Hello, recently I've noticed my car is going just below 90oC on the temperature guage.
It'll be fine for ages, but thenn if I'm on the motorway and there's a steepish hill going down the temperature guage will show it's abit below 90oC, then I carry on driving then it'll go back up to 90oC again and be happy, then another hill may come and same thing.
I using the above about the temprature, as I recently just done 400 miles going to and back from newquay and it happened then.
A few weeks ago I believe I saw the same issues driving to work (non motorway) I'm sure I had the heater on and looked at the temperature guage and it wasn't at 90oC, when it should be.
I'm not too sure if this is a coolant temperature sensor or a thermostat (hopefully not more!)
Anyone know which it may be?
