When Centennial drivers think about preventive maintenance, what usually comes to mind is oil, fluids and brakes. We don't generally think about our shocks or struts, but these auto parts keep our tires on the road.Centennial drivers don't think about shocks as often as oil changes because shocks and struts last a long time and wear out slowly. They don't need to be checked as often as our brake pads or air filters. By the time your shocks have 50,000 miles (80,000 kilometers) on them, their performance will have noticeable degraded. If you want to restore the handling and ride designed for your vehicle, try replacing your shocks and struts.Of course, if you drive off-road around Centennial, carry heavy loads, tow a trailer or put in a lot of mileage on poor driving surfaces, your shocks or struts will wear out more quickly. You'll need to replace them more often or upgrade to better shocks.Your suspension system uses springs and shocks to absorb the “shocks&rdquo ... read more

Many Centennial car owners have probably wondered: "What's the harm in putting off replacing an engine air filter? The answer is that not replacing it could cause your Mass Air Flow (MAF) sensor to fail. This expensive sensor is situated between your engine air filter and your engine. Dirty air filters are a leading cause of mass air flow sensor failure – and these babies can cost several hundred dollars to replace in Centennial.Change your vehicle air filter at Davis Automotive Repair when it's dirty.

Centennial residents know that engines need to burn fuel to operate. Fuel is pumped from your fuel tank to your vehicle engine where it is squirted—or injected—into your engine's cylinders. This is the function of the fuel injectors.There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air—before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the vehicle engine.Direct injection engines burn fuel more efficiently than conventional vehicle engines. Some models can deliver the power of a V8 with the economy of a V6.For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same gas mileage. The turbocharged version delivers 350 horsepower ... read more

Hello Centennial, let's talk about brakes. But the mechanical aspects of the brakes themselves are just one issue. There's also the power brake pump and brake fluid. And then there are the tires, which are critical to the effectiveness of the brakes.Let's step back. A new vehicle or truck rolls off a local Centennial showroom floor. It has brand new brakes with brand new brake pads. The brake lines and pump are filled with fresh fluid and are completely clean inside. And the tires are brand new, with full tread. It is ready to go.Naturally, braking power is at its peak performance. Now the miles/kilometers start to add up on the vehicle. Centennial drivers tend to focus on the brake pads. In the automotive business, the pads and shoes on drum brakes are called the friction material. That's because they provide the friction used to stop the vehicle. The pads are designed to be effective throughout their useful life – it's not until they are worn so thin as to be ... read more
