Parts for your 2009 Honda Odyssey-Engine mount

2009 Honda Odyssey engine mount — purpose, care and replacement

Technical sources confirm the 2009 Honda Odyssey absolutely uses engine mounts. The Honda service manual for the 2005–2010 Odyssey platform and OEM parts catalogues list a vacuum-controlled active hydraulic front engine mount, along with rear and side mounts. Honda technical bulletins for this generation also discuss vibration concerns and leakage from the active front mount. So yes—engine mounts are fitted and they’re important to drivability and comfort.

On the 2009 Odyssey, the engine mounts do the heavy lifting of holding the J35 V6 in place while soaking up vibration so the cabin stays calm. The active hydraulic front mount changes stiffness using engine vacuum to smooth out shake at idle and during take-off, while the rear and side mounts keep the drivetrain aligned under braking, cornering, and towing. Healthy mounts protect other bits too—CV joints, exhaust flex, and even the subframe—by limiting excessive engine movement.

There’s no set replacement interval, but mounts are wear items. In local conditions, many owners see 100,000–160,000 km before noticeable degradation, though leaks or vacuum issues can bring that forward. As part of routine servicing, a quick visual and functional check is smart: look for cracked rubber, collapsed mount height, hydraulic fluid weeping, perished vacuum hoses on the front mount, and any thump when shifting from R to D.

• Common signs it’s time: extra vibration in Drive at a standstill, steering wheel buzz, a clunk on acceleration or lift-off, and visible fluid around a mount.
• If the front active mount fails, vibration often gets worse with A/C on or when stopped at lights.

Replacement advice for this model: use quality hydraulic/active mounts matched to Odyssey specs (and VCM where fitted). Check vacuum supply and the mount control solenoid when doing the front mount—no point fitting a new unit if it’s not being actuated. Support the engine properly, fit new hardware where specified, and torque fasteners at normal ride height to avoid pre-loading the rubber. After work, an idle relearn can help smooth things out. Typical labour is 1.5–3.0 hours depending on which mount and workshop setup.

Leave it too long and the extra engine movement can stress driveshafts, hoses and exhaust, so sorting mounts early can save money and keep the Odyssey feeling tight and quiet on Aussie and Kiwi roads.

FAQs

How long do engine mounts last on a 2009 Odyssey?
Many see 100,000–160,000 km, but it varies with driving, heat, and fluid leaks. The active front mount tends to be the first to show wear because it works hardest at idle and take-off.

Is it safe to drive with a worn engine mount?
Short term, usually—though comfort and smoothness suffer. Long term, extra engine movement can damage driveshafts, exhaust components, and other mounts, so it’s best to repair sooner than later.

Does the 2009 Odyssey have an active mount?
Yes. It uses a vacuum-controlled active hydraulic front mount to reduce idle and low-speed vibration. If vacuum lines or the control solenoid are compromised, the mount won’t do its job even if the rubber is fine.
