Automotive Dashboard Warning Lights


Today’s vehicles are filled with electronics and sensors to keep track of how your vehicle is functioning and make driving easier. Every warning light on your dashboard should light up for a few seconds when you first start your engine. 

It is important to know what your vehicle’s warning lights mean because they can give you important information or be indicative of serious problems developing even if you don’t notice anything wrong, which lets you take care of them before they become more expensive and destructive problems.

When something is wrong with one of your vehicle’s many systems, usually a warning light on the dashboard will illuminate. However, it can be hard to figure out what the lit up pictogram on your dashboard is trying to tell you.

Catalytic Converter Replacement

Every street legal vehicle manufactured in the past several decades has at least one catalytic converter mounted within its exhaust system. Many luxury cars have two, or even more. The purpose of the catalytic converter is to superheat unburned particles in your engine’s exhaust gases. As your engine warms up, the catalytic converter will heat to an operating temperature of 500 - 1200°F. This allows it to burn harmful particles in the exhaust gases, converting them to water vapor and carbon dioxide. 

The catalyst inside is usually made of precious metals such as platinum, rhodium, or palladium, which means that catalytic converters usually cost several hundred dollars. Thieves sometimes target catalytic converters because of this, jacking cars up and cutting them out with hacksaws. When your vehicle’s catalytic converter is no longer able to burn off the unburned hydrocarbons in the exhaust, your exhaust gases may begin to smell abnormal, your engine may run rough or misfire, and your check engine light will most likely come on.

Spark Plugs and What They Do

Spark plug - the name itself is pretty self explanatory. To put it simply, your vehicle’s spark plugs are parts that plug into the top of your engine’s cylinders and create a spark which ignites the air and fuel mixture inside to start the engine and keep it generating power. The number of spark plugs in your car’s engine is usually the same as the number of cylinders, although some automakers will use two spark plugs per cylinder. 

Like any other part of your vehicle, your spark plugs will wear out over time and need to be replaced. Worn spark plugs make it harder for the air-fuel mixture to ignite, causing your engine to misfire. Your car may still start and run, but it will run very poorly. Spark plugs are relatively easy to replace in some vehicles, but may be labor intensive and require removal of the intake plenum in others.

When you get your spark plugs replaced, it is a good idea to inspect your ignition cables as well. There are different ratings for spark plugs, and the correct rating for your vehicle should always be u

Fuel Pump Repair


You probably know that your vehicle has a gas tank which is usually several feet away from its engine. You may have also heard that the Ford Model T had a gravity-fed fuel system, which would result in owners having to drive backwards up hills to prevent the engine from becoming starved of fuel and stalling out. Of course, today’s cars are much more advanced - they use a component known as the fuel pump to keep gasoline flowing into your engine. If your car stalls out nowadays and there aren’t any mechanical problems with it, you’re probably just out of gas, no matter how steep of a hill you’re driving up.

Your engine needs gas to run. A failing fuel pump will not be able to pump the gas as well from the gas tank into the engine, and will become less and less efficient as it wears out more. Eventually, it will be so inefficient that it will be unable to pump an adequate amount of gas to your engine, and your car will no longer be able to start or run.

Rack and Pinion Steering Repair


Most vehicles have a steering system that consists of a rack and pinion. The rack and pinion is the part that converts the rotational movement of your steering wheel into the left and right motion of your car’s front wheels. It works by a pinion gear on the end of the steering shaft, which moves along teeth on a horizontal rack. Rack and pinion systems have a simple design, and are usually not too hard to repair if any issues arise.
