    Whether we’re talking about your engine, transmission, differential, suspension, or otherwise, correct specifications are necessary to keep your car, truck, or SUV reliable, drivable, and running smoothly. From our team here at Ponci's Diesel Center in Fortuna, CA, here’s what you need to know.

  • Let's Get to The Basics of Your Transmission

    The hydraulic system in your transmission is responsible for telling the mechanical components what to do, and when to do it. In order to better understand how your transmission works, it’s important to understand the mechanical components of it.

  • Maintaining the Cooling System in Your Vehicle

    Your vehicle's cooling system is one of the most important systems in your vehicle. Inside your engine, spark plugs ignite the fuel within the cylinders to produce small explosions that propel your vehicle down the road. With small explosions comes scorching temperatures that can destroy your engine if not controlled. There are two types of cooling systems - liquid-cooled and air-cooled. 

  • Maintaining Your Coolant System Year Round

Preventative maintenance and repair when a problem occurs are your two concerns, and both will keep your car on the road far longer if observed properly.

  • Properly Maintaining Your Battery

    Your car’s radio and headlights, plus a slew of other important functions, are powered by an electrical current generated by your vehicle’s engine. A vital part of generating electricity is having a place to store it while it’s not being used. This is where your car battery comes into play. The battery of your vehicle holds electrical energy while the car is off in order to help the engine turn over and create a spark to start internal combustion. Without a working battery, your car will not be able to start. If you allow our team here at Ponci's Diesel Center to perform proper maintenance, an average car battery can start your car reliably for roughly four years.
