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. They are fairly common on late model B122 Sunny Trucks.

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

  • condensor (before radiator, radiator horizontal)
  • capacitor for electric fans
  • high-pressure pipe
  • low-pressure hose
  • Receiver tank
  • relay harnesses
