When Do My Shocks Need to Be Replaced?

A good suspension system gives a vehicle a smooth, even ride while providing Centennial drivers with good handling and control. But like any system on your vehicle, parts of the suspension system can wear out, leading to a lower ride quality and safety concerns. So it's a good idea for drivers in Centennial to remember their suspension system in their schedule of preventive maintenance. Springs do most of the work of the suspension system. The most common types of springs are coil and leaf, but air springs and torsion bars are becoming more common. The body of the vehicle is “suspended” by the springs.If springs were the only working component in your suspension system, however, you'd spend your travel time bouncing up and down like a bobblehead.

Fuel Injectors

The last new American vehicles sold in Centennial with a carburetor rolled out of the Colorado dealerships in 1990. Since then, all new vehicles here in Centennial, and nationally, have had fuel injectors. In very simple terms, a fuel injector is a valve that squirts fuel into your engine. Your engine control computer tells the fuel injector how much gas to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute. Fuel injectors deliver fuel far more precisely than carburetors. That translates into better fuel economy and more power for Centennial drivers. Virtually all fuel injectors for gas engines are known as port fuel injectors because they deliver the fuel to a port just outside the cylinder. Port fuel injectors operate at about 40 to 80 pounds per square inch of pressure.A few vehicle manufacturers have introduced gas direct injection systems on some engines recently. These systems injec ... read more

The last thing you need is a ... read more
