[Roadsters] Heater

[Graeme Suckling]

The list won't see the attached pic. but you should see an "H" stamped 
on the vertical pipe.
When the tap is turned into that vertical position, the heater is 
supplied coolant from the engine.
The pic. shows the tap in the horizontal position.
This position bypasses the heater core.
If you plug that small water connection you will disable the manifold 
coolant circuit as well as the heater.
The manifold is heated to avoid the possibility of the throttle icing up 
in humid climates.
Nothing worse than a throttle plates wide open and iced up, the 
sphincter will react badly!
