Hey everyone, I'm not really much good with cars, so I'm looking for some advice, please! Driving last night I saw the temp gauge was almost in the red, so I assumed there was a cooling problem. But the coolant tank is full, and there's no water in the oil; I haven't checked the pump yet, so I don't know if that's OK or not. But when I switched on the ignition this morning, the gauge was pointing at the 'N' of 'NORM', already about a quarter of the way across, instead of cold. So I'm wondering, is this a sensor problem or something? Any ideas?
