2014 Mazda CX-9 Engine Mount: What It Does and When to Replace It

Based on Mazda’s workshop service information for the 2014 CX-9 and the Mazda electronic parts catalogue, this model is absolutely fitted with engine mounts. The 3.7‑litre V6 sits on a set of rubber/hydraulic mount insulators and a torque mount (roll stopper), with a separate transmission mount, all designed to control movement and keep noise, vibration and harshness in check. So yes—engine mounts are relevant and used on the 2014 Mazda CX-9.

On this CX-9, the engine mounts do a few key jobs: they support the weight of the V6, isolate vibrations so the cabin stays quiet, and limit how far the engine can rock when taking off, shifting gears or hitting bumps. Hydraulic-style mounts (used in key positions on the CX-9) are tuned to soak up specific frequencies, which is why a healthy set makes the car feel refined at idle and on the motorway.

There isn’t a fixed service interval for engine mounts, but they should be checked during routine servicing—especially as kilometres climb. Many owners start to notice extra buzz through the steering wheel or seats between 100,000–180,000 km as mounts age. Heat, oil exposure and normal torque loads gradually break down the rubber or the fluid inside hydraulic mounts.

• Common signs it’s time to replace one or more mounts:
  • Noticeable vibration at idle (often worse in Drive with the A/C on).
  • Clunk or thud when shifting from Reverse to Drive.
  • Engine movement when blipping the throttle under the bonnet.
  • Cracked rubber or fluid seepage from a hydraulic mount.

When replacing, support the engine properly with a jack and timber block under the sump, follow torque specs, and tighten through-bolts with the drivetrain settled at normal ride height. If the rear mount requires subframe loosening, a wheel alignment may be wise afterwards. It’s smart to use quality OEM or reputable aftermarket hydraulic mounts—solid or poorly tuned mounts can increase NVH and make the CX-9 feel coarse.

If one mount has failed, have the others inspected at the same time, including the transmission and torque mounts. Fresh mounts restore smoothness, protect the exhaust and driveline from excessive movement, and make the big Mazda feel like it should—quiet, composed and confident.

FAQs

How many engine mounts does a 2014 Mazda CX-9 have?
The CX-9 typically uses multiple mounts: a right-hand (engine side) mount, a left-hand transmission mount, at least one hydraulic mount at the front or rear, and a torque/roll mount. The exact count and layout can vary slightly by market and build, but it’s a multi-mount system designed to control both support and rotation.

What are the classic symptoms of a failing CX-9 engine mount?
Owners often report a shake at idle, a thump when shifting between Reverse and Drive, or more engine movement than normal under the bonnet. Hydraulic mounts may leak fluid, and cracked rubber is a giveaway. If vibration improves when shifting to Neutral at a stop, that’s another hint a mount is tired.

How much does replacement cost in Australia or New Zealand?
As a ballpark, quality mounts can range from roughly AUD/NZD $200–$500 each depending on position and brand. Labour will vary by mount: 1.5–3.0 hours is common, with the rear/hydraulic positions often taking longer. A single mount job may land around AUD/NZD $400–$900 supplied and fitted, multiple mounts done together will scale accordingly.
