When should I replace my timing chain on my Toyota Highlander?
The timing chain on a Toyota Highlander is a critical component that ensures the proper synchronization of the engine's valves and crankshaft. While timing chains are designed to last the lifetime of the vehicle, there are certain circumstances when you may need to replace the timing chain on your Highlander.
Signs It's Time to Replace the Timing Chain
- Mileage Recommendation: Toyota generally recommends replacing the timing chain on a Highlander around the 90,000-120,000 mile mark, or approximately 7-10 years of use.
- Engine Noise: If you hear a rattling or ticking noise coming from the engine, it could be a sign that the timing chain is wearing out and needs replacement.
- Engine Misfiring: Misfiring or rough idling can indicate that the timing chain is slipping, causing the engine's timing to be off.
- Check Engine Light: If the check engine light illuminates on your Highlander's dashboard, it may be due to an issue with the timing chain.
It's important to address any issues with the timing chain promptly, as a failure can lead to significant engine damage and costly repairs.
