 Citroen C4 - Plumbing Techniques - Redviper
Hi All

While I was topping up screen wash and checking levels of SWMBO’s Citroen C4, I had a bit of a poke around just having a look at what’s what under there.
It’s the VTR+ with the 1.6 HDI 110ps engine.
I notice that there are two radiators, as you are looking towards rear of the engine bay (the radiators closest to you) the one on the left is smaller and (IIRC) there is a fat pipe coming from the top of said radiator into a black box with some electric cables bolted on top of the engine.

I initially though that it was a cooler for a turbo, but as far as I’m aware this engine is naturally aspirated, there is no turbo.

Could anyone enlighten me as to what it is, and what its for? I would really appreciate it.
It’s a great engine (I think so) as there is a lot of power for such a small engine – its very refined as well.
Many Thanks
