I'm told that yes that is where it is and Yes it IS a pig.

Why are you considering changing it? I ask because my temp water temp gauge is always very low and I thought that may help?

On the 2.0 it is next door to the water pump in a housing.......

1 remove the pas belt for access
2 remove the pas pump mount (don't undo any haoses)
3 remove hose from coolant pump housing
4 remove 2 bolts from thermostat housing and remove housing
5 take stat out (make sure you use a new rubber ring gasket)

fitting is a reversal off removing..oh and also empty the coolant before anything alse as there's a fair bit of water there

and robster does your car get warm (i.e heater) as this could be the temp sensor at fault

Hey Boney,

No, the gauge shows in the coldest 3 bars at all times unless i'm stationary for a period of time then it goes to half way. I should have thought it should sit just below half way all the time?

Thanks Mate,

Rob

robster i had a similar problem with my old golf...and that turned out to be the temp sensor.....

If she is blowing hot air from your heater when it show's cold I would try that first

Ok mate thanks. The MFA shows an appropriate oil temp while the coolant gauge is set at cold so i'll give it a look. Looks like ECP will be getting lots of my money this month!
