Hi Kreg,
Not having my Sunbeam in front of me to check, I would guess the heater
valve may be installed incorrectly. Although it seems like not enough
coolant to overheat the car, I would check this first.

Iv'e been driving a different Sunbeam , actually a Tiger, but I still have
the
Series V,the past two days that I do not know the history of but it has
had a
rebuild of late on the engine and everything seems fine except- When I
slide
the heater control from off over to hot to use the heater or defroster the
engine temp guage jumps up like a rocket. The engine temp is fine until I
slide the heater control from "0ff".
I always thought that if your engine was overheating you should turn the
heater on - that is to say open the heater control valve. This is just the
opposite. Since this a new car to me I was wondering if anyone had a guess
where to start to diagnose this situation. I can drive around all day with
no
overheating otherwise. Maybe the thermostat is in backwards or something.
I
am stumped- but it is not the first time.
?????
