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 Volvo S60, start with a thorough visual inspection of the area beneath the vehicle, looking for any signs of coolant accumulation or stains that could indicate a leak. Next, monitor the coolant level in the reservoir; a consistent drop may suggest a leak that needs further investigation. Conducting a pressure test on the cooling system is a crucial step, as it can help pinpoint leaks by pressurizing the system and observing any pressure drops. Pay close attention to hoses, clamps, and connections, as these components are often the culprits behind leaks due to wear or damage. Additionally, inspect the radiator for any signs of corrosion or wet spots, and examine the water pump for any signs of seepage. Don’t overlook the heater core, which can leak and may produce a sweet smell inside the cabin. Finally, ensure the radiator cap is functioning properly by testing its pressure retention. If these steps do not reveal the source of the leak, it may be time to consult a mechanic for a professional assessment. This systematic approach not only helps in identifying the issue but also ensures that you address simpler problems before moving on to more complex diagnostics.
When dealing with coolant leaks in a 2019 Volvo S60, it's crucial to understand the common problems that may arise. One of the primary culprits is damaged hoses, which can develop cracks or degrade over time, leading to leaks in the engine compartment. Additionally, a faulty radiator can be a significant source of coolant loss, as leaks can occur directly from the radiator itself. Another potential issue is a worn-out water pump; if the pump malfunctions or its seals fail, it can result in coolant escaping from the system. It's also important to check the radiator cap, as a loose or damaged cap can allow coolant to leak out. In rare instances, a cracked engine block may be the cause of the leak, although this is less common. To effectively address these issues, regular maintenance and inspections are essential, as they can help identify and resolve coolant leaks before they lead to overheating or serious engine damage. By being proactive and knowledgeable about these common causes, DIY enthusiasts can take the necessary steps to maintain their Volvo S60 and ensure its longevity.
Addressing a coolant leak in your 2019 Volvo S60 is not just a matter of routine maintenance; it is an urgent issue that requires immediate attention. Coolant plays a vital role in regulating your engine's temperature, and any loss can lead to overheating, which may cause severe damage to engine components. Ignoring a coolant leak can escalate into more significant problems, including reduced fuel efficiency and increased repair costs. Moreover, a malfunctioning cooling system poses safety risks, as an overheated engine can lead to breakdowns or accidents on the road. Therefore, if you notice any signs of a coolant leak, such as puddles under your vehicle or a warning light on your dashboard, it is crucial to act swiftly. By addressing the issue promptly, you not only protect your engine from potential harm but also ensure your vehicle remains safe and reliable for your journeys.
