Ford Courier: 2.6 petrol (G6) timing and balance-shaft chain rattle from worn guides
2.6 petrol (G6) timing and balance-shaft chain rattle from worn guides is a common engine fault on the Ford Courier on the 1996–2006 cars, and we rate it major. Putting it right costs $800 to $1,800 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 10 documented faults on the Ford Courier.

What you are looking at
Example of the part — not this vehicleThe front of a twin-cam engine with the timing cover off — chain, sprockets and guides.
What goes wrong
The 2.6-litre G6 petrol four drives its camshaft and twin balance shafts by chains, and at this age the guides and tensioners wear, letting the chains slap — a diesel-like rattle from the timing cover at idle that is loudest on cold start. The engine is otherwise one of the tougher parts of the truck, but a slack chain left rattling for years can jump timing and leave the ute running rough or not at all, and by then the price includes recovering a stranded truck. The wear is routine enough that the Australian aftermarket sells dedicated chain, guide and balance-shaft gear kits for the Courier and Bravo G6. Budget a full kit fitted rather than a tensioner alone — worn guides come back.
What you would notice
- Rattle or clatter from the front (fan end) of the engine at idle, loudest when cold
- Rattle rises and falls with engine revs
- Noise persists after an oil change
- Rough running or refusal to start after a long-ignored rattle
How to check it
Where to look. Behind the timing cover at the front of the engine, radiator end
Start the engine cold with the bonnet up and stand at the front of the engine — a petrol Courier should tick over quietly, so a rattly, diesel-like clatter from behind the fan is chain slap, not tappets. Have someone gently raise the revs while you listen: chain noise follows the revs and often flares just as revs drop back to idle. Check the service history for a timing chain kit — on a truck this age an invoice for one is worth real money. If a workshop inspection is possible: have the timing cover area listened to with a stethoscope and the chain slack assessed before purchase.
What it costs to put right
$800 to $1,800 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “Has the timing chain kit (chains, guides, tensioner, balance-shaft gears) ever been replaced?”
- “How long has it had the rattle at idle?”
- “Is there an invoice for any front-of-engine work?”
