Keeping Your Cool (Coolant leak repair)

If there’s one thing you should pay attention to with your vehicle, it’s the temperature gauge. It’s the one that may say C---H (that means “cold---hot”).  Or maybe yours has a picture of a thermometer on it and a blue and red zone.  If you see the needle heading farther to the “H” or red area, that means your vehicle’s engine is running hotter than it normally does.

One of the most common causes of an engine running hot is a leak in your cooling system.  Maybe you’ve seen puddles of coolant under your vehicle, or you’ve smelled the coolant, either inside or outside your vehicle (it has a sort of “sweet” or fruity smell). That’s your engine giving you a warning signal that it’s time to head over to your repair facility to find out what’s going on.

Your vehicle’s coolant can leak for several reasons.  You may have hoses that are deteriorating (heat and age take their toll). It’s possible the pump that circulates coolant has developed a problem (seals and bearings can fail from heat and wear).  You may have something as simple as a bad radiator cap.  Or your radiator or heater core may have holes in it. 

If your coolant is leaking out, this can cause serious damage to your engine if you just let it go.  Your engine could get so hot that some of the metal parts start to warp.  Sometimes, your coolant can start mixing in with your engine oil.  That can result in a very expensive repair if it gets to that stage, so have it checked out before that happens.

A technician will visually inspect your coolant system, including the reservoir tank, check hoses and fittings, test the water pump, and also may pressure test the radiator.  When the problem or problems are found, they will replace the necessary parts and get you back on the road. 

When it comes to a coolant leak, finding the cause can be tricky.  But it’s important to catch a cooling system issue in time—before your engine sustains more serious damage.  Now, that’s pretty cool.

How Does Matt Davis Auto Know What to Recommend?

When you drop your vehicle off at Matt Davis Auto in Garner, they don't just poke around under your hood looking for stuff to do. Matt Davis Auto professionals have lists and procedures they follow for different types of service. First of all, your Garner service center will note the mileage on your vehicle. They'll then check to see what inspections and services the vehicle manufacturer recommends for a vehicle of your make, model and mileage. If you are a regular customer, they will also check your vehicle's history.

If the vehicle manufacturer's recommendations go beyond the services you've ordered, they'll let you know. They'll also indicate whether those services are urgent or if you can wait a while to take care of them. The Matt Davis Auto pros won't do work that you don't agree to.

They will, however, perform inspections while they're servicing your vehicle. They'll check belts, filters and fluids. They'll check your windshield wipers for wear. They'll let you know if there's an urgent problem that needs taken care of, and they'll give you a heads-up about problems that might be developing. If repairs or services are in order, you are given options based on driving needs and budget.

You can think of it like a trip to the dentist for a check-up. The dentist will check if you've had x-rays recently. If not, he'll get your permission to take new ones. Then the hygienist will clean your teeth and check your gums. At the end, the dentist comes in and inspects your teeth. You'll be told if you need any work done, about problems that are developing, and if anything is urgent. You'll be given different care options and recommendations on where to get work done that is beyond your dentist's usual purview. Then you'll be sent to the front desk for appointments and paperwork.

These procedures make sure your teeth are in good working order and that you are apprised of any problems. Then you can make a decision as to what work you want done and when. Matt Davis Auto in Garner operates the same way. They want Garner drivers to be able to make informed decisions about their car care.

Preventive auto maintenance is a lot like dental check-ups. Small problems can quickly develop into big ones. A cavity becomes a root canal. A dirty filter becomes engine damage. Skipping check-ups for either your teeth or your vehicle can lead to repairs.

Matt Davis Auto follows industry guidelines. A part is replaced only if it can no longer perform its function, no longer meets its design specifications or is missing – or if you ask for upgraded performance. Your Matt Davis Auto service advisor will recommend a part be replaced if it is showing signs that it will soon fail.

Dentists often offer services that go beyond routine care, such as teeth whitening. Service centers also offer Garner drivers help with upgrades to a vehicle. They'll know what parts are needed and how to perform the work so that safety and performance aren't compromised. You can rely on the pros at Matt Davis Auto for good auto advice.

The next time you're headed to the dentist's office, think about the vehicle you're riding in. Is it time for it to get a check-up, too?

Fears and Gears (Signs of Automatic Transmission Problems)

Automatic transmissions rule. The old days of shifting your own gears are a thing of the past for most drivers.  But automatic transmission trouble can be a big inconvenience for any driver if it comes at the wrong time in the wrong place.  Here are some signs to look out for that may mean you are having transmission issues.

When you are driving, your vehicle seems to slip in an out of gear without you touching anything.  That's what some call, not surprisingly, a "slipping transmission." 

When your vehicle shifts from one gear to the next, you hear a loud "clunk." Transmissions are supposed to be nearly silent when they shift, so that noise is telling you something is wrong. 

If you notice there's a puddle of some fluid under your vehicle, your transmission could be leaking fluid.  Try to figure out what color it is (try putting a piece of cardboard underneath to capture some of the fluid).  If it is red or brown, that's a sign it could be transmission fluid. Sometimes you may smell the transmission fluid, too; it has what some consider a "sweet" odor.

You may have a warning light that goes on when your transmission fluid is low (it could be a special transmission symbol or simply the Check Engine light).  That light could also mean the fluid is too hot or has low pressure.

If you shift your vehicle into D (for Drive) and it doesn't move or slowly engages after some delay, you may be seeing the start of a serious problem.

Of course, you don't want a malfunctioning transmission to strand you at some inopportune time. So if your vehicle is showing any of these signs, arrange a time for a technician to check it out.  Not only are broken transmissions an inconvenience, they can be a safety hazard, too.

Does My Choice in Oil Affect Change Intervals?

Oil changes are probably the most recognized service on a vehicle. Almost all Garner residents know about them. But do we know enough?

Several decades ago, oil changes were fairly standard: every three months or 3,000 miles or 5,000 kilometers. But recent advances in both engine technology and oil quality have led to longer oil change intervals.

Delayed or skipped oil changes are a problem for Garner residents because they lead to the build-up of oil sludge in your engine. Oil sludge forms when engine oil breaks down, which happens with both time and miles. Obviously, driving will take its toll on engine oil, but the oil also breaks down even as the vehicle just sits in the garage. This is why oil change intervals are listed in both time and distance traveled, and the phrase “whichever comes first” is applicable.

Oil sludge is essentially petroleum jelly. Imagine this stuff squishing around in your vehicle engine, pushing into small engine passageways and blocking passage of oil to vital engine parts, shortening your engine's life expectancy.

To prevent sludge, you have to get your oil changed regularly, as often as the manufacturer recommends. Check your owner's manual for every vehicle you own to know the interval for each one. Don't assume they will be the same.

If you tow a trailer, haul heavy loads, make a lot of short trips around Garner, usually engage in stop-and-go (or around-the-town) driving, drive in cold or hot NC weather, or drive in polluted or dusty conditions, you may need to change your oil more frequently. Check your vehicle's owner's manual for a “severe service” recommendation.

If the manual doesn't give you the advice you need, talk to your friendly and knowledgeable Matt Davis Auto service advisor. He will be able to answer any questions about preventive maintenance or vehicle care that you may have, including how often to change your oil.

Garner residents need to get the right weight and type of oil recommended for their vehicles. More and more are using synthetic oil in their vehicles. Synthetic oil typically lasts longer and is more resistant to sludge formation than conventional motor oil. But it is also more expensive. So it can be tempting for Garner residents to ask for conventional oil, but if you replace synthetic oil with conventional oil, you will have to change your oil more often to prevent sludge build-up. In the end, you're probably not saving money at all.

Also, your engine may not be designed for the conventional oil. Check your owner's manual before replacing synthetic oil with conventional.

Talk to your Matt Davis Auto service advisor for more information.
