The symptoms you've described, including no heat, overheating, white smoke, and constant coolant loss, along with the error codes you provided, suggest a potential issue with the cooling system and engine performance. Given the severity of the symptoms and the complexity of potential issues, it's advisable to have the vehicle inspected by a qualified mechanic or a Dodge dealership. They can perform a thorough diagnosis, pressure tests, and use diagnostic tools to pinpoint the exact problems and recommend appropriate repairs. Otherwise, hers a list of codes and potential issues as well as testing that you can try on your own as long as you have the tools.
Error Codes:
P0157 and P0158 (O2 Sensor Circuit Low Voltage Bank 2 Sensor 2):
These codes relate to the oxygen sensor in the post-catalytic converter position on bank 2. It might be related to the P0430 code.
P0430 (Catalyst System Efficiency Below Threshold Bank 2):
This code indicates an issue with the catalytic converter's efficiency on bank 2, which could be connected to the oxygen sensor readings.
P0117 (Engine Coolant Temperature Sensor 1 Circuit Low):
This code suggests a problem with the engine coolant temperature sensor circuit.
P2181 (Cooling System Performance):
This code points to an issue with the cooling system's overall performance.
Symptoms:
No Heat: This can be a result of low coolant levels or a malfunctioning thermostat.
Overheating: The engine overheating could be due to insufficient coolant, a faulty thermostat, or a malfunctioning cooling fan.
White Smoke: White smoke can indicate coolant entering the combustion chamber, possibly due to a blown head gasket.
Possible Causes:
Coolant Leak: The fact that the coolant is always empty suggests a coolant leak. The leak could be internal (e.g., head gasket) or external (e.g., a hose or radiator leak).
Faulty Thermostat: A stuck-closed thermostat can lead to overheating and a lack of heat in the cabin.
Cooling System Issues: Problems with the water pump, radiator, or cooling fan can contribute to overheating.
Oxygen Sensor and Catalytic Converter Issues: The codes related to the oxygen sensor and catalytic converter might be secondary issues caused by the overheating problem.
Recommendations:
Address Coolant Leak: Investigate and repair the coolant leak. Since there's no external leak, it could be internal, possibly a blown head gasket. A cooling system pressure test may help identify the source of the leak.
Check Thermostat: Test or replace the thermostat to ensure proper coolant flow.
Inspect Cooling System Components: Examine the water pump, radiator, and cooling fan for any malfunctions.
Verify Oxygen Sensor Function: Address the issues with the oxygen sensor and catalytic converter after resolving the cooling system problems.

Does it only happen when you try to turn on the heat?? If so it could be the heater core or a hose, but if it loses it all the time, I would check the water pump!!

Hi there,
The multiple trouble code indicates various problems happening at the same time with your vehicle. Please click the corresponding link of each trouble code to get an idea what it means and what to replace. See this:
1. P0157 code is triggered when the power train module detects a problem with the downstream/rear oxygen sensor.
2. P0158 code shows a faulty oxygen sensor, bad sensor heater circuit, and a rich running condition (lower fuel economy).
3. P0430 code shows a defective oxygen sensor mounted near the catalytic converter, engine bank 2 (catalyst system efficiency below threshold).
4. P0117 code shows a faulty engine coolant temperature sensor. It causes check engine light, poor fuel economy, and an overheating engine.
5. P2181 code stands for "cooling system performance." It is commonly caused by low coolant level, a faulty thermostat, and intermittent issues with the coolant temperature sensor.
Click the following link from our website's resource database blog for more details of each trouble code (https://www.carparts.com/blog/guides/). Simply enter each code on the search box to access the detailed explanation and included DIY videos. I hope this helps!

White smoke coming out the exhaust pipe is a sign of coolant being burned in the cylinder during the combustion process. A lot of your symptoms might also lead to a bad head gasket, which would allow coolant to enter the cylinder. That would also cause the car to overheat.

Or could be a bad intake seal allowing coolant to leak where it shouldn't leak into

Head gasket is bad junk car or junkyard motor install
