This 1HZ bare engine is a complete long block assembly built to OEM standards for Toyota vehicles. It is the legendary 4.2‑litre inline‑six naturally aspirated diesel engine known for its exceptional durability and simplicity. The assembly provides a factory‑fresh foundation for your engine swap or rebuild, saving you heavy downtime and expense compared to repairing a worn or seized diesel unit.

Vehicle Compatibility

The 1HZ 4.2L diesel engine powered a range of tough Toyota off‑road vehicles and commercial buses. Always verify your engine code “1HZ” before purchase. Common applications include:

  • Toyota Land Cruiser 70 Series (1990 – present, various body styles)

  • Toyota Coaster bus (1993 – 2016, diesel variants)
  • Other Toyota models or industrial applications originally fitted with the 1HZ engine code

Please confirm your engine code is “1HZ” before ordering. This is a bare engine assembly; all external components must be transferred from your original engine.
