NISSAN 21307-VC200 Water Hose

This genuine NISSAN water hose (OEM part number: 21307-VC200) is an essential component of the vehicle's cooling system. Its function is to safely transport coolant in a closed system between the engine block, radiator, and heating system, ensuring optimal engine operating temperature and preventing overheating.

Technical Features and Material Construction:

• Premium Base Material: Made from high-grade EPDM rubber compound resistant to heat and electrochemical degradation, ensuring a long service life even under extreme temperature conditions.
• Fiber-Reinforced Construction: Internal synthetic fabric or polyester fiber reinforcement guarantees high tensile strength and withstands operating pressure within the cooling system without expanding.
• Chemical Resistance: Resistant to antifreeze coolants, anti-corrosion additives, and engine bay oil vapors.
• Precise Fitment: As a genuine OEM component, it features an exact geometric shape, allowing for stress-free and leak-free installation with factory retaining clamps.

Common Symptoms of Water Hose Failure:

• Visible Cracks: Over time and under thermal stress, the rubber loses elasticity, and micro-cracks appear on its surface.
• Material Hardening or Softening: Overheating can make the hose brittle, while oil contamination can soften it, leading to structural weakening.
• Coolant Leakage: Wet spots on the hose surface or at connection points, resulting in a drop in coolant level.
• Temperature Rise: Loss of system pressure or fluid loss due to leaks can cause the engine to overheat.

To ensure reliable cooling system operation, regular inspection of the water hoses is recommended, along with immediate replacement using a genuine OEM part if any damage, cracks, or leaks are detected.
