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.

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