i'm losing water and coolant and have no heat
110,000 miles, i have added water and coolant three times in the past 2 weeks, there is no heat until i add water and coolant and then it is luke warm. temp gauge runs hot until coolant is added. Added water/coolant less than a week ago and again today, is there a leak in the radiator?
Loss of coolant because of a coolant leak is probably the most common cause of engine overheating. Possible leak points include hoses, the radiator, heater core, water pump, thermostat housing, head gasket, freeze plugs, automatic transmission oil cooler, cylinder head(s) and block.
