NewYall 72mm Throttle Body for 3.0L/3.6L V6 GM Engines — Direct-Fit for Buick, Cadillac, Chevy (72mm, OEM Match)

NewYall 72mm throttle body engineered for 3.0L and 3.6L V6 GM vehicles delivers precise airflow control and direct-fit compatibility for a range of Buick, Cadillac, GMC and Chevrolet models.

This replacement throttle body is a direct-fit service part designed to match the factory bore diameter and mounting points for many GM V6 applications. Built to the 72mm specification, it is intended for vehicles equipped with 3.0L or 3.6L V6 engines and replaces worn or malfunctioning throttle units to restore reliable throttle response and idle control. Use this unit when diagnosing throttle-body related drivability issues, or as a preventative fresh part during engine service.

Which vehicles and engines does this throttle body fit?

This throttle body is specifically sized and calibrated for 3.0L and 3.6L V6 engines across several GM brands. It is not universal; verify model year and engine displacement before ordering to ensure fit and function.

• Buick: Enclave (2012–2020), LaCrosse (2012–2019)
• Cadillac: CTS (2012–2019), SRX (2012–2016), XTS (2013–2016), ATS (2013–2019)
• GMC: Canyon (2015–2020), Terrain (2012–2017), Acadia (2012–2020)

How does the 72mm bore size affect performance and fit?

The 72mm bore diameter matches factory specifications for the targeted 3.0L/3.6L V6 engines, ensuring correct airflow dynamics and throttle response. Using the correct bore prevents air metering errors and helps maintain intended engine calibration.

• 72mm bore calibrated to original equipment airflow characteristics
• Direct-fit bolt pattern and connector placement for easier swap
• Reduces need for ECU relearn when installed per manufacturer procedure

What should I inspect before replacing my throttle body?

Before replacing the throttle body, verify that symptoms are not caused by intake leaks, dirty throttle plates, or sensor faults. A visual check and basic diagnostic steps help confirm the throttle body is the source of problems like rough idle or intermittent throttle response.

• Check for vacuum or intake hose leaks and damaged gaskets
• Inspect throttle plate for carbon buildup; clean if necessary
• Scan for trouble codes and confirm TPS/idle control circuit readings

How straightforward is installation and what accessories might I need?

Installation is intended to be straightforward for technicians or experienced DIYers; it typically requires removing the intake duct, unbolting the old unit, and transferring any sensors or gaskets. Always use a new gasket and follow torque specs to prevent air leaks and ensure a secure fit.

• Expect standard hand tools, torque wrench, and new throttle body gasket
• Reconnect electrical harnesses and clear codes or perform ECU relearn if required
• Professional installation recommended if you lack diagnostic tools or experience

Who is this for: The NewYall 72mm throttle body is intended for owners and mechanics servicing GM vehicles with 3.0L or 3.6L V6 engines listed above. Choose this part if you need a direct-fit replacement to restore proper throttle operation, replace a failing actuator, or maintain correct engine air metering during routine repairs. It is not compatible with four-cylinder or other displacements — confirm engine size before purchase.
