Paccar EGR Valves
Paccar EGR valves are key components in the emissions control system used on modern Paccar diesel engines. The exhaust gas recirculation (EGR) valve regulates the amount of exhaust gas redirected into the intake system to reduce NOx emissions and maintain stable combustion temperatures. At Advanced Truck Parts, we supply replacement EGR valves for Paccar MX-11 and MX-13 engine platforms.

Paccar EGR Valves by Engine Platform
Paccar engines used in Kenworth and Peterbilt trucks rely on electronically controlled EGR valves as part of the emissions system. Proper EGR valve operation helps regulate exhaust gas flow, maintain combustion efficiency, and prevent emissions-related fault codes.
Paccar MX-13 EGR Valves
The Paccar MX-13 engine is widely used in heavy-duty Kenworth and Peterbilt trucks. These engines use an advanced emissions system that includes an electronically controlled EGR valve to regulate exhaust gas flow.
- Paccar MX-13 EPA10 engines
- Paccar MX-13 EPA13 engines
- Kenworth and Peterbilt highway truck platforms
A failing MX-13 EGR valve can lead to rough engine operation, emissions fault codes, or engine derate conditions.
Paccar MX-11 EGR Valves
The Paccar MX-11 engine is commonly used in regional haul and weight-sensitive applications. Its emissions system includes an EGR valve designed to regulate exhaust gas recirculation and control combustion temperatures.
- Paccar MX-11 regional haul engines
- Paccar MX-11 vocational truck platforms
Correct EGR valve replacement ensures proper airflow balance and stable engine performance.
Common Paccar EGR Valve Failure Symptoms
- Check engine light related to the EGR system
- Rough idle or reduced engine performance
- Excessive soot buildup
- Engine derate conditions
- Increased emissions levels
If an EGR valve fails, the engine may not properly regulate exhaust gas flow, which can affect both performance and emissions system operation.
Verify Fitment Before You Buy
Paccar EGR valves must match the engine model and emissions configuration. To confirm compatibility before ordering, provide:
- Engine Serial Number
- Truck year / make / model
- Engine model (MX-11 or MX-13)
- Current EGR valve part number
This information allows our team to confirm the correct EGR valve for your Paccar engine.
