i believe its under the air intake plenum towards the rear. ;)

it is... Have you had the plenum off recently or done any work down the back (dis pack for example) as you may be lucky and just have dislodged the spade connector.
-
hi,no work done recently but will check connection now i know where it is
-
Could be thermostat stuck open :(
-
ok on closer inspection the needle moves very slightly but not much,even after ticking over for 20 mins,can you tell me where thermotat is and how easy to change...cheers.
-
again, under the plenum at the front in the V of the heads. never had to change one but i believe its not that easy dependant on a certain bolt. ::)

Dont make the same mistake as I made when ordering the new stat as you will need to ask for two new shorter bolts to bolt it down with .... otherwise you will be curseing like I was after all that work u have just done. ::) ;)

true, but 1/2 way through the job when you discover the bolt issue, its a very good idea at the time :y

Before changing things willy-nilly .. how about a simple check ???
Start engine from cold .. leave to idle whilst standing with one hand on the big pipe that goes from the thermostat to the top right (as you face the engine) of the radiator.
One of 2 things will happen ... EITHER the pipe will slowly start to warm up and never get really hot .. OR the pipe will stay cold until a sudden rush of fairly hot water passes through (there is a 3rd possibility but that is linked to overheating so does not apply here..... :) )
If the pipe very slowly heats up .. the thermostat has failed open .. it needs replacing.
If the water stays cold until a sudden surge of fairly hot water .. the thermostat is working .... in which case it is probably an indication problem.
It is, rarely though, possible for the thermostat to work but at too cool a temperature, in this case the "surge" of heat will be mush cooler than "fairly hot" .. if that makes sense .. :)
