Fixed thanks guys it was a small blockage in the return pipe and the temp sensor was knackered :D

Could it be head gasket gone and pressuring coolant system?

Go get a compression test done see if its down on 1 or more cylinders

i was thinking same thing but there is no oil in water and no water in the oil also no white smoke from exhaust!

No m8 they all worked fine before so i thought they would still be ok!

Hi guys ive just fully rebuild my g60 after it blew a piston now the bloody temprature gauge warning light is flashing 30secs after start up and stays on then the gauge goes up slowly to 100c fan has been bypassed onto manuel switch which i turn on to cool at 100c but then it doesnt go down it just stays at 100c ,Heater in car is blowing cold only goes warm when engine is reved at around 3000rpm. Ive replaced thermostat & water pump only thing i can think of its the coolant temprature switch, which switch is it the blue,or the black or both and if any of you guys have any ideas what could be causing this it would be greatly appreciated!

Thanks Shaun :?
