Where is the serpentine belt on an engine?
Where is the serpentine belt on an engine?
The serpentine belt on an engine is driven by a pulley on the front of the crankshaft, which protrudes out of the front of the engine. Surrounding the protruding end of the crank where it sticks out from the engine block is something called the crank seal, or more precisely the “front main seal.”
When do you need a serpentine belt tensioner?
While we have seen great improvements in belt construction and longevity with EPDM rubber materials, the design of the spring-loaded automatic belt tensioner has remained largely unchanged. Most serpentine belt requests occur after the customer notices the squealing or chirping noises.
Is it safe to drive without a serpentine belt?
You CAN drive without a serpentine belt but, you won’t get far and will risk damaging the engine. Cars are designed to start and keep running for some time even after the serpentine belt has snapped, but that doesn’t mean that it’s a good idea to drive without it.
How does the serpentine belt work on a BMW n5x?
This is a hard sealing ring that basically keeps the engine oil in and outside elements out. On N5X engines, the crankshaft pulley that drives the serpentine belt sits a little closer to the engine block than on other engines, creating a slightly narrower gap between the pulley and the engine.

What are the symptoms of a bad serpentine drive belt?
Symptoms of a Bad or Failing Serpentine/Drive Belt. Common signs include a squealing noise from the front of the vehicle, power steering and AC not working, engine overheating, and cracks on the belt.
How often does a serpentine belt need to be replaced?
Without a properly functioning serpentine belt, the engine may not run at all. As a general rule, a serpentine belt lasts up to 50,000 miles or five years before it need to be replaced.
What causes a serpentine belt to snap off?
In some more rare cases, belt misalignment can cause the problems. Whatever the case may be, make a replacement as soon as possible so the belt doesn’t snap.
What happens when a belt gets sucked into the engine?
When that happens, it is a very big problem. The belt gets chewed up and shredded in the process and bits of belt material get strewn all over the place. It can clog up the screens in the oil pick-up tube and generally wreak havoc throughout the engine and must be thoroughly, painstakingly cleaned out.
