2008 Hyundai Tucson Q&A
2008 Hyundai Tucson Question: Why would the temperature gauge run high?
Yes they are related. You need to immediately check the coolant level (when vehicle is cold) do not remove cap when hot. If level is low fill it to correct level and have the cooling system pressure checked. If level is not low have it checked by a repair shop ASAP. - Chevy Power
