Why is Spark Plug Replacement Important?

Why is Spark Plug Replacement Important?

If you’re a client at Good’s Auto Service and your vehicle has over 80,000 miles, you’ve probably heard us talk about spark plug replacement. But what exactly are spark plugs, and why are they important? To understand the importance of spark plug replacement, you first need to know what a spark plug actually does. Let’s discuss. Spark plugs are a vital component in the starting and running of your engine. They are typically located on the top of the cylinder head, and create the spark needed to ignite the air/fuel mixture in each cylinder. When this “explosion” happens, it pushes down on the pistons, giving your engine the power it needs to run. This is a continuous process while you drive down the road. In fact, at highway speeds, one single spark plug creates around 600 sparks per minute! Because of this continuous combustion, your spark plugs are subjected to a great amount of heat and pressure. Which leads us to why we recommend replacing your s ... read more

Do I Really Need to Change My Coolant?

Do I Really Need to Change My Coolant?

The short answer to this question – absolutely. But why exactly? Let’s break down what coolant (antifreeze) actually does for your vehicle. The main roll of your cooling system is exactly what it sounds like; cooling. It keeps your engine running at the optimal temperature by transferring heat to the radiator. As coolant runs through the engine, it absorbs heat. Once it makes its way to the radiator, it is quickly cooled by airflow from driving and/or radiator fans. Once cooled, it flows back to the engine to start the process over again. Now that’s all fine and dandy, but what about winter months? Being in Lititz, PA, you know our seasons range from sweltering hot to freezing cold. Well, coolant also plays a vital role during those bitter cold months. Because of the ethylene glycol found in coolant, it lowers the freezing point of the engine. This ensures the engine won’t freeze up while sitting out in the freezing cold. Your cooling system is able to effec ... read more

Don't Ignore the Tire Pressure Light

Don't Ignore the Tire Pressure Light

Most vehicles these days are equipped with a Tire Pressure Monitoring System (TPMS), which alerts the driver that one or more of the tires are getting low on air. A yellow light will appear on the dash when the TPMS recognizes the loss of tire pressure. Here at Good’s Auto Service, we HIGHLY recommend that this light not be ignored. Either stop at a gas station that has an air service station, or bring it by the shop to have your tires aired up. Driving around with flat tires is not only hard on your vehicle, it can also turn into a safety hazard if left unchecked. If you check out the pictures attached to this post, it’s pretty easy to see why ignoring that little yellow light is a big no-no.
