December Repair of the Month

Shawn Gilfillan • December 20, 2022

2017 Ford Fusion with multiple different electronic issues, from lights and dashboard not working, radio acting weird, and many little random glitches that don't add up. Our technician was able to diagnose the issue and deemed it to be CAN bus-related. These issues are normally very difficult to diagnose or even impossible for some without proper training and experience.

These days, all modern vehicles, from conventional combustion-powered cars to the latest EVs, feature a Controller Area Network (CAN) bus. It's the electronic communication system that lets everything be able to talk to each other including the engine, transmission, body control, and even brakes. It works the same way a computer communicates with its own parts, with 0's and 1's. Literally, multiple pulses or pauses of electricity (0110101001) just like Morse code.

Computers are able to understand this language and can respond properly. This is much different and far more advanced than the older cars without this system.

Our Technician concluded there were multiple chewed wires and a shorted-out CAN module thanks to his dedication to advanced electrical diagnostic skills. He knew if we disassembled the interior of this car we would find multiple issues with the vehicle's main wiring harness running in all directions from the front to back roof to floor and everything in between. After disassembly, his hypothesis was correct finding many chewed-through wires and evidence of rodents.

After fully replacing the Fusion's entire wiring harness and CAN control module and reassembling the entire interior, we have completely restored this vehicle to its fully operational state.

Drive Belts & Pulleys: The Unsung Heroes Under Your Hood

April 9, 2025

When it comes to car maintenance, there is a lot that comes into play. It can almost be overwhelming at times. Focus on common wear items like the battery, brakes, and tires are usually at the top of the list for most, but there are other items that need attention as well. Drive belts and pulleys are some of these items. These small components help keep your car running smoothly, and after a while they do wear out and need replacement. Unfortunately, failure can lead to a breakdown on the side of the road and leave you needing a tow. So what are they and what do they do? Let’s find out. What Are Drive Belts and Pulleys? Think of drive belts as super strong rubber bands that transfer power from your car’s engine to help run other important components. The pulleys are similar to any other pulley; they are just metal wheels that help guide and control the belts movement. However, these pulleys are attached to other engine accessories, and when the belt spins the pulleys they provide power to these other accessories. Together, they keep essential parts of your car operating. Most modern cars use a serpentine belt, a long, continuous belt that is wrapped around multiple pulleys that power multiple systems. Older vehicles might have V-belts, which are shorter and typically run a single component at a time. What Do Drive Belts and Pulleys Power? Drive belts are made from durable rubber and reinforced materials, but they don’t last forever. Over time, they can crack, stretch, fray, glaze, or even snap. Pulleys have a lifespan as well. They are subject to corrosion and the bearings can go bad and even seize up completely. Without drive belts and pulleys, several key systems in your car wouldn’t function properly. Here’s what they keep running and what can happen if they fail. Alternator – Powers your car’s electrical system and keeps the battery charged. If the belt breaks, your battery will eventually die, leaving you with a car that won’t start or may die while you are driving. Water Pump – Circulates coolant to prevent your engine from overheating. A broken belt could lead to severe engine damage due to overheating. Power Steering Pump – Makes turning the steering wheel easier. If the belt slips or breaks, steering your car instantly becomes much harder, especially at low speeds. Air Conditioning Compressor – Helps keep your car cool on hot days. While not as critical as other components, losing A/C can be uncomfortable. Drive Belts and Pulley Maintenance Drive belts and pulleys don’t necessarily require maintenance, but they should be inspected regularly. In some cases, a bad pulley can cause the belt to slip or even pop off of the pulley completely. There are a few things to look for that may tell you it’s time for replacement. Check for Cracks, Fraying, or Glazing – Look for visible signs of wear on the belt. If you see cracks, missing ribs, fraying, or a shiny, glazed appearance, it’s time for a replacement. Listen for Strange Noises – A worn out belt or pulley may slip on the pulleys and cause a high-pitched squealing, chirping, or rattling noise when you start the car or turn the wheel. Watch for Performance Issues – If your battery warning light comes on, your power steering feels heavy, or your car starts overheating, a belt or pulley could be the culprit. Have Regular Inspections – Most belts last between 50,000 to 100,000 miles, but checking them during routine maintenance can prevent unexpected failures. Replace Before It Fails – A worn belt may still work, but it could snap at any moment. Replacing it early saves you from the headache of a sudden breakdown. Final Thoughts Drive belts and pulleys may not be the most glamorous parts of your car, but they play an essential role in keeping your car running smoothly. Keeping them in good condition helps ensure your car stays reliable and safe. At Automotive Magic , we offer a bumper to bumper vehicle health inspection that includes checking belts and pulleys for wear. Our inspections are sent to you with photos, videos, and descriptions explaining any issues we find with your vehicle and their severity to keep you on the road with confidence.
