At Autotronics of St. Peter we hear from a lot of people who are excited about the new diesel engines that will soon be available in passenger cars and SUV’s. But our MN friends are often curious about the preventive maintenance requirements. People may not know that diesel engines have long been used extensively in Europe and Asia. In fact, in some markets, there’re nearly as many diesel powered passenger cars as there are gasoline.

Here’s who’s announced or is expected to announce new diesels for North America: BMW, Mercedes, Audi, Volkswagen, Nissan, Honda, Toyota, Hyundai and Subaru. Of course, the US auto makers will be expanding their diesel offerings as well. Diesels will become a very big deal here in MN.

You may ask, why has it taken so long getting to MN and North America? There are a bunch of reasons like fuel tax policies and such, but the biggest hurtle was that MN diesel fuel had a high sulfur content – too high for the latest generation of highly refined diesel engines. Recent government mandates to remove sulfur now opens up MN to the engines the rest of the world’s been enjoying for a long time.

Why are diesels so popular worldwide? Well, for starters, diesels get up to 30% better fuel economy than gas engines. And they last a lot longer. And modern diesel engines are refined, quiet and powerful – and there’s none of that black smoke we used to see.

Some people may think that diesels create more pollution. But, you need to rethink diesels. Environmental pollution standards for diesel cars and light trucks are scheduled to be as strict as they are for gasoline vehicles. A modern diesel engine is as clean as a gas engine.

Repair costs are similar to vehicles with gas engines. As with gasoline engines, proper maintenance is the key to long engine life and to avoiding repairs. So pretty much what we have come to expect with gas vehicles; coolant system service, transmission service, power brakes, power steering, differential, filters, fuel system and so on. And the payoff for you, if you’re the kind that likes to keep your vehicles for a long time, is that a properly maintained diesel engine can last for many, many years.

If you’ve ever walked into your garage and noticed it smelled like gasoline, pay attention. Gasoline can be dangerous, both from the health problems fumes can cause and the fire danger gasoline presents. 

There are many things that can cause a vehicle to give off a gasoline odor.  One of the easiest to track down is the gas cap.  It could be missing or it doesn’t seal well any more (they do wear out).  That can also cause the Check Engine light to light up, so those are clues to tell your service advisor when you take it in for diagnosis.

Another thing that can cause the Check Engine light to come on and produce a gasoline smell is the fuel filler neck. It’s the part that goes from the place you put your fuel in to the gas tank. Over time, these can wear out and fail (they’re made out of rubber or metal).  They can leak gasoline, too.

It’s always a good idea to check the garage floor for any gasoline puddles.  Note the location of the puddle in relation to the vehicle. If it’s near the back, that’s possibly the fuel filler neck or the gas tank leaking.  In the middle of the vehicle? May be fuel lines.  Near the front? Could be fuel injectors (or carburetor if you have one) or fuel pump. 

There are other causes of gas odors, and you need an expert to figure out the source soon.  Gasoline leaks are nothing to play around with.  Gasoline is flammable, potentially explosive and its fumes can damage your lungs. A trained technician can pinpoint the cause and get your garage back to smelling like a normal garage again.

We usually take our vehicle’s easy steering for granted until something goes wrong.  Power steering is what makes it almost effortless to turn the steering wheel, aiming your vehicle in the direction you want to go. Without the assistance of power from the engine, steering would be a laborious process, so you want to make sure the system is working well.

Power steering systems are usually one of two types, hydraulic and electric.  The hydraulic type uses a pump that is driven by either a belt or an electric motor.  This system uses hydraulic fluid to create pressure that gives your steering the power assist.  Since that pump is always working, time and distance traveled eventually take their toll, and these systems need to be periodically inspected.  Also, while that hydraulic fluid can last for years, it should be replaced periodically as it degrades over time. Your vehicle’s owner’s manual contains the manufacturer’s recommendations.

A technician can check for leaks in the hoses, pump housing or reservoir.  Also, the belts should be inspected and so should the pump, as these can fail.  Signs of a failing pump are a groaning noise when you turn the steering wheel, stiff steering, squealing noises when you first start your car and puddles of a reddish-brown fluid under your vehicle. 

The other type is called EPS, or electric power steering, which is becoming more commonly used in the latest vehicles.  It only delivers power assist when you need it and has an electric motor that supplies that steering help.  It’s more efficient, accurate, compact and clean. And because it has a lot fewer components, it’s easier to maintain. 

If you have electric power steering, you may notice sometimes it’s hard to turn the wheel or your Check Engine light comes on.  Sometimes the power assist motor fails or there can be problems with electrical connections.  Any time you have symptoms, it’s important for your safety and that of drivers around you that you have a technician check them out.

Properly working brakes are essential for the safe operation of any vehicle.  Stop! And make sure yours are working properly.
