Freelander v6 cooling

Hi, guys I am new to the freelanders community, just trying to figure out this vehicle, I have a 2006 freelander V6 and it keep pushing out the coolant through the expansion bottle.
I've replace the expansion bottle cap, the complete bottle, I've replace the thermostat, had the radiator remove and professionally cleaned, and just recently replaced the ETC, with all that done it still pushes coolant through the bottle.
I noticed that fans were not switching on before I had the ETC replaced, when the tech unplugd the ETC in the block the fans ran on high speed all the time and no coolant would be pushed through bottle. With the new ECT the cooling fans now switch on at temperature but only low/slow speed and never increase in speed, at low speed coolant still get to hot and pushes it through bottle. Oh and temperature never pass half way mark on gauge.
Is there something we are missing, why fans will not increase in speed?

Oh and sorry for the long read just trying to give as much information as possible.
Thank in advance for the help too guys I've learnt a lot reading through this forum.

Your best bet is to post in the dedicated Freelander section, rather than this section, which isn't for technical issues.

However I suspect you have a failing head gasket, which is very common, if the coolant has dropped too low.
The fan speed is controlled by the engine ECU, so if the engine is between 106°C and 112°C, the fans run on slow speed.

If the head gasket has fail wouldn't that cause the temperature to pass 112°c and read in the temperature gauge got?

No. The temp sender is on the return from the radiator.

So these things have two temperature sensors one in the block and a other where?
I know it's not in the radiator hose because that was removed when the radiator was clean and we didn't see any sensor.
