    thermostat stuck open for sure. it heats up in idle as there is no airflow over the rad, when driving the rad overcools and it drops to 60ish.

    Can be bought about by dropping the coolant and refilling, as you can dislodge crap in the system, or maybe just bad luck.

    Either way, a new stat is about £12, and about 30 mins to fit.
