2004 Mitsubishi Lancer Timing-Belt-Kit — What It Does and When To Replace

A timing-belt-kit is absolutely relevant for the 2004 Mitsubishi Lancer. Factory documentation for the CH/CS-series Lancer (2002–2007) confirms these models run belt-driven camshafts, not chains. Technical sources such as the Mitsubishi Lancer CH/CS Workshop Manual, Mitsubishi Motors Australia scheduled maintenance guides, and Australian catalogues from Gates and Dayco list a toothed timing belt for common 2004 Lancer petrol engines (including 4G93/4G94 and the 4G63T in Evolution), with recommended replacement intervals around 100,000 km or five years, whichever comes first.

Fitted to the front of the engine, the timing-belt-kit synchronises the camshaft(s) with the crankshaft so valves and pistons keep perfect time. A typical kit for a 2004 Lancer includes the belt, an automatic or spring tensioner, idler pulleys and, in many services, a water pump. Keeping all these parts fresh is vital, a tired bearing or weak tensioner can take out a perfectly good belt. On many Mitsubishi four-cylinder engines of this era, there may also be a separate balance shaft belt, if equipped, it’s smart to replace it together with the main belt.

For everyday Aussie and Kiwi driving, replacing the timing-belt-kit at roughly 100,000 km or five years is the safe bet. Cars that see lots of short trips, high heat, dusty roads, or track work (including Evolution models) may need earlier intervals. Always check for tell-tales like belt cracking, glazing, chirping noises, coolant weeping from the water pump, or oil leaks at the cam/crank seals—oil contamination shortens belt life quickly.

During a timing-belt-kit job on a 2004 Lancer, a good workshop will inspect and usually replace: tensioner and idler bearings, water pump (if driven by the belt), thermostat, cam and crank seals if sweating, drive belts, and coolant. Using quality parts from recognised brands and following the Mitsubishi service procedure (correct alignment marks, tension setting, and two full crank rotations to confirm timing) keeps the engine sweet and reliable.

Done right, a fresh timing-belt-kit turns into cheap insurance against bent valves and a tow bill. It’s a straightforward inclusion in a major service for a 2004 Mitsubishi Lancer and keeps the car ready for the daily commute or the weekend coastal run.

Popular questions about 2004 Mitsubishi Lancer timing-belt-kit

Does the 2004 Mitsubishi Lancer have a timing belt or chain?
The 2004 Lancer uses a timing belt. Factory service information and major belt manufacturers list a toothed belt for the 1.8/2.0 petrol engines and the Evolution 2.0 turbo. Chain-driven Lancers arrived later with the 2007–on CJ models.

How often should the timing-belt-kit be replaced?
Plan on every 100,000 km or five years, whichever happens first. If the car sees hot climates, lots of stop–start, dusty conditions, or you’ve got an Evo driven enthusiastically, shorten the interval. Age hardens rubber, so time matters even on low-kilometre cars.

What else should be changed with the belt?
At minimum: belt, tensioner, and idlers. Many owners also replace the water pump, thermostat, accessory belts, and any weeping cam/crank seals. If the engine has a separate balance shaft belt, replace it at the same time for peace of mind.
