Largest of the two fans has started coming on from cold up to 90. Then its intermittent when in traffic, in traffic it can be between 30 seconds to several minutes.
When its been running at normal running temp for say ten mins the car is fine and the fan doesn't cut in.
Is this the thermostat thats causing this? need replacing?
Car runs absolutely fine, there is no excess heat coming from the engine, economy is the same etc.
Any help would be much appreciated.
