How often should timing belts be replaced on Prado?
The Toyota Prado lineup predominantly uses timing chains instead of timing belts in its modern engines, so there is no regular belt-change interval for most models. If your Prado does have a timing belt in a rare or older engine variant, the replacement window is typically around 100,000 km (about 60,000 miles) or 5–7 years, whichever comes first. Always verify with your owner's manual or a Toyota dealer for your exact engine and market.
In practice, some Prado engines rely on timing chains rather than belts, which do not require a standard replacement interval. The key is to know your specific engine code and model year, since maintenance schedules are engine-family and market dependent. This article outlines what you need to know, how to determine what your Prado has, and what maintenance to watch for.
What to know about belts vs. chains in Prado engines
The critical distinction is whether your Prado’s engine uses a belt-driven or chain-driven timing system. Modern Prados largely use timing chains, which are designed for long service life with appropriate oil maintenance and occasional inspection. A timing belt, when present, requires a planned replacement to avoid the risk of sudden engine damage.
For belt-driven configurations, the typical replacement window and service should be confirmed in the official schedule for your exact engine code and year. The following points summarize the general expectations where belts are involved:
- Belts in Prado engines, if present, are usually replaced around 100,000 km (60,000 miles) or 5–7 years, whichever comes first.
- When replacing a belt, it's common to replace the tensioners and idlers at the same time to prevent future wear from compromising the new belt.
- In severe operating conditions—dusty or off-road use, frequent towing, extreme temperatures—the replacement interval may be sooner than the standard window.
Bottom line: belt-related maintenance is engine-specific; most Prado owners will not encounter a routine belt replacement, thanks to widespread use of timing chains in current generations.
How to determine whether your Prado has a belt or a chain
To confirm the timing system on your specific Prado, use these steps:
- Check the engine code and reference the official service schedule for your exact model year and market.
- Look in the owner's manual or service booklet for notes on timing belt versus chain and the recommended replacement interval.
- Ask a Toyota dealer or a qualified mechanic to verify via the vehicle identification number (VIN) or by inspecting the timing cover layout.
Conclusion: Most modern Prados use timing chains; belts are uncommon. Always verify with authoritative sources for your exact engine code and year.
Signs of timing-system wear to watch for
Even with chains, timing components can wear over time. Look out for these indicators and address them promptly:
- Rattling or slapping sounds from the engine during startup or idle, which can indicate worn tensioners or guides.
- Engine performance issues such as misfires, rough running, or poor acceleration.
- Oil leaks around the timing cover or tensioners, which can affect chain/tensioner operation.
- If your engine uses a belt (rare for Prado), unusual belt wear, cracking, or fraying would be warning signs necessitating immediate service.
If you notice any of these symptoms, stop driving and seek inspection from a trained technician to prevent potential engine damage.
Summary
For the majority of Toyota Prado models, timing belts are not part of routine maintenance because engines use timing chains. If you own an older or region-specific Prado with a timing belt, the typical replacement window is around 100,000 km or 5–7 years, but always check your exact engine code and market guidelines. Rely on the owner's manual and your local Toyota dealer for the precise schedule, and have timing systems inspected regularly as part of standard maintenance. Regular oil changes and engine care help preserve timing chains where they are used.
How long do timing belts last in Toyota's?
In most cases, the average timing belt will last anywhere between 60k-90k miles. If your vehicle has over 90,000 miles and has not had the timing belt replaced, you may want to schedule an inspection to ensure safe operation of your vehicle.
How much does it cost to replace a timing belt on a Toyota Prado 150?
The typical cost for replacing a timing belt begins at approximately $550 and may rise to more than $1300 if additional engine components need to be removed for access to the timing belt.
When should the timing belt be changed on a Toyota Prado?
A timing belt can last anywhere between 40-100k km's.
Does the Prado have a timing belt or chain?
The 2020 model of the Toyota Landcruiser Prado, however, does not use a timing belt, but rather is equipped with a timing chain. This is an important distinction since timing chains generally require less maintenance compared to timing belts.
