VAICO V20-1307 Radiator Hose

Product Overview

The VAICO V20‑1307 Radiator Hose is a high‑performance cooling system component designed to deliver reliable heat transfer and fluid circulation in automotive engines. Engineered with advanced materials, this hose meets the demanding requirements of modern vehicles while providing exceptional durability and flexibility.

Key Features

• Material Composition: Constructed from premium silicone‑reinforced rubber, the V20‑1307 offers superior resistance to heat, pressure, and chemical degradation. The inner lining is a low‑friction PTFE coating that minimizes wear and extends service life.
• Temperature & Pressure Rating: Capable of operating at temperatures up to 200 °C and pressures up to 10 bar, the hose maintains structural integrity under extreme engine conditions.
• Flexibility & Durability: The silicone matrix provides exceptional bendability, allowing easy routing around complex engine architectures. Simultaneously, it resists kinking and abrasion, ensuring long‑term performance.
• Chemical Resistance: Resistant to coolant additives, antifreeze, and various solvents, the hose prevents corrosion or degradation that could compromise cooling efficiency.
• Leak‑Proof Design: Precision molded fittings and a double‑layer construction reduce the risk of leaks, safeguarding engine temperature control.

Compatibility & Applications

The VAICO V20‑1307 is specifically engineered for use in BMW E60, E61, E63, and E64 models. Its dimensions match OEM specifications, ensuring a seamless fit with the radiator, water pump, heater core, and engine block. Additionally, it can be employed in other vehicles requiring a flexible, high‑temperature hose that meets or exceeds original equipment standards.

Installation Guidelines

1. Preparation: Clean all mating surfaces with isopropyl alcohol to remove oil, dirt, and old gasket material. Inspect the hose for any visible defects before installation.
2. Fitting Placement: Align the hose’s inner diameter with the outlet of the radiator or water pump. Ensure that the hose does not twist or kink during routing.
3. Securing Connections: Use compatible clamps or bolts rated for high temperatures. Tighten to the manufacturer’s torque specifications, typically around 12–15 Nm, to achieve a secure seal without overstressing the hose.
4. Pressure Test: After installation, pressurize the cooling system with distilled water or coolant and check for leaks. Verify that the hose maintains pressure within the specified range.
5. Final Check: Inspect all connections after a short test run to confirm no fluid loss and proper operation of the cooling circuit.

Maintenance & Longevity

The V20‑1307’s robust construction reduces routine maintenance. However, periodic inspections are recommended:

• Check for signs of wear such as cracks, bulging, or discoloration.
• Verify clamp tightness and replace any worn fittings.
• Replace the hose if coolant contamination is detected or if performance issues arise.
