i have a 1996 V. Astra. At 60mph reading about 92 degrees on temp gauge, when in town temp will rise to 98 deg., fan cuts in and works ok, then goes down to about 96 deg., and will stay at this temp. When starting off from cold, within a mile its up to 92 deg. Is this abnormally high? i.e. what could the problem be - thermostat? air lock? water pump?
Thanks in advance for any advice !! Mike
