On a '65, you have the 3 levers that control heat. How should the levers be set for summer time? in other words, when you dont want the heat up. I dont have a manual with me, and i dont remember how to set them for no heat. Thanks!

Can't answer that question but it reminds me of what I did to survive Texas summers in my daily driver. AC equiped cars came with a vacuum actuated vallve that shut off the water flow to the heater core. The way I saw it I did not want the 200 degree water anywhere other than the engine compartment, that allowed to to run the vents and only blow the 100 degree outside air

Set heat control to cool/off
set flow control to Fresh, will allow air in to cabin area.
third is fan speed.

Isn't that 69' specific PA? I thought none of it was labeled externally in 65'.

Could be, It works that way on the 68 cougar.
If there is a fresh air vent on the heater box open it.
there must be some way to get air inside.

Most '65s don't have a control valve on the heater hose, it just runs thru all the time. My '65 has dealer installed A/C and didn't have one, not to say it never did, but I didn't see any provisions from where one used to be. I had a nipple on my hose that was spliced in about the front of the valve cover. I'd disconnect one hose from the water pump and at this nipple (nipple stayed on hose to heater coil) the long hose connected to the nipple and the short one looped back to the water pump.

On a stock 67 with factory AC the valve was activated when you threw the switch that engaged the compressor. When I had mine rigged (on a non-AC equipped car) it was just connected to constant vacuum by me manually in the engine compartment. I usually connected it in early April and disconnected it in late October, times when I knew I would not need the heater.

Something else you guys can do if you dont want to fool with taking the hoses on and off. You can get a manual cutoff valve (Napa # 660-1414) thats for 5/8" heater hose and put those in both hoses. Then just turn them off and no more hot water coming inside. We do this on RV's because the dash air's dont cool real good here in Texas.....

My 67 coupe's heater controls are all in the up position when turned off. The fresh air inlets are the knob on the left side of the steering column and the heater box door on the passenger side, of course with full length headers, it really doesn't matter .

For '65-'66 the heater control knobs should all be in the up position (off).
