C4 HDI coolant expansion pipe

Post by Med_tech3 »

Hi

My coolant expansion pipe (the very thin rigid plastic pipe with two click lock connectors that go into the radiator and the coolant expansion tank) is leaking at the radiator end. Unfortunately it is not the O ring as the coolant is squirting out where the pipe meets the connector.
I have looked for a replacement pipe but I am not having any luck.
Is the bore of the pipe vital or can I replace the pipe with a larger rubber coolant hose and fix it with jubilee clips?
If I do need the correct hose can you suggest where to obtain one from?

Thank you
Simon

Hi Simon
Is it the hose shown at item 7 in the diagram you want?

If so, this is part number 1323Y4. It is available from Citroen to order and is priced at: £11.11 including VAT. So not as expensive as you may have thought. :-D

Just give your local Peugeot or Citroen dealer a call and quote the part number that I specified above. They will order it in for you for collection.

Yes that is the part. Thank you so much! I looked on ebay and other car part places but they wanted £20+

The bay of evil and other such places sell a lot of overpriced tat - even sellers that do sell the genuine original parts don't check the current prices before listing the item. The parts from Citroen directly can often be cheaper as you have just discovered. :-D
