Expansion Tank Removal

Hi there!

I need to deep clean my coolant expansion tank/bottle. I removed the norma clips but I can't get the tank out. Is there any guide or walk-through (can't find) one to get the little devil out? Thanks

Hi pedroaniceto, there is no guide because it is not a difficult or complicated job to remove.

After the system has cooled, drain down the cooling system into a container.
Disconnect all the plastic pipes and the level sensor cable connection.
The expansion tank is attached to the car by its plastic mounting lugs, release the lugs and as they are released, lift out the tank.


If you are interested in these jobs on a C3, I highly recommend the Haynes manual for the C3
