On-site repair menu
FlexFix delivers a full on-site repair menu built around transparent diagnostics and factory-aligned discipline. Every visit starts with a professional assessment—not parts roulette.
Diagnostics
Computerized code scanning, live data, and check-engine / warning-light troubleshooting with clear explanations.
Brakes & suspension
Pads, rotors, calipers, shocks, struts, and steering components serviced on-site when mobile conditions allow.
Engine, starting & charging
Starters, alternators, batteries, ignition coils, and related electrical paths tested and repaired.
Cooling & climate
A/C performance, radiators, water pumps, thermostats, and cooling-system pressure checks—critical in Texas heat.
| Service focus | What you gain | Technical edge |
|---|---|---|
| Diagnostics | Pinpoints root causes; reduces repeat visits and unnecessary parts. | Structured testing paths and scan-tool workflows—not a quick code read only. |
| Brakes | Restores predictable stopping distance and pedal feel. | Installation discipline aligned with Ford/Lincoln service expectations where applicable. |
| Suspension | Stability, tire wear, and ride quality addressed together. | Suspension systems fundamentals from factory training programs. |
| Cooling | Helps prevent overheating-related engine damage in hot climates. | Pressure testing and temperature-aware inspection before major component calls. |
Diagnostic policy
We charge $60 for diagnosis, then fair labor for any work you approve—no surprises. The $60 diagnostic is not a hidden surcharge: when you approve the quoted repair, that fee is credited toward the labor for that service.
When we refer to a shop
Some jobs need a lift, clean room, or extended teardown. We refer those out so quality stays high:
- Internal transmission rebuilds (facility-dependent).
- Complete engine swaps or long-block replacements that need a lift and extended teardown space.
- Body work, paint, or structural frame repair.
What we offer — tap or hover a card for emphasis; every category is performed at your location when mobile service allows.
