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 2011 Volvo S60, begin by inspecting the coolant reservoir to ensure the fluid level is adequate. Next, visually check for any obvious signs of leaks beneath the vehicle or within the engine compartment. If no leaks are apparent, utilize a coolant pressure tester to pressurize the system, which can help identify hidden leaks. Pay close attention to the radiator hoses, as they can develop cracks or bulges over time. Additionally, examine the water pump and radiator for any signs of leakage or corrosion. Don’t overlook the heater core, especially if you detect a sweet odor inside the cabin, which can indicate a leak. It’s also wise to monitor the coolant levels over several days; a consistent drop can confirm the presence of a leak. If these steps do not reveal the source of the problem, consulting a professional mechanic may be necessary for further diagnosis and repair. By following this structured approach, you can systematically identify and address coolant leaks in your vehicle.
When tackling a coolant leak in your 2011 Volvo S60, it's essential to understand the common problems that may be contributing to the issue. One of the primary culprits is the condition of the hoses; over time, they can become brittle or develop cracks, leading to leaks. Additionally, the radiator is another critical component that can suffer from damage or corrosion, creating weak points where coolant can escape. Worn gaskets, which are designed to seal various connections within the engine, can also degrade, resulting in coolant loss. Furthermore, the water pump is a vital part of the cooling system, and any failures here can lead to significant leaks. Lastly, head gasket leaks are a serious concern, as they can not only cause coolant loss but also lead to more severe engine damage if not addressed promptly. To effectively identify a coolant leak, keep an eye out for visible drips under your vehicle, monitor for signs of engine overheating, and regularly check the coolant levels in the reservoir. By being proactive and inspecting these components, you can prevent further damage and costly repairs down the line.
Addressing a coolant leak in your 2011 Volvo S60 is not just a matter of convenience; it is a critical maintenance task that demands immediate attention. Ignoring a coolant leak can lead to severe engine overheating, which may result in catastrophic engine failure and costly repairs that can range from $1,000 to $2,000 or more, especially if the leak is due to a blown head gasket. Luxury vehicles like the Volvo S60 often come with higher repair costs, making it even more essential to act quickly. Furthermore, delaying repairs can exacerbate the problem, leading to more extensive damage that could require significant investment to fix. Therefore, if you notice any signs of a coolant leak, it is imperative to address the issue promptly to safeguard your vehicle's performance and longevity, ultimately saving you from more substantial expenses down the line.
