Citumo Engine Motor Mount for Chevy GMC Cadillac 15854939 — Front Mount with Heat Shield, OE Fit for 2007–2014 V6/V8

Citumo Upgrade Engine Motor Mount 15854939 is a direct-fit front motor mount (left or right) with heat shield engineered to replace worn OE mounts on select Chevy, GMC and Cadillac V8/V6 trucks and SUVs.

When engine mounts age the bonded rubber hardens and vibration control drops, making driving noisier and increasing stress on driveline components. This Citumo replacement is designed to match factory fitment and restore proper engine support for 2007–2014 GM platforms listed in the compatibility notes. It arrives with a heat shield and direct OE cross-reference numbers so installers can confirm fitment quickly and reduce bench time.

How does this mount restore ride comfort and driveline stability?

The mount uses new engineered rubber and a durable metal housing to absorb engine movement and minimize vibration transmitted to the chassis. By replacing a hardened, worn mount you reduce engine rocking under load, improve shifting feel, and decrease noise inside the cabin. Properly functioning mounts also limit stress on adjacent components like exhaust and transmission brackets.

• New molded rubber improves vibration damping
• Rigid metal shell aligns to factory mounting points for correct geometry
• Heat shield protects rubber from exhaust and underhood heat sources

What should a technician know before installation?

Installation is straightforward for a trained mechanic but observe a few practical notes: this part includes a heat shield that can affect bolt alignment, so remove or loosen the shield if bolts won’t line up. Always torque fasteners to manufacturer specs and inspect surrounding mounts and hardware for wear while the vehicle is lifted.

• Package includes one front left or front right motor mount with heat shield
• If bolts won’t align, loosen/remove the heat shield per instructions
• Check and replace companion mounts or hardware as needed during service
