Part description

This water hose to the radiator is designed for 1.5 HDI engines and serves to safely guide the coolant in the cooling circuit. A properly sealing hose is key to a stable engine operating temperature, proper operation of the radiator and heater, and prevention of fluid leakage.

The part is a suitable choice when repairing leaks, replacing a damaged hose or when servicing a cooling system where it is necessary to quickly and reliably replace the original line.

Installation recommendations

• Before assembly, check the condition of the radiator neck and other connections (cracks, corrosion, burrs) so that the hose fits and seals properly.
• It is recommended to use matching buckles in good condition; tired clips often cause re-leakage.
• After topping up the coolant, perform a ventilation of the cooling system according to the normal procedure for the given car and check for leaks after the engine has warmed up.
• After the test drive, recheck the coolant level and any signs of leakage.

Reasons why the part is damaged

• Aging of the material due to heat and pressure in the cooling circuit (hardening, microcracks).
• Leaking or deformed clips which gradually damage the hose or fail to tighten the joint.
• Contact with oil/chemicals or unsuitable coolant that accelerates rubber/plastic degradation.
• Mechanical damage (abrasion against surrounding parts, bad hose routing, vibrations).
• Engine overheating and pressure surges in the system that increase the risk of cracking or tearing.
