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 2018 Volvo V60 Cross Country, start with the simplest checks before moving on to more complex diagnostics. Begin by inspecting the area beneath your vehicle for any puddles of coolant, which can be easily identified by their bright green, orange, or pink color. Next, examine the radiator and hoses for visible signs of wear, such as cracks or wet spots, as these can often be the source of leaks. If no obvious leaks are found, consider performing a pressure test on the cooling system; this method can help pinpoint hidden leaks by pressurizing the system and revealing weak spots. Additionally, inspect the water pump, as a malfunctioning pump is a common culprit for coolant leaks. Don’t forget to check the heater core, as leaks here can lead to coolant entering the cabin. Finally, assess the head gasket for any signs of failure, such as coolant mixing with oil or unusual exhaust smoke, which could indicate a more serious issue. By following this structured approach, you can systematically identify and address the source of the coolant leak in your vehicle.
When addressing coolant leaks in a 2018 Volvo V60 Cross Country, it's crucial to recognize the common problems that may arise within the vehicle's cooling system. A faulty radiator is often a primary suspect, as it can develop cracks or holes over time, leading to significant coolant loss. The water pump, responsible for circulating coolant, can also be a source of leaks if it becomes damaged or if its gasket fails. Additionally, worn-out hoses are frequently encountered issues; they can deteriorate and crack, allowing coolant to escape. It's essential to inspect hose clamps as well, since loose or damaged clamps may fail to secure the hoses properly, resulting in leaks. The heater core, which plays a vital role in the vehicle's heating system, can develop leaks that may cause coolant to seep into the cabin or onto the ground. In more severe cases, a cracked engine block can lead to coolant leaks, a serious issue that typically requires professional intervention. Promptly addressing these issues is vital to prevent overheating and protect the engine from damage. If you suspect a coolant leak, conducting a thorough inspection or consulting a qualified mechanic for repairs is highly advisable.
When it comes to a coolant leak in your 2018 Volvo V60 Cross Country, urgency cannot be overstated. Coolant plays a vital role in maintaining optimal engine temperature, and any leak can lead to overheating, which poses a significant risk to your engine's health. If left unchecked, the engine may run excessively hot, leading to catastrophic failures that could result in costly repairs or even total engine replacement. Additionally, a coolant leak often signifies underlying issues within the cooling system, such as a compromised radiator or a failing water pump. By addressing the leak promptly, you not only safeguard your engine from immediate damage but also prevent further complications that could arise from neglecting the problem. Therefore, if you notice any signs of a coolant leak, it is crucial to take action swiftly to ensure the longevity and safety of your vehicle.
