A big part of the service we provide at Davis Automotive Repair for our Centennial customers is education. We want you to feel confident with your service decisions. And we're always open to questions from our valued Centennial area customers. Even though we try to be proactive in our Davis Automotive Repair automotive education, we sometimes get busy fixing vehicles and need a reminder. Please, just ask.

They've grown to trust that our recommendations are based on the vehicle manufactures’ published maintenance schedules and that Davis Automotive Repair is not just pulling them out of the air. We know that people in Centennial live a busy life with a lot more to think about than wondering if it's time to replace the PCV valve on their vehicle.

A lot of us Centennial drivers like our vehicles to reflect our personalities. We're picky about color and body style. We'll customize anything from floor mats to window tints to license plates. One popular way for Colorado motorists to customize a vehicle is to get new wheels.Wheels come in thousands of designs. Custom wheels can add personality, style or sass to a vehicle. Many of these customizations involve getting a bigger wheel.Fifteen or 16-inch wheels used to be the factory standard, but today, because a lot of Centennial drivers like the look of larger wheels, many vehicles are available with 17 or 18-inch wheels. Optional wheel packages of 20 inches or more are also available in Centennial.If you want to upsize the wheels on your current vehicle, however, you should know it's not a do-it-yourself project. There are factors involved in ensuring your wheel change doesn't jeopardize the safety of your vehicle.First of all, you need to understand rolling diameter ... read more

Oil changes are probably the most recognized service on a vehicle. Almost all Centennial residents know about them. But do we know enough?Several decades ago, oil changes were fairly standard: every three months or 3,000 miles or 5,000 kilometers. But recent advances in both engine technology and oil quality have led to longer oil change intervals.Delayed or skipped oil changes are a problem for Centennial residents because they lead to the build-up of oil sludge in your engine. Oil sludge forms when engine oil breaks down, which happens with both time and miles. Obviously, driving will take its toll on engine oil, but the oil also breaks down even as the vehicle just sits in the garage. This is why oil change intervals are listed in both time and distance traveled, and the phrase “whichever comes first” is applicable.Oil sludge is essentially petroleum jelly. Imagine this stuff squishing around in your vehicle engine, pushing into small engine passageways and blocking ... read more

Starting in 1996, Davis Automotive Repair service technicians have been able to use a standardized diagnostic system to help determine what is wrong with a vehicle. This diagnostic system works in tandem with the Engine Control Modules for each vehicle's engine. The Engine Control Module is a computer that monitors and controls many engine functions.Sensors throughout a vehicle send readings to the Engine Control Module. These readings help the computer make adjustments in various vehicle systems to allow for constantly changing driving conditions and even to compensate for minor problems. However, if the computer encounters a situation it can't adjust for, it turns on the Check Engine light. (The Check Engine light is called the “service engine soon” light on some vehicles.)If the Check Engine light is burning steadily, it indicates a problem that needs to be taken care of soon. If it is flashing, however, the vehicle need ... read more

Knowing how their engine works can help Centennial drivers make informed decisions about auto care and prevent repairs to their vehicles. This is especially true when it comes to timing belts.An engine's power is generated in the cylinders. Inside the cylinder is a piston that moves up and down while the engine is running. Power is generated in a cycle that includes four strokes of the piston. First, the piston drops and a valve at the top of the cylinder opens to let in fuel and air. The piston then rises, which compresses the fuel and air. At this point, the spark plug fires, igniting the fuel and pushing the piston down. This downstroke transfers energy to the engine, which provides the power it needs to run. The piston rises again, and a valve opens to release the exhaust.All of this movement is orchestrated by a timing belt. The timing belt is so named because it keeps the pistons and valves operating in synch with each other, just as a conductor keeps all of ... read more
