Mitsubishi 4G52, 4G54, 4G55 engine 2.0L, 2.6L workshop manual

Mitsubishi Astron 4G52 / 4G54 / 4G55 — 2.0L & 2.6L Workshop Manual (Doc No. 30521)

This workshop manual is centered on the Mitsubishi Astron 4G5-series engines and is keyed by engine code first, not by a single vehicle. It’s a compact, engine-focused reference set that groups lubrication, fuel, and cooling alongside the core engine section—useful when your fit decision depends on seeing 4G52 / 4G54 / 4G55 and the matching displacement class.

Engine Set Coverage

• 4G52 — 2.0L
• 4G54 — 2.6L
• 4G55 — 2.0L

Where This Manual Typically Applies

The listing associates these Astron engines with multiple Mitsubishi lines, including Lancer, Galant, Sigma, Delica, Pajero, and Triton. Use the engine code as the primary gate, then treat the vehicle name as a secondary clue for platform context.

Compact technical table

How the Content Is Partitioned

Instead of mixing vehicle systems, the manual stays engine-centric: a main engine section supported by three “support system” chapters (lubrication, fuel, cooling). That layout is most useful when you’re comparing engine codes across different vehicle applications and want the documentation to remain consistent by engine family.

Best-fit Use Case

Choose this set when your engine tag or build data points to 4G52 / 4G54 / 4G55 and you want a single reference that keeps the core engine material adjacent to the supporting system chapters, with the displacement split clearly implied by the engine code grouping.
