Grand Vitara,2000 petrol,54 plate
Temp gauge reading normal most of the time but then without warning it's just before the red, it doesn't climb up slowly but more like blink and you miss it go from here to there.
Can drive for a while then the opposite where the needle is back to the normal position, sometimes creeps down or blink and you miss it again.
Checking water level next day when cold it's on the max mark and no water is lost.
I did recently change the anti freeze and thermostat as I thought it was the thermostat but it's still the same.
No air locks, heater has warm air, water level on expansion bottle on max line.
