Parts for your 2004 Nissan Serena-Engine mount

2004 Nissan Serena Engine Mounts

Engine mounts are absolutely fitted to the 2004 Nissan Serena (C24). Technical references including the Nissan Serena C24 Service Manual (Engine Mechanical and Automatic Transaxle sections) outline engine mounting insulators, brackets and replacement procedures, while the Nissan FAST Electronic Parts Catalog lists an “Engine Mounting” group for the C24 platform. That makes the engine mount a relevant and routine service item on this model.

On a 2004 Serena, the engine mount’s job is to hold the engine and transmission in the right spot, soak up vibration, and control fore–aft rocking during take‑off and gear changes. Most C24s use a combination of rubber and hydraulic mounts: a right‑hand (engine) mount, a left‑hand (transmission) mount, plus front and rear roll stoppers. Keeping these in good nick helps the van feel smooth, quiet and tight, which is exactly what families and shuttle operators expect.

As part of regular servicing, the mounts deserve a quick look every 40,000–60,000 km, or any time there’s extra vibration or a knock when shifting from Park to Drive. Heat, oil contamination and age can crack the rubber or leak fluid from hydraulic mounts.

• Common signs they’re tired: shudder on acceleration, harsh vibration at idle, clunks over bumps, excessive engine movement when blipping the throttle, or a humming/booming felt through the cabin.
• Inspection tips: check for perished rubber, collapsed gaps, torn torque rods, and leaked mount fluid. Make sure the exhaust flex and hoses aren’t carrying the engine’s weight.

Replacement isn’t complicated but does require care. The engine should be safely supported with a jack and a timber block, then mounts changed one at a time. Brackets and fasteners must be torqued to spec and alignment marks matched so the engine sits naturally without pre‑load. Front and rear roll stoppers can be fiddly due to subframe access, and corrosion on captive nuts is common on older vans. If the subframe is loosened, it’s smart to check wheel alignment afterwards.

For best results, use genuine or high‑quality OEM‑equivalent mounts, mixing soft and firm mounts can create odd vibrations. After fitment, expect a short bedding‑in period where idle feel improves as the rubber settles. Owners who tow or run a loaded van should inspect mounts more frequently, as extra weight and heat accelerate wear.

Popular questions about 2004 Nissan Serena engine mounts

How many engine mounts does a 2004 Nissan Serena have?
The C24 Serena typically runs four mounts: a right‑hand engine mount, a left‑hand transmission mount, plus front and rear roll stoppers. Exact designs vary slightly by engine (QR20DE petrol vs YD22 diesel) and drivetrain spec, but the four‑point arrangement is the norm.

What are the symptoms of a failing engine mount on a Serena?
Owners usually notice increased vibration at idle, a thud when selecting Drive or Reverse, and more engine movement on take‑off. Visual checks often reveal cracked rubber, sagging gaps, or hydraulic fluid weeping from the mount body.

Is it safe to drive with a worn engine mount?
Short term, the vehicle may still be drivable, but comfort and drivetrain protection suffer. Prolonged use can stress exhaust flex joints, hoses and axles, and may lead to harsher knocks under load. It’s best to book a replacement promptly to avoid knock‑on repairs.
