Keeping your diesel fleet trucks on the road longer.

Keeping your fuel system maintained will prevent premature parts failure and poor running conditions. Here at AV Automotive Inc we have tips on the important aspects of diesel fuel system maintenance, to keep your diesel fleet trucks running smoothly - longer.

Air. Air in the system causes all kinds of issues, from hard starting, poor running conditions, or an engine that won’t run at all. If too much air gets in the system, the fuel pump won’t be able to deliver fuel, and the engine will stall, die, or fail to start.  Air enters the system via a leak or a bad seal - a deteriorated o-ring, worn component, faulty hose, or otherwise. Here we inspect your lines and connections to ensure they are in good shape and track down any leaks we notice air in the system.

Dirt. Dirt in the system is a pretty obvious issue - it’ll clog the filters, and if for some reason it makes it further down the line, it’ll block injectors or cause them to stick as well. It doesn’t take much dirt in the wrong place to cause a lot of trouble; our diesel technicians make sure your filtration system is in good shape, and only use quality high-quality filters and components.  If we see excessive issues with your filter, then we do additional inspections to make sure you don't have any dirt in your system.  You can't be too careful and while we do offer the best diesel replacement engines by JASPER Engines, we want to be sure your current diesel engine last you a long, long long time!

Water. Water is damaging, and it only takes a little of it to tear something up or make your engine run poorly. Water traps must be emptied, and filters cleared if any water enters the system at all. Essentially, the goal is for fuel to flow with no interruptions from the tank to the cylinder. Anything that disrupts that process will cause a problem. Fuel system flushing is a good way to ensure everything stays clean and in good shape - when performed by our professional technician, saves you a great deal of trouble in the long run.

No matter your repair or diesel fleet truck maintenance needs, we’ve got you covered here at AV Automotive Inc in Upland where we take care of your fleet trucks as if they belong to us. The goal is to keep your trucks on the road and the repair bills down with top diesel maintenance vs expensive and unscheduled repairs.  Talk to our diesel technicians about the best maintenance plan based on your diesel truck driving habits.
