Water hose connection to expansion tank for 1.5 HDI CITROEN PEUGEOT OPEL FIAT TOYOTA
Part description
This water hose / connection to the expansion tank is designed for 1.5 HDI engines and serves to safely guide the coolant in the cooling system. Proper hose function is key to maintaining engine operating temperature, circuit tightness, and stable cooling system pressure.
The part is suitable as a replacement in case of damage to the original hose, leakage or rupture of the material. Thanks to the search number 9812439880, you can easily find it even by the markings from the original part.

Installation recommendations
- Before assembly, check the condition of the neck of the expansion tank, connections and clamps – leaks often occur outside the hose itself.
- It is recommended to use new clips or verify the full functionality of the existing ones (correct diameter, sufficient pressure).
- After replacement, top up the coolant to the correct level and bleed the system according to the procedure for the vehicle in question.
- After warming up the engine, check that there are no fluid leaks anywhere and that the pressure in the system is maintained.
Reasons why the part is damaged
- Aging of the material due to heat and pressure in the cooling system (hardening, cracking).
- Leakage at joint due to loose/inappropriate clip or deformed neck.
- Overpressure in the system (e.g. with a problem with the cap of the expansion tank or venting) leading to a burst.
- Mechanical damage during service interventions or contact with surrounding parts.
- Inappropriate coolant or neglected replacement which accelerates the degradation of rubber/plastic parts.
