Mack EGR Valves
Mack EGR valves are important components in modern diesel emissions systems. The exhaust gas recirculation (EGR) valve regulates the amount of exhaust gas redirected into the intake system to reduce combustion temperatures and lower NOx emissions. At Advanced Truck Parts, we supply replacement EGR valves for Mack MP7, MP8, and MP10 engine platforms.

Mack EGR Valves by Engine Platform
Mack diesel engines use electronically controlled EGR valves as part of the emissions control system. Proper EGR valve operation helps regulate exhaust gas flow, maintain combustion stability, and prevent emissions-related fault codes or engine derate conditions.
Mack MP8 EGR Valves
The Mack MP8 engine is widely used in Mack highway and vocational trucks. Its emissions system includes an EGR valve designed to control exhaust gas flow and maintain proper combustion temperatures.
- Mack MP8 EPA07 engines
- Mack MP8 EPA10 engines
- Mack Anthem and Pinnacle truck platforms
A failing MP8 EGR valve can cause rough engine operation, excessive soot buildup, or emissions system fault codes.
Mack MP7 EGR Valves
The Mack MP7 engine is commonly used in regional haul and vocational applications. The EGR valve works together with the EGR cooler and sensors to regulate exhaust gas flow and maintain emissions compliance.
- Mack MP7 regional haul engines
- Mack MP7 vocational truck platforms
Mack MP10 EGR Valves
The Mack MP10 engine is designed for heavy-haul and high-horsepower applications. Proper EGR valve function helps control combustion temperatures and supports the emissions system under heavy load conditions.
- Mack MP10 heavy-haul engines
- Mack MP10 high horsepower truck applications
Common Mack 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 exhaust emissions
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
Mack 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 (MP7, MP8, MP10)
- Current EGR valve part number
This information allows our team to confirm the correct EGR valve for your Mack engine.
