When the dash lights up, the clock starts ticking. We have no time to lose. Our mobile mechanics load up and roll out, ready to tackle the problem where it happened: on an icy grade, in a pull-off by the weigh station, or outside a logging site where cell service barely holds. Some days it’s a coolant hose that splits open mid-run; other days, it's an air leak that drains the system before the brakes release. We’ve chased these problems in every season, often with snow hitting sideways or summer heat bouncing off the asphalt.
Each service truck carries everything needed to diagnose and repair on-site, including electrical gear, air fittings, spare hoses, and stocked tires. If the fix needs more room, we tow the truck to our Guenot Settlement facility and move straight into the teardown process. Engines, radiators, and turbo systems get pulled and rebuilt by the same crew that answered the call. No delay. No handoff. Just work done until the truck moves again.

You don’t need to search far for a Diesel Mechanic who actually shows up prepared. We’ve built our business on rolling directly to you with everything necessary to diagnose and fix the issue roadside. Our mobile crews know the roads between Guenot Settlement and Guenot Settlement by heart. They’ve handled mid-haul breakdowns outside Falls Creek, after-hours calls in Luthersburg, and long-wait turnarounds off exit 120. If the truck can be fixed where it stands, we’ll make it happen right there.
We stay in tune with the rhythm of the road. Drivers call because they know what to expect—fast answers, no runaround, and fixes that hold past the next weigh station. Some of our calls start with a stressed dispatcher and end with a driver back behind the wheel before dawn. Others turn into repeat routes, familiar faces, and quick nods at the pump the next time through town. Around here, word travels fast when a crew keeps trucks moving.
Step inside, and you’ll hear work in motion: lifts humming, wrenches hitting steel, air lines snapping into place: it’s the sound of trucks getting ready for the next run. Our bays handle the big jobs that roadside service can’t: engine tear-downs, turbo swaps, radiator installs, suspension rebuilds, and wiring overhauls. Each stall is stocked for heavy diesel repair, from axle work to full structural restoration. Nothing sits idle here.
We’ve earned Guenot Settlement’s trust by fixing what others misdiagnosed. That’s why independent haulers, local companies, and even other shops send diesel work our way. Cooling system failing under load? Exhaust throwing codes with no apparent cause? We’ll chase it down and explain the fix. Not upsold, not brushed off, just straight diesel repair, built for people who actually rely on their trucks to make a living.
Bigler Boyz handles diesel like it’s supposed to be handled: hands-on, with no steps skipped. And you’ll also find preventive work in the mix: oil changes on schedule, coolant system checks before summer hits, and winter prep that doesn’t just stop at fuel conditioner. We know what local roads and hills can do to a poorly maintained rig, and we help you stay ahead of it. That’s why we’ve been Guenot Settlement’s trusted name in diesel repair for decades.
