Thermostat working properly??

  1. #1
    Straight to the point, on a journey it will take roughly 10 mins for the needle to get the the middle, from then on if i stop in traffic atall the needle goes over and the fan starts then cools it down in a minute or so.

    Just had a 20 mile motorway drive at 75-80 then parked up for a bit while i wait for someone and the needle goes all the way to 3/4 and the fan stayed on for a good 5 minutes to get it to half way.

    Isnt the thermo supposed to release the hot water and usually the needle drops a bit when doing so to bring fresh in?? Im sure my x reg mk2 1.1 did that and the fan on occasions, or is it just the 1.6 difference to the 1.1?

    Help appreciated been playing my mind for ages! Debating on doing a fresh water and coolant service along with a new thermo sensor, is it working right?
