so no great loss!

Very good all the comments!
I will discard looking for the originals and place the modern ones!
Thank you very much!!

Mariano,

Please see these pictures of a Ford CMP radiator pipe compared to one from a Universal Carrier.

As others have mentioned, the angles might prove to be a problem.
