62 heater box mixer valve?


Pondering what hoses and from where go to this heater box.. I can understand the normal heat exchanger ones, but there are two more hose connections on the top there and it looks to be a valve... What's that for? Round black gadget.

Man, I was hoping someone could help you by now. I know we have some 62 owners here.

Guys?

The little black thing is a heater control valve used in 61-62 for sure, not sure about other years. It opens and closes via the heater controls in the car.

This is how it is set up in my 61 with a 261. I don't imagine it would be any different in 62 because its the same valve.

Hose from the water pump to the top inlet on the heat core.
Hose from the bottom inlet on the heater core to the passenger side of the heater control valve.
Hose from the driver side of the heater control valve back to the engine.

Hope that helps!

ok, in the meantime, Ive figured out what that valve does..... there are two diff size hose connections on the heater core itself... and same on the engine.
the water pump connection is larger (3/4) and the smaller one is up by the thermostat.
where the water pump connection is looks to me like it's cold coolant coming from the bottom of the rad... it's right alongside the large hose, and correct me if i'm wrong but cold coolant comes from the lower rad hose.

So, my thinking was that the hot coolant from the head, (just below the thermostat) should head towards the valve - not sure which side of that valve - but coming out of the valve it short loops down to the heater core, then the large hose out of the heater core back to the "intake" of the water pump.

qyestion, does the water pump push coolant into the engine block, or suck it out?

I hooked it up this way and it works, I do get warm air (excited for fall cruising!) but I m always looking to verify the right way!
cheers.

I have pics of 3 62 Chevys with that setup, a 235-6, a 327, and a 283. The hookup on all 3 are different. A 4th 62 which was a 235-6 when new and had that valve on top of the heater missing. Seems it doesn't matter much. All 3 are Canadian Chevys.

In the Chevy shop manual, the "deluxe heater" has the hoses hooked up like this. If you number the 4 hoses clockwise, #1 being the top left one, #1 hooks directly to #3. # 2 and # 4, the drawing in the manual doesn't show where they go, but they are different diameters as are the 2 hoses that hook to the water pump/block, so hook them to the correct sizes. I think it is #2 to the top/block and #4 to the bottom/water pump.

In my 62 Cdn Chev shop manual supplement, it says the deluxe heater was standard in 62, likely the same in a Cdn Pontiac. In 61, it was optional.

Here is my 61 Bubbletop. It will be the same. I don't have that balance fitting but I think that's a 62 only thing but I could be wrong. Yes I know the fuel lines are terrible. No it's not a real 348 car. All Canadian built cars by this time had deluxe heaters and standard equipment.
