01 / Match your vehicle
Toyota 1HZ engine compatibility
Match the 1HZ 4.2L six-cylinder diesel with mechanical injection, the build details and the original engine specification. The listed years are a guide, not a guarantee for every LandCruiser.
| Vehicle | Listed years | Engine version |
|---|---|---|
| Toyota LandCruiser 70 Series | 1990–2016 listing range | 1HZ · 4.2L diesel · non-turbo |
| 75 / 78 Troop Carrier / 79 Cab Chassis | Confirm original build | Originally fitted with 1HZ; check accessories and configuration |
Other engine codes, models and conversions require a separate fitment check. Send our team your engine details and a photo if you are unsure.
1HZ means non-turbo. Match the original engine.
This listing is for a naturally aspirated 1HZ application. A 1HD-T, 1HD-FT or 1HD-FTE turbo diesel is a different engine. Tell our team about any turbo conversion or other vehicle modifications before ordering. Other LandCruiser series require a separate fitment check.
02 / Plan the engine swap

03 / Quality from the inside out
Take a closer look at your 1HZ replacement.
A new engine foundation
A brand-new long block avoids the previous running history of a used motor. Compare supply, fitting work and warranty when considering a reconditioned alternative.
Match the original specification
Confirm the 1HZ engine code and mechanical injection system before placing your order. Confirm the non-turbo specification and advise us of any vehicle modifications.
Set diesel valve clearances
Your qualified installer must check and set valve clearances and complete the required fitting, commissioning and run-in procedures. This diesel is not hot tested.
Resolve the original fault
Check the cooling, lubrication and fuel systems and inspect the accessories being transferred so an unresolved fault is not carried into the replacement.
04 / Before installation
Plan the job around the whole vehicle.
Find the original cause
Have your workshop diagnose the old engine before replacement. Address any cooling, lubrication or other vehicle-system fault that contributed to the failure.
Check the parts you reuse
Inspect the transferred accessories and check the cooling, fuel and electrical systems as part of the installation plan.
Follow the fitting requirements
Use professional installation and follow the required run-in procedure. Keep the installation invoice and service records for future support.
