holden rodeo 3.6 v6 engine problems

The Holden Rodeo 3.6 V6 (Alloytec) can be stout if serviced, but it does have a few party tricks you’d rather it left at home. Here are the usual suspects to watch:

• Timing chain stretch and guide wear causing cold-start rattle and fault codes (P0008/P0009/P0016).
• Oil leaks from the timing cover and rear main seal.
• Ignition coil and plug failures, rough idle or misfire; fouled throttle body/MAF sensors.
• Cooling-system woes: tired water pump/thermostat or clogged radiator leading to heat soak under load.
• Cam phaser/actuator issues and the occasional check engine light.
• Thirsty fuel use, especially with autos or towing.

Before you buy: listen for chain rattle on a cold start, scan for timing correlation codes, check for leaks, and take a long uphill drive to see if temps behave. Preventive care helps: quality synthetic oil changes every 10,000 km, cooling refresh every 2 years, and budget roughly AUD 1,500–3,000 for a full timing-chain kit if needed. A thorough pre-purchase inspection by someone who knows these engines is worth its weight in unleaded.
