Coolant Pipe

[Rp0thejester]

I need to do a coolant change. Can you show me a diagram of which coolant pipe is lowest so I can do a gravity change please

[MattBLancs]

Mine is a little later (2009) but think likely the same -

I pulled radiator lower hose off.

Note there's also a drain point on the coolant pump (6mm?? Allen grub screw) - it's visible without removing any timing belt covers.

There's a bleed point top of the radiator (big Philips head on plastic plug, quarter turn) I'll check the others tomorrow (heater matrix, can't recall if is one on the block too, normally is)

Here's the diagram

The draining, refill and degassing procedure is the same as the guide here:

This is the official procedure for Draining, Filling & Degassing:

Just ignore the instruction for Euro 6, but otherwise identical.

Is the mentioned Coolant Degassing guide applicable for DS5 2.0 HDI DW10FC 2016?

[GiveMeABreak]

They're generally identical, but follow the Euro 6 part for degassing.
