Automotive Tips from Davis Automotive Repair: Serpentine Belt System Wear

The primary job of the serpentine belt for Centennial drivers is to provide important traction to spin the accessories. As the belt wears it loses some of its grip and the accessories may not spin at optimal speeds. For example, if your alternator doesn’t spin fast enough, the battery will not completely recharge while you’re driving and you could end up stranded around Centennial with a dead battery. In short, a worn serpentine belt will stress all of the accessories it powers leading to premature wear and possible early replacement. When as little as 5% of belt material is lost, the serpentine belt cannot provide the proper traction for the accessories. Your friendly and professional Davis Automotive Repair service advisor can inspect your belt for excessive wear and replace your serpentine belt system if it’s excessively worn.Give us a call.Davis Automotive Repair6867 South Emporia StreetCentennial, Colorado 8011230

The Edible Engine

You may have had a friend whose vehicle was the victim of hungry rodents.  After all, mice, rats and squirrels—even rabbits—have been known to gnaw on wires in engine compartments, causing vehicle electrical systems to go haywire.  They can disable a vehicle completely and be very expensive to fix. In 2017, some drivers noticed their vehicle's wiring was being chewed and found out the automaker was using a relatively new material for covering their wires: soy.  Many of the repairs to their new vehicles weren't covered under warranty by the manufacturer when it was discovered rodents were eating the wiring.  So the owners filed a class action suit, saying the soy covering was essentially baiting the critters.  The automakers tell a different story, saying mice, rats and squirrels have been chewing through wire insulation long before it was made out of soy.  Regardless of what the insulation is made of, vehicle owners should make sure rodents are ... read more

The Davis Automotive Repair Guide to Vehicle Diagnosis

Modern Centennial vehicles have several computers on board that control all kinds of things like engine functions, transmission shifts, traction control, anti-lock brakes, stability control, emissions – and on some vehicles, even steering, braking and the throttle.Think about that for a minute – things that used to be controlled by simple mechanical connections now have electronic controls that rely on computers, software and sensors. It's no wonder that when something goes wrong with their vehicle it can be pretty complicated for Centennial drivers to track down the source of the problem.To help your service advisor at Davis Automotive Repair figure out what's wrong, your vehicle is equipped with on-board diagnostics. The Check Engine light comes on to tell you there's a problem and the engine management computer stores a trouble code.

Differential Service at Davis Automotive Repair

Here at AutoNetTV, we have national viewers, like your neighbors in Centennial, who write to us with questions or feedback. One common question we're asked is: "What is a differential and what does it do?" You may have been told by your Davis Automotive Repair service advisor that your differential needs serviced, or it's seen it as an option up on the service menu. Differential service at Davis Automotive Repair covers a lot of things, so let's first talk about what a differential does.As you drive through a turn, your outside wheels and inside wheels turn at different speeds. Kind of like the cars going around a race track - the ones driving in the outside lanes have a greater distance to travel than the cars in the inside lanes. The differential is what allows the outside and inside drive wheels to rotate at slightly different speeds so that the tires don't hop or skip while taking corners, or lose traction in dirt or snow o ... read more

Keep Your Cool in Centennial

Centennial drivers rely on their vehicle's coolant system to keep their engine cool. Coolant (also called antifreeze) mixed with water flows through your vehicle engine and absorbs heat. The mixture then flows out to the radiator where it's cooled by air flowing over the radiator. From there the coolant/water mix circulates back through the engine to absorb more heat.There's a reason we mix coolant and water. Water alone actually does a good job transferring heat from the engine. The problem is that water boils at a temperature that's easily reached inside your vehicle's engine, so it can turn to steam which does not conduct heat as well and is harder to contain.Also, if it's freezing outside in Centennial, the water in your engine could freeze while your vehicle is sitting out in the Colorado cold.So, if you remember your high school chemistry, you'll know that a mixture has both a higher boiling point and a lower freezing point ... read more
