- Possible cause described
- CarsGuide (2023) explains that these diesels were under-cooled and are notorious for overheating, and advises against driving them with the throttle flat to the floor; the Trade Me guide also lists overheating as a weak point. Several owners report cracked heads or failed gaskets and having had to replace the whole head; overheating usually ends in a damaged head.
- Check for the garage
- Ask for a chemical combustion-gas test on the coolant or a cylinder leak-down test; check the radiator is clean and unobstructed (bull bars, spotlights); watch the temperature on a long climb.
