• Diameter: 20 mm nominal internal diameter, suitable for most standard radiator fittings.
• Length: 1358 mm (1.358 m) – a versatile length that accommodates a wide range of vehicle chassis layouts.
• Pressure Rating: Up to 10 bar (145 psi), allowing safe operation under high‑pressure cooling systems.
• Temperature Range: -40 °C to +120 °C, ensuring performance in both cold climates and hot engine environments.
• Color Coding: Standard black with a distinctive VAICO logo for easy identification during maintenance.

Design Features & Benefits

The V20-1358 incorporates several design elements that enhance its functionality and ease of use:

• Dual‑Layer Construction: The inner TPE layer provides excellent flexibility and resistance to coolant chemicals, while the outer HDPE layer protects against abrasion and UV exposure.
• Pre‑Tensioned Fit: Engineered with a slight pre‑tension that reduces the risk of kinks or leaks during installation.
• Quick‑Release Fittings Compatibility: Designed to mate seamlessly with standard quick‑release clamps, enabling rapid replacement without specialized tools.
• Corrosion Resistance: The materials resist rust and corrosion even when exposed to acidic coolants or high humidity environments.
• Extended Lifespan: Tested for durability over extended periods, the hose maintains its integrity under repeated thermal cycling.

Installation Guidelines

Proper installation is critical to ensure optimal performance and prevent leaks. Follow these steps for a flawless fit:

1. Preparation: Drain the cooling system completely and allow it to cool before handling the hose.
2. Inspection: Verify that both ends of the hose are free from damage or manufacturing defects. Check for any visible cracks, bulges, or irregularities.
3. Alignment: Align the hose with the radiator and engine block fittings, ensuring that the inner diameter matches the outlet size precisely.
4. Securing: Use high‑quality clamps or quick‑release fittings. Tighten to the manufacturer’s torque specifications (typically 10–12 Nm) to avoid over‑tightening, which can damage the hose.
5. Leak Testing: Refill the cooling system with fresh coolant and perform a pressure test at 1.5× operating pressure for 30 minutes. Inspect all connections for leaks.

Maintenance & Troubleshooting

While the V20-1358 is engineered for longevity, routine checks can preempt potential issues:

• Visual Inspection: Periodically examine the hose for signs of wear such as cracks, hardening, or bulging. Replace immediately if any damage is observed.
• Coolant Quality: Use a coolant that meets the vehicle manufacturer’s specifications to avoid chemical degradation of the hose material.
• Temperature Monitoring: Keep an eye on engine temperature gauges; overheating may indicate insufficient cooling capacity, possibly due to a compromised hose.
• Pressure Checks: Verify system pressure regularly. A drop in pressure can signal a leak or blockage within the hose.

Compatibility & Applications

The V20-1358 is designed to fit a broad spectrum of vehicles, including:

• Passenger cars with standard radiator and engine block configurations.
• Light commercial vehicles where robust cooling is essential.
• High‑performance models that demand reliable heat dissipation under elevated operating temperatures.

Its universal sizing and pressure tolerance make it a preferred choice for mechanics and automotive enthusiasts seeking a dependable replacement or upgrade to aging radiator hoses.
