My car was running rough and shaking when idle, so I booked an appointment for an inspection. My mechanic was Jose Guzman. He did an inspection, and he found the car has eccentric shaft sensor and camshaft Position Sensor problems in just less than 10 minutes. I was impressed by his knowledge and experience about cars. He did a great job today.

All about Serpentine/Drive Belt Replacement

The serpentine/drive belt or v-belt is a rubber belt that connects the alternator, power steering, and AC to the part of the engine (crankshaft) which transfers the power from the engine to those components. Without this belt, the battery will not get charged and none of the electrical accessory components in the car will work. The serpentine belt and v-belt are also known as "drive belts." Because of the high amount of heat in the engine, the belt can develop cracks over time and eventually break. If the belt breaks, the steering wheel will be difficult to turn and driving will be hazardous. In some cars, water pumps are driven by the drive belts. If the belt breaks, water and coolant needed to keep the engine cool will not properly flow to the engine. The engine will overheat, potentially causing severe damage.
