Replacing both mounts together ensures balanced engine support and restores the original vibration-damping characteristics of the drivetrain.
The engine mounts stabilise the engine and isolate vibration from the vehicle body. They maintain the correct engine position during acceleration, braking and cornering, helping ensure smooth power delivery and reducing noise or vibration transmitted to the cabin.
Replacing worn mounts restores drivetrain stability and improves driving comfort.
Function
• Engine Support: Secures the engine to the chassis structure
• Vibration Isolation: Hydraulic mount design absorbs engine vibration and noise
• Drivetrain Stability: Maintains correct engine alignment under load
• Component Protection: Reduces stress on transmission, exhaust and drivetrain components
Over time, engine mounts can deteriorate due to heat, vibration and repeated load cycles. When the hydraulic damping material weakens or leaks, excessive engine movement can occur. This often results in increased cabin vibration, knocking noises during gear changes or visible sagging of drivetrain components.
Replacing the mounts with a matched pair restores proper engine support and ensures smooth, stable operation of the drivetrain.
Replace the engine mount kit if you notice:
• Excessive vibration in the cabin or steering wheel
• Clunking during acceleration or gear changes
• Engine movement when revving the engine
• Visible fluid leakage or cracked mount rubber
