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

Crankshaft pulley double belt

Engine Brackets

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

Left-hand Drive

Ecuador

USA Type 1

USA Type 2

Optional Fan

Nissan option flex-fan

Dealer item

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)

Sunny Truck Kit

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

  

• V-belt: 810 or 814 mm

  

• compressor bracket

  

• crank pulley (double V-belt version)

  

• 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

• Engine Mounted 9810- Fast Idle Control Device (FICD)
  • 14875-G5105 Manifold Connector [right next to carb base plate]
    • Vacuum Hose L=370
  • 27654-H8500 FICD Actuator
    • 92551-95W00 Actuator Bracket
  • 27720-G2500 FICD Lever
  • 92255-G5100 Solenoid Valve
    • 92256-95W00 Bracket
    • Vacuum Hose L=270

Vents may be opened or closed:

Twin Condensors and Liquid Tank with connecting pipes.

Condensor-to-Liquid Tank hose is routed along the top of core support.

Compressor is mounted low on left side of engine.

Cooler Unit lines: Evaporator Inlet & Outlet and drain hose

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.
