Heater position

With the wiper motor position known, next is the heater. I'm decided on a vertical orientation to:
  1. Keep the water pipes on the nearside, where the engine cooling circuit is
  2. Avoid them being level and getting an airlock at the top of the heater
  3. Line up the top pipe sligtly lower than the engine water rail, to hopefully let any air locks naturally out of the heater.
The air intake will take air from the cockpit, inside the car. I can't see the need for an airbox under the bonnet with an open top car.
   although...
If the heater radiator was on the engine side the plumbing would be easier - but it would need an air intake from somewhere....


Just enough room to take the top hoses either side - they will come out just under the dash. The bottom hoses will be above the gearbox and come out of the transmission tunnel just about where the passenger knees/shins are:

 

This is the heater position on the chassis - i.e. when bolted to the scuttle and the scuttle lowered in position. Showing the location of the hot water feed pipe which will have a take-off from the red silicone elbow near the thermostat:


Next up - working out the location for the fusebox & ECU - not much room left in the scuttle space.
