Can jeep run if coolant was added to engine?
Coolant added to engine oil? It would run but it would do serious damage to internal parts of the engine and drastically shorten the life span of the engine. Don't run it! Have the oil and filter changed NOW.
Why is the 2001 jeep Cherokee overheating causing the coolant fan to turn on then continue to run after engine has been turned off?
usually coolant leaks come from bad gaskets... or a bad water pump.. i would say drain the system and run water through the radiator (do NOT drive with water in the radiator, your engine will surely overheat!) and see if you can spot where the coolant is coming from... if it is coming from the engine block then you might have bad gaskets.. if not then it's the water pump.
Coolant, usually referred to as "antifreeze," protects the engine as pure water cannot. Added to water, the coolant raises the boiling point, lowers the freezing point, protects against corrosion and lubricates the water pump. In a pinch, you can run the engine on water but you will get the best service from your engine if you keep a good charge of coolant in the cooling system.
