TR6 Disable Heater on a TR6? Good idea?

Is there a way to disable the heater? It seems to be stuck "on" and is blowing hot air on my bare (flip flopped) feet.

I live in the southeast and never need my heater. I almost never drive my TR6 in the cold months anyway.

Are there negative consequences? Other than not having heat, of course.

Thanks for any experience and info
 
Stuck on means a bad or improperly adjusted heater control valve. Disabling the heater will not harm the engines performance. Some people just route the supply hose to the intake. I prefer to block them off so they work the same way a good heater control valve would.
 
It helps to keep the hot water out of the heater core for cooler feet. Many cars don't even have a heater in them. I think Crypty is "sans" heater.

Sometimes, that's all it takes. The valve gets stiff and the cable bends rather than moving the valve. So, with the engine cool, grab the lever on the valve (mounted on the rear of the cylinder head as I recall), and force it closed.

well, that was easy. problem solved. Just did a test run and no hot air at all coming into the cabin.

I thank you. My right foot thanks you.
 
So I guess this means that you don't need the pretty yellow handled heater valve attitude adjustment tool?

Oh, I have one, just didn't need it for this particular "adjustment". /bcforum/images/%%GRAEMLIN_URL%%/hammer.gif
 
One good reason for keeping it cleaned out and hooked up, is that in some cases, it can act as a spare heat sink, absorbing some of the heat that can build up in bumper to bumper traffic. That extra couple of quarts of coolant and a bigger track and additional small "radiator" can come in handy.

It just may keep you from overheating some day, no matter how well your system cools.

Unless you have an auxiliary fan, of course!
