leaking sphere seal

Post by froggy »

HI, My Xantia 1.9 Td, has a slight leak coming from the seal on one of the spheres. The seal is located at the front , right by the radiator. my question is ; is it worth removing the sphere, cleaning the seal or replace with new ? cheers Terry.

The seals should ALWAYS be replaced when fitting new spheres - so should always be replaced if removing the sphere as the seal will likely be deformed and may not 'mate' properly.

Part no. is 5272 15 (square seal).
Have seen a few unbranded spheres fitted with round-section O-rings, which will not be self-sealing.

It sounds like your leak is at the main accumulator, attached to the pressure regulator. Be aware that the pressure regulator itself can leak, usually from the O-ring at the other end of the body, so clean it up and check for the actual location of the leak before doing anything else.

...and the low pressure return pipe from the regulator.
