Parts for your 2015 Honda Odyssey-Engine mount

2015 Honda Odyssey engine mount — what it does and when to replace it

Engine mounts absolutely are used on the 2015 Honda Odyssey. Honda’s 2014–2017 Odyssey Service Manual details a multi‑mount setup, including an electronically controlled front “active” hydraulic mount, a rear hydraulic mount, and side mounts that support the drivetrain. Honda’s genuine parts catalogue diagrams for the 2015 Odyssey also list these mounts and related vacuum/solenoid hardware for the active system. Honda Technician Service News has covered diagnostics for active engine mounts on V6 models, reinforcing that this Odyssey relies on them to keep the cabin smooth and the drivetrain planted.

On this model, the mounts do two key jobs: they hold the J35 V6 securely in the bay and isolate vibration so the family doesn’t feel every pulse at idle or under load. The front active hydraulic mount changes its stiffness using engine vacuum and a control solenoid, tuning out low‑frequency shudder in Drive. Together with the rear and side mounts, it keeps engine movement tidy during take‑off, gear changes and hard braking.

As part of regular servicing, a quick mount check is smart—especially in Aussie and Kiwi stop–start traffic or if the vehicle tows. Look for tell‑tales like excess vibration at idle in Drive, a thud when shifting from Reverse to Drive, noticeable engine rock, or hydraulic fluid weeping from a mount. For the active system, inspect vacuum hoses and the mount control solenoid for splits, loose fittings or leaks.

• Inspection cadence: every 20,000–30,000 km or annually, and after any front‑end knock.
• Expected life: often 100,000–160,000 km, but heavy loads and heat can shorten that.

When replacement’s due, quality matters. The active front mount is tuned for this platform—cheap copies can buzz or fail early. A technician will support the engine under the sump with a block of wood, swap the mount, and only final‑torque the fasteners at normal ride height so the rubber isn’t preloaded. It’s wise to replace any collapsed mount in pairs (e.g., front and rear) to restore balance, and to renew fatigued bolts where specified by Honda. After battery disconnects, perform an idle relearn so the V6 settles nicely.

Typical labour ranges 1.5–3.0 hours depending on which mount is being changed, with the front active mount usually taking the longest. If the Odyssey has a persistent cabin shake, a clunk on take‑off, or visible mount fluid leaks, booking it in promptly protects axles, exhaust flex joints and the transmission from extra stress.

Popular questions about 2015 Honda Odyssey engine mounts

How long do engine mounts last on a 2015 Odyssey?
Many see 100,000–160,000 km, but lots of idling, towing, heat and rough roads can shorten that. Regular inspections during routine servicing catch small issues—like a weeping hydraulic mount—before they turn into big vibrations.

Is it OK to drive with a failed active engine mount?
Short trips might be possible, but it’s not ideal. Excess vibration can fatigue exhaust flex joints, hoses and wiring, and can feel pretty ordinary in the cabin. If the mount is leaking or the vacuum control is compromised, it’s best to get it sorted soon.

Does every 2015 Odyssey have an active front mount?
Yes, Australian and New Zealand–spec 2015 Odysseys use an electronically controlled front hydraulic mount with a vacuum line and solenoid. If there’s a persistent idle shudder in Drive, the mount, its vacuum hoses, or the control solenoid are common suspects.
