Isuzu C223
2.2 L · inline-4 · naturally aspirated · diesel · 1981–present
Also known as: c223, c223t, c240, 2.2 isuzu diesel
Isuzu's 2.2 diesel — in the Trooper and the Panther.
It is an indirect-injection engine with a mechanical pump and no engine electronics worth the name, which puts it on the far side of every modern diesel line: no rail, no filter, no EGR cooler, nothing to regenerate. Almost every modern diesel complaint is inapplicable here.
What goes wrong is old-diesel wear. Glow plugs and their relay are the commonest cold-start fault and are testable in minutes; injection pump timing drifts as the belt ages and shows as smoke and poor economy rather than as a running fault; and injector nozzles carbon up and knock at idle.
The timing belt drives the injection pump as well as the camshaft, so a belt service is not the job it is on a petrol engine, and getting the pump timing back is the part that takes the skill.
These engines outlive the vehicles around them, and in several markets they are still in service in vehicles far newer than themselves.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
