The unmistakable rumble of a HEMI engine is part of its appeal—but when that rumble is interrupted by a rhythmic tapping or clicking, it gets your attention fast. For Ram, Dodge, and Jeep owners, that sound is often referred to as HEMI lifter tick, most commonly associated with the 5.7L and 6.4L HEMI. While not …
Frozen diesel can have a profound impact on your truck or vehicle, and preventing this situation is critical to your vehicle’s long-term health. From older vehicles to modern engines, freezing or gelled diesel is always a risk, and it can reduce performance, reliability and fuel efficiency. One excellent way to improve additive efficiency and reduce …
Diesel exhaust fluid (DEF) helps control emissions, allowing your engine to run cleanly and efficiently. If you’re seeing lost power, lower fuel economy or strange shutdowns, DEF system issues may be the cause. Diesel exhaust fluid issues trigger symptoms such as reduced fuel efficiency, power reduction or unexpected shutdowns. Ignoring these signals will lead to a …
Cold weather places added demands on diesel engines—from fuel flow challenges to thicker lubricants and harder starts. Taking a proactive, science‑based approach to winter preparation helps maintain reliability, protect critical components, and reduce the risk of downtime when temperatures drop. Below, we break down practical, proven cold‑weather diesel maintenance considerations—covering fuel, oil, cooling systems, batteries, …
Winter and cold weather can really bring you down. Not only does it get dark earlier and become too cold out to do much, but your vehicle’s fuel economy just gets worse and worse. There are a lot of reasons why your fuel economy suffers in the winter, by some estimates fuel economy goes down …
The robust L5P Duramax engine was developed by General Motors for the 2017 Chevrolet Silverado 2500HD and 3500HD trucks and GMC Sierra 2500HD and 3500HD trucks. The original 2017 Duramax motor has been upgraded and updated to further increase the engine’s reliability. Today, 445 horsepower and 910 lb-ft of torque make the L5P one of …
Diesel engines are built to take a beating, but they’re not invincible. Unlike their gasoline-powered counterparts, diesels operate at much higher compression ratios. That means more heat is generated right from the get-go. Plus, many diesel owners tow heavy loads or run long hauls, turning up the heat. Overheating in a diesel can lead to …
No, you shouldn’t keep your vehicle’s diesel exhaust fluid (DEF) tank full in the winter. Keeping the tank filled to capacity doesn’t leave space for expansion in cold temperatures. Diesel exhaust fluid is essential to reducing engine emissions. The system sprays it directly into the exhaust stream to convert nitrogen oxides (NOx) into nitrogen and …
Idling alone isn’t enough to prevent gelling in extremely cold conditions. In specific temperature ranges, diesel may thicken or “gel,” reducing vehicle efficiency, increasing engine strain and introducing potential for damage. While it’s a common belief that idling your diesel vehicle can prevent gelling, the heat from idling is generally insufficient to keep the fuel …
