If someone asked you what gas made up the largest portion of the atmosphere, what would you guess? Well, it's not oxygen; it only makes up 20.9 percent.  But since we're talking about oxygen, you should know that your vehicle uses oxygen sensors to make sure your engine is running the way it should. The oxygen sensors measure how much oxygen is in your exhaust.  If there's too much, it means there's a problem with the mixture of fuel and air.  The sensor sends signals to computers in your engine and adjusts the mixture so it maximizes performance and efficiency.  It does this constantly.  Many vehicles have multiple oxygen sensors.  Some have one close to the engine, another close to the muffler.  Two measurements are better than one since they allow readings to be more accurate.  You may have a vehicle with a dual exhaust, so you'd have twice as many oxygen sensors. Your oxygen sensors can fail.  One thing that can damage them is contaminat ... read more

Driving on bald tires is like playing roulette. Though you may be fine today, eventually your luck is going to run out.The Feds don't have any laws for tread depth, but 42 of the states, and all of Canada, do have regulations. They consider 2/32 of an inch to be the minimum legal tread depth. Two other states, including California, consider 1/32 to be the minimum and six states have no standards at all. Call us at Mackert Automotive LLC; (just call 2538513307) to find out what your requirements are in the GIG HARBOR, WA, area.Since 1968, U.S. law has required that a raised bar be molded across all tires. When tires are worn enough that this bar becomes visible, there's just 2/32 inch/1.6 mm of tread left. But does that older standard give GIG HARBOR vehicles enough safety?Consider this: Consumer Reports recommends tire replacement when tread reaches 4/32 inch/3.2 mm. And the recommendation is backed by some very compelling studies. Now before we go into the studi ... read more

When you start up your gasoline engine car, you may not know that it's using the same ignition principles as it has for decades.  You have spark plugs that require enough power so a spark can jump across a gap at its tip.  Years ago, a vehicle's 12-volt system had to produce 15,000-25,000 volts to do that, so engineers came up with something called an ignition coil that bumps up the voltage. It also has to be done at just the right interval called timing. The first systems had a distributor, a mechanical device with a rotating disc that switched the power to the ignition coil on and off.  That higher voltage then was sent to the spark plugs at the correct time interval. But the mechanical "points" had to be replaced and adjusted every 12,000 miles/20,000 kilometers.  Engineers later replaced the switching mechanism with solid state ones, but they still needed replacement after 120,000 miles/200,000 kilometers. The next evolution came in the 80's when the distributor ... read more

Today we want to talk to GIG HARBOR drivers about timing belts. They're something that many drivers don't know much about and yet your vehicle won't run if it's broken – and it could cause many thousands of dollars damage if it does break. A broken timing belt is usually a tale of woe. Even though timing belt replacement is scheduled in the owner's manual, it's not the kind of thing that most GIG HARBOR area auto owners remember because it's not well understood.Let's review what a timing belt does. As most know, the engine's power is generated in the cylinders. A piston rides up and down in the cylinder. During the first down stroke, an intake valve at the top of the cylinder opens and air and fuel is drawn into the cylinder. Then the piston returns to the top, compressing the fuel and air mix. At the top, the spark plug fires, igniting the fuel, pushing the piston down in the power stroke. As the piston once again returns up in the final stroke of the cycle, an exhaust valve op ... read more

If your windshield wipers are streaking and chattering when you turn them on in the rain or snow, it's time for a little "blade renewal." And when it comes to new wiper blades, there are some new designs that are worth a look. One of the latest is called the beam blade.  It's different than conventional blades you might be used to.  Instead of a metal frame and a rubber blade that slides in the frame on a track, the beam blades have an enclosed spring-steel band that allows the rubber wiper to conform to the windshield glass shape much more tightly.  There are some key advantages to beam blades, which is why many vehicle manufacturers are making them standard on their latest models.  For one thing, they work well in all weather conditions, including the heat of summer and the icy, snowy cold of winter.  Since there is no separate frame, snow and ice can't form in gaps like conventional wipers and prevent the blade from clearing your windshield.  Many beam ... read more

You know how heavy your engine and transmission are, so you can imagine how tough the parts that hold them onto your vehicle's sub-frame must be.  Not only must they support the weight, they also have to isolate vibrations and noise from the passenger cabin.  Pretty tall order, wouldn't you say? The parts that face that task daily are called the motor mounts, or engine mounts.  They are usually made of rubber with steel brackets.  Others contain a liquid for vibration and sound isolation.  Most vehicles have three or four motor mounts, and while rubber or hydraulic liquids do a good job of damping the vibrations from the engine, they also have their limitations.  The problem with rubber is that it gets old and brittle.  Plus, if there's an oil leak anywhere in your engine and oil gets on the rubber motor mounts, rubber will deteriorate even more quickly.  As for the liquid motor mounts, they can develop leaks and stop working.  Here are sign ... read more

The Check Engine Light strikes fear into the hearts of some GIG HARBOR drivers, and is totally ignored by just as many. Just what it means is a mystery to most people. Let's get the urgency issues out of the way first. If your Check Engine light is flashing, that means that something is wrong that could cause engine damage. Naturally, you need to get that taken care of right away. If your check engine light is flashing, you shouldn't drive at high speeds, tow or haul heavy loads. Take it easy all the way to your GIG HARBOR service center. If the light is glowing steadily, you should keep an eye on it for a day or two. If the light doesn't go off, schedule an appointment with your friendly and knowledgeable pros at Mackert Automotive LLC to get it checked out.Some more information on how the Check Engine light works may be helpful for GIG HAR ... read more

A vehicle's suspension system is tough. It can last for years and after lots of driving for GIG HARBOR drivers. But it can be damaged quickly by hitting a pothole, curb or rock, and it can wear more quickly if you frequently drive off-road or on bumpy roads. A workhorse vehicle — one that hauls heavy loads — is also going to be hard on its suspension system.Because the useful life of your suspension system contains these elements of unpredictability, it is important for GIG HARBOR drivers to have them inspected periodically. Worn, broken and missing parts can be identified during an inspection at Mackert Automotive LLC . An ineffective suspension system will decrease the driver's control over a vehicle, so when it is damaged it frequently leads to the worst kind of vehicular damage — dangerous accidents.The suspension system is composed of springs and shock absorbers (or shocks). Springs suspend the weight of the vehicle above its axles. They allow the vehicle to ... read more

Hello, welcome to Mackert Automotive LLC. Today's focus is batteries. It seems like everything in GIG HARBOR runs on batteries. Of course, the batteries we're most concerned with here at Mackert Automotive LLC are those in our customer's vehicles. Just like the batteries in our smoke detectors or TV remote, they wear out and need to be replaced . This can be thought of as the power output used to start a cold vehicle engine. The number of cold cranking amps you need depends on your vehicle and where you live in WA, specifically how cold it is. (Many GIG HARBOR drivers have first-hand experience trying to start their car on a cold winter morning.) The two factors are that the colder your vehicle's engine is, the more power it takes to turn the engine over to get it started. It has all that cold, sluggish oil to contend with.The other factor is that the chemical reaction in the battery that creates electrical energy is less efficient when the temperature dips ... read more

Whether we're trying to save money, save gas or save the environment, most of us GIG HARBOR drivers have an interest in decreasing fuel consumption. We've all heard about ways to save money on gas in WA, but does it really add up to much? How much can we boost our fuel economy through preventive maintenance and more courteous driving?The US government has a website that actually answers that question. Let's look at some of the data and find out if any of these fuel-saving ideas are really worth the effort. We've all heard that a tune-up can improve gas mileage. It turns out that it can save us 4% at the pump. At $3.50 a gallon, that's 14¢ per gallon in savings, and at $4.00 a gallon, that's a 16¢ per gallon savings.Other common repair items can also save you at the pump. For example, if your oxygen sensor is faulty, it's not delivering the information to your engine's computer that allows it to calculate the right fuel-to-air ratio. The result? The ... read more
