NISSAN 21508-4P000 Radiator Mounting Rubber Bushing

This genuine Nissan radiator mounting rubber bushing (part number: 21508-4P000) is a precision-engineered vibration-damping mounting element responsible for the stable and secure mounting of the vehicle's cooling system. Genuine OEM quality guarantees a precise fit and long service life even under the extreme conditions of the engine bay.

Key Functions and Features:

• Vibration Damping: Absorbs vibrations caused by engine operation and road irregularities, protecting the radiator from mechanical stress and cracking.
• Premium Material Quality: Made from a specialized heat- and oil-resistant elastomer that withstands the high temperatures and environmental influences present in the engine compartment.
• Stability: Prevents radiator displacement, ensuring stress-free routing and placement of connecting hoses and electrical wiring.

Technical Specifications:

• Manufacturer: NISSAN (Genuine OEM)
• Part Number: 21508-4P000
• Product Type: Radiator Mounting Rubber Bushing (Mounting)
• Material: High-density vulcanized rubber

Common Symptoms of Wear:

Radiator mounting bushings undergo natural aging due to constant thermal stress. The most common signs of failure include:

• Softening, cracking, or complete embrittlement (hardening) of the rubber material.
• Visible play or instability of the radiator during manual inspection.
• Rattling or knocking noises originating from the engine compartment when driving on uneven road surfaces.

Replacing damaged or deteriorated mounting bushings is essential to prevent premature radiator failure (leaks, cracking).
