2001 Rover 45 temperature gauge gone mad

Car: Rover 45
Year: 2001
Variant: 1.8 manual

Categories: Running Rough, Starting & Power Loss

Dec 23rd I lost alot of water through rat bitten rad.hoses(incl.main top hose) had replaced and since then for the 1st time since Ive had the car, the temp gauge starts to rise after about 1 mile, if heater and fan switched on, drops and stays on normal. Some times waggles up/down when overtaking cyclist and pulling back in, or changing direction(ie turn left or right). sometimes the cooling fan kicks in when cold starting.
Garage issaying this is normal - I do not think so!!!!is there a sensor which controls gauge/thermostat, is the thermostat upset- airlock supposed to have been removed. If this was head hasket surely there would be oil in water res. or water on dipstick - can someone help?

Block test would let you know if any gasses in cooling system relating to gasket issue ,that steel seal seem,s to work in some cases.

Fan should not kick in on cold start .Could check / replace engine coolant temp sensor .You could have a head gasket fault without it mixing with the oil , it could be blowing out the ex. tailpipe .Depends where gasket blown .Check coolant level is not dropping and if still having problems get a block test carried out as suggested .
