NH Repairs provides diesel engine repair and diagnostics for commercial trucks in Deerfield Beach and northern Broward County from our shop at 2221 NW 22nd St in Pompano Beach — less than 10 minutes south on I-95. Deerfield Beach sits at the convergence of I-95 and the Florida Turnpike, making it a high-traffic point for commercial freight moving between Palm Beach and Broward counties. High-cycle corridor operation puts real demands on diesel engines, and we're close enough to respond quickly when something goes wrong.
We work across all major diesel platforms and specialize in aftertreatment and emissions systems — the most common source of unplanned downtime for fleets running South Florida's freight corridors. We diagnose first, then repair — no guesswork, no unnecessary parts.
Diesel Repair Services
Diesel Engine Diagnostics
Full diagnostic scans across Cummins, Detroit Diesel, Paccar MX, CAT, Volvo D-series, Mack, and other major commercial platforms. We pull codes, trace root causes, and give you a clear repair plan before any work starts.
Aftertreatment and Emissions Systems
DPF cleaning and replacement, EGR repair, SCR system service, DEF injector work, and diesel oxidation catalyst repair. Trucks running the I-95 corridor through Deerfield Beach, Boca Raton, and into Palm Beach County accumulate significant aftertreatment wear — we resolve these failures completely rather than clearing codes and sending trucks back out.
Fuel System Service
Injector testing, cleaning, and replacement; high-pressure common rail diagnostics; fuel pump repair; lift pump replacement; and complete fuel system diagnostics across all major diesel platforms.
Engine Overhaul and Rebuild
In-frame and out-of-frame overhauls for major commercial diesel engines. We give you an honest assessment of whether an overhaul makes financial sense before recommending one.
Cooling System Repair
Radiator repair and replacement, coolant pump service, thermostat replacement, and pressure testing. Florida heat accelerates cooling system wear — catching issues early prevents more expensive engine damage downstream.
Turbocharger Service
Turbo inspection, cleaning, rebuild, and replacement for diesel engines experiencing boost loss, excessive smoke, or power degradation.
