What year do 4Runners have timing chains?
The Toyota 4Runner is a popular SUV known for its durability and off-road capabilities. One of the most common questions among 4Runner owners and potential buyers is whether their vehicle uses a timing chain or a timing belt. This distinction is important because timing chains generally require less maintenance than timing belts. In this article, we’ll explore which years of the Toyota 4Runner are equipped with timing chains and provide some helpful maintenance tips.
Timing Chains vs. Timing Belts: A Quick Overview
Before diving into the specifics of the Toyota 4Runner, it’s important to understand the difference between timing chains and timing belts:
- Timing Chains: Made of metal, timing chains are durable and designed to last the lifetime of the engine with proper maintenance. They are lubricated by engine oil and typically require less frequent replacement.
- Timing Belts: Made of rubber, timing belts need to be replaced at regular intervals (usually every 60,000 to 100,000 miles) to prevent engine damage.
Understanding which component your vehicle uses can help you plan for maintenance and avoid costly repairs.
Which Toyota 4Runners Have Timing Chains?
The type of timing mechanism in a Toyota 4Runner depends on the engine type and model year. Here’s a breakdown:
- 1990-2002 Toyota 4Runners: These models primarily used timing belts, especially in the V6 engines (e.g., the 3.0L V6 and 3.4L V6).
- 2003-Present Toyota 4Runners: Starting with the fourth generation (2003-2009), most Toyota 4Runners transitioned to timing chains. The 4.0L V6 engine introduced in 2003 uses a timing chain, while the optional 4.7L V8 engine in these years still uses a timing belt.
- 2010-Present Toyota 4Runners: The fifth-generation 4Runners (2010 and newer) exclusively use timing chains in their standard 4.0L V6 engines.
In summary, if you own a Toyota 4Runner from 2003 or later with a V6 engine, it likely has a timing chain. However, if your 4Runner is equipped with the older V8 engine, it may still use a timing belt.
Why Timing Chains Are a Preferred Choice
Many modern vehicles, including the Toyota 4Runner, have shifted to timing chains for several reasons:
- Longevity: Timing chains are designed to last the life of the engine, reducing the need for costly replacements.
- Durability: Made of metal, timing chains are less prone to wear and tear compared to rubber timing belts.
- Maintenance: With proper oil changes and engine care, timing chains require minimal maintenance.
These advantages make timing chains a reliable and cost-effective choice for many drivers.
Maintenance Tips for Timing Chains
Although timing chains are low-maintenance, they still require some care to ensure optimal performance:
- Regularly change your engine oil to keep the timing chain properly lubricated.
- Listen for unusual noises, such as rattling, which could indicate a loose or worn timing chain.
- Follow your vehicle’s maintenance schedule and address any engine issues promptly.
By following these tips, you can extend the life of your timing chain and avoid unexpected repairs.
Conclusion
In summary, Toyota 4Runners from 2003 onward with V6 engines are equipped with timing chains, while older models and those with V8 engines may still use timing belts. Understanding your vehicle’s timing mechanism can help you plan for maintenance and ensure your 4Runner continues to perform reliably for years to come. If you’re unsure about your specific model, consult your owner’s manual or reach out to a trusted auto repair professional like Kevin’s Autos for assistance.

Does a 2013 4Runner have a timing chain or belt?
Newer models use timing belts made of polyurethane and Kevlar for long life and durability.
What year do Toyotas have timing chains?
Since 2001, they have instead been outfitted with timing chains. Whether your Toyota has a timing belt or a timing chain may also depend on which engine your vehicle has. From 1995 until now, the Toyota Tacoma with a 4-cylinder engine has come with a timing chain.
