Each unit undergoes 100% quality inspection before packaging. Manufacturing conforms to OEM specification standards for cooling system hose applications.
SAFETY WARNING: Allow engine to cool completely before removing radiator cap or cooling system components. Pressurized hot coolant can cause severe burns.
Installation Guidelines:
- Drain coolant completely from radiator
- Remove old hose by loosening clamps and twisting to break seal
- Clean mating surfaces and inspect for corrosion or debris
- Install new upper radiator inlet hose, ensuring proper routing
- Secure clamps to specification (do not over-tighten)
- Refill with manufacturer-recommended coolant mixture
- Bleed cooling system and pressure test for leaks
Maintenance Schedule:
- Inspect upper radiator hose every 40,000-50,000 km or annually
- Replace immediately if showing cracks, swelling, hardening, or leaks
- Replace coolant every 2 years or 50,000 km
- Inspect all cooling system hoses when replacing one component
