- 2009 Fusion 1.6 petrol automatic
Hello All,
My 2009 1.6 petrol automatic Fusion has a cooling problem.
It overheats intermittently. It can be fine for a week or two then will suddenly overheat as follows...
When driving, the temperature gauge sits at around 90 degrees, pretty rock solid. The car heater though is blowing only cold air. Then very SUDDENLY the temp gauge will shoot up to >200 deg and the warning light will come on with message ENGINE TOO HOT and there's steam coming from the coolant expansion tank etc. Leaving the engine off to cool, then topping up coolant and restarting the car, it will run fine again for a week or two.
It happens when I'm not on dual carriageways/motorways - as the weather is currently cold I'm guessing the flow of air is keeping everything reasonably cool at constant high speeds. But like I say, can be fine around town too for a week or two.
Funny thing is after these overheating episodes the heater blower starts blowing nice warm air.
Then the cycle repeats.
I've had a full electrical diagnostic run and the 2 stage fan, temp sensor etc are all working perfectly.
I'm thinking maybe a blockage somewhere in the cooling circuit or maybe the water pump isn't working properly. Any ideas?
