I need to drain the water from the radiator because it is a rusty colour and my temperature warning light keeps coming on,eventhough there is
enough water in the tank!
I also need to know how to change the auxiliary belt?

Please help I am a new member!!

Welcome to the forum John.

The radiator should have a drain plug on the bottom on the right hand side as you look at it from the front. You may need to remove the radiator cover to see it. Either way, I think you'd be better off flushing the entire system if the coolant is looking rusty. Bear in mind it may look rusty anyway as in my previous HDi at least, orange antifreeze is used.

After draining the radiator, pop off the top and bottom hoses and run water from a hose first through the radiator until it emerges clean from the bottom radiator outlet, then insert water hose into the top hose and flush the engine through until it comes out the bottom hose. Be gentle with the radiator pipes as the fittings can be fragile.

The aux belt is relatively simple. After removing the radiator cover, remove the ECU from its box and unscrew the box from the wing. Now you should be able to see the aux belt auto tensioner. 15mm spanner on the bolt and rotate it anti clockwise, have a suitable long reach allen key to pop through the hole in the assembly. Hopefully, you'll see what I mean when you go to do it. There is a hole that rotates with the assembly and this needs to line up with the hole in the backplate. Hopefully someone may be able to post the diagram from the Haynes manual.

Slip the belt off. If fitting a new belt, loosen the manual tensioner bolt. This is in the middle of the crank pulley, auto tensioner and air con pulley. Fit the belt and then tighten the manual tensioner until you can take the allen key out of the auto tensioner easily.

If re using the old belt, just release the auto tensioner with the spanner and remove the allen key, then gently let the tensioner take the slack.

Why may I ask do you wish to change the belt? Also, when the temp warning light comes on, is the needle in the red zone?

Last but not least, where are you located? If local I could help with the aux belt. Hope that helps and you can follow my explaination well enough.

Sorry to jump in on this thread, but it's prett ymuch exactly the spot I find myself in. I'm tring to reassemble things after the failure of my crank pulley (note to everyone else - if it rattles, don't ignore it for months!!!)

I do not know the routing of the belt, though an educated guess would be (in the power direction):

Crank - AC - Lower Idler - alt - upper idler - pump - crank

From your description above, rotating the upper idler anticlock (towards the rear of the car) would tighten the belt.

Any change of that diagram?

I could not get the thing to budge either, what locks it in place?

I recently changed my aux belt,hopefully this could help you both:

Monkey,
I'm not sure you've got the belt routing right. I'm looking at my Haynes now,the pic I used to route mine,(Cit Xantia '93 - 2001,K to Y reg,maroon book - Page 1B .14 every 12000 miles diesel models - Fig 15.35. Says 2.1 engine but it's same route as mine..)
but I can't copy it..

Crank - AC - Alt - bottom,manual tensioner - Hydraulic pump - under the top tensioner and back to the Crankshaft pulley. Please correct me if I'm wrong anyone.

This is the way I did it,not the 'technical' way,but it worked for me. I also didn't need to remove the ecu etc, although that is an excellent way of doing it, as there's less space near the top tensioner to get a spanner on than a gnats private hair...

Few pics as well, hope it's of some help:

The Temp Warning light will also come on if theres any fault in the Cooling Fan circuit!

Ive had this on a 2.o HDi Xantia and it turned out after a Lexia session to be one of the 3 relays that sit between the fans behind the triangular cover!

Id strongly reccomend looking behind here and removing each relay to see if theres any burnt out legs on the relays....!

Thanks to all who replied to my query, but in the end I took the car to a citroen specialist, who charged me £50 for larbour and parts.

Nice one! Cheers for that - the routing is correct but mine has a different flavour tensioner, much closer to the pump than the crank pulley. Some enterprising use of a 15mm spanner, two pry bars and a block of wood held it out the way for me while I put the belt on. All is well and the beast's back on the road once more (although I don't half need some front tyres...)
