• Compatibility: Specifically designed for the BMW 7 Series cooling system but also compatible with other luxury vehicles requiring a high‑quality silicone hose.
• Installation Type: Features quick‑connect fittings on both ends, allowing for rapid replacement without the need for additional tools or adapters.

Why Choose VAICO V20-1690?

The VAICO V20-1690 Engine Cooling Hose stands out due to its combination of durability, ease of installation, and proven performance in demanding automotive environments. Its silicone construction resists cracking, blistering, and chemical attack from antifreeze solutions, ensuring a reliable seal over the vehicle’s lifespan.

Installation Guide

1. Preparation: Turn off the engine and allow it to cool completely. Drain any remaining coolant if necessary to avoid spills during replacement.
2. Remove Old Hose: Carefully detach the existing hose from both radiator and water pump connections, noting the orientation of any directional fittings.
3. Attach New Hose: Slide the VAICO V20-1690 onto the radiator outlet first, ensuring a snug fit. Then connect the other end to the water pump or engine block inlet.
4. Secure Connections: Tighten all fittings with a torque wrench set to the manufacturer’s recommended specification (typically 12–15 Nm). Use thread‑locking fluid if required by your vehicle’s service manual.
5. Refill Coolant: Reinstall the coolant reservoir cap and refill with the appropriate antifreeze mixture. Bleed the cooling system to remove trapped air pockets.
6. Check for Leaks: Start the engine, let it reach operating temperature, and inspect all connections for any signs of leakage or pressure loss.

Maintenance & Longevity Tips

• Regularly inspect hose ends for wear or swelling; replace if any deformation is observed.
• Avoid exposing the hose to direct sunlight for prolonged periods, as UV radiation can degrade silicone over time.
• Use only manufacturer‑approved coolant formulations to prevent chemical incompatibility that could compromise hose integrity.
