Fuel Injector Cleaning at Matt Davis Auto

In very simple terms, a fuel injector is a valve that squirts fuel into your vehicle engine. Your engine control computer tells the fuel injector how much fuel to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute in every single fuel-injected vehicle driving down Garner roads.

Most fuel injectors for gas engines are known in the Garner automotive community as port fuel injectors because they deliver the fuel to a port just outside the cylinder. The fuel pump provides pressure needed to squirt the right amount of fuel into the engine.

A few have recently introduced gas direct injection systems on some engines. They are now available at some NC dealerships. These systems inject the gas directly into the cylinders under very high pressure – many times the pressure of port injection systems.

Although more complicated, direct injection technology promises greater power with improved fuel economy. NC motorists can expect to see more of it in the future.

High temperatures under your vehicle hood and variations in Garner gas quality cause fuel injectors to be fouled with wax, dirt, water, additives and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure.

When injectors are dirty, the fuel doesn't burn as efficiently resulting in poor fuel economy and loss of power. So it's wise for Garner residents to keep their fuel injectors clean.

Your technician at Matt Davis Auto can perform a fuel system service for you in which the fuel injectors are cleaned so that they operate properly and deliver the right amount of fuel at the right time.

Proper maintenance of your vehicle fuel system means that you will spend less on gas, enjoy strong performance and prevent repair bills down the road.

Fuel Filter Service in Garner, NC

There are a surprising number of small, inexpensive parts that can lead to expensive engine damage when they fail. It doesn't seem right.

Fortunately a lot of those things can be taken care of in routine maintenance. They may not be easy to remember because it is a long list, but your service center at Matt Davis Auto can help you know what's scheduled to be taken care of.

Some of us in Garner, NC, really don't look forward to going in for an oil change and then getting a list of the other things the manufacturer recommends.

But automotive maintenance is all about prevention and addressing small problems before they get big. Let's take the fuel filter for example.

You may not know this but the median age for private vehicles on our Garner, NC, roads is over nine years. When vehicles get older, five years or so, they've accumulated a lot of dirt and rust in their gas tanks. If that dirt gets into the engine it can cause thousands of dollars worth of damage. So somewhere between that dirty gas tank and the price of a great vacation is the lowly fuel filter: a very inexpensive part that doesn't cost too much to replace. And your vehicle will just run better too.

A clogged fuel filter can't let enough fuel through. You might notice at first that your vehicle is running fine around town but struggles or sputters on the Garner, NC, freeway or when you accelerate. Enough fuel can't get through to meet the demands of higher speed. If it gets bad enough, your engine might just shut off or not start at all, which could be dangerous.

Some fuel filters have a bypass. When they get clogged, they allow dirty fuel to move around the filter element so dirt ends up in the engine. We've already talked about how expensive that can be.

The fuel filter is even very important for newer vehicles. The fuel is still dirty even if there isn't rust in the tank. It's just that the fuel filter will need to be changed more frequently as the vehicle gets older.

How often should you change your fuel filter? Check your owner's manual. Your Garner, NC, service advisor at Matt Davis Auto can tell you as well. It's usually around 30,000 miles (50,000 kilometers) or so. Ask if it's time for a full fuel system cleaning as well. They often go hand in hand.

It's good to know that your Garner, NC, service center has your back. When you're motivated to maintain your vehicle's performance and to reduce operating costs, you'll think of Matt Davis Auto as your ally - and maybe even your memory.

Ask Matt Davis Auto: What Happens When a Serpentine Belt Breaks?

The serpentine belt is aptly named since it snakes around under your hood. It may lack its namesake's fangs, but it sure packs a wallop when it breaks.

The serpentine belt powers a lot of engine systems. It runs the alternator, which charges the battery; the water pump (on some vehicles), which cools the engine; the air conditioning, which cools the driver and passengers; and the power steering pump, which allows for easier steering. When the belt breaks, all of these systems shut down.

Okay, so maybe you can live without air conditioning and power steering for a while, but your battery can't live very long without an alternator, and when the cooling system goes down, your vehicle engine will overheat. That's why Garner drivers should never wait to get a serpentine belt replaced.

Serpentine belts are fairly inexpensive at Matt Davis Auto in Garner. And they look downright cheap when you compare them to the cost of an overheated vehicle engine, a tow truck, time lost on the road, inconvenience, and the potential safety consequences of being stranded.

Good car care means never putting off preventive maintenance. Do yourself a favor. Ask your friendly and knowledgeable Matt Davis Auto  technician to glance under your hood and give that serpentine belt a quick look-over.

Protecting Your Vehicle from Theft in Garner, NC

Every car in Garner, NC, is at risk for theft. So it's up to us to make our cars a less appealing target and more of a challenge – hopefully sending potential thieves to look elsewhere.

The National Insurance Crime Bureau recommends a layered approach to protecting vehicles:

1. Common sense
2. Visible and audible devices
3. Immobilizing devices
4. Tracking devices

Let's review each of these. One is common sense; you would be surprised how many vehicles are stolen in NC where the keys were left in the ignition with the doors unlocked. Always take your keys and lock the doors. In fact, in some places it's against the law to leave a vehicle unattended with the keys in the ignition.

And don't leave spare keys in the car or hide them outside – because a thief will find them. Garner drivers would be wise to park in well-lit areas that have a lot of foot traffic. If possible, park near the end of a row and near a light. Back your car into a parking space or your driveway to make your car more visible to passersby and harder for a thief to work under the hood without being seen.

People in Garner should know that it's important to roll up their windows completely and avoid leaving their car in public lots for a long time. If you park in a lot that has an attendant, only give them the ignition key.

Keep valuables out of sight; purses, wallets, cell phones, clothes and even change are attractive "smash-and-grab" targets. And pay to have your Vehicle Identification Number, or VIN, etched into your windows – it makes your car less attractive to a thief who wants to send your car to a chop shop.

There are lots of visible and audible devices available for Garner drivers. A steering wheel lock is highly visible and will deter some thieves. Loud alarms can alert you and others that your vehicle is being tampered with. But if your alarm does go off, be careful. Observe what's going on; get descriptions of suspicious people and vehicles, including license plate numbers.

Now, if you catch a thief in the act, call 911 but don't approach the person. Your safety is more important than the car.

And here's a great one - immobilizing devices. They actually shut off your car's electrical or fuel supply. So without a key, or knowing where the hidden switch is located, a thief can't drive your car away.

Finally, drivers can also get a tracking device that allows Garner police to track their car down and recover it quickly.

Remember, where you live, work and drive around Garner, NC, has a great impact on your decisions. If you're in an area with high theft rates, you may want to spend more money on security systems. And check with your auto insurance company to see if they offer discounts for adding any of these items.

Of course, the common sense suggestions from Matt Davis Auto don't cost anything and go a long way toward keeping your car safe from thieves.

PCV Valve Service at Matt Davis Auto in Garner

Today, we are talking about your PCV valve. Unburnt fuel is forced into the crankcase as your engine runs.  The PCV (positive crankcase ventilation) valve vents this unburnt fuel and oil vapors from the crankcase and sends it back into the air intake system to be burned in the engine.  A clogged PCV will not allow these vapors to escape. This can dilute and contaminate the oil, leading to damaging engine oil sludge. It can also cause vehicle engine corrosion, something we see occasionally at Matt Davis Auto. At high speeds on NC freeways, the pressure can build up to the point that gaskets and seals start to leak.

Back in the old days, vehicles were simply installed with a hose that vented these gases out into the atmosphere. But starting in the 1964 model year, environmental protection laws required that these gases be recycled back into the air intake system to be mixed with fuel and burned in the vehicle's engine.

This is much better for air quality and improves fuel economy also. (Budget-conscious Garner drivers take note!) The little valve that performs this important function is the PCV valve. The PCV valve lets  gases out of the engine, but won't let anything back in. Over time, the vented gases will gum up the PCV valve and it won't work well. That can lead to all of the problems I've already described, oil leaks, excessive oil consumption and decreased fuel economy.

Fortunately, it's very easy to test the PCV Valve at Matt Davis Auto in Garner and quick and inexpensive to replace. Even so, it's often overlooked because many Garner vehicle owners don't know about it. Check your vehicle owner's manual or ask your Matt Davis Auto service advisor. If this is the first time you've heard of a PCV valve, you might be in line for a replacement.

There's another aspect to the PCV system. In order for the valve to work correctly, it needs a little clean air to come in. This is done through a breather tube that gets some filtered air from the engine air filter. Now some vehicles have a small separate air filter for the breather tube called the breather element. That'll need to be replaced at Matt Davis Auto when it gets dirty.

Please ask your Garner service advisor about your PCV valve. For the price of a couple of burger combo meals in Garner, you can avoid some very engine repairs.
