The Chevrolet Impala 2006-2011 3.9L Engine Motor Mount Replacement Guide is a practical reference for owners, technicians, and buyers comparing replacement parts. It walks through the full swap on the 3.9L V6: how to raise and support the car, what comes off first, how the mounts unbolt, and what to check once the new parts are in.

It also covers the buying side. Motor mounts are a left/right, engine-specific part, and ordering the wrong side or the wrong engine is the most common mistake. Verify before you pay, and keep the removed part until the new one has been test-fitted.

What to verify before ordering

Start with the vehicle year, make, model, engine or drivetrain, and the original equipment number printed on the removed part. For this job that means a 2006-2011 Impala with the 3.9L V6 — write both down before you open a single product page.

A similar-looking component can still be incompatible. Match the connector shape, mounting points, dimensions, and left/right position where applicable, confirm the seller's fitment notes, and compare against the original part before installation.

Run this checklist before you order:

• Record the VIN and exact trim level.
• Compare the OE or interchange number and connector layout.
• Check whether the part is front/rear, left/right, or a complete set.
• Inspect nearby components that could cause the same symptom.

Replacement procedure, step by step

Replacing the motor mounts on this Impala follows a fixed sequence. The engine hangs on these mounts, so the support steps are not optional. Work in order:

1. Raise and support the vehicle safely

First, safely raise and support the vehicle. Get solid supports under the car so you can work from below with both hands free — the jack lifts, the supports hold.

2. Remove the air intake assembly

Take off the engine's air intake assembly and any components obstructing access to the mounts. The intake sits in the path to the mounts, so it comes off before you touch a single mount bolt.

3. Locate the left and right mounts

The left and right motor mounts are located on each side of the engine. Identify which side you are working on before unbolting — mounting points and dimensions differ between positions, which is exactly why the pre-order checklist asks for the left/right position.

4. Support the engine from below

Use a jack to support the engine from below before you loosen anything. With the mount bolts out, the mount no longer holds the engine — the jack does.

5. Remove the old mount

Remove the bolts securing the mount to the engine and the bolts securing it to the frame. Keep the hardware sorted by location so each bolt goes back where it came from.

6. Fit the new mount and torque it

Install the new mount in reverse order and torque the bolts to factory specifications. Pull the torque values and calibration steps from the workshop manual for your exact vehicle — do not guess.

7. Check alignment and vibration

Ensure proper alignment, then run the car and check for any vibration after installation. If a warning light remains on, scan the relevant diagnostic codes and verify the repair instead of replacing additional parts at random.

Replace both mounts at the same time. The guide recommends replacing both simultaneously for balanced support — one fresh mount paired with a worn one leaves the engine leaning on the old side.

Torque, wiring and final tests

The supporting rules apply to the whole job. Disconnect power when the procedure requires it, support the vehicle correctly, and follow the workshop manual for torque values and calibration steps.

Before you close everything up, cover the basics:

• Clean mating surfaces.
• Route wiring away from heat and moving parts.
• Test the repair before returning the vehicle to service.

Specs and service facts at a glance

How to choose the right replacement

Four things decide whether a mount is worth buying:

• Verified compatibility with your year, engine, and side.
• Material quality.
• Warranty coverage.
• Clear product photos you can compare against the old part.

For safety-critical systems — brakes, steering, sensors, and fuel delivery — use the vehicle-specific specification rather than a universal substitute. Mounts are a support part; treat the spec the same way.

Keep the original part until the new component has been test-fitted and confirmed. If the new mount does not line up with the engine and frame bolt holes, you stop and compare — the reference part is in your hand.

Where to order the mount

KOEEP carries the Engine Motor Mount For 2006 2007 2008-2011 Chevrolet Impala Monte Carlo 3.5L, covering the Impala and Monte Carlo family for these years. Because this guide targets the 3.9L V6, read the fitment notes on that page against your VIN and the OE number from your removed mount before you order.

If you need more than the mount itself, the Auto & Motorcycle Parts | Koeep One-Stop Shop for Components collection pulls the full catalog into one place, so the rest of the job can ship in the same order.

Gaskets for the 3.8L family

If you also service the earlier V6 Impalas and Oldsmobiles, KOEEP lists the ECCPP Engine Gasket For 95-09 Chevrolet Impala Oldsmobile 3.8L. Match it against the engine family and year range on that page — that fitment is separate from this 3.9L mount job.

Later-generation Impala and Malibu parts

For the newer cars, KOEEP stocks the 918-806 For 14-15 Chevy Malibu Impala Engine Variable Timing Oil Control Valve. That covers the 2014-2015 generation — a different fitment range from this 2006-2011 guide, so keep the two apart when you order.

Steering wear on overlapping years

Motor mounts and steering parts wear on separate clocks. If the front end also feels loose, the Complete Guide to 4pcs Front Steering Inner & Outer Tie Rods Kit for 2000-2012 Chevrolet Impala covers the tie rod kit for years that overlap this guide.

Deeper technical reading on mount kits

If you would rather replace mounts as a kit, the 2026 technical guide covers the 2006–2011 Chevrolet Impala & Monte Carlo 3.5L/3.9L Motor & Transmission Mount Kit (4PCS) — Specs, DTC Mapping & OEM Cross-Reference, and a separate review breaks down the Engine & Trans Mount Set 6PCS for Chevrolet Impala V6 3.4L 207ci — 2026 Technical Review, DTC Mapping & OEM Cross-Reference.

Contact KOEEP before you buy

If fitment is still not clear, send KOEEP the VIN and OE number for a fitment quote before purchase. That check costs you nothing and settles the left/right and engine questions with the part in hand.

You can also write to support@koeep.com or message the team on WhatsApp with a photo of the removed part — the printed OE number gets you the fastest answer.
