Could be from a variety of things. Commonly overheating occurs when the car is low on coolant, broke thermostat or the radiator needs repairs.
Low coolant? Radiator plugged or restricted? Cooling fan not working? Water pump not circulating coolant? Thermostat not opening? Cooling system airbound?
It sure is. Leaking radiator fluid only causes the coolant system to de-pressurize and not effectively cooling all the internal working engine parts. As to repair costs, one needs to evaluate the cost of repairs vs replacing the radiator. If the car is older, then replacing the radiator might be the way to go.
Assuming repairs have been performed properly and there are no DTC's; you have an electrical problem.
First, you must find out WHERE it's leaking. If it's a radiator hose or heater hose, replace the hose. If it's a water pump leak, replace the water pump. If it's a leaking radiator, take it to a radiator shop and have the radiator replaced or repaired. If it's a freeze plug, head gasket or other leak, you'll need more serious repairs.
If you need to get your radiator repaired you need to seek a qualified mechanic so you do not cause further and more expensive damaged to your radiator.
Per the owners manual. "Use only a high quality Ethylene glycol based antifreeze coolant, such as Mopar P/N 4267020 or equivalent" Your best bet is to drain all the coolant both from the radiator and the engine block and then flush with water and then use all one brand of coolant, such as Prestone that is sold everywhere if your doing some major repairs like replacing hoses and what not.
If there is no water in the radiator and the reserve tank is full on any vehicle, you realize you have a leak and you fix it before you wreck your engine. First: fill your radiator with water. Look for a leak. If you see that a hose is leaking, yell "Hallelujah." You have the least expensive of all repairs facing you. In that case, you take off all four hoses, the two cooling hoses to the engine and the two heater hoses. You take them to the parts shop and get replacement hoses and put those on the vehicle. When one hose breaks, the others will break soon so you replace all of them at once. You purchase a new thermostat. You will replace the thermostat as well. You take out the old thermostat and leave it off. You will start filling the radiator with coolant instead of water this time. When the level of coolant gets to the level of the thermostat hole, then you install the new thermostat. Then you keep filling the radiator until it is full. You start the engine. Eventually the thermostat will open with a gulp. The level of coolant in the radiator will drop. You fill the radiator with coolant and close the cap. If there is not a leak in a hose, you call a mechanic.
Driving with low coolant in the radiator will allow air into the cooling system, and result in overheating. Severe overheating will damage the engine, and could lead to costly repairs. A low coolant reservoir (the plastic bottle) indicates you are loosing fluid somewhere. It's cheaper to find out where, then replace an engine. Caution! NEVER open the radiator on a hot engine. The heated water is well over 200 degrees and under pressure, and could severely burn you. Wait until the engine is cool to the touch and the hoses can be easily squeezed, indicating that the pressure has bled down enough to open the radiator safely.
Caution, coolants can be very hot and cause injury, plus they are very dangerous to pets; the sweet taste of coolant can kill your pets.Use safety glasses.Be sure the coolant has cooled down and one uses a rag or cloth before safely removing the radiator pressure cap.Attach a hose to the bottom fitting of the draincock located at the lower bottom left of the radiator…this hose should empty into a two gallon bucket.The drain plug tab should be in a vertical position before turning.Turn the plug CCW 1/4 turn, and then pull out slightly while turning CCW to the last 1/4 turn.The plug only turns ½ turn. Go any further; you could damage the plug.Coolant should now be flowing into the bucket, if not, there could be blockage inside the valve.Please don't damage the plug or body, radiators are very expensive.You may have to remove the bottom radiator hose if the valve is blocked to drain the coolant…This can be very messy…Prevent coolant from splashing into your eyes or face, whereas injuries can occur.Warning, keep rags, loose clothing and body parts away from fan blades when engine is running.After repairs, fill the cooling system with new coolant if necessary, and allow air to escape with cap off during engine warm up until radiator coolant level stabilizes at normal temp before adding additional coolant and securing the cap.Note hot coolant may overflow from the fill neck at the top of the radiator…Use caution to prevent burns!The radiator cap should be in good condition…no cracked rubber or broken spring. If the cap is defective, one may wonder where is all the coolant going and why is the coolant over heating?Coat the two rubber pieces inside the cap with coolant to help make a good seal to prevent vacuum and coolant losses. Remember to top off the coolant recovery tank to the proper level.
