I have not had to do this, but I do know the one you are talking about.

I would remove the air filter box as if you were trying to get to the EGR valve as in this topic
diesel-c3-tips/citroen-c3-1-4-16v-hdi-e ... -t289.html

And take it from there to remove and replace. You may find singe use hose clips so you will need to cut these off and replace them with some stainless steel hose clamps (amazon) if they don't come with the hose.

This is a picture of the 8v engine out of the car and a good view of the hose that you wouldn't usually get to see.

Which may be helpful?



When refilling, you can follow these tips on this topic
citroen-c3-tips/citroen-c3-coolant-t40.html

And only refill the system with the correct OAT coolant (here).


If you manage to take any pictures of the job, they would be very welcome on the forum :)

The Haynes manual for the C3 (amazon here) is a good read for these sorts of jobs if you need more than the image and posts above.

Funny old world isn't it - I've just this morning replaced this double hose myself.
It's relatively easy to do the job, even if at first glance it seems impossibly complex and too difficult to get the new hose in.
Firstly, get the car up on ramps before you start, as you will have to work underneath in order to reach the lower end of the hose that's behind the water pump.
Next remove the engine air cleaner and its assembly. - it's quite difficult to weedle the lower half of the assembly over the engine but it can be done with persistence.
Then remove the fuel filter and the air intake hose that runs below it.
This should give you basic access to the hose assemblys path, with its passage below the gas cooler being the most difficult place to get it out of. In my case I pulled the hoses out of their clips whilst my brother, who was underneath the car, reached up and pulled the clip holder down very firmly in order to let the hoses pass the clips.
One warning - if you've never done it before, pulling out the engine drain plug unleashes a flood of coolant that splashes everywhere, including all over you if you're underneath (which is the only way of reaching the plug as far as I can see).
Presumably you've invested in the Haynes manual?

Another thing - get some Jubilee clips to replace those bloody awful clips that Citroen put on hoses. They are the devils own business to get off in confined spaces, unless you've got the remote tool that garages use to put them on and off. There was much effing and jeffing when my brother tried to remove the lower ones behind the water pump, and it seemed to take up a large part of the time involved in changing the hoses!

yes, if they look ok, re-use them. Its the drain plug.

You should inspect the o-ring and change that if its worn, cracked, damaged or missing :o

Interesting that your purchase of the multi hose didn't include the drain plug ( parts 4 to 6 in the diagram above) - the one I bought from GSF included them, which was very useful as the original o-ring had deteriorated badly, expanding so much that it was impossible to replace the plug once it had been removed.
