The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.
When the head gasket begins to fail, the engine may have no symptoms at all. They only begin to occur when the leak has reached an engine oil passage, engine coolant passage or the engine cylinder.
When that happens, the engine may be very difficult to start, and run roughly when idling. There may be oil or coolant leaking, and the engine may begin to overheat, or at least run hot. At this point, there may be coolant in the engine oil pan — this will look creamy and lighter in color than the oil. Also, the radiator or engine coolant reservoir may have a gurgling sound, the presence engine oil, or smell of combustion. And the check engine light will come on.
The coolant being burned in the engine will produce white exhaust that smells sweet, like engine coolant. When the head gasket fails completely, the engine will overheat within minutes of starting, will stall and then won't restart.
A failing heater core may cause the car's interior to smell like engine coolant. The smell will become worse when the heater is turned on. The engine may also begin to run hotter until the vehicle is repaired.
The worst-case scenario is the engine overheating, which can cause extensive engine damage.
If the heater core is clogged, the air that blows when the heater is turned on will not be very hot.
Problems with the intake manifold gasket can create the following symptoms:

A failing radiator can cause the engine to run hot or overheat. Most radiators are made of metal and plastic. The plastic parts can become brittle and crack over time, causing a leak of coolant (typically green or pink in color). All manufacturers have a recommended service interval for coolant renewal. As the coolant ages, the additives breakdown and being to form solid deposits. These deposits will build up in the passages of the cooling system and will eventually clog components, including the radiator. A leaking or clogged radiator must be replaced. Some automatic transmission cars will also have a transmission cooler integrated into the radiator. Lines going to and from the transmission circulate transmission fluid to help cool the transmission in heavy duty applications such as towing or off-roading. If this integrated cooler fails, it can allow transmission fluid and coolant to mix. This will causing shifting issues in addition to overheating.
A coolant leak may be noted from the hoses. Coolant hoses can be damaged by oil leaks, or age. This will lead to swelling or cracking, it is suggested to replace the hoses before they begin leaking to avoid potential overheating.
The bad thermostat can cause two different sets of problems, depending on whether it's stuck open or stuck closed.
A thermostat that is stuck open can cause the engine to run colder than normal and turn on the check engine light. It may also cause poor fuel mileage and the heater to blow cool air.
A thermostat that is stuck closed will cause the vehicle to overheat. If a new thermostat doesn't resolve engine temperature problems, the cooling system needs to be checked for other issues.

The two most common signs of a bad pump are leaks and noises.
Leaking water pumps can result in damage to the drive and timing belts, and cause the engine to overheat. A failed water pump can be caused by other problems in the cooling system, such as a bad thermostat, radiator or head gasket.
To effectively diagnose a coolant leak in your 2022 Ram ProMaster City, start with a thorough visual inspection of the vehicle. Look for any signs of coolant pooling under the vehicle or around critical components such as the radiator, hoses, and water pump. Next, check the coolant level in both the reservoir and radiator; a noticeable drop can indicate a leak. If the initial checks do not reveal the source, consider performing a pressure test on the cooling system, which can help pinpoint leaks by pressurizing the system. Pay close attention to the radiator and hoses for any cracks or wear, as these are common culprits. Additionally, inspect the water pump and heater core for any signs of leakage. If you observe white smoke from the exhaust, this could signal coolant entering the combustion chamber, indicating a more serious issue. Should these steps not lead to a resolution, consulting a mechanic is advisable for a comprehensive diagnosis. By following this structured approach, you can efficiently identify and address coolant leaks in your vehicle.
When dealing with coolant leaks in a 2022 Ram ProMaster City, it's essential to understand the common problems that may arise within the cooling system. One of the primary culprits is damaged hoses, which can develop cracks or wear over time, leading to leaks. Additionally, a faulty radiator, whether due to corrosion or physical damage, can also be a significant source of coolant loss. It's important to check the radiator cap as well; if it is loose or damaged, it may fail to maintain the necessary pressure, resulting in leaks. Another area to inspect is the water pump, as leaks from this component can occur at the front of the engine. In more severe cases, a cracked engine block or worn-out gaskets, such as the head gasket, can lead to coolant leaks, although these issues are less common. Addressing these problems promptly is crucial to prevent overheating and potential engine damage, making it advisable for DIYers to conduct a thorough inspection and consider repairs as needed.
Addressing a coolant leak in your 2022 Ram ProMaster City is not just a matter of convenience; it is a crucial step in safeguarding your vehicle's engine and overall performance. Coolant plays a vital role in regulating engine temperature, and a leak can lead to overheating, which poses a serious risk of engine damage. If left unattended, the engine may run excessively hot, leading to catastrophic failures that could result in costly repairs or even total engine replacement. Moreover, a coolant leak can diminish your vehicle's efficiency, affecting fuel consumption and overall performance. Therefore, it is imperative to act swiftly upon noticing any signs of a coolant leak. By addressing the issue promptly, you not only protect your investment but also ensure the safe operation of your vehicle, preventing further complications down the road.
