Thank you, man. I think the single speed will be fine too. I think when I put put radio back in over the summer I pulled out the plug for the fan, so now I have a zero speed! LOL! I'll fix that in the morning!

Thank you, Ken. I'll definitely keep an eye out for leaks. Good to know!

Bill,
You may not need a 2-speed blower to blow more heated air into the car.
Many multiple speed blower motors simply use a resistor to reduce the speed of the motor to reduce the flow of the air. A 1-speed motor won't have this resistance so it will operate in full speed mode.
What is your electrical system, 6V or 12V?
C&G offers blower motors for both electrical systems.

Bill,
Glad you got it working. The diagram is correct on how the water flows.
Check carefully upon startup to make sure the valve is not leaking. They sometimes do after being stuck.
You should be fine with a single speed blower. Not real sure how the speed works on a '51. On the '50, the motor is a single speed, but a rheostat on the switch controls the speed - creates two speeds.

Well i got it all apart today and the valve works; it was just stuck. A little PB Blaster and some Marvell Mystery oil and it moves like new! So, now I have another question. If you look at the jpg I attached, the hot water comes from the passenger side head into the valve and if the valve is open, it then flows through the heater core and back to the water pump, is that how the water flows? My '51 has a single speed blower. I think it's off an early Mustang. It seems to work with ^V positive ground, I mean I hear it working, do I need the two speed to blow some heat? Who makes a good two speed blower motor I can use.
As always,
Thank you guys.
Bill

There is also a relevant post on this from just a couple of years ago on the Fordbarn. https://www.fordbarn.com/forum/showthread.php?t=324716
Member Shoebox posted: "I hear there are those that have done it, but the process seems rather tedious, just bending the tabs that hold it together without breaking them is an example. I had my control valve rebuilt by Shoebox Central and in talking to them I learned they have a fixture and special tool(s). They did an awesome job."

Bill,
Chris at Shoebox Central worked for Ray Marler at Shoebox Ford years ago. I'm sure Chris was taught the process by Ray.
Ray rebuilt the leaking Ranco valve on my '50 Convertible when I restored it in 2002. Still working just fine to this day.

Kens 36, Thank you! Shoebox looks like the way to go for me! This car is a total labor of love for me. I've spent hundreds of hours under the car and under its hood. Not one minute of that time has ever felt like work.

Carcrazy: Thank you! that's an interesting alternative! Let me see how far I get with the valve.

Bill,
I would not hesitate to have the valve rebuilt by Shoebox Central - they know what they are doing.
To remove it, there are no springs to fly out. Just a little bit of coolant. It is well worth it to have your heater working correctly.
My apologies to nelsb, but we don't all live in the permanent summer weather of Minnesota.
