Datsun 1200, unlike the Datsun 1000, was designed with air conditioning in mind. However, it was still a dealer-installed add-on option and so varied by country and region. In April 1978 it became a factory option for Japanese market Sunny Truck. The interior cooler protrudes into the passenger legroom and precludes using a package tray.

Parts Needed

  • Pump
  • Condensor (cooling radiator)
  • Double crankshaft pulley. (The extra pulley runs the compressor)
  • Under-dash vents
  • Hoses
  • Wiring

Since B110 A/C is fairly rare, you can source most of the parts from a B210 or B310. Only the interior vent setup is needed for a B110.

Compressor

The compressor pump bolts to the engine and is driven by a v-belt

Engine Brackets

Various types were used. Early A12 and late A12 brackets differ. There were several versions of each.

From USA catalog:

  • 21060-H1001 FAN-COOLING A12 (standard B110 fan)
  • 21060-A4605, 21060-N0100 FAN-COOLING D=330 FOR TROPICAL USA (330 mm diameter)

B122 Sunny Truck Kit

20078.jpg
This kit is beautiful and easy to install. Unfortunately the interior cooler unit is bulky and protrudes farther into the passenger legroom than other types.

You need all these parts:

  • Ass'y indoor "cooler unit" (with integrated air volume switch, evaporator, and blower fan)

  • air conditioner compressor
    20084.jpg 20085.jpg
  • V-belt: 810 or 814 mm
    20088.jpg 20089.jpg
  • compressor bracket
    20079.jpg
  • crank pulley (double V-belt version)
    20080.jpg
  • Twin Condensors (before radiator, radiator horizontal)
    One has an electric fan
    • Pipe connecting twin condensors
  • High-pressure flexible pipe (from compressor to condensor)
  • Low-pressure hose (from evaporator to compressor)
  • Tube-Liquid Tank to Evaporator
  • Liquid Tank
    • Bracket to mount Tank on core support
  • Receiver tank (Liquid tank)
  • Relay (for compressor)
  • Wiring harness
  • Capacitor for electric fan

Vents may be opened or closed:

Legroom

Since the cooler unit takes up some of the passenger legroom, what to do? One enterprising 1200 fan mounted the cooler unit in the dash:

Of course the downside is there is no glove box.
