Then yesterday I change water pump with new one (need to say that old one was in excellent condition ((...) So, can anyone give me any idea, what could it be, or how can I check whats wrong in system? May be is faulty t sensor?Xantia engine overheating?

Xantia engine overheating?
Hi to all! There is happened strange thing with my Xantia 1.8 8v cooling system. At first any weeks ago temp. indicator began to show 95-100 degree insted normally 90 when ride 100-120 km/h...Ok. First thing what I did, was that I change thermostat and coolant liquid (old one was really like white coffee!!!). That action didn`t help Then yesterday I change water pump with new one (need to say that old one was in excellent condition ((...) So, can anyone give me any idea, what could it be, or how can I check whats wrong in system? May be is faulty t sensor?

Temperature problems on the Xantia are usually caused by the electric cooling fans not spinning when they are supposed to, but at 100 km/h the fans aren’t needed or used anyway.
First ensure that there’s no air trapped in the system, by opening the vents on the heater hose and thermostat housing when the engine is running.
Since the coolant was brown, I think that the inside of the cooling system must be very dirty,
and needs a good flush.
The bottom part of the radiator may be full of sediment.
Maybe try to flush the radiator, carefully, because I think the sides are plastic.
Also check that there’s plenty of oil in the sump, because the oil helps the cooling.

I noticed that also. Could be oil emulsion (+rust stain) and with the other symptoms might indicate imminent head gasket failure perhaps ? This is similar to what happened to me with a BX.jgra1 wrote:Cloggz... the 'white coffee' is a tiny bit worrying?

The PSA engines type XU have a very exclusive feature : they would always show a blown headgasket as an over-pressurised cooling system - thus expelling the coolant.
VERY rarely they show the old school indications of grey oil (water in oil) - or oil in the coolant.
Its important to know :
A blown headgasket will not by itself cause the engine to everheat. Something else is at fault - causing the overheating - which at some point has caused the HG to fail. Not vice-versa.
Please do a thorough faultfinding and overall engine service - BEFORE you decide to rip the head. Remember : its your wallet !

Sounds to me much like a blocked radiator. Over about 20 MPH the fans make no difference as the draught from the car's motion is greater than the fans can possibly produce - so if its happening in normal driving - forget the fans.
The radiator is a crossflow type - with its tanks at either end. Old fashioned ones had the tanks top and bottom and any sludge would collect relatively harmlessly in the bottom tank. With a crossflow radiator it starts blocking the tubes from the bottom and is unnoticed until it blocks one tube too many and then the car overheats. It may be that you can feel that the bottom part of the radiator is cold while the top is hot.
You may be able to shift the sludge by flushing - and you may not - in which case you'll need a new radiator.

If its still got the original radiator then like previously suggested it could well do with a new one, and for less that £100 its a sure thing to have done.
The xantia when i got it, the temperature read more than 90oC continuously, a new radiator brought that temperature down to 70oC and never anymore while driving.
Money well spent.

At first I noticed, that my new thermostat opening temperature marked on was 88 degree, but on the old one 83 degree by Celsius! And second thing, as mentioned Jeremy is that "bottom part of the radiator is cold, while the top is hot"
Now I`ll try to flush my radiator...
