Scottsbluff Auto Repair

Today we want to talk about a system in our vehicles – the cooling system. It's one of those things that Scottsbluff auto owners don't give much thought to until it fails and then they're stranded by the side of a road in NE.Cooling systems fail more often than any other mechanical system – usually because of neglect. Don't you hate it when something breaks and you could have done something to prevent it?The good news is that if Scottsbluff drivers take care of their cooling systems, they can keep working for the life of their car.Here at Twin City Auto in Scottsbluff, we emphasize preventive maintenance services like replacing your coolant according to the factory schedule. But the various parts that make up the cooling system need attention too. The major components of the cooling system are the water pump, freeze plugs, the thermostat, radiator, cooling fans, the heater core, the pressure cap, the overflow tank and the ho ... read more

If you park your vehicle outside, you are exposing it to all sorts of critters that would love to use it for nesting, food storage and shelter.  There are plenty of pictures online of people who've discovered there was more than an engine under the hood.  In one case, the driver of an SUV started to smell a slight burning odor when she was driving.  Turned out to be 200 walnuts and a lot of grass had been stored there by some industrious squirrels preparing for the upcoming cold weather.  The SUV owners had their vehicle inspected not long before this happened, but it doesn't take some animals long to set up house in what they think is the ideal spot to make their winter home.   Obviously, that can create problems.  Squirrels, mice, rats and other small animals can chew through hoses and wires.  Plus what they store as food and nesting material may prevent engine parts from moving the way they are supposed to.  Imagine a radiator fan that wo ... read more

Nobody has to tell you that computers are a part of so many things in our lives.  Smartphones, kitchen appliances, vacuum cleaners, televisions.  You name it—it has a computer in it.  And your vehicle is no exception. The earliest cars relied on the technology of their time, and there was no such thing as a computer.  But now, it's not unusual for a vehicle to have as many as 150 computers in it. They perform a variety of functions. An important one is diagnosing your vehicle's problems.  There are various sensors throughout modern vehicles that measure thousands of data points.  When something is not working correctly, they send a signal to another computer that stores that information. The data can be read by someone who has a special computer that plugs into a port in your car.  It displays certain codes that help technicians track down the culprit.  But it's not just the diagnostics that are computerized.  Everything from your vehi ... read more

With the weather getting colder, you might be tempted to start your vehicle up, let it idle for 15 or 20 minutes and then get in the nice, cozy cabin.  Some vehicles offer remote starting that let you do that from the comfort of your home or apartment.  But is letting your vehicle idle like that good for it? Manufacturers say it doesn't harm the vehicle.  They say it's because modern vehicles are made differently from those in the past.  Just about all newer vehicles employ fuel injection which uses computers to adjust the amount of gasoline that goes into the cylinders.  The engine gets only the fuel it needs, taking conditions into account. Older vehicles, on the other hand, used to use carburetors.  When you started a cold engine, the carburetor wasn't able to adjust the gasoline amount depending on conditions.  Some of the gasoline would mix with oil and the pistons wouldn't get the same lubrication as they would with undiluted oil. So yes, you ca ... read more

There's one fluid in your car you are always careful to keep at a certain level: the fuel. If you don't have fuel, you're not going anywhere.  Your vehicle has other fluids which are vitally important to proper and safe operation, too.  So, here's a "level" headed approach to those "other" fluids. Engine oil.  This one's probably the most important fluid to maintain at the proper level. Without enough oil, you'll wear out your engine prematurely.  Sometimes vehicles have warning lights on the dash that will tell you to get your oil checked.  Don't ignore that one; get it checked immediately.  Certainly don't go on a long trip at high speeds with your oil level low. Oh, and it's not good to have too much oil in, either. Our pros at Twin City Auto can advise you on oil levels and tell if you if you should be concerned about abnormal fluctuations. Windshield washer fluid.  OK, this is one you probably know about.  You certainly miss it when it runs ... read more

Your vehicle's engine makes a lot of heat when it's powering you down the road, so it needs a way to get rid of that energy.  That's why your vehicle has a cooling system, complete with a radiator and one or two radiator fans, also called cooling fans.  Those fans make sure air keeps moving across the radiator so that the heat stored in the coolant can be dissipated outside when the vehicle is stopped or not traveling fast. Radiator fans can develop problems and can stop working properly or stop working altogether.  Some signs to look for? If you're driving slowly and idling and you see your temperature gauge moving toward the red or hot zone, that could spell trouble.  Another thing you may notice when a radiator fan is failing is that there may be a loud noise coming from the engine compartment. There are two types of radiator fans.  One is mechanically connected to the engine and uses the engine's rotational energy to turn it.  The other is an electric ... read more

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 Twin City Auto. At high speeds on NE 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 an ... read more

You've probably noticed how much easier it is to see when you're driving in the daytime as opposed to at night. It's one of the main reasons about half of all fatal vehicle accidents happen when it's dark. That's why it's important that your vehicle's headlights are in top condition and working the way they should.  That means that they're aimed correctly and producing the amount of light they are intended to produce. For many years, headlights were a standardized size and shape.  They were what is called a "sealed beam," and when you needed to replace one, it was pretty simple.  You just took the old one out and plugged a new one in.  But now there are hundreds of different types of lighting systems on vehicles, producing light with such illuminating technology as light-emitting diodes (LEDs), halogen bulbs, high-intensity discharge (HID) bulbs and more.  Some vehicles have systems that turn your lights in the direction you turn your steering wheel so you can ... read more

In the hot weather, seeing steam coming from the engine compartment is something we all dread.  No one wants that to happen to them. But if you know the signs of overheating and how to deal with it, you may be able to reduce the risk of damage to your vehicle, maybe even prevent getting stranded on the road. Besides the steam coming out of the engine compartment, here are a few signs of overheating.  Your vehicle has a heat gauge that may have a needle that can go into a red zone or up to the "H" (for High) position.  You may smell odors, perhaps a burning (could be hot oil) or a sweet smell (engine coolant leaking).  When you encounter any of those signs, you know you have to do something to keep the engine as cool as possible to avoid potentially catastrophic damage.  Turn off the air conditioning and turn up the heat.  While that last part may sound odd, it helps draw heat out of the engine.  If you can do it safely, pull off the road to a spot awa ... read more

Whether or not your exterior light bulbs are all working probably is not at the top of your list when you think about your vehicle.  But those exterior lights are more important than you think, and they're vital to your safety and that of other drivers near you. Headlights are important.  Not only do they help you see safely down the road at night, they also help oncoming drivers know that the vehicle they're approaching is not a motorcycle.  Both headlights should be working properly and aimed so that they don't blind other drivers. Taillights are also important for a few reasons.  They tell drivers what your intentions are (changing lanes, turning, stopping).  So, the bulbs back there must be all in working order for maximum safety. Ditto for the front turn signal lights.  They alert oncoming drivers to your lane changes or turns (if you use your turn signals!).  Some side mirrors also have turn signal bulbs in them. There are a few other important ... read more
