What year do 4Runners have timing chains?
Toyota 4Runners have used timing chains instead of timing belts in their engines since the mid-1990s. The specific year when 4Runners transitioned to timing chains varies by model year and engine type, but in general, 4Runners have had timing chains since the late 1990s and early 2000s.
Timing Chains vs. Timing Belts in 4Runners
Timing chains are metal chains that connect the crankshaft to the camshaft, while timing belts are made of reinforced rubber and perform the same function. Timing chains are generally more durable and longer-lasting than timing belts, with a typical lifespan of 150,000 to 200,000 miles or more. Timing belts, on the other hand, typically need to be replaced every 60,000 to 90,000 miles.
The switch to timing chains in 4Runners was driven by Toyota's desire to improve the reliability and longevity of their engines. Timing belt replacement can be an expensive and labor-intensive process, so the move to timing chains helped reduce maintenance costs for 4Runner owners over the long run.
When Did 4Runners Start Using Timing Chains?
The exact year when 4Runners started using timing chains varies by engine type and model year:
- 4Runners with the 3.4L V6 engine (1996-2002) used timing chains.
- 4Runners with the 4.0L V6 engine (2003-present) also use timing chains.
- Earlier 4Runners, such as the 2.4L and 3.0L models from the 1980s and early 1990s, used timing belts.
So in summary, the majority of 4Runners have had timing chains since the late 1990s and early 2000s, with the transition occurring as Toyota updated and improved the engines in this popular SUV model.
How many miles does a Toyota timing chain last?
When Should It be Replaced? Unless your engine has a specific replacement interval, the commonly accepted mileage is between 80,000 and 100,000 miles. However, the timing chain isn't necessarily a maintenance item and can last the engine's life, provided you change the oil regularly and maintain the rest of the engine.
