Parts for your 2018 Honda Odyssey-Engine mount

2018 Honda Odyssey engine mount — purpose, care, and replacement tips

Technical sources confirm that engine mounts are absolutely fitted to the 2018 Honda Odyssey (RL6). The Honda factory service manual details multiple mounts and an Active Control Engine Mount (ACM) system, and OEM parts catalogues list front, right, and rear engine mounts for this model. That means the engine-mount is relevant and serviceable on the 2018 Honda Odyssey.

The 2018 Honda Odyssey relies on a set of mounts to hold the 3.5‑litre V6 in place while keeping the cabin smooth and quiet. These include hydraulic mounts and an active (vacuum‑controlled) rear mount designed to cancel vibration—especially important when the Odyssey’s cylinder deactivation system is at work. In plain terms, the mounts anchor the engine, control torque movement under load, and isolate buzzy vibes from the body so the people mover stays calm and comfy.

As rubber and fluid-filled components, engine mounts wear over time. Regular servicing should include a visual and functional check: look for cracked rubber, collapsed mount height, or oily residue from a leaking hydraulic mount. Technicians also listen and feel for tell-tales such as a shudder at idle in Drive with the A/C on, thumps when shifting from Reverse to Drive, or excess engine movement when blipping the throttle. On this Odyssey, the rear active mount is a common wear item due to the extra work it does managing vibrations.

There’s no fixed kilometre replacement interval, but many mounts start to show their age anywhere from 100,000 to 180,000 km depending on conditions. If any mount is failed, timely replacement protects adjacent components (exhaust flex joints, driveshafts, and even the transmission) from extra stress. Quality OE or OE‑equivalent mounts are strongly recommended, as the active system relies on the correct durometer and internal valving to keep things civilised.

When replacing a mount, the engine should be safely supported, and fasteners torqued to factory specs with the drivetrain at normal ride height (to avoid pre-loading the rubber). On models with the Active Control Engine Mount, ensure vacuum lines and control solenoids are routed correctly, and perform an idle relearn after battery disconnection so the control strategy behaves as intended. A brief post-repair road test to verify idle smoothness, take-off feel, and shift quality is good practice. Look after the mounts and the Odyssey rewards with that quiet, relaxed manner families expect across Aussie and Kiwi roads.

• Common signs of a worn mount: harsh idle in Drive, clunks on take-off, visible cracks or fluid seepage, and unusual engine movement.
• Service tip: inspect mounts at each scheduled service interval and whenever driveline vibration complaints arise.

Popular questions about 2018 Honda Odyssey engine mounts

How long do engine mounts typically last on a 2018 Odyssey?
Many owners see 100,000–180,000 km from the original mounts, though stop–start urban driving, heat, and towing can shorten that. The rear active mount often ages first because it does the heavy lifting to keep idle and low‑speed vibration in check. Regular checks during routine servicing help catch early wear before it affects drivability.

What are the symptoms of a failing engine mount on this model?
Expect a rougher idle in Drive (especially with the A/C on), thumps when shifting between Reverse and Drive, a knocking sensation on take‑off, or visible sagging/cracks in the mount. If the rear active mount loses function, the vehicle may feel buzzy when the engine drops cylinders at light throttle. Any of these signs warrants a closer inspection.

Does the active engine mount need special setup after replacement?
No coding is required, but correct vacuum hose routing and intact control solenoids are essential. After battery disconnection or mount work, performing an idle relearn helps the engine and mount control settle into smooth operation. A short test drive to verify idle quality and low‑speed refinement is recommended.
