Installation Guidelines

1. Preparation: Ensure the engine is cool before beginning work. Drain the coolant system to prevent spills or burns.
2. Removal of Old Hose: Carefully detach the existing hose from both the radiator and water pump connections, noting any fittings or adapters used.
3. Inspection: Check the new V20-1239 hose for any visible defects such as cracks or bulges. Verify that the length matches the required span between components.
4. Connection: Attach the hose to the radiator outlet and water pump inlet using appropriate clamps or fittings. Tighten securely but avoid overtightening, which could damage the rubber core.
5. Pressure Test: Refill the cooling system with fresh coolant and perform a pressure test to confirm there are no leaks. The hose should maintain pressure without any drop over a short period.
6. Final Check: Start the engine and monitor for proper temperature regulation. Inspect all connections after a brief warm‑up cycle to ensure stability.

Maintenance Tips

• Regularly inspect hose fittings for corrosion or loosening, especially in vehicles exposed to road salt or harsh climates.
• Replace the hose if you notice any signs of wear such as soft spots, cracks, or bulging sections.
• Use a compatible coolant that meets manufacturer specifications to avoid chemical incompatibility with the hose material.
• When cleaning the radiator or water pump, avoid using harsh chemicals that could degrade the rubber core.
