TIMING BELT REPLACEMENT

Timing Belt Replacement

If your timing belt breaks or cracks, it can cause severe damage to your vehicle.  Because your timing belt is so critical to a positive driving experience, it is essential to have it checked as soon as a problem with your vehicle arises. Although the recommended interval for replacing your timing belt is every 100,000 miles, if you are experiencing any issues, it’s a good idea to bring your car to us so we can quickly diagnose and repair the problem.

How do I know if I need a timing belt replacement? Some signs of a bad or worn out timing belt chain include:
  • Your vehicle’s engine is stalling.
  • There are teeth on timing belts that grip gears as they rotate various engine parts and components. If these teeth start to fall off or become brittle, the timing belt can slip away from the gears.
  • There is smoke coming from your engine.
  • The top of every cylinder has two holes that let out engine exhaust and let in air. The opening and closing of these holes are synchronized with the movement of the cylinder and rotation of the camshaft. A worn or broken timing belt disrupts this synchronization, causing a buildup of exhaust that is released as smoke. This is a serious issue, and if you are in Boulder, CO, or the surrounding area, visit Pellman’s Automotive Service to have it checked out.
  • You hear odd noises coming from the engine.
  • If you hear a ticking noise from your engine, it could indicate a failing timing belt or low oil pressure.


Although the recommended interval to replace your timing belt is every 100,000 miles, if you are experiencing one or more of the symptoms above, it’s a good idea to bring your car to an auto repair shop that can quickly diagnose and repair the issue. That shop is Pellman’s Automotive Service in Boulder, CO. Our technicians and owners have decades of combined experience and advanced factory training in auto repair and timing belt replacement.

Frequently Asked Questions

  • How do I know when to replace my timing belt near me in Boulder?

    Consult your vehicle manufacturer's maintenance schedule(typically between 60,000 to 105,000 miles) or visit Pellman's Automotive for a timing belt inspection.
  • What happens if my timing belt snaps while driving?

    On interference engines, a broken timing belt causes the pistons to strike open valves, causing catastrophic cylinder head and valve damage that requires thousands in repairs.
  • What is the difference between a timing belt and a timing chain?

    A timing belt is made of reinforced rubber located outside the engine that requires periodic replacement. A timing chain is made of metal, runs inside the engine lubricated by oil, and usually lasts much longer unless oil changes are neglected.
  • Should the water pump be replaced at the same time as the timing belt?

    Yes. In most cars, the timing belt drives the water pump. Replacing the water pump, tensioner, and pulleys during timing belt service saves you duplicate labor costs later.
  • What are the warning signs that my timing belt or chain is failing?

    Timing belts rarely show outward signs before snapping, though ticking noises from the engine or engine misfires can occur. Timing chains often rattle upon startup due to worn tensioners.
  • How long does a timing belt replacement take at Pellman's Automotive?

    Replacing a timing belt and water pump is an involved procedure taking 3 to 6 hours depending on the engine layout. We offer loaner bikes and shuttle options for your convenience.
  • Why is timing belt replacement expensive?

    High costs are driven by the extensive labor required to strip down front engine covers and align crankshaft and camshaft timing marks perfectly during installation.
  • Can I visually inspect my timing belt myself?

    Some engines have removable access covers, but subtle cracking, internal cord wear, or missing teeth are often hidden from view. Having a professional technician check it is safest.
  • Does Pellman's Automotive service timing chain tensioners and guides?

    Yes, we replace stretched timing chains, worn plastic guides, hydraulic tensioners, and variable valve timing (VVT) actuators.
  • Does timing belt replacement come backed by a warranty?

    Yes, timing belt and water pump replacements at Pellman's Automotive are backed by our 3-year/36,000-mile nationwide warranty.
