The automotive air conditioning (A/C) system is a crucial component for ensuring comfort during hot summer months. An essential component of the A/C system is the refrigerant, which removes heat from the cabin and circulates cool air. Over the years, different types of refrigerants have been used in automobiles, and it's important to understand the most common types and their benefits. R-12 (Freon) - This was the original refrigerant used in automotive A/C systems, and was very popular until the 1990s. R-12 has a high global warming potential, which is why it was banned and replaced by newer, more environmentally-friendly refrigerants. R-134a - This refrigerant became popular in the 1990s and is still widely used in vehicles manufactured after 1996. R-134a is an HFC (hydrofluorocarbon) refrigerant that has a low global warming potential and is safe for the environment. R-1234yf - This is the latest and most advanced refrigerant used in modern vehicles. R-1234yf has a very low gl ... read more

On average, a car battery should last approximately 3 to 5 years. Beyond this time window, batteries should be monitored more closely as they become more unreliable and prone to dying. In fewer cases, some vehicle owners may have to replace their vehicle’s battery sooner than 3 years. Considering your battery is where all of the electrical power is stored in your car, you should know how to spot the signs of a dead battery. 5 Ways to Tell If You Need a Car Battery Replacement Half-functioning Accessories - A good method to check your battery is to check how your accessories run right after your car starts up. For example, see if your headlights are dim. Rev your engine to see if the lights react differently. If so, it may mean that your battery is weak and cannot meet power demands. Battery Corrosion - When was the last time you inspected your car battery? If you open your hood only to see a blue or green substance covering your battery terminals, there is a good chance that y ... read more

Transmission fluid is what helps to keep your car moving while in gear. The gears in your transmission are constantly meshing, which produces a lot of heat. Over time, the transmission fluid can break down and become less effective at doing its job. That's why it's essential to change your transmission fluid regularly. But how often should you do it? How Often Should You Change Your Transmission Fluid? The general rule of thumb is to change your transmission fluid every 30,000 miles or every two years, whichever comes first. However, this may vary depending on the make and model of your car as well as your driving habits. If you do a lot of stop-and-go driving or frequently tow heavy loads, you may need to change your transmission fluid more often. Some carmakers have started to extend the recommended interval for changing transmission fluid. For example, Honda now recommends that you change your transmission fluid every 100,000 miles under "normal" driving conditi ... read more

Transmission speed sensors are used to calculate the actual gear ratio of the transmission while in use. There are generally two speed sensors that work in conjunction to provide accurate transmission data to the vehicle's powertrain control module. The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission's input shaft. The other sensor is the output shaft speed (OSS) sensor. If either of these two sensors falls out of alignment or experience electrical issues, it impacts the operation of the entire transmission. After registering data, the two transmission speed sensors, also commonly referred to as vehicle speed sensors (VSS), send data to the powertrain control module (PCM), which compares these two inputs and calculates which gear the transmission should engage for efficient driving. The actual gear ratio is then compared to the desired gear ratio. If the desired gear and the actual gear do not mat ... read more
