Common DEF System Problems
Common DEF system problems include contamination, poor storage, mixing with diesel, sensor failures, low quality, incorrect DEF levels, freezing, and pump or injector issues, which can damage the SCR system or shut down the engine. Maintaining proper DEF quality and levels is crucial for emission compliance and avoiding warning lights or limp mode. DEF is…

The Key Differences Between Diesel Fuel: Diesel 1 vs Diesel 2 Fuel
The main difference between Diesel #1 and Diesel #2 fuel is that Diesel #2, ideal for heavy-duty trucks, is denser in energy, more commonly available, and generally more cost-effective for warmer climates, while Diesel #1 is more refined, thinner, and better suited for cold weather and easier engine starts due to its lower gel point.…

DEF in Cold Weather: Temperature of DEF Freezing Point
Diesel Exhaust Fluid (DEF) freezes at 12°F (-11°C) because of its 32.5% urea content. When frozen, DEF expands by about 7%, which can crack or damage tanks if overfilled. Although freezing does not degrade DEF quality, maintaining proper storage temperature and using heated DEF systems are essential to prevent tank damage, operational issues, and increased…

What Happens to Diesel Fuel in Cold Weather?
In cold weather, diesel fuel thickens and gels, potentially clogging fuel filters and causing engine issues, as the paraffin wax it contains solidifies into crystals. These issues can result in reduced fuel flow, engine damage, and in extremely low temperatures, the cloud point can be triggered, where wax crystals form, causing fuel cloudiness. What Happens…

How to Winterize a Generator
To winterize a generator, prepare it for storage by stabilizing the fuel, changing the oil, cleaning the air filter, and optionally disconnecting the battery to prevent drain, and consider using cold flow improvers, engine block heaters, battery warmers, snow hood kits, and louvers/dampers. Running the generator for 10-15 minutes before use warms the fuel and…

How To Prevent Diesel Fuel Gelling?
The Chilly Truth About Gelled Diesel Maybe you know the scenario. Coming off an extra cold night, you find that starting your diesel engine in your vehicle or equipment for the day’s work yields only repetitive cranking coupled with an inability to fire up and turn over. You might discover that: · The engine starts…
