Service Intervals 2

Question: I'm really confused about auto service intervals for various items on my car. Help! D AND E AUTO REPAIR Answer: The simple answer for CHICO residents is to follow the vehicle's recommended service intervals listed in your owner's manual or in your service center's database. But the team at D AND E AUTO REPAIR in CHICO sympathizes with CHICO residents because of the confusing intervals for modern vehicles. The days of simple rules of thumb that applied to most vehicles are long gone. For example, let's look at an oil change: manufacturers' recommendations run anywhere from every 3,000 miles (5,000 kilometers) to 15,000 miles (24,000 kilometers). This big range comes from engine design and recommended types of oil - so CHICO residents really do need to read and follow the recommendations for their specific vehicle. Your owner's ... read more

Steering

Steering is one of the things we take for granted in our vehicles.  Let’s break it down into two areas: first, the power assist and second the actual parts that steer the vehicle. Most people under 40 have never driven a car or truck without power steering.  Most vehicles today have a hydraulic power steering pump that provides boost to help you steer.  The pump is usually driven by the serpentine belt, but some newer vehicles have an electric pump.  Some vehicles even have an electric motor that directly powers the steering. The important thing to keep in mind is that these pumps and motors will eventually wear out and the hoses will start to leak.  You can postpone that day by having a power steering service from time to time.  We will drain the old fluid and replace it with fresh fluid.  This removes water and contaminants that can corrode power steering parts.  Ask your service advisor for the recommended change interval. What about ... read more

The 20.9 Percent Factor (Oxygen Sensor)

Do you know what gas makes up 20.9% of the air we breathe? It's oxygen.   Oxygen is an important part of the combustion process that enables your engine to make power.  The amount of oxygen in the exhaust provides clues as to how well your engine is running.  Your vehicle has oxygen sensors that provide the engine computer with the information it needs to adjust the combustion process. Many vehicles have more than one oxygen sensor.  They are positioned in the exhaust system, one between the engine and the catalytic converter, and another after the catalytic converter.  An onboard computer compares the oxygen levels before and after the catalytic converter to determine if the converter is working properly. An oxygen sensor may fail for many reasons.  You could have bad fuel that contaminated it.  Your sensor may have simply worn out.  Your engine may be burning oil, and that soot can ruin the sensor.  Road contaminants, like salt ... read more
