When a diesel truck loses pulling power, smokes unexpectedly, or surges under load, the turbocharger is often the culprit. At Paul's Repair Shop in Indianapolis, our ASE-trained technicians have diagnosed and repaired turbochargers on Class 6–8 trucks for more than a decade, giving fleet operators and owner-operators across central Indiana a reliable local resource — without the dealership wait times or dealership pricing.
Whether your rig needs a precision rebuild, a complete turbo replacement, or a wastegate actuator service, we handle everything in-house at our East 23rd Street facility. Every repair begins with a thorough turbocharger diagnostic so you only pay for what the truck actually needs.
Most turbocharger failures give early warning signs. Catching them quickly keeps a routine repair from turning into a full engine replacement. Watch for these symptoms on your diesel truck:
If your truck is showing any combination of these warning signs, calling our shop at (317) 292-8500 for a same-day turbocharger diagnostic is the fastest way to get an accurate answer and a transparent repair estimate.
Our turbocharger service goes well beyond swapping parts. Here's what every job includes:
| Service Step | What We Do | Avg. Time |
|---|---|---|
| 1. Diagnostic & Testing | Boost pressure test, visual inspection of compressor and turbine wheels, shaft play measurement, and fault code scan to pinpoint the exact failure mode. | 30–90 min |
| 2. Turbo Rebuild & Repair | Disassembly, bearing and seal replacement, shaft balancing, and housing inspection. Ideal when the compressor and turbine wheels are in good condition. | 4–8 hours |
| 3. Complete Turbo Replacement | Installation of a new or remanufactured OEM-spec turbocharger when the core is beyond economical repair. Includes oil line flush and pre-lubrication. | 3–6 hours |
| 4. Wastegate Actuator Service | Testing and replacement of electronic or pneumatic actuators that control boost pressure; prevents over-boost or under-boost conditions. | 1–3 hours |
| 5. Post-Install Verification | Road test under load conditions, live data monitoring via scan tool, and final boost pressure confirmation before returning the vehicle. | 30–60 min |
A properly functioning turbocharger is not optional on a modern diesel — it's fundamental to the engine's power output and emissions performance. Having it serviced by experienced diesel specialists delivers measurable advantages:
One of the most common questions we hear is: \"How much does a turbo cost to repair or replace?\" The answer depends on the truck make, engine platform, and the extent of damage. Below are general ranges for diesel trucks in the Indianapolis market:
| Service Type | Typical Parts Cost | Estimated Total Cost |
|---|---|---|
| Turbocharger Rebuild / Repair | $300 – $700 | $500 – $1,200 |
| Turbocharger Replacement (Reman) | $800 – $2,000 | $1,200 – $2,800 |
| Turbocharger Replacement (New OEM) | $1,500 – $4,500+ | $2,000 – $5,500+ |
| Wastegate Actuator Service | $150 – $450 | $250 – $700 |
Note: Turbocharger replacement costs vary significantly by engine type — a Cummins ISX, Detroit DD15, or Paccar MX turbocharger will be priced differently than a Ford Power Stroke or Duramax application. Call us at (317) 292-8500 for an accurate, no-obligation estimate specific to your truck.
There are plenty of shops in Indianapolis that will replace a turbocharger. Fewer will diagnose correctly, advise honestly, and back their work with confidence. Here's what sets Paul's apart:

Turbocharger problems often travel with related issues. Our shop handles the full picture:
| Service | Why It's Connected to Turbo Health |
|---|---|
| Diesel Engine Diagnostics & Repair | Turbo failure codes often co-occur with EGR and fuel system faults — a full engine diagnostic catches underlying issues. |
| Fuel Injection System Repair | Dirty injectors increase exhaust temperatures, accelerating turbocharger wear. Servicing both together extends component life. |
| EGR & DPF System Service | EGR soot buildup can restrict turbo inlet flow; a clogged DPF raises exhaust backpressure and stresses the turbine side. |
| Oil Changes & Preventive Maintenance | Fresh, clean oil is the single biggest factor in turbocharger longevity. We recommend oil analysis if turbo failure is suspected. |
| Exhaust & Emissions Repair | Exhaust leaks between the manifold and turbo inlet distort boost calculations and trigger fault codes. |
Don't let a failing turbocharger sideline your truck or your livelihood. Paul's Repair Shop offers fast diagnostics, honest estimates, and reliable repairs backed by more than a decade of diesel expertise in Indianapolis.
