Had loads of stuff changed the last two days, coolant flush and thermostat (along with cambelt/tensioners/waterpump/aux belt/fuel filter) was done.

Warmed up within a few miles tonight on way home from garage... old thermostat had 2 holes drilled in it? Weird? Why would someone do that? Haha..

Hopefully I'll have no trouble after all this work has been done and my mpg will go up, did get nice and toasty real quickly (compared to how it was) which will be a bonus for winter mornings :)

Got my thermostat ready to fit at the weekend. I have had to buy a new battery too... Seems my car has taken to this winter quite hard! Only doing 200 miles a month doesn' help I suppose!  :smiley:

nice to see another minty colour thought mine was the loner on here.

mine must be fooked to! mine never gets to 90 only when in stand still traffic when cruising along its always between 80 mark and the first free lines. on average mpg it never goes over 25 but i do sometimes have a heavy foot  :laugh: it warms up nice after 5 mins say about a mile driving from cold. think mines due for a change?
