1933 model B water pressure?

[FrankWest]

There is a dealer that sells a 3 lb pressure valve he says to hold the water in the model A and model B engines and help them run cooler? Does that idea hold any water? Sorry for the pun!

Frank,

How about a link to this product? The 3 lb sounds ok but I am a little confused about what he is selling.

Yes, it works. I bought one for my '33 as well as had him rebuild my water pumps, distributor, and coil.
Absolutely no problems with any of those items. The pressure valve maintains a closed cooling system, thus preventing the overflow tube from leaking anti freeze every time you park the vehicle.

Just a bit of basic physics, however....it won't make your engine cooler. It will only raise the boiling point of the coolant in your engine. Your engine will still run at the same temperature.

Frank,
Why would you want your 4 cylinder to run cooler, if it is like a Model A or '32 (and I must admit I don't know the answer) people put in thermostats to make them run hotter (it improves the efficiency of the engine)? If it overheats, fix the problem. I wonder if the '34 radiator cap meets the requirement "Tight radiator cap required"? Skip has a good reputation you might ask him if one is needed with a 4 cylinder engine and can you use it with a stock radiator cap (I assume) and a stock water pump(I assume)? My advice would be to drive the car a while and then decide if you need one.

This valve has nothing to do with raising the boiling point since the water temperatures never get to 205. It only closes off the open over flow tube, forcing the coolant through the restriction of the radiator tubes. This restriction is what causes the coolant to become low in the radiator. Walt DuPont just posted last week he hasn't added water in a few years using the valve. This allows the coolant to be filled up into the filler neck. The results are more coolant through the radiator and the entire system. More coolant, more movement of water and more air through the radiator all make for better cooling. The valve also acts as a safety valve releasing pressures about 3 lbs. G.M.

GM,
Any chance you have a link to Walt's post?

GM,

Never mind, I found it: https://www.fordbarn.com/forum/showth...11#post1020911 It is hard to argue with success, I think I might try one.

Charlie, There has been many posts like Walt's on here over the years. That would be the first thing I would do to any old Ford with an over flow tube off the top of the radiator. It makes a big difference in cooling and only costs $25.00. G.M.

I made this contraption for my 32 Model B. You only need to check the coolant level ONCE.

Where is the pressure release, I don't see one? Am I missing something?

Your "contraption" is nice looking, but it won't positively ascertain that the coolant level in the radiator is necessarily much higher than the top of the sight glass. By the way, you have to be careful of the orientation of the loop. A pipe loop in a horizontal plane is OK, but a pipe loop in a vertical plane could create an air trap.

The main point of Skip's 3# check valve is to restrict the passage of water OUT of the radiator OVERFLOW tube, thus keeping the coolant level near FULL in the top tank. DD

[tiger.1000]

When the coolant heats up it expands, thus expelling it via the overflow pipe. When it contracts it contracts and settles back to a fixed level. As long as the sight glass is well above the top of the water pump, that's what counts. Purpose of the sight glass is to see where the coolant is. If your motor and water pump, together with your hoses are water tight, believe me, it works a treat !

No pressure release on this old 4 banger...

Where is the over flow tube from the radiator and is it open from the tank to the bottom end of the tube?? G.M.

Radiator overflow tube as per Henry Ford....

Then your contraption looks good but don't do nothing, it's not even a sight glass that provides any valid reading. G.M.

Ok, see what is going on now, it's a sight level tube in addition to the overflow tube. Kinda neat, would be nice if it was higher up so that it indicated radiator fill level.

If you look close he has both the sight glass AND the orig overflow tube.
Sight glass is like on my steam boiler(circa 1920's) that was converted from coal to oil in the late 40's, still going strong.

G.M. It don't do nothing, it does something. What it does is clearly indicate that there is coolant just where it ought to be !

If JS and 1931 can see that, why can't you ?
