Keeping your fuel system maintained will prevent premature parts failure and poor running conditions. Here at Mr Diesel & Auto Repair 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.

Smoke coming out of muffler

Diesel engines are known for their durability, but even the best engine has to be replaced every once in a while. At Mr Diesel & Auto Repair in Cheyenne, WY, we want you to be aware of signs that your engine is about to call it quits.

fleet

Fleet cars, vans, and trucks see a lot of wear and tear. If your engine has already called it a day, then it’s obviously case closed - you need a new engine or a new vehicle. However, there are many times when an engine is about to go down, and you can get it taken care of before it kicks the bucket for good - saving you time and towing in the process.

I honestly can not say enough good things about this shop, the staff and particularly George, the owner. I’m from Georgia and 1600 miles from home. My 2002 Ford Excursion with the 7.3 Powerstroke was hesitating and cutting off when accelerating from a stop. Not good. Not only did George work me in his busy schedule but he went above and beyond what I could have expected. Replaced 2 sensors, topped off the oil, changed fuel and air filters...and when that didn’t work ran diagnostics and stayed with it till it was solved. His prices were very reasonable and he did all this knowing I was not a candidate for future business being from out-of state. I have referred him to the Cheyenne-based business that employs my son. If they are smart they will send their fleet trucks to George! Thanks George and “Dirt”!

Are your fleet vehicles equipped with four-wheel or all-wheel drive? More and more, companies are moving towards vehicles equipped with one or the other - they’re safer and more useful, particularly in inclement weather or less than ideal conditions. If your fleet is powered by all four wheels, Mr Diesel & Auto Repair in Cheyenne, WY has you covered.
