I think my focus (1.8 petrol titanium 2008 model) has been running hot of late - lumpy idle tick over, fuel consumption down and cuts out now and again.

had engine running today in diagnostics mode so I could monitor temperature whilst running.

Got temp up to 136 deg c on digital display which is what the temps have been when I have checked it in the week - Although fans didnt kick in at all so it must be running too hot and it must be a problem with the fan - saying that the fan kicks in when you put A/C on (not sure if this car has a 2-fans or not - i.e 1 for A/C and 1 for cooling) - could this be a fault with a thermostat or somekind of sensor do you think or ECU relat6ed. The hoses on the coolant tank were all hot and the coolant fluid inside was close to boiling when temp up at 136 deg c

oil levels and coolant levels were all okay also - checked around the oil cap and this was okay.

temp gauge in vehicle remains in centre (normal) but I believe this is only a reassurance indicator across the avergae engine temperature?

Not going to use vehicle now - its going into ford on tuesday for a check - I have been driving it this week 15 miles to work and 25 miles back - hopefully now long term damage has been caused with me driving it running hot!
