Detailed Description

Westar EM-4538 is a direct-fit engine mount for select Cadillac, Chevrolet, and GMC applications. It is intended for vehicles that require a front left mount with heat shield fitment, including 2015-2020 Cadillac Escalade, 2015-2020 Chevrolet Tahoe, 2015-2020 GMC Yukon, and related Silverado and Sierra applications. The EM-4538 uses rubber and steel construction to match the demands of the specific mounting location while maintaining quality, fit, and function consistent with OEM-style replacement needs.

Westar focuses on application-specific mounts rather than universal designs, which helps ensure the part matches the vehicle’s mounting requirements. This makes EM-4538 a practical choice when replacing a worn engine mount on a Chevrolet Silverado 1500 or GMC Sierra 1500, as well as other listed GM platforms.

What This Part Helps Address

• Vibration transferred into the cabin.
• Noise caused by a deteriorated mount.
• Mounting issues related to heat shield-equipped applications.

Installation Notes and Tips

Verify the vehicle’s year, make, model, and front left mounting position before installation. Confirm heat shield requirements and compare the removed mount to EM-4538 to ensure the correct application.
