The Isuzu TFR/TFS, sold between 1989 and 1992, was a staple on New Zealand roads, prized for its rugged simplicity and dependability. This workhorse was ready for anything, from farm duties to daily commutes. If you own one of these classics, keeping it running smoothly requires understanding its quirks and common issues.
Common issues include rust (especially around the cab and chassis), worn suspension components (ball joints, bushings), aging cooling systems (radiator leaks, hose degradation), and potential diesel injector issues on diesel models. Oil leaks from the engine and gearbox are also relatively common as seals age.
WOF tips
WOF inspections will focus on the usual: rust (particularly structural rust), brake performance, steering play, headlight alignment, and tyre condition. Check ball joint play carefully, as these can wear significantly. Ensure all lights are functioning correctly. Also, be aware of any excessive exhaust smoke, which could indicate engine problems or fuel system issues.
