Land Rover Series III 2.25 diesel: injector test & service

Fuel & air · Series III (1971–85) · 1971–1985

How often: every 24,000 mi or 2 yrs, whichever comes first. Worn injectors cause smoke, knocking and hard starting.

Work safely: support the vehicle on axle stands, never a jack alone; let it cool first. Check figures against your workshop manual. You do this work at your own risk.

Parts

4 × Injector washers & seals
4 × Injector test & reset (specialist, if needed) (specialist)

Tools

Spanners
Injector puller if seized

Step by step

Clean around each injector before you remove it.
Remove the injectors and send them to a diesel specialist to test spray pattern and set the opening pressure.
Refit with new copper washers and heat-shield seals. Bleed the system and check for leaks.
