2006 Holden Commodore Repair Question
Holden Commodore Coolant Problem
Check the oil level, and check for white smoke from the tail pipe. If no signs are found there, consider adding a small bottle of dark purple dye to the coolant. Later, when the level has gone done again, search with a black light. The dye will show up as a bright yellow stain that you can follow back to the source.
