It’s important for safe driving that two of the most important systems in your vehicle work right. One is the brakes. The other is the steering. Nearly all vehicles on the road have some sort of power steering that allows you to direct a very heavy machine with little effort. There are two types, hydraulic and electric. Many newer vehicles have electric power steering that uses an electric motor to make your steering easier. But there are many vehicles on the road that use a system that has been around for years. It uses a power steering pump, a cylinder, several valves, and hydraulic fluid to make it easy for you to turn the wheel. If you have hydraulic power steering in your vehicle, it’s important to change your power steering fluid every once in a while. Over time, the fluid gets contaminated with dirt and other particles. You might notice your steering is loose, maybe harder to turn and makes a low, strainin ... read more

Who thinks about their fuel gauge? You probably don't… until it doesn't work any more. Then you have to guess how much fuel is in your tank, and that's no way to live life on the road. Fuel gauges, like every other part in your vehicle, can fail. And when yours stops working, you will probably want to head over to your service facility soon, because no one relishes running out of fuel. The fuel gauge system is much more than just the gauge you can see on your instrument panel. Most systems have a float inside the fuel tank that goes up and down depending on the fuel level. It's called the fuel sending unit, and it sends an electrical signal to the gauge (on the dash) telling it to display how much fuel is left in the tank. So, what could go wrong? Well, a few things. For one thing, corrosion from bad fuel can cause it to stick and it won't move up and down any more. So you could fill up your tank and the gauge would still rea ... read more

There's a belt that snakes through your engine. It's even named for a snake, the serpentine belt. It'll bite you when it breaks, possibly leaving you stranded. So, it's good to know a little about this snake-like belt. In early engines, there were lots of belts. They were used to convert the rotating power of the engine to turn a mechanical part. But engineers had an idea. Why not consolidate all those belts into one that ran a bunch of different parts simultaneously? Voila! The serpentine belt. It's found in the front or side of your engine unlike older belts which were often in a V shape, the serpentine belt has ribs on it which more effectively connect with the pulleys that power the other components. A serpentine belt may power the water pump, power steering pump, alternator, and the air conditioning: all from one crankshaft. Now, all that's fine when everything is working well and the belt is intact. But when a serpentine belt ... read more

Steering a vehicle these days doesn't take much effort, but if you got behind the wheel back before power steering was invented, you'd need to practically have the strength of Hercules to turn the wheel. The first power steering systems widely available changed everything. Chrysler introduced its Hydraguide power system in 1951. The "hydra" was for a hydraulic pump. It pressurized fluid that multiplied the force applied to the steering wheel so it was easier to turn the wheels on the ground. That pump got power from a belt attached to the engine, but unfortunately it wasted a lot of energy in the process. Plus, the system of hoses and pumps required a fair amount of maintenance and repair. Some say this system provides the most "natural" steering experience of power systems. Recently, automakers have turned to electric power steering. It gets its power from the car's electrical battery and charging system and uses an electric motor to turn the wheels. Sin ... read more

If that little brake warning light pops up on your dash, do you know what it means? Well, if you said no, you wouldn't be alone. You know it has something to do with your brakes, but exactly what? You're not sure. One of the reasons is that it could mean a lot of different things. It could be something simple, like you put your parking brake on and forgot to take it off. Easy fix, you're on the road in seconds. Or, it could mean there's something wrong with your anti-lock brake system. That is a pretty complex symphony of speed sensors, computers and wiring, and sometimes things get a little out of whack. You could have a defective sensor or some wiring may have gotten damaged or come loose. A trained technician at Mackert Automotive LLC with special equipment can sort it all out. It's also possible you have low brake fluid. That could be caused by a number of things. One simple reason is that your brake pads have worn down. Replacing them could solve the problem. Another possibility i ... read more
