Davis Automotive Repair Helps You Decipher the Menu Board: Part 2

Colorado service centers have a menu board that lists the services they provide. Some Centennial drivers may not be familiar with all of the items on the board so here is a quick description of some of the typical services that might be listed.Davis Automotive Repair fuel system cleaning: Over time, the vehicle fuel system gets gum and varnish built up. A fuel system cleaning gets rid of that and cleans out the fuel injectors. Saves gas, by the way.Davis Automotive Repair headlamp replacement: Halogen and standard headlamps gradually fade. It's usually good to change them every year or so.Davis Automotive Repair inspections: Centennial drivers get inspections for many reasons. Maybe they're going on a trip or just want to make sure their vehicle's ready for a Colorado summer or winter. Maybe they just bought a used vehicle and want to give it the once over. An inspection may reveal some things that are b ... read more

Clean Air for Your Engine: A New Engine Air Filter at Davis Automotive Repair

All of us in Centennial know we have to get the oil changed in our vehicles periodically. That's just part of good vehicle care. But when Davis Automotive Repair technicians change your oil, they also usually inspect your air filter. That's why they sometimes let you know that your air filter needs to be changed before releasing your vehicle.Don't just chock this up to trying to sell you something else. Centennial area drivers really do need to change their air filter when it gets dirty. You can check your owner's manual to see how often your air filter should need to be changed, but remember, if you live in an area in Colorado with poor air quality, or if you drive a lot or drive under harsh conditions in the Centennial area, you may need to change that filter more often than is recommended.Changing an air filter isn't guesswork. If a filter's dirty, it needs to be replaced. Air filters aren't very e ... read more

Professional Fuel System Cleaning

Getting adequate fuel to your engine is very important for performance, fuel economy and safety. In order to accomplish this, your fuel system needs to be clean.Today's production cars have fuel injectors, rather than a carburetor. The injectors need to be cleaned from time to time in order to deliver the fuel with the correct pressure, spray pattern and volume.Centennial drivers can buy fuel system cleaners that you pour into your gas tank to help maintain an already clean fuel system; however, they can't do a major cleaning. For that, you need to see Davis Automotive Repair in Centennial. We have the tools and chemicals to do the job right. Our friendly and knowledgeable team at Davis Automotive Repair can remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently. You'll find Davis Automotive Repair at 6867 South Emporia Street in Centennial, Colorado 80112. Or just give us a call at 303-790-4789 to schedule an appointment. You'll ... read more

Improve Fuel Economy with Proper Maintenance at Davis Automotive Repair in Centennial

With Centennial gas prices being what they are, many of us in Colorado are driving less and looking into purchasing smaller or more efficient vehicles. Centennial area residents who have to drive a lot, have large families or need four-wheel drive are particularly hard hit by the cost of fuel in Colorado. But there are things all Centennial drivers can do to save fuel: We can improve our driving habits and stay on top of preventive maintenance at Davis Automotive Repair. These things make small savings possible, but they can really add up.Let's start with driving habits. One major gas-eater is jackrabbit starts. A smooth, gradual acceleration uses a lot less fuel. It's also easier on your engine and drivetrain, so you'll prolong their lives as well.If you drive with one foot on the brake, stop. That creates drag, increasing fuel usage and reducing the useful life of your brakes.Slowing down can really add up on gas savings over time for Centennial driv ... read more

Colorado: What Is the Risk of High Oil Change Intervals?

Colorado residents may have heard that vehicles don't need their oil changed as often as they used to. That's true. But it's not the whole story.Owing to improved engine technology and higher oil quality, most newer vehicles can go longer between oil changes than their older counterparts.So what is a good time interval for oil changes? How do Colorado residents know when to change it? And why do we change it in the first place?Oil lubricates a vehicle's engine, which protects it from friction damage. Over time the oil can collect dirt and contaminants that inhibit its performance. But dirty oil isn't the only problem for Colorado residents. What you really want to avoid is called oil sludge.Oil sludge is caused by moisture in the oil and by hot spots in your engine that burn off oil. This sludge is a gooey gel that can clog engine passageways, which can block lubricants from reaching vital engine parts. The result can be engine wear or even engine failure.Sludge forms rapidly in an eng ... read more

Coolant/Antifreeze Service at Davis Automotive Repair

Anyone who drives a car in Centennial knows that engines get hot when they run. But did you know that engines need to be cooled to keep running? Heat inside an engine can cause the metal parts to expand, which can seize up an engine and make it stop running. It can even ruin the entire engine! Good vehicle care requires keeping its cooling system in good condition.A vehicle's cooling system circulates water and antifreeze (coolant) through the engine where it absorbs heat. It then flows to the radiator where the water and antifreeze are cooled by the air that flows over the radiator. Then it circulates back into the vehicle's engine to absorb more heat.Why shouldn't Centennial auto owners just use water? Because water boils at temperatures that are often reached inside of an engine. Steam won't cool your vehicle engine and is hard to contain within the cooling system. The antifreeze keeps the water from boiling.So why do w ... read more

Clean Fuel ? Clean Performance for Centennial Drivers

Fuel filters clean the dirt, dust and debris out of your fuel. Both gasoline and diesel-powered engines have them. The fuel filter is located in the fuel line between the fuel tank and the vehicle engine.Centennial auto owners don't need to filter their fuel because it has lots of grit in it; they need to filter it because it has some grit it in. Any dirt is bad for your engine. The cleaner the fuel, the better your vehicle engine will run.Over time, the small amounts of rust, dirt and contaminants in your fuel settle out inside the fuel tank. After about five years, this can amount to a quite a bit of sediment. This means that as your vehicle ages, your fuel filter has to work harder to screen your fuel: more sediment in your tank means more potential for grit in your fuel.The harder your fuel filter works, the more often it needs to be replaced. Check with your owner's manual to find out how often it should be serviced and how long you can expect it to last. Cen ... read more

Regular Schedule or Severe Service Schedule at Davis Automotive Repair?

Today's Davis Automotive Repair article focuses on severe service maintenance. Many Centennial drivers are not aware of them and yet there are also very vocal advocates in Colorado who think that severe service schedules apply to everyone. Somewhere between a complete lack of awareness and the dire blanket statements lies a reasonable approach to severe service maintenance at Davis Automotive Repair.To back up a little, vehicle owner's manuals have schedules for preventive maintenance: things like oil changes, transmission service and so on. They say you should change your oil after a certain distanced traveled or after so many months. Centennial drivers understand this very well. What they may not know is that there are actually two service schedules: the regular schedule and the severe service schedule. The mileage and time intervals are lower on the severe service schedule.Now when you hear 'severe service,' you may think it doesn't apply to yo ... read more

Time for Differential Service at Davis Automotive Repair?

Hello Centennial - let's talk differentials. If you have a rear-wheel drive vehicle, your differential is on the back axle. With front-wheel drive cars, the differential is up front. All-wheel drive and 4-wheel drive vehicles have three differentials - front, rear and in the middle. So you see, you've got a differential (or two or three) and it needs service now and then.What does your vehicle differential do? Well, it compensates for the differences in speed between your outer and inner wheels in a turn. Using the dimensions of a typical car, let's compare the distance the wheels travel from the start of a turn through to the completion of the turn.The inside wheel travels about 12.6 feet/3.8 meters. How much farther does the outside wheel travel? About 18.8 feet/5.7 meters – over 6 feet/1.9 meters more. This means the outer tire has to rotate 9 times in the same amount of time that the inner tire has to rotate only 6 times - so the ... read more

Stop It! You Need Good Brakes

Good brakes are obviously very important. If you've ever had your brakes go out while you're driving around the Centennial area, you'll know how terrifying it can be. Today we'll focus on how to tell when you have a brake problem and how to make good repair choices. Often, the first indication that something's wrong with the brakes is an unusual sound. It could be a squeal, chatter or grinding sound. Some brake pads have a little piece of metal embedded in them that will make a squeal or chirping sound when the brake pads have been worn down to the point that they need to be replaced. It's an early warning indicator. When you hear that sound, schedule an appointment at Davis Automotive Repair soon. Now a chattering sound is more urgent. That usually indicates that something is loose. It could be a brake pad or even the brake calipers. If one of those parts falls off, you could have some serious trouble stopping the vehicle. It would ... read more
