Does my Prado have a timing belt?
| Sold | What the sources say | |
|---|---|---|
| 4.0-litre V6 petrol | J120 and J150 Prado | Timing chain. CarsGuide says it should be good for the life of the vehicle |
| 3.0-litre turbo-diesel | To June 2015 | Go by the service book |
| 2.8-litre turbo-diesel | June 2015 on | Wikipedia lists a chain drive, while a CarsGuide answer on a 2020 Prado says belt |
What to do about the diesel
That table's disagreement is real. CarsGuide's answer on a 2020 Prado says the turbo-diesel's belt needs replacing at 150,000 km or five years, whichever comes first. Wikipedia lists the same year's 1GD-FTV engine with a chain. So don't take either as your answer, us included.
Open the Warranty and Service Book and look for a timing belt line in the schedule. Then ask the mechanic to confirm it on the car itself. If the book does call for a belt and there's no record of it, treat it as due. A timing belt (the rubber belt keeping the valves in step) can do a lot of damage if it fails. Our timing belt or chain guide explains why.
Toyota Prado problems on record
Piston cracking on the 3.0-litre diesel. CarsGuide says it affected Prados from 2009 to 2014, most commonly at something like 100,000 km or 150,000 km. Toyota issued a service bulletin, and no recall. If you're looking at one of these, ask for the service history and whether that work's been done.
DPF on the 2.8. Diesel Prados fitted with a diesel particulate filter (the part that catches soot in the exhaust) and bought between October 2015 and April 2020 are known for DPF trouble. Look out for the DPF light returning again and again, or the car feeling flat. RACQ says low-speed, stop-start running is the most common cause, so tell the mechanic how the Prado gets used. They should read the codes and find the cause before anyone talks about a new filter. Ask Toyota or a mechanic to run your VIN for any program or recall that applies, and our DPF warning light page helps if yours comes on.
Recent recalls. CarsGuide reported 13,042 2024-2025 Prados recalled in June 2026 over software that may stop the engine oil pressure light showing, and 524 built June to October 2024 where an electric brake controller fitting may have disturbed the driver's airbag.

Prado servicing and battery
Toyota keeps the Prado on six months or 10,000 km, shorter than most makes. If a qualified independent mechanic follows that schedule and Toyota's specifications, it doesn't by itself void the new car warranty. CarsGuide's summary of the seven-year engine and driveline cover puts the weight on the intervals and logbook records, so keep them spotless, and read your own book's conditions.
The J250 that arrived in June 2024 pairs the 2.8-litre with a 48V mild-hybrid system, so it has more than one battery to think about. If you're chasing a Toyota Prado battery replacement, tell us which model. A touring Prado with a second battery or fridge setup also needs that mentioned. A local mechanic who specialises in your car.
Where we'd start with a Prado
Service book in hand, ask two things before any work: does this engine have a belt or a chain, and what's the last record of it? Have the mechanic show you on the car. On a used 3.0, we'd also pay for a good inspection before buying, given the piston history. And stick to the six-month schedule even if the kilometres are low.
