I have a 2013 Knaus Sky TI on a Ducato 2.3lt 130 multijet and having bought five litres of Paraflu UP and five litres of demineralised water so would love to attempt a coolant change myself.
Having removed all the screws from the Knaus designed full front grill but am thwarted by what looks to be six fragile looking plastic lugs held in with steel clips, none of which look strong enough to yank!
So I asked a friend who told me to part the radiator bottom hose to drain down the radiator, problem is I cannot identify it amongst all the other pipes!
I even started taking off the bottom intercooler pipe, I found out later!
Can anyone please guide me to the correct pipe? ;)

Mine is a 3 litre, but radiator may be similar. Looking from front, right hand side of radiator, low down at rear is the coolant pipe. It has a clip you squeeze in from either side to release the fitting from radiator.
I found i could only squeeze the clip by lying under van and putting left arm up to side of radiator and squeezing clip from above, leaving right hand to wiggle and pull fitting off.
This method ensures you are undervan when coolant decends on you!
There is a bleed valve on pipes to heater matrix, engine side of bulkhead, high up.

Don't forget antifreeze is not nice stuff - please don't dump it on the road or down a drain.

It should be recycled properly. (y)

Thank you so much, I think I've seen that pipe whilst rolling around under the front of the van!

If you do remove the bottom rad pipe have an assistant look in the expansion bottle with the cap removed as you squeeze the pipe firmly.
It it has water in the expansion bottle level will rise and fall slightly.
No movement and it ain't a rad pipe.

Wow, that's a real good idea, I'll get some help to try that.
Thank you

There's one thing....
Removing the intercooler hose when your looking for a rad hose isn't as messy as removing a rad hose when your looking for an intercooler hose. :ROFLMAO:
