v70 T5 1999 - Coolant light is staying on

Does any one have any checks/tips etc. I can do to try and find the fault, I have check the oil and water levels etc. and both seem fine, could it be a faulty sensor? or is there something I have missed or not thought about (most probable)? Cheers anyway Sheep

Simply that if the question is only posted once, it makes life easier for everyone. Alastair ----------------------------
