Coolant hose from thermostat housing to heater hose For Land Rover Coolant Water Hose OE PCH500955G

Product Description:

Radiator Hose

OE NO.: PCH500955G LR115163

Applicable vehicle type: For Land Rover

Automotive coolant hoses (Coolant / Radiator Hose) are the 'blood vessels' of the engine thermal management system, responsible for circulating coolant between components such as the engine, radiator, heater core, and expansion tank, thereby maintaining the engine within its optimal temperature range.

Selection and Failure Prevention

• Temperature Limits: Standard EPDM is sufficient for ordinary passenger vehicles; if the turbine inlet water temperature remains >115°C, silicone or high-temperature EPDM should be prioritized.
• Chemical Compatibility: New-generation OAT/HOAT coolants contain carboxylic acids, which have a slight erosive effect on silicone rubber; 1000-hour immersion testing is required.
• Installation Bending: Bending radius ≥3×OD, avoid twisting; worm gear type stainless steel 304 clamps are recommended, with torque of 2.5~3 N·m.
• Failure Symptoms: Adhesive outer rubber, localized bulging, clamp indentation cracks, cold start leakage powder marks; proactive replacement is recommended at 60,000~80,000 km.

Automotive coolant hoses have evolved from traditional "rubber bent tubes" to modular assemblies that are heat-resistant, chemical-resistant, lightweight, and capable of integrating sensors. A correct understanding of the cost-effectiveness and all-around performance of EPDM, combined with the high-performance advantages of silicone, and matching them with vehicle operating conditions and coolant formulations, can significantly improve the reliability of the engine/battery pack and the overall vehicle lifespan.
