Diesel engines are known for their durability, fuel efficiency, and torque. However, unlike gasoline engines that rely on spark plugs for ignition, diesel engines use a different process. One critical component for starting a diesel engine, especially in cold weather, is the   glow plug . This article explores   how glow plugs work in diesel engines , their purpose, and how long they typically last. What Are Glow Plugs? A  glow plug  is a heating device used to assist in starting diesel engines. It is located in each cylinder of the engine and heats the air inside the combustion chamber. This heat helps ignite the diesel fuel when the engine is cold. Unlike gasoline engines that use a spark to ignite the fuel-air mixture, diesel engines rely on heat generated by compression. When temperatures drop, the air alone isn’t hot enough for ignition, and that’s where glow plugs come in. How Glow Plugs Work Glow plugs operate by heating up an electrical coil inside them. When...

Diagnosing electrical issues in vehicles can be time-consuming and frustrating without the right tools. A Power Probe kit simplifies this process, offering precision, efficiency, and versatility. Whether you're a professional technician or a DIY enthusiast, having a complete diagnostic toolset like the Power Probe Master Combo Kit can transform how you work on vehicles. What Is a Power Probe Kit? A Power Probe kit is a comprehensive electrical diagnostic tool used to test circuits, check voltage, identify faulty wires, and activate components—all with a single tool. Designed with user convenience in mind, it streamlines troubleshooting tasks that would otherwise require multiple tools and considerable time. Types of Power Probe Kits and Tools Before diving into the benefits, it's helpful to understand the different options available: Power Probe 3 Parts: This tool includes a voltage and polarity tester, continuity tester, signal injector, and ground tester all in one. Power Pr...

The fuel rail pressure sensor measures the fuel pressure inside the fuel rail and communicates with the ECM to optimize fuel injection timing and quantity. This ensures efficient combustion and peak engine performance. If the sensor fails, it can send inaccurate data, resulting in poor throttle response, black smoke, or triggering a check engine light. Where is the Fuel Rail Pressure Sensor Located on the 6.6 Duramax? The location of the  fuel rail pressure sensor  on the 6.6 Duramax engine depends on the generation: For LLY and LBZ Duramax (2004.5–2007): The sensor is located on the driver's side fuel rail, near the rear of the engine. For LMM, LML, and L5P Duramax (2007.5 and newer): It is typically positioned on the passenger-side fuel rail, beneath the intake manifold or intercooler piping. Access may be slightly restricted due to engine components, so removing the intake tubing or EGR system may be necessary for easier reach. Tools and Materials Needed Before you start th...

The 12 valve Cummins is a legendary diesel engine known for its simplicity, strength, and reliability. Found in Dodge Ram trucks from 1989 to 1998, this engine helped revolutionize the diesel pickup market. Whether you're a truck enthusiast or simply researching diesel performance options, understanding the 12 valve Cummins specs and how it compares to the 24 valve Cummins is key to making informed decisions. Let’s dive into what makes this engine so iconic and how it holds up against newer technologies. A Brief History of the 12 Valve Cummins Cummins introduced the 5.9L 12 valve turbo diesel engine in 1989 in the Dodge Ram 2500 and 3500 trucks. Prior to its release, most diesel pickups were slow and underpowered. The 12 valve Cummins changed the game by offering excellent torque, towing capacity, and fuel economy in a simple mechanical package. This engine was produced until 1998, when it was replaced by the 24 valve Cummins version. While both engines are part of the Cummins B-se...

What Is the 7.3 Diesel Turbo? The 7.3L Powerstroke diesel turbo is a reliable workhorse engine built by Navistar International and used in Ford trucks from 1994 to 2003. Its turbocharging system, especially in models from 1999.5 to 2003, uses a Garrett GTP38 turbocharger. This system boosts horsepower and torque, improves towing capacity, and increases fuel efficiency. The 7.3 Powerstroke turbo comes in different forms—stock and upgraded versions. For example, the 2000 7.3 turbo typically includes a stock GTP38 turbo. Many truck enthusiasts opt for performance upgrades like the GTP38R turbo 7.3 Powerstroke or a ball-bearing upgraded turbo for 7.3 Powerstroke models. Although this turbo setup is known for durability, several common issues can impact performance. Let’s explore the top 5 problems and how to fix them. 1. Turbocharger Boost Leaks The Issue Boost leaks are one of the most common problems with the 7.3 Powerstroke stock turbo. These occur when there’s a loss of pressure betwee...
