Parts for your 1987 Suzuki Swift-Drive belt

1987 Suzuki Swift drive-belt: what it does and how to look after it

Based on the Suzuki Swift (SA/AA, 1983–1988) factory service information, the Haynes Suzuki Swift 1985–2000 manual, and belt application catalogues from Gates and Dayco, the 1987 Suzuki Swift is fitted with accessory drive-belts (traditional V-belts) for the alternator and, where equipped, air-conditioning and power steering. The camshaft and water pump are driven by a separate timing belt on these G-series engines, so the accessory drive-belt is very much relevant for this model.

On this classic Swift, the drive-belt’s job is simple and crucial: it spins the alternator to keep the battery charged and the electrics happy, and it may also run the A/C compressor and power steering pump on cars fitted with those options. Without a healthy belt, you’ll cop squeals under the bonnet, a glowing battery light, flat batteries, and poor accessory performance.

For routine servicing, it’s smart to inspect the belt at every service interval. Look for cracking across the ribs, glazing or a polished sheen, frayed edges, and rubber dust around the pulleys. Give it a quick twist, if it’s hardened or feels overly slack, it’s time for attention. On a correctly tensioned V-belt, expect about a centimetre of deflection at the longest free span with moderate thumb pressure. Too tight will flog out alternator bearings, too loose will slip and squeal.

Replacement is straightforward on most 1987 Swift variants:

• Loosen the alternator pivot and adjuster bolts.
• Swing the alternator in to relieve tension and slip the old belt off.
• Fit the new belt, align it in the pulley grooves, then tension to achieve that small mid-span deflection.
• Re-tighten the bolts and recheck tension after a short drive as new belts can bed in.

As a rule of thumb in Aussie and Kiwi conditions, inspect every 10,000–15,000 kilometres or 6–12 months, and replace the belt every 60,000–80,000 kilometres or 4–5 years, or sooner if there are any signs of wear or noise. If the car has multiple belts (e.g., separate A/C belt), treat each the same way. And don’t mix up the accessory drive-belt with the timing belt—different job, different interval—though it’s convenient to check both while you’re there.

Quality belts from reputable brands that list the 1987 Swift in their catalogues will match the correct length and profile for either non-A/C or A/C setups, keeping this light, efficient hatch running sweet.

• Does the 1987 Suzuki Swift use a serpentine belt?
  No. It uses one or more traditional V-belts for the alternator and optional A/C and power steering. Later cars moved to serpentine layouts, but this generation sticks with simple V-belts.
• How often should the drive-belt be replaced on a 1987 Swift?
  Check it every service (about 10,000–15,000 km or 6–12 months) and replace around 60,000–80,000 km or 4–5 years, or immediately if it’s cracked, glazed, noisy, or leaving rubber dust.
• What are the signs the belt needs attention?
  Squealing on start-up, a battery warning light, visible cracking or frayed edges, a shiny glazed surface, or noticeable slack. Any of these are a cue to adjust or replace the belt.
