Parts for your 2010 Honda Accord-Engine mount

2010 Honda Accord engine mount — purpose, upkeep, and when to replace

Technical references including the Honda Accord 2008–2012 Service Manual (Helm) and the OEM Honda parts catalogue confirm the 2010 Honda Accord is fitted with multiple engine mounts. Depending on engine and transmission, there are typically four mounts (right/engine side, left/transmission side, front and rear torque mounts), most of them liquid-filled (hydraulic), with vacuum control on some 2.4-litre variants.

On this Accord, engine mounts secure the engine and transmission to the subframe while isolating vibration so the cabin stays quiet and comfortable. They also keep the driveline aligned, which protects CV joints, exhaust flex sections, and hoses. The hydraulic design uses fluid to absorb harshness, and some models use a vacuum-controlled front mount that firms up under certain conditions (like at idle with the A/C on) to cut buzz and vibration.

Mounts aren’t a scheduled replacement item, but they do wear. As part of routine servicing, it’s smart to inspect them every 40,000–60,000 kilometres. A technician will look for perished or cracked rubber, a collapsed mount, fluid weeping from hydraulic mounts, and split vacuum lines to the front mount (where fitted). Common symptoms of a tired mount include:

• Noticeable vibration at idle or when selecting Drive/Reverse
• Clunk or thud on take-off, braking, or gear changes
• Excessive engine movement under the bonnet
• Visible fluid on or around a mount body

When replacement’s due, using quality hydraulic mounts specified for the exact engine (2.4L or 3.5L) and transmission is important. Under the bonnet, the engine must be safely supported from above or below, fasteners loosened, height adjusted to relieve load, and bolts torqued at normal ride height. It’s good practice to replace severely worn torque mounts in pairs, check the vacuum switching valve and hoses on vacuum-assisted systems, and verify idle quality after the job. A wheel alignment check can be worthwhile if the subframe was shifted.

Typical labour time ranges from about 1.5 to 3.5 hours per mount depending on which one and workshop setup. Driving long-term with a failed mount can stress the exhaust, axles, and shifter cables, so sorting it early usually saves money and keeps the Accord feeling tight and refined.

Popular questions about 2010 Honda Accord engine mounts

How many engine mounts does a 2010 Accord have?
Most 2010 Accords have four: right engine mount, left transmission mount, and front and rear torque mounts. Some trims use a vacuum-assisted hydraulic front mount. Exact configuration varies with 2.4L versus 3.5L and auto/manual gearboxes.

What are the signs of a failing engine mount?
Owners typically notice increased vibration at idle, a thud when taking off or shifting, and more engine movement when blipping the throttle. On hydraulic mounts, fluid stains are a giveaway. If the mount uses vacuum control, cracked hoses can mimic a failed mount with roughness at idle.

Can they drive with a worn mount, and how long does replacement take?
Short trips are usually fine, but prolonged driving can accelerate wear on the exhaust flex joint and CVs. A single mount replacement is often 1.5–3.5 hours depending on which mount and workshop equipment.
