Xantia HDI

Post by redfrus » 01 Mar 2005, 18:32

Can anyone tell me what the pump inside the nearside wheel arch does. There is a small exhaust pipe and two heater pipes on this unit.When you stop the engine this unit continues to run for a minute slows down then stops.It sometimes steams from the pipe under the front bumper.The model is a 1999 exclusive.

It's an auxiliary heater. The HDi engine is so efficient it can take an age to warm the coolant up on cold days, so extra heaters were fitted to some cars.

When the outside temperature is above, say, 7C, then it doesn't seem to run. Well, mine doesn't, anyway. It seems to have been fitted just to the Exclusive. Somewhere on this forum is a thread (Title is something like "what's this?" with a piccy that someone took with the wheelarch liner off.
