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 Evoque, start with a thorough visual inspection of the vehicle. Look for any visible signs of coolant pooling under the car or around critical components such as the radiator, hoses, and water pump. Next, check the coolant level in the reservoir; a sudden drop can be a clear indicator of a leak. If these initial checks do not reveal the source, consider performing a pressure test on the cooling system. This involves pressurizing the system and monitoring for any pressure drops, which can pinpoint leaks. Pay special attention to the radiator, as corrosion or damage here is a common culprit. Additionally, inspect all hoses and connections for wear or cracks, tightening or replacing any that appear compromised. Don’t overlook the heater core, especially if you notice unusual smells or fogging inside the vehicle, as this can also signal a leak. If you still cannot identify the source after these steps, it may be time to consult a qualified mechanic for further assistance. By following this structured approach, you can efficiently diagnose and address coolant leaks in your vehicle.
When addressing coolant leaks in a 2019 Land Rover Range Rover Evoque, it's vital to recognize the common problems that can affect the vehicle's cooling system. One of the primary culprits is damaged hoses, which can develop cracks or degrade over time, leading to coolant escaping from the system. Additionally, a faulty radiator is often a significant source of leaks; as it ages, it may form cracks or holes that allow coolant to seep out. Another critical component to inspect is the water pump, as wear and tear can compromise its ability to circulate coolant effectively, resulting in leaks. Furthermore, a loose or damaged radiator cap can disrupt the pressure within the cooling system, causing coolant to leak. In more severe cases, a cracked engine block may be the culprit, which typically requires professional repair due to the complexity and potential for significant engine damage. If you notice signs of a coolant leak, such as puddles under your vehicle or consistently low coolant levels, addressing these issues promptly is crucial to maintaining your vehicle's health and preventing further damage.
When it comes to a coolant leak in your 2019 Land Rover Range Rover Evoque, urgency cannot be overstated. Coolant plays a vital role in maintaining optimal engine temperature, and any leak can lead to overheating, which poses a serious risk of engine damage. If left unchecked, the engine may run excessively hot, leading to catastrophic failures that could result in costly repairs or even complete engine replacement. Additionally, a coolant leak can compromise your vehicle's overall performance, potentially leaving you stranded if the situation deteriorates while driving. By addressing the leak promptly, you not only safeguard your engine but also enhance the longevity of your vehicle's cooling system. Therefore, if you notice any signs of a coolant leak, it is crucial to take immediate action to prevent further damage and ensure your vehicle remains safe and reliable on the road.
