Description
Coolant pipes to the heating exchanger for Citroën Peugeot cars with the 2.0 HDI RH02 engine
Part description
This water hose / coolant pipe is intended for the distribution of liquid to the heating exchanger. It is an important part of the cooling and heating circuit, which affects the correct circulation of the coolant and the function of the interior heating. For used original parts, the search by serial number is often decisive, so it is good to pay attention to the designation 6466VE.
The part is especially suitable for mechanics and DIYers who are looking for an original used car part for Citroën and Peugeot cars. By replacing the old hose with a well-preserved original piece, the tightness of the circuit can be restored and coolant leaks can be prevented, which can cause problems with heating and cooling the engine.

Installation recommendations
Generally and typically for this type of part, the exact replacement procedure may vary depending on the specific car model and engine compartment design. It is important to work carefully with the coolant piping to avoid leaks or misalignment of the hose after installation.
1) Before assembly
- Check that the part marking matches the original piece, especially the shape, length, connection diameter and hose routing.
- Inspect the used part for cracks, deformation, abrasions, bulging, or damaged insertion ends.
- Check the condition of the contact surfaces and the places where the hose will be sealed or fixed.
- Compare the location of all bends and any brackets with the old part.
- Work only on a cooled system to avoid the risk of scalding with coolant.
2) Necessary tools and materials
- Basic set of hand tools
- Pliers for hose clips or suitable universal pliers
- Container for catching liquid
- Clean rags or towels
- Work gloves
- Or new clips if the original ones are worn out
3) Step-by-step assembly procedure
- Allow the engine and cooling system to cool down completely and prepare your workspace.
- Secure the vehicle against movement and access the mounting location as necessary.
- Place a container under the place of intervention to catch any leaked coolant.
- Carefully loosen the clips or fasteners of the old pipe.
- Remove the original hose so as not to damage the connection ports or surrounding parts.
- Check the condition of the connection points and clean them of deposits, dirt or remnants of old pollution.
- Compare the old and the new part side by side and verify the match of shape and orientation.
- Place the used hose in the correct position without forcibly twisting or switching the material.
- Sit the hose to the connection sockets fully and position the clips correctly.
- Fix any brackets or lines so that the hose does not come into contact with sharp edges or moving parts.
- Check that the hose is not kinked, twisted or stretched.
- After installation is complete, perform a leak test after commissioning the system.
-
4) Post-assembly checks and test drive / function verification
- After assembly, visually verify that all connections are properly seated and secured.
- Observe for traces of moisture or fluid leakage after the engine warms up.
- Check that the heating system works smoothly and without interruptions.
- After a short test drive, inspect the hose and surrounding connections again.
- After the car cools down, check for additional leaks.
5) The most common assembly mistakes + how to avoid them
- Exchanging a part for a similar part – always compare the shape and code of the product with the old part.
- Insufficient seating of the hose – the hose must be fitted evenly and without misalignment.
- Using damaged clips – worn fasteners can cause leaks.
- Mounting on dirty connection points – dirt often leads to small leaks.
- Twisting or kinking of the hose – always check the natural routing of the part after assembly.
- Underestimation of follow-up inspection – after warming up the system, it is advisable to check the connection again.
Reasons why the part is damaged
- Aging of the material – rubber and plastic parts harden, become brittle and lose elasticity over time.
- Thermal stress – repeated heating and cooling accelerates hose wear.
- Pressure stress in the cooling circuit – long-term stress can lead to cracks or leaks.
- Mechanical abrasion – contact with surrounding parts or inappropriate hose routing causes surface damage.
- Damaged or weak clips – insufficient fastening can lead to leakage and subsequent deterioration of the part.
- Improper pre-assembly – switching, twisting or force fitting shortens the life of the hose.
