Computer diagnostics for engine codes Belt, hose, and leak repairs Turbocharger troubleshooting Oil and filter changes Engine performance optimization Advanced Diagnostic Technology
We invest in the latest diagnostic equipment to accurately identify and resolve engine issues on-site, saving you time and money.
OEM-Level Software
We use manufacturer-specific diagnostic software for Cummins, Detroit, Caterpillar, International, and more. This gives us the same capabilities as dealership technicians.
- Read and clear fault codes
- View live engine data
- Perform calibrations
- Update ECM programming
Multi-System Scanning
Our equipment doesn't just read engine codes - we can diagnose transmission, ABS, aftertreatment, and body control systems all in one visit.
- Engine management systems
- Emission control systems
- Transmission controllers
- Safety system diagnostics
Real-Time Analysis
We perform live data monitoring to catch intermittent issues that don't always trigger codes. This helps us identify problems before they cause breakdowns.
- Fuel pressure monitoring
- Boost pressure analysis
- Temperature tracking
- Performance data logging
Common Engine Problems We Solve
From simple fixes to complex diagnostics, here's how we approach the most frequent engine issues:
Check Engine Light
Don't ignore that warning light. We'll read the codes, diagnose the root cause, and explain exactly what's happening. Often, we can fix it on the spot - whether it's a sensor, emission issue, or engine parameter.
Loss of Power
When your truck feels sluggish or won't pull loads like it used to, we systematically check fuel delivery, turbo operation, air intake, and ECM settings to restore full power.
Hard Starting
Cold morning won't start? Taking multiple attempts? We diagnose fuel system pressure, glow plug operation, battery condition, and starter performance to get you starting reliably.
Excessive Smoke
Black, white, or blue smoke tells a story. We identify whether it's incomplete combustion, coolant intrusion, or oil burning, then provide solutions to clean up your exhaust.
Overheating Issues
Running hot can quickly damage an engine. We check coolant flow, radiator condition, fan operation, and head gasket integrity to keep temperatures in the safe zone.
Fuel Economy Drop
When MPG drops suddenly, something's wrong. We analyze injection timing, air filter condition, turbo efficiency, and driving parameters to restore your fuel economy.
Our Diagnostic Process
We follow a systematic approach to ensure accurate diagnosis and efficient repairs:
Initial Communication
When you call, we ask about symptoms, when they occur, and any recent changes. This helps us bring the right tools and parts for faster service.
Visual Inspection
Upon arrival, we perform a thorough visual check for obvious issues like leaks, damaged components, or loose connections that might be causing problems.
Computer Diagnostics
We connect our diagnostic equipment to read fault codes, view freeze frame data, and monitor live engine parameters to pinpoint issues.
Physical Testing
Beyond computer diagnostics, we perform hands-on tests like compression checks, pressure tests, and component functionality verification.
Clear Explanation
We show you what we found, explain it in plain language, and discuss repair options. You'll understand exactly what's wrong and what it takes to fix it.
Efficient Repair
With your approval, we complete repairs using quality parts. We then clear codes, test drive if needed, and verify the problem is resolved.
Our Transparency Promise
No Mysteries, No Surprises
Engine problems can be stressful, especially when you don't understand what's wrong. That's why we make transparency our top priority. We believe you should understand your truck as well as we do.
Education is Part of Our Service
We'll show you diagnostic results on our equipment, explain what the codes mean, and even point out the problematic components. If you're interested, we'll teach you warning signs to watch for in the future.
Options, Not Pressure
Sometimes there's more than one way to solve a problem. We'll explain the pros and cons of each approach - from temporary fixes to permanent solutions - so you can make the best decision for your situation.
What This Means For You:
- See actual diagnostic data from your engine
- Understand exactly what needs repair and why
- Know potential future issues we've spotted
