I have used Brian several times just in the past 2 months alone for my 2005 Ram 1500 SLT. Each repair is completed in the allotted time that was giving along with the pricing . I will being using Brian as my mechanic for as much repairs needed as possibly , and will continue to do so in the future. I feel Brian is knowledgeable , shows up at the appointment time, friendly, and has a great working attitude, and a good people person. I have trust in all of Brian's repairs. I actually have to get some work done on the wife's Jeep in a couple of weeks and look forward to Brian also making them repairs. Thanks Brian great job. I have already told lots of my fellow co workers about Your Mechanic.

Carlos R. was incredible, everything that I have come to expect of the YourMechanic technicians. I was cancelled on 3 times this week by another tech, forced to rent a car and take unexpected costly Uber trips, had to take off 4 hours of work to be there on time for the previous appointments (was cancelled on last minute anyways), damaged integrity/trust with a project team at work and had to push a big deadline back, had a horrible experience (ongoing unfortunately) with communication from a service manager after 6 attempts to just get a chance to talk to someone (not even a call, but I get an email at 11PM with info I already had the night before my 7AM appointment??), and to top it off all of that happening BEFORE SOMEONE EVEN LOOKED AT MY VEHICLE a week later. Needless to say, my service ended up costing me well over 100% of what I willingly paid today for the quality work.. not exactly what they advertise at YourMechanic (professional, convenient, fair priced, timly, hassle free, honest). Carlos R. made a huge impact on me today and likely the only reason I'd even consider coming back, and likely for now he's all I'd even consider going to. Professional, communicative, skilled, quick, and an all around great guy. I sincerely hope that YourMechanic can right some wrongs from this week, but they're doing one thing very right and that's having Carlos R. Thank you sir for giving me a little hope when I can't even get a chance to talk to someone on the phone. You're doing everything right!

Serpentine/Drive Belt Replacement Service

What is a serpentine belt and how does it work?

A serpentine belt is a relatively long, flat, multi-ribbed belt that is driven by the engine’s crankshaft pulley. The belt drives many, and often all, of the engine accessories such as the alternator, air conditioning compressor, power steering pump, water pump, and air pump. The serpentine belt is tensioned by a hydraulic or spring-loaded automatic tensioner. Some older cars use a serpentine belt to drive most accessories but will also have a shorter v-style belt to drive, for example, the power steering pump.

Belts

When to consider replacing the serpentine belt:

  • Regularly scheduled maintenance. Typically, belt manufacturers recommend belt replacement at 90,000 miles. However, the belt must be inspected for wear or damage at regular intervals prior to this high mileage.
  • Squealing noise, belt slippage, visible belt damage. Should the belt fail or wear out prematurely, you may hear noise or you may see visible signs of deterioration such as missing chunks of rubber, excessive cracking, or a shredded appearance on the edge of the belt.
  • Battery Light. A loose belt, perhaps caused by a defective tensioner, may not drive the alternator at adequate speed and thus the battery may discharge, causing the warning light to illuminate.
  • Engine overheating. Often, the serpentine belt drives the water pump. In those applications, if the belt breaks the engine will overheat in seconds to minutes. If the belt is inadequately tensioned, you may notice higher-than-normal engine operating temperature.

How do mechanics replace the serpentine belt?

  • Prior to removing the belt, the mechanic must run the engine to determine if the idler pulley and the belt tensioner are noise-free. Those rotating components have grease filled bearings and are subject to wear. In addition, the mechanic will ensure that all pulleys and accessories are turning in the same plane. These steps help make sure your new belt will operate trouble-free for its full-service life.
  • The belt’s routing path through the various components is noted. The belt tensioner is released, usually with a wrench or lever, to release the tension from the belt. With the tension off, the belt slides off the pulleys.
  • All rotating components — that is the alternator, air conditioner compressor, etc. — are checked for smooth operation and no noise.
  • If everything checks out, the new belt is slipped over all of the pulleys while holding the tensioner away from the belt. Once the belt is centered on all pulleys, the tensioner is released and the installation is complete. The engine is run to ensure normal operation.

Is it safe to drive with a serpentine belt problem?

No. Should the belt have visible damage, you risk unexpected and sudden breakage that could potentially leave you stranded. Serpentine belt problems that result in the alternator not charging may cause the battery to discharge, which will result in loss of electrical power to the vehicle. Additionally, if a deteriorated belt breaks and that belt drives the water pump, the engine will overheat in a matter of seconds.

When replacing the serpentine belt keep in mind:

  • On many cars, the expected service life of a serpentine belt is around 90,000 miles. Should the belt fail well prior to that, a very careful inspection should be performed to check for out-of-alignment pulleys, a possibly out-of-position crankshaft harmonic balancer on which the drive pulley is mounted, binding pulleys, or a defective belt tensioner.
  • Attention should always be given to serpentine belt routing, since proper routing is critical to proper belt tension, and function of the driven components.
  • Sometimes it is difficult to distinguish serpentine belt related noise from other engine noises. In these cases, a mechanic will determine the origin of the noise by momentarily running the engine without the serpentine belt attached.
