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 2.5 and 2.7 V6s (H25A/H27A) run three timing chains and tensioners, and cold-start rattle from a failing number 1 tensioner is so well documented that an AERA technical bulletin covers 1999-2002 engines; the same design carried into 2005-2008 2.7 XL-7/Grand Vitara models. Suzuki initially specified replacing tensioner 1 only, then revised the bulletin (in Canada) to include chains and sprockets if worn, because tensioner-only fixes did not last. It is an interference engine and the front of the engine must come apart - the flat rate is over 8 hours - so a rattling V6 is a major cost.
What you would notice
- Rattle from behind the timing cover, loudest cold
- Rattle fades as oil pressure builds, returns each morning
- Whirring/slapping at idle on worn chains
How to check it
Where to look. Timing chains behind the front engine cover
Cold start is everything: arrive early, confirm the engine is stone cold, start it and listen at the front of the engine for chain rattle in the first 30 seconds. Walk away or price in a full chain kit if you hear it. Ask for receipts if the seller claims chains were done.
What it costs to put right
≈A$1,840 to ≈A$4,140 at independent workshop rates, shown as an approximate guide in Australian dollars. That is for this job on its own, not for the car.
Ask the seller
- “Have the timing chains and tensioners ever been replaced - receipts?”
- “Does it rattle on the first start of the day?”

What it does not tell you is whether THIS car still has money owing on it, has been written off or reported stolen, what kms it showed in past sale ads, whether it has had accident repair claims and what it is worth today. That comes from the official records for that plate. Enter the plate and its state for the A$17.90 Vehicle Check, or the full history from A$24.99.
