1986 Suzuki Jimny Drive-Belt Pulley — What it does and how to look after it

Based on period technical literature, the 1986 Suzuki Jimny (SJ410/SJ413) does use drive‑belt pulleys. Factory Suzuki SJ410/SJ413 workshop manuals detail V‑belts driving the alternator and water pump from the crankshaft pulley, while the Haynes Suzuki SJ/Samurai manual covers belt adjustment and pulley checks for the same engines (F10A 1.0L and G13A 1.3L). Gates and Dayco application catalogues also list V‑belts for these models and engines, confirming the presence of crank, water pump and alternator pulleys on the 1986 Jimny.

On a 1986 Jimny, the drive‑belt pulley system is old‑school and tough. The crank pulley turns the V‑belt, which spins the water pump and alternator. Some vehicles had dealer‑fit air‑con, which adds another pulley and belt, but most Aussie and Kiwi examples run a single or twin V‑belt set without a separate tensioner. Belt tension is set by pivoting the alternator and locking it up with the correct spanner.

The job of these pulleys is simple: keep coolant flowing and the battery charging. If a pulley’s out of true, rusty, or its grooves are chewed out, the belt can slip. That’s when the dash battery light might flicker, the belt squeals on start‑up, or the temperature needle creeps up in traffic. Some G13 variations use a rubber‑isolated crank pulley
