    Hyundai Accent running at a slightly elevated temperature

    Hyundai Hyundai Advice Hyundai Accent Hyundai Accent Advice Hyundai Accent 2001

    For a few weeks now, my 2001 Hyundai Accent has been running at a slightly elevated temperature. It is not affected by the hot weather, because it happens at night and on cool days too; there is no visible blockage/damage to the radiator or related parts; and the coolant (around one year old) is always filled to the top and there are no leaks. I never need to put any more in it. Nothing is being taken out of or put back into the overflow bottle. The temp increase is only slight, but I'm keen to attend to it in case it is indicative of a larger, later problem. Any advice you can give would be most welcome.

    If the increase in running temperature is only small and there is no loss of coolant there is probably nothing to be worried about. It could be a slight blockage in the radiator that’s affecting the coolant flow, a sticking thermostat, or something like that. You could flush the cooling system, check the thermostat and replace the coolant. If you replace the coolant make sure you use the correct coolant, which will be a mix of water and glycol.
