Heater Rebuild
I just bought a 1966 F250 4x4. The heater doesn't close so heat is blowing all the time. How difficult are the heaters to rebuild? Any where to send off to have them rebuilt? Where do you recommend I buy the parts if I rebuild myself? Thanks.

Which heater do you have? Are there two cables mounted to a bracket under the dash to the right of the steering column?

Ive actually been working on mine as time alows. Pretty easy to get apart. Some drilling of the old rivets is a bit of a pain in the butt.
You can buy new motors, squirrel cage, heater cores, foam pads, cables, and the resistor. Chances are your squirrel cage is OK. Chances are you need to pull it apart, check to see if you have any critters living in there and or clean out their nest. You can clean the heater core with acid or replace it for like $35.
I have a bunch of pics, just have not uploaded them to my photo album yet. Mine needs a little bit of fiberglass work as well. My motor is OK. Core was cleaned with a mild solution of acid. Need a new resistor, and foam pads for the core.

As masked rider says.... remember the heat is shut off by completely shutting off water supply to the heater, the temperature valve in the heater hose line has to be adusted to allow full shut off and it should be in the line from the water pump to the heater. Those darn valves are expensive for what they are, they can usually be cleaned by soaking in CLR, rinsed then soaked in a rust remover or use electrolosis to remove the rust and crud. Negative battery post to part, positive to a piece of iron, in a bath of 1/4 cup baking or laundry soda in 1 gallon of water.

The valve used with the Economy fresh air heater is manually operated (C5TZ-18495-A).
Deluxe fresh air heater has two cables mounted under the dash to a bracket. One of these cables attaches to the heater water valve (C3UZ-18495-A), there's no adjustment.
This valve is notorious for getting stuck closed/open or partially. The good news is, it's available from Ford, the manual valve is obsolete, but a few are available NOS

"adjusting the valve" means installing it properly. Install valve, shut by hand, push temperature cable **** all the way in, attach end of cable to valve such that it is fully shut, test for ease of opening and shutting, if you pinch the attachment clamp too tight, it will not open and close easily.

Should be able to get this from Home Depot, plug it inline a couple clamps and you are in business for $10.00, a plastic one for less than $5.00.

Just make sure you install the shut-off valve on the correct hose leading into the heater core. Some will say it doesn't matter BUT it does. Two heater hoses come off the engine. One is a pump hose and the other is a return hose. Make sure you install the valve on the pump hose and in the proper location so the cable attaches correctly... It you install the heater valve on the return hose, you WILL still get hot water that radiates through the heater core and will still have warm or even hot air coming off the heater core. Maybe not a lot but than again it depends on what state you live in. If your in a hot state,,, ANYTHING will add to temps inside the cab... ;O(
If you still do not understand what I'm trying to say,,, PLEASE feel free to ask. If I don't get back to you, I'm sure someone here will. There are plenty of guys here that now exactly what I'm saying.... Good Luck
