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.

If a vehicle is overheating, a bad thermostat could be the problem, and a damaged thermostat housing is more likely to produce a coolant leak, either from a cracked or warped housing or a failed seal to the engine. The thermostat housing can be made of metal or plastic. And the housing can be a stand-alone part that is separate from the thermostat, or (on later model vehicles) can be integrated with the thermostat and replaced as a single unit.
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 diagnose a coolant leak in your 2020 Ram 1500 Classic, start by checking for any visible puddles of coolant beneath your vehicle, as this can quickly indicate the presence of a leak. Next, inspect the hoses and connections for any signs of wear, cracks, or loose fittings that could be contributing to the issue. If no obvious leaks are found, consider performing a pressure test on the cooling system, which can help pinpoint hidden leaks. Pay special attention to the radiator, as corrosion or damage here is a common culprit. Additionally, examine the water pump and heater core for any signs of leakage, as these components can also lead to coolant loss. Finally, inspect the head gasket for any signs of damage, as a failing gasket can result in significant coolant leaks. Throughout this process, monitor your coolant levels regularly to track any changes, which can provide further clues about the leak's severity and location. By following this structured approach, you can effectively diagnose and address coolant leaks in your vehicle.
When addressing coolant leaks in a 2020 Ram 1500 Classic, it's vital to recognize the common problems that may be at play within the cooling system. One frequent issue is the deterioration of hoses, which can crack or develop leaks over time due to the constant exposure to heat and pressure. Additionally, the radiator itself can be a source of leaks, as it may develop holes or cracks that allow coolant to escape. The water pump is another critical component; if it fails, coolant can leak from the pump or its gasket, compromising the system's overall performance. More serious concerns, such as a cracked engine block, can also lead to significant coolant loss and require immediate professional intervention to prevent severe engine damage. Lastly, a loose or damaged radiator cap can disrupt the necessary pressure within the cooling system, resulting in coolant leakage. If you observe signs of a coolant leak, such as fluid pooling under your vehicle or an increase in engine temperature, it's essential to investigate these common issues promptly to maintain the health of your Ram 1500 Classic.
Addressing a coolant leak in your 2020 Ram 1500 Classic is not just a matter of convenience; it is a crucial step in maintaining the health and performance of your vehicle. Coolant is essential for regulating engine temperature, and a leak can lead to overheating, which poses a significant risk of severe engine damage. If left unchecked, the engine may run excessively hot, leading to potential breakdowns or catastrophic engine failure. Moreover, a coolant leak can adversely affect your vehicle's overall performance, resulting in decreased fuel efficiency and compromised engine functionality. By tackling the issue early, you can avoid more extensive and costly repairs down the line. Therefore, it is imperative to diagnose and repair any coolant leaks as soon as possible, ensuring your Ram 1500 Classic operates efficiently and remains in optimal condition.
