Timing Belt Replacement: When to Do It And Why It’s So Important
If you’re like most drivers, the timing belt isn’t something you think about until it’s too late. But this one component plays a vital role in keeping your engine running smoothly, and replacing it at the right time could save you thousands in repairs.
At Bret’s Auto Repair in Lynnwood, we’ve seen what happens when timing belts are ignored and we’d rather help you prevent a major breakdown before it happens.
What Is a Timing Belt, and What Does It Do?
The timing belt is a toothed rubber belt that synchronizes your engine’s crankshaft and camshaft(s), ensuring your engine valves open and close at the right time. It keeps your engine running efficiently; and if it breaks, the engine could suffer catastrophic internal damage.
When Should You Replace a Timing Belt?
Most manufacturers recommend timing belt replacement between 60,000 and 100,000 miles, but this varies by make and model.
General Guidelines:
- Honda/Acura: 90,000 to 105,000 miles
- Toyota: Some models have chains; others require belt replacement around 90,000 miles
- Subaru: 105,000 miles (for belt-driven engines)
- Older models: May require more frequent inspection due to belt age, not just mileage
Check your owner’s manual, or call Bret’s for a service interval check.
Why Replacing It On Time Matters
A failed timing belt can cause complete engine failure, especially in interference engines (which most Japanese vehicles have). Valves can collide with pistons, leading to bent valves, cylinder head damage, or worse.
Cost comparison:
- Timing belt replacement: $600–$1,000
- Engine repair from timing belt failure: $2,500–$5,000+
Signs Your Timing Belt May Be Worn
While timing belts often fail without warning, you might notice:
- Engine misfiring or rough idling
- Ticking noise from the engine
- Oil leaking near the timing cover
- Loss of power
Don’t wait for symptoms; it’s a preventive maintenance item.
Pro Tip: Replace Related Parts Together
When replacing your timing belt, we also recommend:
- Water pump (often driven by the timing belt)
- Tensioner and pulleys
- Drive belts (if worn)
It saves on labor costs and reduces the chance of future failures.
