Hi All,

I've had my focus for six months now, and since January, the temperature gauge fluctuates whilst driving. I've changed the coolant, thermostat, and temp sensor already, with a slight improvement.

Strangely on a long run of about 60 miles a few days back the need held in the halfway point, even at idle on the way home.

Every other journey it bounces around between medium and 1/4 warm. Is there anything else I should look for / be worried about?

Car is on 75k with FSH.

Thanks for any advice.
