Question:
My battery keeps going dead. I had it tested and it is fine - what could be the problem?

Pro-Tech Auto Repair Answer:
Well, your problem could be caused by several things. Let's start with a likely suspect: your alternator. The alternator is like a little electrical generator. It is spun by the serpentine belt on your engine and makes electricity. This electricity is used to power the electrical systems required to run your vehicle. It also powers all of your electronic accessories like your stereo, navigation, heated seats, and air fans, as well as charging all the electronics you have plugged in.

After the alternator has done all that, any electricity that's left over is used to recharge your battery. You can see where we're going: if the battery isn't getting enough electricity to stay charged the problem may have something to do with the alternator.

Now it could be that the alternator is bad – they do wear out over time. There are a number of failure points within the alternator, but in practice, it costs less to simply replace the alternator than to take it apart and repair it.

At Pro-Tech Auto Repair Inc in Corcoran, we can test your alternator to see if it needs to be replaced. We may find that the alternator tests out as being OK - but for some other reason it's not putting out enough electricity to keep the battery charged. Remember we said that the serpentine belt drives the alternator? Well problem the can often lie with the serpentine belt system.

The serpentine belt transfers power from the engine to the alternator. When the belt wears away to a certain point, it is no longer able to provide enough grip and the belt can slip on the alternator pulley so that it is not spinning enough to generate all the electricity that your vehicle needs.

A possible related cause of Corcoran a worn serpentine belt is the tensioner pulley. This pulley provides tension on the serpentine belt so that it is tight enough to spin the alternator and other accessories. When the belt is too loose, it can slip on the alternator pulley and, once again, not enough electricity is made.

So, when you battery is going dead - test it. If the battery is still good - test the alternator. If the alternator is still good - inspect the serpentine belt and belt tensioner. Chances are good that your service center or the team of friendly and knowledgeable staff at Pro-Tech Auto Repair will get to the root of your problem.

Wiper Blade Design

Wiper blades may not be the most exciting topic for most drivers – but they are pretty important. Most of us Minnesota residents have had an experience when a sudden snow or rain storm hits while we're driving; then when we turn on the wipers – nothing but streaks. This can be especially disconcerting at night when the glare of on-coming headlights distorts your vision.

Simple answer: change your wiper blades BEFORE they fail. Check them out every couple of months just to see how they are working. Of course, the more you use your wipers, the sooner they'll wear out. Areas with lots of storms or those who drive a lot in MN where there are bugs and road grime will use their blades more.

But even when you're not using your blades, they are exposed to sunlight, ozone, soap, and extreme hot and cold MN temperatures which lead to deterioration. Your blades can just rot away and fall apart before you need them. Of course, using your wipers when the blades are torn can lead to scratches in your windshield. You don't want to risk windshield replacement over the cost of a couple of wiper blades.

Now let's talk about wiper blade upgrades. You can upgrade both the design and the wiper material. Let's start with the material. Traditional black rubber blades do a great job of clearing your windshield when they are new. Over time all of the conditions mentioned above damage them and degrade their performance. Silicone blades are far less affected by environmental conditions and will simply perform better for a longer time.

There are two elements to the design. First, the wiper blade itself: Some have a single wiping edge. Others have multiple edges – kind of like a multi-blade razor. The idea is to maximize wiping power during both swipes of the blade.

The other design element is with the wiper frame. This is the structure that applies pressure on the blade as it passes over the windshield. A conventional frame has four to six contact points on the blade. These apply pressure used to clear water and snow. A beam frame provides uniform pressure along the entire surface of the wiper. Their shape catches the wind passing over the vehicle to provide additional downforce to help

Road Construction

As we say in Minnesota there are 2 seasons, winter and road construction. Well road construction is here.
The city of Corcoran will be starting a sewer and water project xx/xx/2016, which will require tearing up the road in front of Pro-Tech Auto. We have been assured that the interruption will be kept to a minimum, whatever that is?
There are 2 directions that you can us from. The first is entering from County road 10 or (Bass Lake Rd.) and the other is entering from County road 116 by the Corcoran Bottle shop and Westside Tire. Depending on how far the project has moved along will determine the best route. When making an appointment we will advise you of the best route. We also may have access through our neighbor behind us, Total Control Solutions @ 20175 Co. Rd. 50 if construction is directly in front of our driveway.
No matter what we are open for business and hope the inconvenience for our customers is minimal and bearable. We greatly appreciate your patronage and understanding. Things will be better when all done.
Thank you again,

What You Need Know About Shocks and Struts
Jul 23rd, 2016
Shock absorbers and struts last a long time and wear out slowly. So they’re easy to take for granted, but your shocks and struts do a very important job so you need to pay attention to them. They keep your tires on the road; and your tires are what connect your vehicle to the road and allow you to safely handle your car through turns, over bumps and even stop in time.
When your shocks and struts are worn, your tires bounce excessively over bumps. Your vehicle will wallow through corners; your front-end will dive when you stop; and the rear-end of your car will squat when you accelerate. All this hurts your ability to control your vehicle. And your ride just isn’t as comfortable.
Worn shocks or struts cause excessive tire wear so you’ll have to replace your tires sooner than you should. Worn shocks and struts will also stress other suspension and steering parts causing them to wear prematurely. Struts are actually a major structural component of the suspension system – there’s a lot riding on them.
Replacing worn shocks and struts saves money in the long run – and of course you can’t really put a price on your safety and that of your passengers. At Pro-Tech Auto Repair we generally recommend replacing shocks and struts at 50,000 miles or 80,000 kilometers.
When it’s time for new shocks or struts, we’ve got you covered at Pro-Tech Auto Repair Inc. We can give you back the ride and handling of a new vehicle. And if you have special needs we can help you there too. Pro-Tech Auto Repair has premium shocks and struts that’ll improve your performance. We can even help you with upgraded, heavy-duty shocks that’ll give you the confidence you need to handle those big towing or hauling jobs.

Simple Answers from Pro-Tech Auto Repair for Cooling System Service

Question:
My engine never overheats. Why should I get a cooling system service?

Pro-Tech Auto Repair Answer:
That's a really good question for drivers to ask, because if you don't have the full answer you may end up in trouble. It would seem that if your engine is running at the proper temperature that everything must be OK. But the fact is that engine overheating is the most common cause of engine mechanical failures. So how do you get from everything is just fine to suddenly overheating and potential engine damage?

Truth is, it is not a sudden process, but it is an invisible one. Your engine coolant circulates through your engine where it absorbs heat and then flows through the radiator where it is cooled – and then back to the engine again. As long as the coolant is able to flow freely – and there are no leaks – then the coolant can do its job. This is the point where drivers have to look deeper.

The cooling system is an environment: very hot, with a number of reactive materials like various types of metal, plastics and rubber. Over time the coolant becomes corrosive. Small pieces of metal and other materials flake off and circulate in the coolant. As these bits material start to clog up the small passages in the radiator, they restrict the coolant flow, leading to overheating. Corrosive coolant can actually eat away at the system and cause leaks as well.

Now new coolant is full of anti-corrosion additives. These additives neutralize the reactions that lead to corrosion. The additives are eventually used up, leaving the cooling system unprotected.

This is why your vehicle manufacturer and the team at Pro-Tech Auto Repair give a recommendation for when your cooling system should be serviced. Your friendly and knowledgeable pros at Pro-Tech Auto Repair can also test your coolant for freeze point and PH to see if it needs to be replaced (if you've added straight water to the system these numbers will be off). You need to get fresh coolant in there to continue to protect against corrosion.

So if you’re a driver who've gone beyond the recommended service interval should take care of this maintenance service to prevent unnecessary repairs down the road.

Suspension Problems
Jun 11th, 2016
Let's talk about your suspension – you know, the system that connects your wheels to your vehicle, controls your handling and delivers a good ride as you cruise around. Your suspension is critical for proper steering, stopping and stability.

Hey, it's a rough world out there in – every time you hit a pothole, a bump or an object in the road, your suspension system has to absorb the impact and maintain control.

As you can imagine, your suspension has a lot of joints and pivot points that allow your wheels to move up and down over bumps and to turn as you steer. These parts include ball joints, tie rod ends, the pitman, idler arms and the control arm bushings. And they simply wear out over time.

When a joint or other part is worn the suspension parts don't fit together as tightly as they should. The handling and steering has a loose feel and you may hear strange noises. Your tires will wear unevenly because they're bouncing down the road a little off kilter.

A loose joint has the effect of stressing other suspension components so they wear out faster than they should. Sometimes a suspension part can be bent from hitting a rock or curb or by slamming into a big pothole.

When your service technician at Pro-Tech Auto Repair inspects your vehicle, he'll look for signs of suspension problems: things like uneven tire wear, excessive play in suspension components and other visible damage. He can replace the worn or damaged parts and restore safe handling.

It's a great idea to take care of these problems right away before they become more expensive to repair. And nobody likes to see a tire that should last for several years get worn out in a matter of months because of a bad suspension part.

Let us help you keep your vehicle operating safely. And saving some money on repairs and tire replacement is a good thing too.

At Pro-Tech Auto Repair Inc in Corcoran MN, 55340 we install quality NAPA replacement parts. You can reach us locally at 763-420-3060.

Using the Proper Grade of Gas
There are a lot of misconceptions about fuel grades – and by fuel grades I mean the octane rating. With names like “Standard”, “Super”, “Plus”, and “Premium” it’s no wonder that people associate the octane rating/grade with quality. Octane ratings are expressed as a number that typically ranges from 87 to 91 at the pump. The number does not mean “better” but rather signifies the appropriateness of a particular grade of fuel for a particular engine.
Octane is a measure of gasoline’s ability to resist igniting before the spark plug goes off. Gasoline and air are compressed in the engine’s combustion chamber. When the pressure reaches a certain point, the gas and air mixture will spontaneously combust. You don’t want that to happen; you want the spark plug to ignite the fuel at precisely the right time. When the gas combusts prematurely, the piston will try to go down while it is still being pushed up by the crank shaft and you will hear a pinging or knocking sound. That sound is metal stuff banging into other metal stuff when it’s not supposed to. As you can imagine, this can lead to expensive damage.
Because engines have different designs, they have different compression ratios. An engine with a higher compression ratio needs gasoline with a higher octane rating to prevent premature combustion. Also, turbocharged or supercharged engines have higher pressure in the engine and often require higher octane gas. The bottom line is that your vehicle has a recommended octane rating – often on a sticker in the gas cap area – and you should always use at least the octane number recommended. Using a lower octane rating than recommended could cause engine damage. Using a higher octane rating than recommended will not have any discernable power or efficiency benefit in modern engines.
Now, just because the octane number doesn’t measure quality, that doesn’t mean there isn’t a quality difference in gasoline. The government mandates that all gas have a minimum level of detergent added to keep the engine and critical fuel system and emission components clean and operating efficiently over the long haul. Top tier gasoline will have many times the minimum level of detergent. To give you an idea of how important that is, all U.S. automakers use top tier gasoline in their government mandated 100,000 mile durability tests. Good quality fuel is critical to long life of engine components.
No matter what kind of gasoline you use, there will be some carbon build up on your valves, pistons, fuel injectors, etc. This is especially prevalent on the intake valves of the GDI (gasoline direct injection) engines that are found in more and more vehicles because the gas is injected directly into the combustion chamber and the detergents in the fuel do not wash over the intake valves. A professional fuel system cleaning is needed to clean and restore the efficiency of your fuel system and to keep your fuel economy up.
Ask your Service Advisor at Pro-Tech Auto Repair if it’s time for a professional fuel system cleaning.
