Is there any way to turn off a heater during the summer, ie close some valves or something?

If your heater valve, the one that controls cabin temperature is broken, like mine, until I get it fixed, I took the hose that ran from the water pump to the heater core, off at the heater, and connected it to the other port on the engine. And then I looped the other hose on the heater core so that there were no open ports. You will loose a little coolant when you disconnect the hoses. If you would like pictures of what I did on my 49, send me a PM with your e-mail address, and I'll take a couple and send them to you

I believe that the valve Canadiandelux is referring to is the Ranco thermal valve which would be applicable to post-war cars. drjrharris has a pre-war car (1941 110 I think). For the pre-war cars there was often a turn-off valve installed at the end of the rubber hose as it enters the engine head. The heaters in the pre-war cars were installed as a self-contained box with heater core and fan attached to the firewall unlike the much more integrated fresh air/heat systems post war.

Here's an example of a heater valve on a pre-war car.

Yes, I am refering to the Ranco valve. I didn't know drjrharris had a pre-war. My appologize drjrharris, I should have asked.
