Parts for your 1990 Suzuki Jimny-Drive belt

1990 Suzuki Jimny drive-belt — what it does and how to look after it

Yes, a drive-belt is absolutely used on the 1990 Suzuki Jimny. Factory workshop literature for the SJ413 and JA11 (e.g., Suzuki Service Manual P/N 99500-83A00-01E and 99500-81A50) and major parts catalogues from Gates and Dayco list accessory V-belts for these models and engines (G13A/G13BA and F6A), confirming the belt drives key ancillaries. It’s often called the fan belt or accessory belt.

On a 1990 Jimny, the drive-belt spins the alternator to keep the battery charged, turns the water pump for engine cooling, and—on many variants—also drives a mechanical fan. If fitted with air-con and/or power steering, there’s typically an additional V-belt for those accessories. Without a healthy belt, the charge light can glow, the temperature can climb, and a great little 4x4 trip can turn pear-shaped fast.

Given Aussie and Kiwi conditions—heat, corrugations, creek crossings, beach runs with salty air—the belt cops a tough life. The smart move is to inspect at every service (roughly every 10,000–15,000 kilometres or 6–12 months). Look for cracking, glazing, frayed edges, missing ribs (if multi-rib), or squeals on cold start. Keep an ear out for chirps after a dunking or mud run, and check tension: a belt that twists more than about 90 degrees by hand is likely too loose, one that’s guitar-string tight can hammer bearings.

Replacement intervals vary by brand and use, but a practical rule is every 60,000–100,000 kilometres or 4–6 years, sooner if there’s noise, slippage, contamination, or visible damage. When replacing, always match the belt to your engine and accessory setup—1990 Jimnys can run one or two V-belts depending on whether AC/PS is fitted.

• Note the routing before removal (snap a pic under the bonnet).
• Disconnect the battery and mind the fan blades.
• Inspect pulley grooves and alignment, clean off mud and oil.
• Set correct tension, run the engine, then recheck and retension if needed.

Worth a quick reminder: many 1990 Jimnys with the G13 engine also use a separate timing belt (cambelt) inside the front cover—different job, different interval. The accessory drive-belt discussed here is the external one running the alternator, water pump, and fan.

How often should the drive-belt be replaced on a 1990 Jimny?

As a guide, plan for 60,000–100,000 kilometres or 4–6 years, but condition and use matter more than the calendar. If it’s noisy, slipping, cracked, or soaked in oil/coolant, replace it straight away. Harsh off-road use, heat, and sand can shorten the interval.

Does a 1990 Jimny run one belt or multiple belts?

Most run a main V-belt for the alternator/water pump/fan. If the vehicle has factory air-con or power steering, expect a second V-belt. Check your specific pulley layout before ordering parts.

What belt do I need for my 1990 Jimny?

It depends on engine code (e.g., G13A/G13BA or F6A) and whether AC/PS is fitted. The safest bet is to check the old belt’s size, measure its effective length, or consult a belt catalogue using your VIN and accessory setup.
