916 Truck Repair provides EGR valve repair in Sacramento CA for heavy-duty diesel trucks and commercial vehicles. Carbon cleaning, EGR valve replacement, cooler repair, and emission system diagnostics. Call (916) 898-9090.
The Exhaust Gas Recirculation (EGR) valve redirects exhaust gases back into the intake to reduce emissions on commercial vehicles. Over time, carbon buildup causes the EGR valve to stick or fail — triggering fault codes, rough idle, power loss, and derate conditions that reduce engine performance. 916 Truck Repair provides EGR valve repair and emission system diagnostics for heavy-duty diesel trucks throughout Sacramento CA.
Our technician diagnoses EGR valve problems using advanced scan tools and performs repairs that restore your emission system to proper function. We do not provide general repair for standard vehicles — our EGR valve repair service is exclusively for commercial trucks, semi trucks, and heavy-duty diesel vehicles. Whether your vehicle needs EGR valve cleaning, replacement, or cooler repair, our technician arrives at your location with the parts and tools to fix the problem efficiently.
Unlike general repair shop that may not understand diesel aftertreatment, we specialize in the emission systems found on Freightliner, Peterbilt, Kenworth, Volvo, International, Mack, and other heavy-duty commercial vehicles.
Carbon removal and valve restoration for EGR valves fouled by soot and exhaust deposits. Cleaning can restore function in moderately carboned valves when the valve mechanism is not mechanically damaged.
Severely carboned or mechanically failed valves require replacement. We install heavy-duty EGR valves designed for commercial diesel engines. Our technician removes the old valve, cleans the mounting surfaces, and installs the new unit with proper gasket sealing.
Coolant leaks or internal cracks in the EGR cooler cause coolant loss, white smoke, and emission system failures. We diagnose cooler condition using pressure testing and visual inspection, then repair or replace the cooler to restore emission system integrity.
Comprehensive diagnostic testing of the EGR valve, cooler, and related sensors. We read fault codes, test valve position sensors, and verify cooler flow to identify the root cause of emission system failures. Our diagnostic service ensures we fix the right problem — not just the symptom.
We operate across the greater Sacramento region and along major Northern California highway corridors. Mobile dispatch to your yard, dock, or roadside.
