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 effectively diagnose a coolant leak in your 2012 Chrysler Town & Country, start with a thorough visual inspection of your vehicle. Begin by checking for any puddles of coolant beneath the car, as this can provide immediate clues about the source of the leak. Next, inspect the hoses connected to the radiator for any visible signs of damage, such as cracks or loose connections, which are common culprits. Don’t overlook the radiator itself; look for any signs of corrosion or leaks that could be allowing coolant to escape. If these initial checks do not reveal the issue, consider performing a pressure test on the cooling system, as this can help identify leaks that are not easily visible. Additionally, examine the water pump for any signs of wear or leakage, as this component is crucial for maintaining proper coolant circulation. Be alert for any white smoke from the exhaust, which may indicate coolant entering the engine, and monitor your coolant levels regularly to detect any consistent drops. By following this systematic approach, you can effectively narrow down the potential causes of the coolant leak and take appropriate action to resolve the issue.
When dealing with coolant leaks in a 2012 Chrysler Town & Country, it's essential to understand the common problems that may arise. One of the primary culprits is a damaged radiator, which can develop corrosion over time, leading to leaks. Additionally, a faulty radiator cap can disrupt the pressure balance within the cooling system, resulting in coolant escaping. Worn-out hoses are another frequent issue; as they age, they can crack or become brittle, allowing coolant to seep out. The water pump, responsible for circulating coolant, can also leak, particularly if its seals are compromised. In more severe cases, a cracked engine block may be the source of the leak, which requires immediate attention. Lastly, loose or damaged hose clamps can create weak points in the system, causing coolant to leak at connection sites. By being aware of these potential issues, DIYers can take proactive steps to inspect and maintain their vehicle, ensuring it runs smoothly and efficiently.
Addressing a coolant leak in your 2012 Chrysler Town & Country is not just a matter of routine maintenance; it is a critical safety concern that demands immediate attention. Coolant plays a vital role in regulating engine temperature, and any leak can lead to a rapid loss of coolant fluid, resulting in dangerously low levels that increase the risk of engine overheating. This overheating can cause severe damage to the engine, potentially leading to costly repairs or even complete engine failure. Furthermore, neglecting a coolant leak can exacerbate the problem, damaging essential components of the cooling system such as the radiator, water pump, and hoses. By addressing the leak promptly, you not only safeguard your vehicle's performance but also prevent more extensive and expensive repairs in the future. Therefore, if you notice any signs of a coolant leak, it is imperative to take action immediately to ensure the safe and efficient operation of your vehicle.
