How long does a serpentine belt last on a car?
How Long Does a Serpentine Belt Last? Thanks to improvements in rubber technology, serpentine belts last much longer than they did back in the day. Most serpentine belts generally last between 50,000 and 100,000 miles. Eventually, your car’s serpentine belt will wear down from continuous exposure to heat and friction and will need to be replaced.
Why are stretch belts better than serpentine belts?
Stretch belts can take loads off of the main accessory belt drive, allow for better packaging and solve NVH problems that can occur with a longer serpentine belt. Less belt means less tension with fewer noise and vibration problems.
How much do serpentine belts stretch in a Jetta?
Serpentine belts don’t stretch much. This car is an ’83 Jetta so it has V-belts and those can loosen up a bit after some use. My memory is very hazy on this but some VWs of this era used rubber mounted alternators and/or rubber mounted A/C compressor/alternator brackets.
Why is my serpentine belt not working properly?
You can drive the car for some time without noticing any problems. Eventually, because of battery discharge, the lights will get dimmer and the car will start to crank poorly. Only then will you notice that you have a problem. Main cause of this problem is material fatigue of the belt so changing it on time will probably prevent this.
What is the average life span of a serpentine belt?
The lifespan of the serpentine belt will depend mostly on the type of material it’s made of. Older style belts generally last about 50,000 miles, while those made from EPDM can last up to 100,000 miles.
How do you install a stretch fit belt?
