ok I have a 98 mark 8.I am having an overheating problem.My mileage is over 130000 with no water visible on the dipstick,but plenty of oil.I have no cooling fan at anytime including during startup or with ac on.Upper and lower radiator hoses feel hot along with the radiator.Oddly no heat at the heater core hoses,they feel empyty or full of air.Specifivcly where is the thermostat located.Also my 40 amp fuse is good and the fan spins freely.I will get a multi meter tomorrow to test for voltage at the fan.Where is the "LLC"?
