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 tackling a coolant leak in your 2013 BMW X1, it's essential to adopt a systematic diagnostic approach. Begin with a thorough visual inspection of the engine bay, paying close attention to hoses, connections, and the radiator for any visible signs of coolant escaping. This initial step can often reveal obvious leaks or damaged components. If the source isn't immediately apparent, proceed to conduct a pressure test on the cooling system. This involves using a pressure tester to pressurize the system, which can help identify leaks that may not be visible under normal conditions. Additionally, check the coolant reservoir for any signs of low coolant levels or cracks, as this component can often be a culprit in leaks. By following these steps, you can effectively narrow down the source of the leak, allowing for timely repairs and preventing further engine damage.
When dealing with coolant leaks in a 2013 BMW X1, it's crucial to understand the common culprits that may be at play. One frequent issue is radiator leaks, which can occur due to the radiator's complex design and multiple passages that may corrode or crack over time. Another significant source of leaks is the water pump; if it fails, it can lead to substantial coolant loss. Additionally, the hoses within the cooling system are prone to deterioration, which can result in leaks as they age. Don't overlook the coolant reservoir cap, as a faulty cap can also allow coolant to escape. Lastly, problems with the thermostat housing can contribute to leaks, making it essential to inspect this area as well. Addressing these issues promptly is vital to prevent overheating and potential engine damage, so regular inspections and timely repairs are key to maintaining your BMW X1's performance and longevity.
Addressing a coolant leak in your 2013 BMW X1 is not just a matter of routine maintenance; it is an urgent necessity that can prevent catastrophic engine damage. When coolant leaks occur, they can lead to overheating, which poses a serious risk to your engine's integrity. Ignoring this issue can result in costly repairs, as prolonged exposure to low coolant levels can damage vital components such as the water pump, radiator, and hoses. Moreover, the longer you wait to address the leak, the more extensive the damage can become, potentially leading to a complete engine failure. For DIY enthusiasts, it is crucial to act swiftly upon noticing any signs of a coolant leak, as early detection and repair can save you from significant financial burdens and ensure the longevity of your vehicle. Taking immediate action not only safeguards your engine but also enhances your overall driving experience by maintaining optimal vehicle performance.
