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.

If a vehicle is overheating, a bad thermostat could be the problem, and a damaged thermostat housing is more likely to produce a coolant leak, either from a cracked or warped housing or a failed seal to the engine. The thermostat housing can be made of metal or plastic. And the housing can be a stand-alone part that is separate from the thermostat, or (on later model vehicles) can be integrated with the thermostat and replaced as a single unit.
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 2013 Volvo S60, start by inspecting the coolant reservoir for any signs of low fluid levels, as this is often the first indicator of a leak. Next, pay attention to any unusual symptoms such as a sweet smell or colorful puddles forming under the vehicle, which can signal coolant leakage. It's also crucial to monitor the engine temperature; if you notice any overheating, this could be a direct consequence of a coolant leak. Conduct a thorough visual inspection of the radiator, hoses, and surrounding engine components to identify any visible signs of leakage. If these initial checks do not reveal the source of the problem, consider performing a pressure test on the cooling system, which can help uncover hidden leaks that may not be immediately apparent. Should you still be unable to locate the leak or if the issue persists, it may be wise to consult a professional mechanic for further assistance. By following this structured diagnostic approach, you can efficiently identify and address coolant leaks in your vehicle.
When diagnosing a coolant leak in a 2013 Volvo S60, it's crucial to consider several common problems that could be at play. Start by examining the hoses, as they are often the first culprits; old or worn hoses can develop cracks or breaks, particularly at the joints where stress is highest. Next, inspect the radiator for any signs of damage or corrosion, as rust or debris can lead to leaks that may not be immediately visible. Additionally, be aware that coolant loss might not always stem from an external leak; hidden issues such as a failing water pump or internal engine problems, like a faulty head gasket or cracked cylinder heads, can also contribute to coolant consumption without any external signs. Regular maintenance and thorough inspections are essential to catch these issues early, ensuring your Volvo S60 remains in optimal condition and preventing more significant repairs down the line.
Addressing a coolant leak in a 2013 Volvo S60 is of utmost urgency due to the severe consequences that can arise from neglecting this issue. Coolant leaks can lead to engine overheating, which poses a significant risk to the integrity of engine components. If left unaddressed, the overheating can result in catastrophic engine damage, leading to costly repairs or even complete engine failure. Symptoms such as puddles of coolant under the vehicle, fluctuating temperature readings, and a sweet odor should not be ignored, as they indicate a malfunctioning cooling system that requires immediate attention. By promptly identifying and repairing coolant leaks, you not only safeguard your vehicle's performance but also protect yourself from the financial burden of extensive repairs. Therefore, it is essential to act quickly to ensure the longevity and reliability of your 2013 Volvo S60.
