Saving Lives in Cold Spring with Tire Pressure

All new passenger vehicles on our Cold Spring, MN, roads now have tire pressure monitoring systems – TPMS for short. They are designed to alert you if your tires are underinflated. Since they are fairly new, a lot of people have questions about them.

First off, the most important thing is that you still need to check your tire pressure every week – or at least every time you gas up. The TPMS system alert comes in when your tire is 20 percent below the factory recommendation. So if the recommended pressure is 34 pounds per square inch, the TPMS warning won't come on until the pressure is at 28 pounds. That's significantly underinflated, enough to raise safety concerns.

The worst is tire failure. A severely underinflated tire can overheat and fail. Also, handling degrades to the point that you may not be able to steer out of trouble. Also underinflated tires wear out faster and they waste fuel. So it's costly to not stay on top of proper inflation.

What's the practical value of the TPMS system? Well, it's twofold. First, it can alert you when your tire is losing pressure due to a puncture or a bent rim. That's an important warning that you might not have gotten until next time you gassed up.

The second is that we all occasionally forget to check our tire pressure. So it's a fail-safe system to let you know there's a problem brewing.

Other things can cause your TPMS system to go off. The system also monitors itself. The sensors that are mounted in the wheels have little batteries that send a signal to the monitor. The batteries go dead over time and the TPMS system will let you know. And the sensors could break. Also road salt from our MN roads can ruin them.

There's also a hassle factor that your Cold Spring, MN, tire center has to contend with. For example, when you have your tires rotated in Cold Spring, the TPMS system has to be re-calibrated so that it knows which tire is on which corner of the car. Same is true for when you have new tires or winter tires installed. Flat repairs, as well.

That takes extra time. And it requires the right equipment and training. Special – and expensive – tire change machines need to be used with some sensors. It's all complicated by the fact that there are a number of different TPMS systems in use so the tire professionals at Bauer Auto Service need equipment and training for each kind. Tire centers have had to raise the price of some of these basic services to offset their increased costs.

Also if you add custom wheels on your vehicle, you need to put in new TPMS sensors if your originals won't work on the new rims. If you don't your TPMS light will be on constantly and you won't have the benefit of the warning system.

All in all, the mandated TPMS systems will save lives, so they're worth the added hassle and expense.

Timing Belt Service to Save Big Bucks in Cold Spring

Your engine is like a finely choreographed dance. All the parts have to work together. If the timing is off at the ballet, dancers crash into each other and fall down. It the timing is off in your engine, it may not run at all. One of the most intricate dances in your engine has to do with the combustion cycle.

Your vehicle engine has cylinders in which a piston travels up and down. At the top of the cylinders are valves that open to bring in the air and fuel. And there are valves that open to let out the exhaust after the fuel has been burned.

Call Bauer Auto Service at 320-685-8846 for answers about your timing belt, or drop by our Cold Spring, MN, service center on 14455 State Hwy 23.

It's critical that the values be timed to open and close at precisely the right time in the combustion cycle, or the engine will run poorly or not at all.

The timing belt is responsible for rotating the shafts that control the valves. It's vital and precision work. Timing belts are made of very tough, flexible material. They can last a long time. But they eventually wear out and can break. The consequences can be disastrous.

In some engines, the valves actually protrude far enough into the cylinders that they could come in contact with the piston. If the timing belt breaks, the pistons will smash into the valves. Valves get bent or broken. If the engine is spinning fast enough, the broken parts will shred the cylinder head as well. Repairing this damage can cost several thousand dollars.

It's a sad day when this happens; especially since it usually can be avoided. Manufacturers have issued recommendations for when you should replace your timing belt. For some engines, it's at 60,000 miles/97,000 km. For others it's at 90,000 miles/145,000 km or more. If you're approaching 60,000 miles/97,000 km or have passed it, make sure you check your owner's manual or with your Cold Spring auto service advisor at Bauer Auto Service for when the timing belt should be replaced. Don't let this one slip by.

Now some timing belts are visible and can be inspected. Others are hidden under a protective cover and are hard to get to. Some timing belts also drive the water pump. If you have a leaky water pump, the coolant will contaminate the timing belt and could make it fail sooner. So if you have this kind of engine, get it in to Bauer Auto Service for an inspection right away if you have a coolant leak.

Most people in the Cold Spring area with this engine design end up with a new timing belt when they replace the water pump. And when you're having your timing belt replaced on schedule, check with your Bauer Auto Service auto service advisor to see if it makes sense to install a new water pump, even if it isn't currently having problems, since most of the labor is already being done any way for the timing belt replacement.

As a heads up; larger engines will often have metal timing chains rather than belts. The chains don't need to be replaced like belts.

We've already told you how very expensive it can be to get your car running again after a timing belt fails. You also need to know that replacing the timing belt is very labor intensive and is one of the most costly maintenance services you will have. So if you will be at the point where your timing belt should be replaced in the next year or so, ask for an estimate from Bauer Auto Service in Cold Spring, MN, so you can begin to prepare for the expense.

We at Bauer Auto Service, your Cold Spring service center, can be a valuable partner. Please take advantage of our knowledge and experience.

Using Proper Fluids in Your vehicle

Today, Bauer Auto Service is writing about the proper fluids for your vehicle. It's become more complicated with changes in automotive design and manufacturing. It's not that people in Cold Spring are confused as much as they don't realize how much things have changed in recent years.

If you have questions about the fluids in your vehicle, please don't hesitate to stop by Bauer Auto Service. You can find us on 14455 State Hwy 23 in Cold Spring, MN 56320.
Just give us a call at 320-685-8846.

Let's take engine oil. Twenty or 30 years ago, there were just a handful of different weights of oil. The weight of an oil is a scientific measure of its properties, particularly its viscosity or thickness.

It was common in those days to use a lighter weight oil in the winter when it's cold outside. That way the oil would be able to splash around inside the engine and protect the parts before it was fully warmed up. And a heavier weight oil would be used in the summer. The thicker oil wouldn't thin out too much in the summer heat and vaporize in the engine.

Modern valve trains have become very complicated with more moving parts and small passages than ever before. The valve train is in the top of the engine, so when the vehicle has been turned off for a while, the oil tends to run down to lower areas.  That means the valve train parts are vulnerable at start-up, before the oil starts circulating.

So new weights of oil have been introduced to meet the engineering specifications of these newer engines.

Manufacturers are recommending specific weights of oil. The recommendation is often printed on the oil fill cap. It's certainly in the owner's manual. Of course, Bauer Auto Service in Cold Spring can look it up for you.

It's more important than ever to have the correct weight of oil. The wrong weight could actually harm the engine.

Other fluids are also becoming more sophisticated. In the last few years new types of transmission, power brake fluid and coolant have all been introduced for some of the same reasons as for engine oil.

In addition, vehicle manufacturers are now using a wider variety of materials in these systems. Looking at the cooling system as an example, it used to be that the parts were all made out of steel or iron and the hoses were rubber. Now, some parts are plastic, aluminum or other materials.

So the anti-corrosion additives contained in the coolant, or anti-freeze, need to be different in order to protect the different materials used to make the cooling system. If you use the wrong coolant that wasn't formulated to protect your plastic cooling system parts, they could become corroded and fail. And if you're using the wrong coolant, your cooling system won't be covered under warranty. So it's important to use the right coolant and to not mix different types.

Your owner's manual or service advisor at Bauer Auto Service can make sure you're using the right type. You may have heard of universal coolant. Universal, or global, coolant can be added to other types without harmful reactions. That's OK for an emergency top off, but following your manufacturer's recommendation for your vehicle or other auto type is always a safe bet.

In the area of brake fluid, there are a couple of new formulations. It's important to remember that the new ones aren't better than the old ones. They're just different formulations for different vehicles. So if your vehicle calls for DOT 3, using DOT 4 or DOT 5 is not an upgrade. Use the recommended formula.

There are fluid formulations for vehicles with higher mileage. These are special engine oil, transmission fluid and so on that contain additives to condition and restore seals and gaskets in older engines.

They're fine to use as long as they're a variant of the proper fluid. In other words you can use a high mileage engine oil as long as it's also the correct weight recommended by the manufacturer. Same goes for transmission fluid; as long as it's the right type for your transmission.

Fall and Spring Checkup in Cold Spring

When I was a kid, my dad always made sure he took the cars in for Spring and Fall checkups. I was telling a friend that it's about time to get into Bauer Auto Service for a checkup and he said that he read on the internet that modern cars don't need seasonal service.

My friend is (technically) right about some things, but from a practical standpoint, a seasonal check up still makes sense.

Back when my dad was teaching me about how to take care of the family vehicle, most of them used a different weight of oil in the winter and in the summer. But most of today's modern engines run the same oil year round. High-tech engines and high-tech motor oils are better able to handle the seasonal changes.

Your owner's manual or Cold Spring service advisor at Bauer Auto Service can tell you the right oil to use.

Of course, you're concerned about the coolant or antifreeze. You don't want to overheat in the MN summer or freeze up in the winter. Your engine cooling system protects against both of these things. And modern coolant — 'antifreeze' as it's sometimes called — is up to doing both very well. It's designed to last for longer distances than most people drive in a year or two.

So how does a Spring and Fall check-up fit in? Let's start with Spring. Summer is coming. That means heat, more driving and road trips. It just makes sense to check your fluid levels and do a visual inspection to see that everything is up to snuff.

You may not be scheduled to drain and replace the coolant for some time, but you need to make sure you have enough coolant and that you don't have any leaks or hoses that are about to fail.

That's pretty practical: a check-up to see if there are any problems or emerging conditions that could later become a problem, like a cracked belt.

And the same principle applies for getting ready for winter. Cold weather means lots of failed batteries. It takes more power to crank up a cold engine, and cold also decreases the available cranking power the battery has available.

So a battery test in the Fall could tell you if you've got a battery that is running on its last legs. And of course, if you live where winter temperatures get below 45 degrees F (7 degrees C) or you have ice and snow, you'll want to consider changing to winter tires.

So Spring and Fall auto checkups at Bauer Auto Service are practical reminders to get ready for the demands of the hot and cold seasons to come.

And odds are that you have one or more routine services that are due anyway. Like a transmission service, brake or power steering fluid, differential service — stuff like that. Are your wiper blades still good? Are your headlamps starting to dim?

So Spring and Fall, change your clocks, replace the batteries in your smoke detectors and get a check-up for your cars.

See, dad was right again.

Come and see us at Bauer Auto Service for your Spring and Fall automotive checkup.
