Not Sure What It Needs?

Where we work
X-Pert Fleet Solutions provides mobile commercial truck repair, fleet maintenance, diesel diagnostics, heavy equipment repair, and hydraulic services at customer facilities, fleet yards, and job sites. We do not provide roadside assistance or perform repairs on public roadways, highway shoulders, or interstate highways.
Diesel Engine Repair
Diesel diagnostics that find the actual problem.
Derates, warning lights, hard starts, power loss, smoke, fuel issues — diesel problems get expensive fast when shops guess. Our mobile diesel mechanics serve Melbourne, Palm Bay, and all of Florida's Space Coast: we diagnose first, quote straight, and repair what's actually broken.
Fuel Systems
Injectors, high-pressure pumps, lift pumps, filters, lines, and contamination cleanup on common-rail systems — including CP4 failures.
CP4 Services →Electrical & No-Starts
Cranking and charging systems, wiring faults, corroded grounds, parasitic draws, sensor failures, and intermittent electrical gremlins.
Request Service →Derates & Fault Codes
Check-engine lights, limp mode, and emissions-related derates diagnosed with proper scan tooling and live data — not code-clearing and hoping.
Request Service →Cooling & Mechanical
Overheating, coolant loss, belts, hoses, water pumps, and the mechanical wear items that take diesels down under load.

Our Approach
Diagnose first. Then repair.
Throwing parts at a diesel is how a $400 problem becomes a $4,000 invoice. Our process is built to protect your repair budget:
- Scan data, live readings, and physical testing before any quote
- The actual cause identified and explained in plain language
- A written quote before repairs begin — approved by you
- Repairs documented per unit for your fleet records
If a repair isn't worth doing on a given truck, we'll tell you that too. Fleet managers make better calls with honest numbers.

Engines We Work On
Trucks, vans & equipment diesels.
Ford Powerstroke, RAM Cummins, GM Duramax, the diesel and gas engines in box trucks, vans, and medium-duty commercial vehicles — plus the diesel engines in skid steers, excavators, generators, and other heavy equipment.
Known Failures — Fixed at a Flat, Installed Price
Some diesel failures are not bad luck — they are engineered-in weak points that take out engines, fuel systems, and transmissions on schedule. We fix those before they cost you a truck: 6.7L Powerstroke CP4 pumps, 6.7L Cummins grid heater bolts, LML Duramax CP4 pumps, and 68RFE cooler bypass valves. See known failures and pricing →
6.7L Powerstroke CP4
Prevention kits from $1,400, DCR pump conversion at $4,700, and full post-failure fuel system rebuilds. Fits 2011–2024 Ford 6.7L.
CP4 & DCR Services →6.7L Cummins Grid Heater
Banks Monster-Ram intake and Killer Grid Heater upgrade — removes the bolt that drops into cylinder six. $1,950 installed, on sale now, against $32,650 for a replacement engine.
Grid Heater Fix →LML Duramax CP3 Conversion
Retire the CP4.2 on a 2011–2016 6.6L LML before it grenades the fuel system. No-tune CP3 conversion from $4,700 installed, or the full contamination kit at $12,000.
CP3 Conversion →68RFE Cooler Bypass
The factory thermal bypass chokes cooler flow and cooks the transmission. Billet full-flow replacement from $500 installed, with deep pan bundles at $1,500.

Questions
About our services.
Can you do a full PM service on site, or only small repairs?
Full PM service on site. A visit covers engine oil and filter, fuel and air filters, all fluids, brake measurement, battery and charging checks, belts, hoses, steering, suspension and driveline inspection, tyres across every axle, and leak checks — finishing with written findings.
Multiple units in one visit is normal and keeps the cost per truck down.
What diesel engines do you work on?
Ford Powerstroke, RAM Cummins, and GM Duramax, plus the diesel and gas engines in box trucks, vans, and medium-duty commercial vehicles — and the diesel engines in skid steers, excavators, generators, and other heavy equipment.
We also specialise in the documented factory failure points on those platforms, at flat installed prices.
My truck is in a derate or limp mode. Can you fix it at our yard or job site?
Usually, yes. Derates, check-engine lights, and emissions faults are diagnosed with proper scan tooling and live data rather than clearing codes and hoping. Once we know the actual cause, most repairs are completed right there at your yard, fleet facility, or job site.
If a repair genuinely needs a shop environment, we will tell you that up front rather than burning your money on a visit that can't finish the job.
Do you do welding and fabrication?
Yes — minor fabrication, bracket repair, structural repairs, equipment attachment repairs, and trailer or body repairs.
It is field-level work rather than a fab shop, so tell us what you need and we will say honestly whether it is in scope.
How quickly can you get to a unit that's down at our yard?
Units that are down at your yard, fleet facility, or job site get priority on our schedule. Call (321) 312-7430 and we will give you a straight answer on timing rather than an optimistic one.
We are not a 24-hour emergency service. Our hours are Monday to Thursday 8am–4pm and Friday 10am–4pm, with weekends by appointment, and an after-hours visit to your yard or job site, when we can schedule one, carries a $250 after-hours fee.
Get it fixed at your yard or job site.
Tell us the unit, the symptom, and your yard or job site address — we'll handle the rest.
