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 2015 Land Rover Range Rover, it's essential to adopt a systematic approach that begins with the simplest checks before moving on to more complex diagnostics. Start by checking the coolant level in the reservoir; a significant drop can indicate a leak. Next, visually inspect the area under the vehicle and the engine bay for any signs of coolant, such as puddles or pink fluid, which is a common color for coolant. If no obvious leaks are found, consider performing a pressure test on the cooling system, as this can help pinpoint hidden leaks by revealing drops in pressure. Additionally, thoroughly examine all hoses, clamps, and connections for wear or cracks, as these are often culprits in coolant leaks. Pay special attention to the water pump and thermostat, as both can contribute to leaks if they are malfunctioning. Finally, monitor the coolant levels over time; a consistent drop will confirm the presence of a leak that needs addressing. By following this diagnostic approach, you can effectively identify and resolve coolant leaks, ensuring your vehicle remains in optimal condition.
When dealing with coolant leaks in a 2015 Land Rover Range Rover, it's crucial to understand the common problems that may arise. One frequent culprit is loose hose connections, which can lead to coolant escaping under pressure. Additionally, a broken radiator can cause significant leaks, as it is a vital component of the cooling system that can deteriorate over time. Another common issue is a failed water pump, which not only affects coolant circulation but can also lead to overheating if not replaced promptly. Other factors contributing to low coolant levels include leaks within the coolant system, a malfunctioning thermostat, and a defective water pump. To prevent these issues, regular maintenance and thorough inspections of the cooling system are essential, allowing DIY enthusiasts to catch potential problems early and ensure their vehicle operates smoothly.
Addressing a coolant leak in your 2015 Land Rover Range Rover is not just a matter of routine maintenance; it is a critical issue that demands immediate attention. Coolant plays a vital role in regulating engine temperature, and a leak can lead to overheating, which may result in severe engine damage if left unchecked. Moreover, neglecting a coolant leak can compromise your vehicle's performance, leading to more extensive and costly repairs down the line. It's essential to recognize that coolant leaks often signal underlying problems, such as damaged hoses, radiator issues, or water pump failures, which require prompt intervention to prevent further complications. Ignoring these symptoms can ultimately render your vehicle inoperable, posing safety hazards on the road and increasing the risk of breakdowns. Therefore, if you notice any signs of a coolant leak, it is crucial to address the issue immediately to ensure the longevity and safety of your vehicle.
