jonp Posted April 12, 2009 Share Posted April 12, 2009 This question is about a 1.8 petrol Ford Focus. I would like to know from any mechanics about what the possible causes may be for the following symptoms : 1. When starting the car from cold in the morning and during the first journey the temperature guage needle after rising slightly then drops slightly (I sometimes actually see it happen) when for example stopped at traffic lights. 2. Secondly, after switching off the engine and then I turn the ignition such that the engine is off but the temperature guage is functional, the needle usually has dropped quite a bit from the mid position even though I have only just switched the engine off (so it is still hot). 3. Lastly, I feel the needle is never exactly mid way between cold and hot but slightly nearer the cold end. Would this suggest a head gasket problem ? Would any of these symptoms suggest a problem with the coolant pump, radiator or any related component ? Quote Link to comment Share on other sites More sharing options...
w2575 Posted April 12, 2009 Share Posted April 12, 2009 Is this a focus MK 1 or 2 ? Quote Link to comment Share on other sites More sharing options...

Renew the thermostat but make sure it's a genuine Ford one with a Ford gasket otherwise it will not last five minutes. Should clear the problem.
