Parts for your 2018 Mazda Cx-5-Engine mount

2018 Mazda CX-5 engine mount: purpose, checks, and when to replace

Engine mounts are absolutely fitted to the 2018 Mazda CX-5. Technical documentation confirms this: the Mazda CX-5 (KF) Workshop Manual includes procedures for engine mounting rubber removal/installation, and Mazda’s electronic parts catalogue lists multiple mounts (right-hand engine mount, left-hand trans mount, and torque/roll mounts) for the 2017–2021 KF series. These sources make it clear the component is relevant and used on this model, whether it’s the Skyactiv-G petrol or Skyactiv-D diesel variant.

On this CX-5, the engine mounts support the weight of the engine, keep it centred under the bonnet, and isolate vibration so the cabin stays quiet and comfy. They also control engine rock when taking off or changing gears, protecting driveshafts, exhaust joints, and other under-bonnet gear. Many mounts are hydraulic (fluid-filled) to better cancel out vibration at idle and during light acceleration, which is why a worn mount often shows up as a buzz through the steering wheel or seats.

As part of routine servicing, a quick visual and functional check is smart. A technician will look for perished rubber, collapsed or split insulators, and any fluid seepage from hydraulic mounts. Under load, excessive engine movement or a clunk on take-off or when shifting from Reverse to Drive can point to a tired mount.

• Common signs: more vibration at idle with the air-con on, thuds on acceleration or over bumps, and noticeable engine shudder on start-up/shut-down.
• Typical lifespan can vary from about 80,000 to 150,000 km, depending on driving, heat, and contamination from oil leaks.
• If one mount has clearly failed, it’s worth assessing the rest, companion mounts can be stressed and close to the end of their life.

Replacement on a CX-5 involves safely supporting the engine, loosening brackets and crossmembers as specified, and torquing fasteners with the engine settled at normal ride height. Using genuine or quality aftermarket mounts helps keep NVH to factory levels. After any oil leaks are repaired, re-check mounts at the next service, as rubber can deteriorate quickly once soaked. A healthy set of mounts keeps the Mazda feeling tight, smooth, and quiet on Aussie and Kiwi roads.

FAQs

How many engine mounts does a 2018 Mazda CX-5 have?
Most 2018 CX-5 variants use four mounts: a main right-hand engine mount, a left-hand transmission mount, plus front and rear torque (roll) mounts. Exact hardware can vary slightly by engine and drivetrain, but the setup is designed to support weight and limit engine rock without sending vibration into the cabin.

How long do CX-5 engine mounts last, and when should they be replaced?
Many last well past 100,000 km, but heat, stop–start commuting, and oil contamination can shorten that. If there’s increased vibration at idle, clunks on take-off, or visible cracking or fluid leakage from a mount, it’s time to have them assessed. A technician can confirm with a load test and inspection during a routine service.

Is it safe to drive with a worn engine mount?
Short trips might be possible, but it’s not ideal. A failed mount can let the engine move more than it should, which can stress exhaust flex joints, hoses, and driveshafts, and it can make the car feel rough or thumpy. It’s best to book a repair promptly to keep the CX-5 smooth and protect related components.
