There should be a valve on the block which allows the
coolant to flow through the heater.  You should be able
to trace the heater hoses to find it.  You may find that
although you have the control on the dash set to cold
that this valve is stuck 'open' and still allowing hot
coolant to flow through the heater system.

This happened to mine, but stuck in the closed position
so I wasn't getting any heating. Some lubrication and
manual operation opening and closing should free it up.

Good Friday morning . . . .

Even though I realize the engine transfers considerable heat to the
cockpit (especially in the GT), I suspect my heater may be "on" all the
time.  The fan's not running, but I'm curious about the heater element.
How would I check this out?

Thanks for the advice in advance - Gary Davis
