Parts for your 1998 Mitsubishi Lancer-Drive belt tensioner

1998 Mitsubishi Lancer drive-belt tensioner — is it actually there?

Short answer: no, a spring-loaded accessory drive-belt tensioner isn’t used on the 1998 Mitsubishi Lancer (CE series). Technical sources including the Mitsubishi Lancer CE Workshop Manual (1996–2003), the Dayco Australia vehicle application catalogue, the Gates DriveAlign/Micro-V catalogue, and the Haynes Mirage/Lancer manual all show that the CE’s accessory belts are tensioned manually via the alternator and power-steering pump adjusters (and, on some variants, an adjustable idler), not by an automatic serpentine tensioner. The only tensioner on these engines is for the timing belt, which is a separate system altogether.

Why it’s not used comes down to the era and design. The 4G15 (1.5L) and 4G93 (1.8L) engines in the CE Lancer run individual multi‑rib belts for the alternator/water pump and for the A/C or power steering. Belt tension is set by loosening the pivot and lock bolts on the alternator or pump, turning an adjuster screw to set tension, and then tightening everything back up. That approach was common in the late 90s and keeps parts count and cost low, especially on compact cars.

What should owners service instead? Focus on belt condition and correct tension. An “automatic tensioner” isn’t something that needs replacing because it isn’t fitted, instead, plan periodic checks and adjustment:

• Inspect belts for glazing, fraying, cracking, missing ribs, and oil contamination.
• Listen for cold-start squeal, chirps on steering lock, or flickering charge lights — all hint at slack or worn belts.
• Check and adjust belt tension at service intervals or anytime a belt is replaced, recheck after a few hundred kilometres as new belts bed in.
• Spin idler pulleys (if fitted) and the alternator/PS pulleys by hand — any roughness or play means replacement is due.

A quick adjustment tip: under the bonnet, loosen the alternator or power-steering pivot and lock bolts, use the adjuster bolt to set tension so the belt twists about 90 degrees at mid‑span by hand pressure, then re‑tighten. Don’t overtighten — that can load up bearings and lead to early alternator or pump failure. Most workshop guides recommend replacing accessory belts every few years or around the typical service life window, especially in hot or dusty conditions common across Australia and New Zealand.

Technical sources referenced: Mitsubishi Motors Lancer CE Series Workshop Manual (Engine and Electrical sections), Dayco Australia vehicle application catalogue for Lancer CE 4G15/4G93, Gates Australia Micro‑V/DriveAlign catalogue, Haynes Mitsubishi Mirage & Lancer Repair Manual (late 90s–early 2000s). These publications describe manual belt adjustment for the CE and list no automatic accessory-belt tensioner.

Popular questions

Does a 1998 Mitsubishi Lancer have a drive-belt tensioner?
It doesn’t use a spring-loaded serpentine tensioner. The accessory belts are manually tensioned using the alternator and power‑steering adjuster brackets (and an adjustable idler on some variants). The only tensioner you’ll find is on the timing belt, which is unrelated to the accessory drive.

How are the belts tensioned on a 1998 Lancer?
By loosening the pivot and lock bolts on the alternator or power‑steering pump, turning the adjuster screw to set belt tension, and re‑tightening. After any new belt is fitted, the tension should be rechecked once it’s bedded in over a few hundred kilometres.

What symptoms mean the belts need attention on a CE Lancer?
Squeals or chirps on start‑up, heavy steering under load, dimming or a battery light at idle, and visible cracking or glazing on the belt ribs. If any of these crop up, inspect condition and tension and replace worn belts or rough idler pulleys.
