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 2017 Volvo S60, start with a thorough visual inspection of the vehicle. Begin by checking for any visible leaks beneath the car, as puddles or stains can provide immediate clues. Next, inspect the radiator for signs of damage or leaks, looking for wet spots or white residue that may indicate coolant escaping. Pay close attention to the hoses connected to the radiator; any cracks or bulges could be the source of the leak. If these initial checks do not reveal the problem, consider performing a pressure test on the cooling system, which can help pinpoint leaks by pressurizing the system with air. Additionally, examine the water pump for any signs of leakage, as a malfunctioning pump can contribute to coolant loss. Don’t overlook the heater core, especially if you notice a sweet smell inside the cabin or fogging on the windshield, as these can be indicators of a leak. Finally, keep an eye on the coolant levels in the reservoir; a sudden drop can signal a leak that needs immediate attention. If you’re unable to identify the source of the leak after these steps, consulting a mechanic may be necessary for a more detailed inspection and repair.
When dealing with coolant leaks in a 2017 Volvo S60, it's essential to understand the common problems that may arise. A faulty radiator is often a primary culprit, as damage or corrosion can lead to significant leaks. Additionally, worn-out hoses are another frequent issue; over time, these hoses can degrade, resulting in leaks that may go unnoticed until they cause overheating. The water pump is also a critical component to inspect, as leaks from this part can occur at the front of the engine, leading to coolant loss. In more severe cases, a cracked engine block can be the source of leaks, which requires immediate attention to prevent extensive damage. Furthermore, loose or damaged hose clamps can fail to secure the hoses properly, allowing coolant to escape. Lastly, a faulty radiator cap can disrupt the pressure balance in the cooling system, contributing to leaks. By being aware of these potential issues, DIYers can take proactive steps to inspect and maintain their vehicle, ensuring it runs smoothly and efficiently. Regular checks and timely repairs can help prevent overheating and protect the engine from serious damage.
When it comes to a coolant leak in your 2017 Volvo S60, the urgency of addressing the problem cannot be overstated. Coolant plays a vital role in maintaining the engine's temperature, and a leak can quickly lead to overheating, which poses a serious risk to your engine's integrity. 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 persistent coolant leak can diminish your vehicle's performance, causing decreased fuel efficiency and further mechanical issues. By tackling a coolant leak promptly, you not only safeguard your engine from severe damage but also enhance the overall longevity and reliability of your vehicle. Therefore, if you notice any signs of a coolant leak, it is crucial to take immediate action to prevent more significant problems down the road.
