A Mazda 6 owner's gauge climbed after several minutes stationary and fell with higher revs. The heater worked mainly while moving, and coolant needed topping up daily.
What the report actually shows
A thermostat and fan-control module had been changed, while the owner said the fans worked. The continuing coolant loss means the system still needed a leak and pressure investigation.
Reported outcome
The cited question did not report a confirmed repair.
What to take from this case
Do not interpret traffic-only overheating without the coolant-loss clue. Stop driving if the gauge rises toward the danger zone; investigate leaks and circulation with a cold, safe system.
