The Stovebolt Site Forums The Parking Lot '60-'66 Trucks 62 heater arrangement

Hey folks I could use a little help. I picked up my 62 a few years ago and it was not complete so I am a bit confused about the heater situation.

I have a recirculating type heater core and the controls on the dash are two levers. One for the fan ( I assume controls speed) and the other lever controls the flapper in the heater box ( I assume to divert heat to the defroster or to the floor area).

My question is:
In looking at LMC is shows heater control valves for a 62. Would this be for the deluxe heaters. I don't remember having found any of this hardware when the truck came apart. The heater core connections run through the firewall directly to the intake and to the water pump connection.

Without a control valve the heater would run continuously??? Am I mising something??? HELP!!!Thanks!!!!

Hey ChevyD23 that is a good question I have the same two levers in mine as well. When I purchased it it did not have any kind of control in side or outside in one of the hoses to the engine. I do know that my type of heater was a dealer supplied one after purchase of the vehical. I guess to control the heated water or coolant one would have to put a control valve in one of the lines to stop the fluid from reaching the heater core. I have seen such valve on newer vehicals. Well some time in the future I'll find one and install it. Do you have any photo's of your truck? My 63'

My understanding is that deluxe heater has for levers. Two lever is standard

Thanks Hambone, but with only two levers are there no heater control valves?

As shown in the attached 1960 Accessory Installation pages, the economy heater included no shut off valve from the factory. Most of the early installations I have seen used a mechanical valve that turned on and off like a water faucet. This was mounted in one of the heater hoses on the engine side of the firewall. On in the winter, off in the summer.

It’s not uncommon to find a cable operated valve installed either. Any local parts house will have many to choose from, it’s simply a matter of finding a configuration that is most convenient for the setup, and making sure the valve either pushes or pulls to open so it’s plumbed in correctly. A universal choke cable completes the system.

On my truck I use a vacuum operated valve with an electric/vacuum solenoid so I can open or close the valve with the flip of a toggle switch.

Here are the pages from the Accessory Manual:

Markeb,
Wow. All the info I could have ever wanted. Thanks for the help. I will most likely do the manual shutoff as the truck will most likely be a fair weather vehicle for fun.
