Description
Engine mount, silentblock for 1.8 16V and 2.0 16V engines for Citroën C4, C4 Picasso, C5 II, C5 III and Peugeot 307, 407, 508. Right engine support.
Product Overview
This right-hand engine mount (silentblock) is designed for 1.8 16V and 2.0 16V petrol engines used in a range of Citroën and Peugeot models. It secures the engine to the body/chassis while damping vibrations and absorbing engine torque. Part number 184699 is commonly searched by mechanics and DIY enthusiasts when replacing worn or damaged mounts on these models.
Applications
- Citroën C4 (1.8 16V)
- Citroën C4 Picasso (1.8 16V)
- Citroën C5 II (1.8 16V / 2.0 16V)
- Citroën C5 III (1.8 16V / 2.0 16V)
- Peugeot 307 (1.8 16V / 2.0 16V)
- Peugeot 407 (1.8 16V / 2.0 16V)
- Peugeot 508 (1.8 16V / 2.0 16V)
Function And Benefits
The mount isolates engine vibrations from the cabin, maintains correct engine alignment, and limits excessive movement under acceleration or during gear changes. Replacing a worn mount restores driving comfort, reduces noise and vibration, and prevents secondary damage to hoses, pipes and other engine supports.
Most Common Cause Of Failure
Engine mounts fail primarily due to rubber deterioration from heat, age and oil contamination, as well as mechanical fatigue from repeated engine torque and road impacts. Typical symptoms include increased vibration in the cabin, clunking or knocking during acceleration or gear changes, visible cracks in the rubber, and noticeable engine movement when revving. Failure may accelerate if oil leaks from nearby engine seals contact the mount.
Installation Recommendations
Replacement should be performed with the vehicle safely supported on lifts or stands. Support the engine with a jack and a block of wood beneath the oil pan or an engine support bar to avoid damage. Remove mounting bolts, replace the old mount with the new unit (ensure correct orientation for the right-hand side), and tighten bolts to the manufacturer’s torque specifications. After installation, check related mounts and engine attachments for wear. If uncertain, have the job completed or checked by a trained technician; improper installation can lead to premature failure or engine misalignment.

Practical Notes
Engine mounts generally last many years but lifespan varies with driving style and conditions; a common replacement interval is around 80,000–150,000 km depending on usage. Always inspect for oil contamination and check adjacent components (engine brackets, transmissions mounts, exhaust supports) during replacement. Using the correct side (right) and the exact part number 184699 ensures proper fit and performance.
