This can lead to a rough idle, as the engine struggles to maintain a consistent speed.
Additionally, a loose or damaged belt can cause vibrations that can be felt throughout the vehicle. It is important to have the belt tensioner and belts inspected regularly and replaced if necessary to prevent further damage to the engine and ensure smooth operation.
How much does it cost to fix a belt tensioner?
Replacing a belt tensioner can be quite expensive, with costs ranging from $140 to $400. The final price will depend on the specific parts required, such as idler pulleys and bearings, as well as the cost of labor. Typically, labor costs around $70 to $80 for an hour-long replacement.
Can a car run without a belt tensioner?
On the topic of how long a car can run with a broken serpentine belt, there are a few variables to consider. Generally speaking, the car can continue to run for anywhere between 20 to 90 minutes. However, it’s important to note that the engine will overheat much faster without a properly functioning cooling system, especially on a hot day. This means that your driving time may be limited.
Is a serpentine belt the same as a tensioner belt?
The serpentine belt is an important component of a vehicle’s engine system, and the tensioner plays a crucial role in keeping it tight. Positioned on the outside of the smooth side of the belt, the tensioner applies pressure to ensure that the belt remains taut. Over time, the belt may stretch, and the tensioner compensates for this by increasing the tension. If the tensioner is broken, it may produce clicking or squealing sounds, indicating that it needs to be replaced.
How long does a belt tensioner last?
