70,000 k service and I have been advised the clutch is cactus. Now my last 4x4 was the last of the Isuzu powered Colorado's and it's clutch went to god after 72,000 ks. Is it me? Clutch Industries in Melbourne told me that there was issues with most new common rail diesels clutchs. Was shocked when Isuzu agreed to replace under warranty. Holden wouldn't.
