Default Temperature problem...

I have some problems with the temperature om my 306 1.6
When driving with low revs the temperature is "normal" 90. But when driving on motorways or with higher revs the temperature rises to around 95-110c. If i slow down, the temperature slowly decreases.
When standing still the temperature also rises to around 100-110c

I have changed the radiator, thermostat, temperature sensor (gauge) and cooling fluid. But that did not work.

-The water on top of the radiator is hotter than the bottom.
-I have a steady flow of hot air from the vents.
-When undoing the bleeding screw on the hose to the bulk head, i get a stream of water which strength follows the revs. (Rules out water pump?)

Any ideas?

How old is the battery and what condition are the earth points and electrical connections on the temperature sensor?

The battery is only 1 year old and in good condition.
The earth points looks ok.
If there was a earth problem, shouldn't it give other symptoms as well?

Not always. On my 1.4 petrol 306 a bad earth made the STOP light flash on screen.

On my 2L diesel 306 the brake warning light stayed on for 5 seconds after starting.

On my 307 it made the power steering heavy.

Is it possible that the gauge could be the problem?

Possible. Planet should be able to test it.

I have now found out that one of my fans are dead.
So i have gotten hold of a complete set (both fans in frame with relays)

How big is the job of changing the whole thing?

Update
I have new earth cabels, and gone over the connections to the gearbox and chassis

I have now got both fans running.
When i unplugg the brown coolant fan sensor both fans starts at low speed for a few seconds, then high speed.

According to this workshop Cooling Fan when the engine is running, the low speed should kick in at 97 and the high speed at 107. But my fans does not kick inn on low speed before the gauge shows close to 110.

What could then be wrong? Could it be related to the cooling fan control unit in the wheel arch?

Update!

Her is an update on my problem. I could really need som inputs, since i am stuck...

The problem:
-The temperature gets to hot. 100-110c

-Driving up a hill makes the temp rise and goes slightly into the red, costing down the other side makes ti go a little bit down again

-Unplugging the fan coolant sensor so both fans operate at full speed does not help
-If i open the bleeding screw on the hose to the bulk head i get a steady stream of water that follows the revs. (Rules out waterpump???)
-I get a steady flow of hot air from the heater.
-I do not lose any coolant

The low speed fan that should kick in at 97c does not kick in before temp gauge shows appr. 105-107c
High speed fan should kick in at 107,c but it does not engage.

What i have done:

-Changed thermostat=no difference
-Changed radiator + coolant= no difference
-Changed temp sender to gauge and temp sender to fan ECU= no diffence
-New earth cable from gearbox and battery= no difference
-Cleaned cable connection the the fans=no difference
-Tried another (used) fan controll unit ECU (Bitron) = no difference

I im stuck with this problem, so if anyone have any ideas on what could be wrong let me know :-)

I found i nice guide on another forum that i used to controll the signals to and from the Bitron unit.
In my case everything works fine, so bad wires to and from the Bitron unit can be ruled out.


Unplugg the Bitron unit and you will se that all the pins on the connector is numbered.


Earth pin 1= both fans on slow speed
Pin 4 = permanent 12v
Pin 15 = switched 12v
Ignition to ACC and earth pin 10 and 1 = both fans on high speed
Resistance pin 7 and 14 = cold engine around 1,9ohm. Hot engine around 3,5 ohm (confirms good temp sensor also)
