fuel gauge

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.

In the diesel world, "blow-by" is a term you're bound to run across at some point if your line of work involves diesel-powered vehicles of any kind. What is blow-by, what causes it, and how concerned should you be? At CP Diesel & Auto in St Cloud, FL, our fleet maintenance and diesel technicians see it on a regular basis. Here we'll take a quick look at blow-by, correcting it, and preventing it.

What is Blow-By? - Diesel blow-by is a term that describes an event of lost compression into the crankcase. Blow-by occurs whenever a burnt or unburnt fuel and air mixture escape from the cylinder and past the piston rings and into the crankcase. In a perfect world, the piston would be sealed tightly in the cylinder, able to move up and down but keeping all the air and fuel and exhaust that enters or exits the cylinder during the combustion process out of the crankcase. As you'll see, this perfect world doesn't exist, but it is important to minimize the amount of blow-by in a diesel engine.

transmissionPeople idle their vehicles for a variety of reasons - to warm it up on cool days and to keep it cool on warm days. But what does idling mean for your transmission? CP Diesel & Auto in St Cloud, FL has the answers.

bad battery

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 St Cloud 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 CP Diesel & Auto, 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.

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 CP Diesel & Auto in St Cloud, FL, our mechanics are familiar with modern vehicles and the problems that accompany them.

Changing the oil in big trucks and commercial vehicles is an expensive, but necessary, part of keeping your vehicles going. You don’t want to wait until it’s too late to change your oil, but changing it too early can be a waste of time and money. Having your oil tested regularly helps us to hone in on exactly how often your oil needs to be changed, to optimize reliability and efficiency.

fleet trucks

It’s easier than ever to keep your fleet running smoothly for thousands of miles. If a vehicle has less than 50,000 miles on it today, chances are it still has 75 percent of its driving life ahead of it. That’s good news if you’re a company managing a fleet of vehicles. It wasn’t that long ago that hitting the 100,000-mile mark on the odometer was a major milestone. Today, vehicles are built to last. With the proper maintenance and attention, there’s no reason you shouldn’t expect to see that 50,000-mile reading on the odometer one day roll right past 200,000 and keep ongoing. Here at CP Diesel & Auto, we're going to give you some tips on how to make that happen!
