Obviously, the dirtier your fuel system is, the bigger the improvement you will see in performance and fuel economy after a fuel system cleaning. But it is important not to wait until your system is running poorly. If you do, by the time you get a cleaning, you’ve wasted hundreds of dollars in gas or even possibly damaged your fuel injectors and catalytic converter.

When something goes wrong with your vehicle, it can be tempting to take the cheapest route. With eBay, Amazon, and the countless other sources for car and truck parts on the market today, many people decide to go that route to save some money. Here we choose only quality automotive parts for our Fortuna, CA driver at Ponci's Diesel Center because we want to ensure their parts match our commitment to providing them high quality repairs.

Your drive belts are simple but integral components to the function of your car, truck, or SUV. At Ponci's Diesel Center in Fortuna, CA, belts are one of the first things we assess when looking over a vehicle, as they alone are in charge of operating your AC, water pump, alternator, and power steering.

At Ponci's Diesel Center in Fortuna, we understand that safety and driving comfort are largely dependent on truck maintenance. Driving in the rain can be a hassle, especially if your vehicle isn’t prepared.
Essentially, there are a few things you can do to ease the burden of driving in the rain. Keep good quality windshield wipers installed, maintain a clean windshield, and regularly coat your windshield with Rain-X or comparable water-resistant chemicals. If applied properly, water-resistant coatings will dramatically increase visibility on rainy days. Quality windshield wipers, in good condition, are equally effective.
If your wipers don’t completely wipe away water with each pass, get them replaced. Driving in the rain is hard enough; inadequate equipment to deal with the situation only makes it that much more difficult. A clean windshield also goes a long way...rain won’t wash off the dirt that has had adequate time to adhere to your glass.
If you need new wipers, bring your truck to Ponci's Diesel Center and let one of our experienced technicians get you fixed up. No matter your repair or maintenance needs, our team has you covered.

When you are having trouble with your car or truck starting and you open the hood up to take a peek to see this....you'll see what an overly corroded battery looks like. This happens naturally over time on vehicle battery terminals. If you are like 99% of normal Fortuna drivers, you don't check your oil or your battery so you don't keep an eye on the amount of corrosion that's building up on your car or truck battery. Here at Ponci's Diesel Center, we do and there are solvents that we can use here in the shop during a battery maintenance service that will help slow the corrosion process but nothing that can prevent it 100%. Way before it gets to this point, we will be suggesting you consider replacing the battery.

Your transmission suddenly isn’t shifting right. So what’s wrong with it? Do you need your transmission rebuilt? Good question. Unfortunately, the answer is: No one knows. At least, not yet. To find out what’s causing your transmission problem, a technician is going to have to perform a series of tests. Basically, these tests are designed to answer the simple question: “Is it inside or outside?” That is, is the problem inside the transmission, or in one of the many control systems that operate the transmission?

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.

As cars become more technologically advanced, the importance of your vehicle’s battery becomes more important. In the old days, a car battery essentially worked, or it didn’t; if it was good enough to start the car, it was good enough. Modern vehicles are a different story. A faulty battery can cause a variety of issues, including engine codes, sensor failures, irregular transmission behavior, and the list goes on.
Battery failure often causes issues that are commonly misdiagnosed, and in the hands of the wrong auto repair shop, a mechanic may spend hundreds of your hard-earned dollars chasing problems that don’t exist. At Ponci's Diesel Center in Fortuna, CA, our mechanics are familiar with modern vehicles and the problems that accompany them.
