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 diagnose a coolant leak in your 2015 Mini Cooper Paceman, start with a thorough visual inspection of the engine bay and under the vehicle, looking for any signs of coolant pooling or wet spots that could indicate a leak. Next, check the coolant level in the reservoir; a consistent drop in coolant can signal a leak that needs attention. If these 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 hoses, as they are common culprits for leaks due to wear or damage. Additionally, inspect the water pump for any signs of leakage, as it can also fail over time. Lastly, ensure that the thermostat is functioning properly, as a malfunction can lead to coolant leaks and overheating. If you are still unable to locate the leak after these steps, it may be wise to consult a professional mechanic for a more comprehensive diagnosis. By following this structured approach, you can effectively troubleshoot and resolve coolant leak issues in your Mini Cooper Paceman.
When dealing with a coolant leak in a 2015 Mini Cooper Paceman, it's essential to understand the common problems that may be at play. One frequent culprit is loose hose connections, which can allow coolant to escape under pressure. Additionally, a broken radiator can lead to significant leaks, as it is a critical component that holds and circulates coolant throughout the engine. Another potential issue is a failed water pump, which not only affects coolant circulation but can also result in leaks if the pump's seals are compromised. If you encounter a P0128 code, it may indicate a faulty coolant thermostat, which can also contribute to coolant loss. It's crucial to address these issues promptly, as even a small leak can escalate over time, leading to more severe engine problems and costly repairs. By being proactive and checking these common areas, you can effectively manage and resolve coolant leak issues in your Mini Cooper Paceman.
Addressing a coolant leak in your 2015 Mini Cooper Paceman is not just a matter of routine maintenance; it is an urgent necessity. Ignoring a coolant leak can lead to severe overheating, which may cause irreversible engine damage and significantly impair your vehicle's performance. The longer you wait to fix the leak, the more likely you are to face costly repairs and safety hazards, as a compromised cooling system can lead to engine failure while driving. Regularly inspecting your vehicle for signs of coolant leaks and taking immediate action when you notice any symptoms is essential for maintaining the health of your car. By prioritizing this issue, you not only protect your investment but also ensure your safety on the road.
