Like I say its not a problem, but Ive never had a car to do it yet before and this is my fourty somthing car now! I just like to know everything is perfect. Plus I just worked out my mpg from the last few miles since changing the thermo and its 31.6! Considering I mainly do motorway journeys at 65-70mph I think that should be better from what I have been searhcing across the forums.
