Datsun 1200 uses a traditional V-belt to drive the engine accessories. This is commonly called the "fan belt" because it drives the radiator Fan on the Water pump.

Minor Maintenance

USA 1972 Owners manual (see page 35 for fan belt information): Fan belt slackness: 10-15mm

Check the belt slack between the alternator and the fan pulley and adjust it. Grab with finger and thumb and see how far it moves with moderated effort.

Fan belt slackness: 0.394 to 0.591 in (10 to 15 mm)

To adjust the fan belt tension, loosen the Alternator adjusting link bolt and adjust the tension by moving the alternator.
