We bring the fix straight to you: air leaks, coolant loss, forced regens, wiring shorts, and other road-killing issues. Because breakdowns rarely happen in perfect spots. More often, it’s along I-80 near exit 123, or on a rain-slicked ramp outside Cooks Run when your dash lights up with a DEF warning. That’s when our mobile diesel units roll out. Every truck carries tools, diagnostics, and stocked parts so we can chase down the fault and get your rig breathing again. You’ll see us in muddy lots, rest areas, and truck stops all across Cooks Run County, turning wrenches under floodlights.
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 Cooks Run 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.
If your search history reads "Diesel Mechanic near me," chances are something's leaking, grinding, or refusing to start, and you need real help fast. We’re close to I-80, which means we can reach you quickly and be fully stocked to do more than just look. Our trucks carry the tools for the job, and our techs don’t just inspect. They fix. We handle work on all types of diesel engines, and we’re ready for more than just code scans.
If not, we’ll pull you to the shop ourselves: no third-party handoff, no waiting on another truck. Inside, our technicians cover everything from oil changes and brake replacements to wiring repairs and computer diagnostics. It’s a full-service setup, tuned for heavy diesel work. You can count on us for clear communication and repairs that last long past the first run after the fix.
At our Dale Road shop, trucks come in beat up from the road: tired tires, cracked lines, rusted bolts, and seized brakes. Just name it, we’ve seen it all. The building itself feels like a second home for diesel techs, with bays lined with welding rigs and shelves stacked with new and retread tires in every size from LP22.5 to 445/50R22.5. This is where the challenging jobs happen: structural repairs, frame rail swaps, axle spindle replacements, and complete engine rebuilds. Each step is about getting rigs back to running condition without shortcuts.
We’ve been turning wrenches in central Pennsylvania long enough to know that every hour off the road hits your bottom line. That’s why our process is streamlined from check-in to completion. We coordinate directly with your fleet manager or insurance rep and keep updates flowing. The sooner you roll out of our lot, the sooner you’re earning again. And we love that for you!
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 Cooks Run’s trusted name in diesel repair for decades.
