When it comes to transmissions, your fluid level is essential. Too much or too little fluid can affect pressure, cooling abilities, and lubrication. In order to best care for your vehicle, it's important to know what to look for, so from our shop here at Craig Johnson Automotive here are a few tips. 

Sluggish. Squealing. Unreliable. Vibrating. If any of these descriptors fit your vehicle’s recent behavior, it just might be trying to tell you something – like it’s time for a tune-up.

Today’s vehicles differ significantly from their decades-old brethren that required a tune-up every 10,000 or 20,000 miles. With newer vehicles, it’s increasingly common for manufacturer-recommended service intervals to stretch to 100,000 miles before certain maintenance items, such as replacing the spark plugs, should be completed. 

To some drivers, picking out the right tire is just as important – and just as much fun – as finding the right shoes is to a runner. For many people, they have found that shopping for tires is overwhelming because there are just so many choices. AT Craig Johnson Automotive IN Rowland Heights, CA, our technicians are ready to help you make that decision.

Your vehicle's engine needs clean air to burn the fuel – and it needs a lot of clean air. In fact, a typical vehicle needs about 216,000 gallons of air for every tank of gas. All that air passes through a filter that catches the dust and dirt. Eventually, the filter gets completely full, and because the filter can only hold so much, dirt starts getting through. At Craig Johnson Automotive in Rowland Heights, we ensure you get the best air quality in your vehicle and explain the process of where this dirty air is going to our area drivers. 

Your car’s fuel system works with the rest of the engine control system to deliver the best performance with the lowest emissions. Check your car’s fuel system regularly or immediately if you smell gas or suspect a problem.

What does it do? - The fuel system transfers fuel from the fuel tank and passes it through a fuel filter for straining before it arrives at the injectors. A pressure regulator controls fuel pressure to ensure good engine performance under a variety of speed and load conditions. Fuel injectors, when activated, spray a metered amount of fuel into the engine. Some vehicles use a return line system to return unused fuel back to the tank.

Do you need new brake pads? Most of the time, if you think you do, the answer is yes. While a lot of auto parts stores sell brake pads with lifetime warranties, don’t be misled...brake pads will still wear down.

At Craig Johnson Automotive in Rowland Heights, CA, we understand that the care for your vehicle is in the details. Transmission work, more so than any other type of maintenance or repair, requires a keen eye and specific know-how.

Without a working battery, your car will not be able to start. If you perform proper maintenance, however, an average car battery can start your car reliably for roughly four years. Your vehicle's radio and headlights, plus a slew of other important functions, are powered by an electrical current generated by your vehicle’s engine but a vital part of generating electricity is having a place to store it while it’s not being used, which is where a car battery comes into play. The battery holds electrical energy while a car is off in order to help the engine turn over and create a spark to start internal combustion.  What you don't want is to have a bad battery!!
