Timing Belt Replacement
What is a timing belt?
The timing belt connects the engine's camshaft and crankshaft, and ensures that they maintain proper timing to keep the engine running smoothly.
When you have it replaced, it might be smart to have related work done to help save on labor. Parts such as pulleys, serpentine belts, tensioners and the water pump are usually worth replacing if they show wear or signs of failure. These repairs are not included in the estimate above.
How does the timing belt work?
The teeth on the belt mesh with the crankshaft timing gear and camshaft timing gear. The belt is held tight by a tensioner to ensure the belt doesn't skip a tooth, or “jump time.” The timing belt may turn an additional gear for the water pump.
A worn timing belt can result in trouble codes from the camshaft or crankshaft sensors, causing a dashboard warning light to be lit.
The engine can make slapping or scraping noises if the timing belt is loose or worn. Adjustment may take care of the noise, but replacement may also be necessary.
What are the symptoms related to a bad timing belt?
Most timing belts will need to be replaced as part of regular maintenance every 60,000 to 100,000 miles, and most related problems are caused by not replacing it when you’re supposed to.
If the timing belt is starting to go bad, the engine will run poorly and the check engine light will likely come on. If the belt breaks, the engine will stall immediately, and internal engine damage can occur.
