Parts for your 2019 Mitsubishi Outlander-Timing belt kit

2019 Mitsubishi Outlander timing-belt-kit: do you need one?

For most 2019 Mitsubishi Outlander variants, a timing-belt-kit isn’t relevant because they run a timing chain, not a belt. Technical references including Mitsubishi Motors service manuals and the 2019 Outlander maintenance schedule for AU/NZ list timing chains on the 2.0L and 2.4L petrol (4B11/4B12), the PHEV’s 2.0L petrol, and the 2.2L turbo-diesel (4N14). Aftermarket catalogues from Gates and Dayco also align with this, showing no timing belt listing for those engines. However, the 3.0L V6 (6B31) offered in some 2019 trims does use a timing belt, and those engines take a timing-belt-kit per Gates/Dayco application guides and the Mitsubishi 6B31 service manual.

• 2.0L/2.4L petrol and PHEV: timing chain (no timing-belt-kit used)
• 2.2L diesel: timing chain (no timing-belt-kit used)
• 3.0L V6 (6B31): timing belt (timing-belt-kit required for scheduled replacement)

Why most 2019 Outlanders don’t use a timing-belt-kit: Mitsubishi’s chain-driven engines are designed for service life without routine belt changes. Chains are lubricated internally and generally inspected rather than replaced at fixed intervals, which is why the official maintenance schedule doesn’t call up a timing belt for those engines.

If your 2019 Outlander is the 3.0L V6, a timing-belt-kit absolutely applies. A kit typically bundles the belt, hydraulic or mechanical tensioner, idler pulleys, and often a water pump and seals. It’s fitted to synchronise the crankshaft and camshafts precisely, keeping valve timing spot on for power, efficiency, and emissions. Over time, the belt and rotating hardware wear from heat cycles and load, the kit approach ensures all interdependent parts are refreshed together so a new belt isn’t relying on a tired tensioner or noisy idler.

Replacement timing: check your owner’s handbook and local schedule, but AU/NZ guides and parts catalogues commonly indicate around 100,000–120,000 km or about 5–7 years for the 6B31 V6. Many workshops recommend doing the water pump, thermostat, accessory belts and coolant at the same time because labour overlaps the same area. Genuine or OEM-equivalent parts from recognised suppliers (Mitsubishi, Gates, Dayco) are the safe bet.

Warning signs before the due interval can include belt glazing/cracking, chirps or whirrs from the front of the engine, coolant seep at the pump, or erratic idle from timing drift. Because the 6B31 is an interference design, a failed belt can cause serious internal damage. Sticking to the interval and using the full kit is cheap insurance. Have a qualified technician handle the job with the correct locking tools and torque procedures as specified in the Mitsubishi 6B31 service manual.

Popular questions

Does a 2019 Mitsubishi Outlander have a timing belt or chain?
Most 2019 Outlanders (2.0L, 2.4L, PHEV, and 2.2L diesel) use a timing chain and don’t need a timing-belt-kit. The 3.0L V6 (6B31) uses a timing belt and does require periodic belt kit replacement, as noted in Mitsubishi service information and parts catalogues.

When should the timing belt be replaced on the 3.0L V6 Outlander?
Common guidance for AU/NZ is roughly 100,000–120,000 km or 5–7 years, whichever comes first. Always verify with the owner’s manual and the workshop’s access to Mitsubishi’s latest maintenance schedule. If there’s any noise from pulleys or signs of coolant seepage, bring the job forward.

Should the water pump be replaced with the timing belt?
Yes, it’s good practice. The water pump is driven off the timing belt on the V6, and the extra labour later far outweighs the small parts cost now. Most reputable timing-belt-kits include the pump, gaskets, and fresh tensioners/idlers to keep everything reliable for the next service interval.
