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 effectively diagnose a coolant leak in your 2019 Land Rover Range Rover, begin with a comprehensive visual inspection of the vehicle. Look for any visible signs of coolant, such as puddles or white residue, which can indicate a leak. Next, check the coolant level in the reservoir; a sudden drop may suggest a leak that needs immediate attention. If these initial checks do not reveal the source, consider performing a pressure test on the cooling system, which involves pressurizing the system to help pinpoint any leaks. Pay close attention to the radiator and hoses, as they are common culprits for leaks due to wear and tear. Additionally, inspect the water pump and heater core for any signs of leakage, as these components can also contribute to coolant loss. Be alert for any steam or a sweet smell while driving, as these can be indicators of a coolant leak. If you are unable to identify the source after these steps, it may be wise to consult a mechanic for a more detailed inspection and repair. Following this diagnostic approach will help you systematically address the issue, starting with the simplest checks before moving on to more complex diagnostics.
When dealing with coolant leaks in a 2019 Land Rover Range Rover, it's essential to understand the common problems that may arise. One of the primary culprits is damaged hoses, which can develop wear and tear over time, leading to leaks. Additionally, a faulty radiator, whether cracked or corroded, can significantly contribute to coolant loss. It's also important to check the hose clamps; if they are loose or damaged, they may fail to create a proper seal, resulting in leaks. Another frequent issue is a leaking water pump, which can compromise the entire cooling system. Lastly, don't overlook the coolant reservoir, as cracks or damage here can also lead to coolant escaping. By being aware of these potential issues, DIYers can take proactive steps to inspect and address coolant leaks, ensuring the longevity and performance of their vehicle. Regular maintenance and timely repairs are crucial to prevent overheating and protect the engine from damage.
Addressing a coolant leak in your 2019 Land Rover Range Rover is not just a matter of routine maintenance; it is a crucial step in safeguarding your vehicle's performance and longevity. Coolant plays a vital role in regulating engine temperature, and a leak can quickly escalate into severe overheating, risking catastrophic engine damage. Ignoring this issue can lead to costly repairs and even complete engine failure, which is a scenario no vehicle owner wants to face. Furthermore, a coolant leak can diminish your vehicle's overall performance, resulting in decreased fuel efficiency and a less enjoyable driving experience. It is also important to recognize that a coolant leak may indicate underlying problems within the cooling system, such as a failing water pump or a damaged radiator. By addressing the leak promptly, you not only protect your engine but also prevent further complications that could arise from these more serious issues. Therefore, if you notice any signs of a coolant leak, it is imperative to act quickly and consider having it inspected by a qualified mechanic to ensure your vehicle remains safe and reliable on the road.
