Smart Oshkosh Drivers Protect Against Overheating
Posted October 30, 2014 12:00 PM
Engines get hot when they run. This heat can build up and damage vital engine parts, so engines need a cooling system to keep them running. Cooling system failure is the most common mechanical failure in vehicles. This is unfortunate, because these failures are usually easy for Oshkosh drivers to prevent.
The radiator is the best-known and most recognizable part of the cooling system. Hoses filled with coolant (also known as antifreeze) connect the radiator to the engine. The coolant draws heat from the engine and then flows to the radiator. Air passing through cooling fans on the radiator cools the coolant. The coolant then cycles back into the engine to start the process over again.
The most critical component of the cooling system, however, is the coolant itself. A mixture of water and coolant/antifreeze helps keep it both from freezing and from boiling away. Either can result in serious engine damage.
Different engines require different types of coolant/antifreeze. The owner's manual will list what kind a vehicle requires. Using the wrong type or mixing different types of coolant/antifreeze may void the warranty on the cooling system and may damage it as well.
Insufficient coolant can lead to engine failure. Coolant levels need to be checked regularly and topped off as necessary. If coolant levels drop quickly or consistently, the cooling system should be inspected for leaks. Coolant/antifreeze contains additives that protect the radiator and other coolant components from rust, scale and corrosion. Over time, these additives are depleted, so it is necessary for Oshkosh drivers to replace coolant at specified intervals. Changing coolant should be part of routine preventive maintenance for any vehicle.
This service is often ignored, though, since old coolant still cools the engine. Vehicle owners don't realize there is a problem until the system fails. They are left with major repairs and possibly a damaged engine, which could have been prevented with a cooling system service at Auto Authority LLC in Oshkosh.
If your vehicle sends a warning message to check its coolant or if the temperature gauge is reading in the red or hot zone, then the cooling system needs serviced. This service is critical and should not be put off since the potential for damage is high.
In an emergency situation, water or antifreeze can be added to your vehicle so that it can be driven to a service center for proper car care. For this reason, your owner's manual contains instructions for how to top off insufficient coolant – allow 45 minutes for the engine to cool before attempting to add coolant or water. However, the fluid should be added to the coolant overflow bottle, not to the radiator itself. Removing the radiator pressure cap can result in severe burns.
Topping off in an emergency, however, does not fix the problem. The vehicle should immediately be taken to Auto Authority LLC in Oshkosh where they can inspect the cooling system, repair any leaks and clean it if necessary. They can identify what caused the emergency situation in first place and ensure it doesn't happen again.
Regular maintenance of a vehicle's cooling system is just good auto advice for Oshkosh drivers. Cooling system service is relatively inexpensive and doesn't take long at Auto Authority LLC. Lack of it, however, can put a vehicle in the scrap heap.

How Much is Enough for Oshkosh Auto Owners? Tire Tread Depth
Posted October 24, 2014 12:00 PM
Most Oshkosh drivers know that tires wear out and that the wear has to do with tread depth. Most of us have heard that “bald” tires are dangerous, but most of us picture a tire with no tread at all when we think of a bald tire. And when we take our vehicles in for preventive maintenance, the technician tells us they're need to be replaced long before all the tread is worn off. Just how much tire tread wear is too much? And how can you tell? Tires are and their condition is important to the safe handling of a vehicle, so it's for Oshkosh vehicle owners to know the answers to these questions.
First of all, it's important to understand that there may be a legal limit to tread wear. If your tires are worn past this limit, you have to replace them to be in compliance with Wisconsin auto safety laws. That's why measuring your tread wear is part of a vehicle safety inspection.
In some jurisdictions, tread must be at least 1.6 millimeters or 2/32 of an inch thick. This standard has been in effect since 1968. But this standard has recently been called into question, and some Wisconsin professionals are arguing that it be changed.
The safety issue that has brought this standard under scrutiny is the ability of a vehicle to stop on a wet surface. When a vehicle has trouble stopping, most Oshkosh drivers immediately look at the brakes as the source of the problem. But tires are crucial to safe stopping distances because they provide the traction required in a stop.
A tire's contact with the road surface creates traction, which allows for effective braking. On a wet surface, a tire only has traction if it can get to the road's surface. So tire tread is designed to channel water out from under the tire to allow it to stay in contact with the road. If the tire can't shift the water, then it starts to “float.” This condition is called hydroplaning. It is very dangerous for Oshkosh drivers since the vehicle won't stop no matter how hard the driver presses the brakes. Steering control is also lost.
A recent study tested the stopping ability of a passenger car and a full-sized pick-up on a road surface covered with only a dime's depth of water (less than a millimeter). The vehicles were traveling at 70 mph (112 kph) when they stopped on the wet surface. At 2/32 (1.6 mm) tread depth, the stopping distance was double that of a new tire. The passenger car was still traveling at 55 mph (89 kph) when it reached the stopping distance it experienced with new tires.
Let's suppose that you're on a busy Oshkosh road in a light drizzle and a vehicle stops suddenly in front of you. You just bought new tires and you brake hard, missing the vehicle with only inches to spare. If you hadn't bought those new tires, you would have crashed into that vehicle at 55 mph (89 kph). That is a major difference.
What if your tires had a tread depth of 4/32 (3.2 mm)? You would have crashed into that vehicle at 45 mph (72 kph). Still not a good situation. But it's better.
Now what if you were driving that pick-up truck? You wouldn't have missed that vehicle in the first place, and you would have crashed at higher rates of speed in both of the other scenarios. The heavier your vehicle, the longer its stopping distance. It's a matter of physics.
The results of this test has led Consumer Reports and others to ask that the standard for tread wear be changed from 2/32 (1.6 mm) to 4/32 (3.2 mm). The increased standard will improve safety on the road and save lives here in Wisconsin and nationally.
Of course, until the standard changes, you'll have to decide whether you'll be willing to replace your tires a little sooner.
You can use an American quarter to tell if your tread wear is down to 4/32 (3.2 mm). Place the quarter into the tread with George's head toward the tire and his neck toward you. If the tread doesn't cover George's hairline, you're under 4/32 (3.2 mm). With a Canadian quarter, the tread should cover the digits of the year.
You can measure the 2/32 inch (1.6 mm) tread wear with a penny. If the tread touches the top of Abe's head, it's at 2/32 (1.6 mm). Tires are super important when it comes to vehicle care. But their condition has a major impact on safety. We need to decide whether to sacrifice safety for economy. Keeping our tread wear above 4/32 in (3.2 mm) is good auto advice.

The Right Fluids for Your Vehicle
Posted October 17, 2014 12:00 PM
The current vehicles in the market have over a century of engineering behind them. They have evolved into complex and powerful machines. Developments in their engines, however, have coincided with advances in many other vehicle components, including the fluids.
It's up to people in Oshkosh to always use the right type of fluid for their vehicle. Your service advisor and your owner's manual are resources for auto advice on exactly what types of fluid your vehicle needs. Improper fluids can damage your vehicle and void your warranty.
Some of the fluids that have changed significantly in recent years are cooling system fluid, brake fluid, transmission fluid and motor oil. Each of these comes in many varieties now, and it's hard to know exactly which one your vehicle needs.
Cooling systems were once made of iron, steel and rubber. One coolant could be used to protect all of these materials. But new cooling systems have components made from a variety of metal alloys and several kinds of plastic, and coolants now contain additives that protect these various materials from corrosion. Since the materials vary among manufacturers, they require different additives, which means there are now several coolants on the market. The type of coolant your vehicle needs depends on the materials used in its cooling system.
Most vehicles used to require DOT 3 brake fluid. But now many vehicles need DOT 4 or DOT 5. Some Oshkosh drivers mistakenly think the higher numbers reflect an increase in grade—that DOT 4 is somehow better than DOT 3. But the truth is, the numbers represent variations in formulation. The different formulas have evolved to meet the demands of newer and better brake systems. For a long time, transmission fluid came in two varieties: regular and friction-modified. But transmissions have come a long way recently and so have the fluids that protect and lubricate them. There are several new types of fluid on the market, but your vehicle is designed for just one of them.
Of all the automotive fluids, motor oils have experienced perhaps the greatest advances in engineering and technology. A number of new weights and formulations have recently been developed to meet the needs of modern engines, which have more parts and tighter tolerances than ever before. Engines have become more sophisticated and complicated, but they have also increased in power and fuel efficiency. Despite these changes, Oshkosh vehicles still need them to be highly durable.
That's the job of motor oil. Motor oil still has to perform its original function—lubricating and protecting the engine. It is formulated to help clean the engine as well. Modern motor oil also has to be thin enough to penetrate small engine passages yet still be resistant to vaporization.
Specialized motor oils have also been developed for high-mileage vehicles. If your vehicle has 75,000 miles/120,000 km or more on it, you might consider switching to one of these motor oils. They contain extra detergents that help clean older engines, additives that condition seals and gaskets that can become brittle with age. High-mileage motor oils come in weights and types just like regular motor oils, and Oshkosh drivers should match the proper weight and type of high-mileage oil to their vehicle in the same way you would regular motor oil.
Over time, vehicles have developed in complexity and variety, and their fluids have developed as well. Each vehicle is matched to a set of fluids that meet its specific requirements. Wisconsin vehicle owners should take care to learn their vehicle's fluid requirements before topping off at home. A large part of preventive maintenance for Oshkosh drivers is making sure your vehicle's fluids are clean and adequate, but they must be the proper type as well. As our vehicles become more sophisticated, car care becomes more sophisticated as well.
Learning about proper fluids for your vehicle will help you maintain its performance and prolong its life. Talk to us at Auto Authority LLC in Oshkosh.

Keep Your Cool in Oshkosh
Posted October 7, 2014 12:00 PM
Oshkosh drivers rely on their vehicle's coolant system to keep their engine cool. Coolant (also called antifreeze) mixed with water flows through your vehicle engine and absorbs heat. The mixture then flows out to the radiator where it's cooled by air flowing over the radiator. From there the coolant/water mix circulates back through the engine to absorb more heat.
There's a reason we mix coolant and water. Water alone actually does a good job transferring heat from the engine. The problem is that water boils at a temperature that's easily reached inside your vehicle's engine, so it can turn to steam which does not conduct heat as well and is harder to contain.
Also, if it's freezing outside in Oshkosh, the water in your engine could freeze while your vehicle is sitting out in the Wisconsin cold.
So, if you remember your high school chemistry, you'll know that a mixture has both a higher boiling point and a lower freezing point than either component alone.
Coolant, or antifreeze, is specially formulated to keep your engine safe in a wide range of environmental and operating temperatures in and around Oshkosh.
Whenever your vehicle is running, the coolant in the cooling system is working to keep your engine from overheating. When it's cold outside, the coolant acts as antifreeze to keep the fluid from freezing in your engine.
All that exploding fuel in your engine creates a lot of heat. Without coolant, the metal vehicle engine parts would expand so much that the engine would seize up and stop running. The parts could be broken or warp so badly they would have to be replaced. It could even be so bad that the whole vehicle's engine is ruined and has to be junked.
This is why it is critical that Oshkosh drivers check coolant levels frequently and have their vehicle's cooling system inspected for leaks. Also your vehicle has a maintenance requirement for draining and replacing your coolant. These recommendations can vary widely, so check your owner's manual or ask us at Auto Authority LLC in Oshkosh.
The reason Oshkosh drivers need to change the coolant is that it has additives in it to protect the cooling system. As you can imagine, with all the heat, the cooling system's a pretty harsh environment. The additives keep the fluid from becoming corrosive and damaging the radiator and other vehicle cooling system components. Over time, the additives are depleted and the coolant just has to be replaced.
Many Oshkosh auto owners ask our advisors at Auto Authority LLC why there are different colors of antifreeze. It is very important that you use the correct type of antifreeze. The different types of antifreeze – or coolant – are different colors so you don't mix them up.
They use different materials to make the cooling system, and they require different types of antifreeze to protect them.
So check with us at Auto Authority LLC in Oshkosh or your owner's manual for the right kind because using the wrong coolant can void the warranty for your vehicle cooling system.
