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.
When diagnosing a coolant leak in your 2020 Ram 2500, it's essential to adopt a systematic approach that begins with simple visual inspections and progresses to more complex diagnostics. Start by conducting a thorough visual inspection of the vehicle, focusing on areas around the radiator, hoses, and water pump for any visible signs of coolant leakage. Next, check the coolant levels in both the reservoir and radiator; a significant drop may indicate a leak. If these initial checks do not reveal the source, perform a pressure test on the cooling system, which can help pinpoint leaks by observing any pressure drops. Additionally, inspect all hoses and connections for wear or damage, tightening or replacing any compromised components. Pay special attention to the radiator for signs of corrosion or leaks, as well as the water pump, which can also be a common source of coolant leaks. Finally, be alert for any white smoke from the exhaust, as this could signal a more serious issue, such as a blown head gasket. By following this structured diagnostic approach, you can effectively identify and address coolant leaks in your vehicle.
When dealing with coolant leaks in a 2020 Ram 2500, it's essential to understand the common culprits that may be at play. One frequent issue is damaged hoses, which can develop cracks or wear over time, leading to leaks in the cooling system. Additionally, a faulty radiator, whether due to corrosion or physical damage, can also be a significant source of coolant loss. Another area to inspect is the radiator cap; if it is loose or damaged, it may not seal properly, resulting in leaks. The water pump, responsible for circulating coolant, can also develop leaks, which can be detrimental if not addressed. In more severe cases, a cracked engine block or worn-out gaskets, such as the head gasket, can lead to significant coolant leaks. Identifying these issues early is crucial, as neglecting them can lead to overheating and serious engine damage. If you suspect a coolant leak, conducting a thorough inspection of these components can help you determine the source and decide whether a DIY repair is feasible or if professional assistance is needed.
Addressing a coolant leak in a 2020 Ram 2500 is of utmost urgency due to the significant risks associated with engine overheating and potential failure. Coolant plays a vital role in maintaining optimal engine temperature; a leak can disrupt this balance, leading to overheating that may cause irreversible damage to engine components. Ignoring the signs of a coolant leak not only jeopardizes the engine's health but can also diminish the vehicle's overall performance and fuel efficiency. Furthermore, the longer the leak goes unaddressed, the more costly the repairs can become, as minor issues can escalate into major engine problems. For the safety of both the driver and the vehicle, it is crucial to promptly identify and repair any coolant leaks to ensure reliable operation and prevent serious damage down the line.
