What you are looking at

No photograph available

We do not hold a verified photograph of the Timing belt yet. We would rather show none than show a picture of a different part.

What goes wrong

The S170 Crown's 1JZ and 2JZ inline-six engines use a timing belt, and import buyer's guides warn these belts stretch and can snap well before the 100,000 km replacement interval suggests, especially on cars that sat unused in Japan before export. Many imports arrive with no verifiable belt-change history because Japanese service stickers are missed or removed at compliance. These are interference-adjacent designs where a snapped belt at minimum strands the car and can mean a costly engine rebuild. Budget for an immediate belt and water pump change on any S170 without paperwork.

What you would notice

No timing belt service sticker under the bonnet
Faint rattly or slapping noise from the front of the engine at idle
Seller cannot produce any Japanese service history

How to check it

Where to look. Front of the engine, behind the plastic timing cover on the cam belt end

Open the bonnet and look for a Japanese timing belt service sticker (usually on the cam cover or radiator support) showing date and km.
If the odometer reads over 100,000 km, or the car sat in Japan for years, assume the belt is original.
Listen at the front of the engine at idle for slapping or rattling.
Ask the dealer for auction sheet and any service records from Japan.

What it costs to put right

≈A$740 to ≈A$1,470 at independent workshop rates, shown as an approximate guide in Australian dollars. That is for this job on its own, not for the car.

An estimate, converted to Australian dollars, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“Has the timing belt and water pump been replaced since the car landed in Australia?”
“Can you show me the auction sheet or any Japanese service records?”
“Will you discount the price if I have to do the belt straight away?”

Now check the Toyota Crown you are actually looking at

Everything above is true of the model, and it is free. 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.

Which Toyota Crown years are affected?

Our research records this fault on the 2000–2003 Toyota Crown.
