My car runs hot and there is no leaking hoses. The radiator is full and the fans work.it spews violent out of the plastic add tank. All fuses are good.
Hi. Sounds like you have a failed thermostat like stated earlier or possible failing of failed water pump. Thermostat is less than $10 but labor may get you if you can't do yourself. Cost on water pump is more along with labor. Install a fail-safe thermostat, it will fail in the open position instead of closed allowing coolant to still circulate within the engine and keep it cool, unlike a closed thermostat that will make car run hot and overheat. Only downfall is if it fails in the winter you will have little to no heat inside cabin.
