2.6L (G6) Petrol - DX/Workhorse
Petrol
Listen carefully for any ticking or tapping noises from the top of the engine while idling, as high-mileage G6 engines may develop valve train wear over time.
Shift through all gears, including reverse, while moving slowly to ensure the manual transmission engagement is smooth and free from grinding or 'popping out' of gear.
Check the cooling system by inspecting the overflow tank for oil residue and monitoring the temperature gauge during a longer climb, as cooling efficiency can diminish on older workhorses.
Inspect the chassis rails and inner guards for any signs of heavy corrosion or past rust repairs, which is something to be mindful of given the age of the UN series.
Usually marks the point where suspension bushings and ball joints may start showing signs of fatigue.
Often the period where the original alternator or starter motor might require a professional inspection.
Typically a stage where the internal condition of the differential and manual gearbox seals should be monitored for minor weeping.
Prioritize regular oil and filter changes every 5,000 to 7,000km to keep the G6 engine running happily.
Keep a friendly eye on the spark plugs and ignition leads, as a fresh set can do wonders for the engine's fuel efficiency.
Ensure the cooling system is flushed periodically, as keeping the radiator clear helps maintain consistent operating temperatures.
Check the condition of the brake fluid levels and pad thickness to ensure your stopping power remains consistent.
Periodically grease the driveshaft and suspension points to keep the ride feeling compliant and quiet.
Estimated repair costs if issues arise
If the bite point feels very high or if there is slipping under load, you might eventually need to budget for a clutch kit replacement to keep your gear changes crisp.
Because these vehicles often worked hard, the shocks and leaf spring bushes might reach their service limit; it is wise to set aside funds to restore that factory-like handling.
If this component needs attention in the future, replacing the radiator and hoses helps prevent overheating, which is vital for the longevity of the 2.6L engine.
