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 2016 Chevrolet SS, start with a thorough visual inspection of your vehicle. Begin by checking for any puddles of coolant beneath the car, as this can provide immediate clues about the leak's location. Next, inspect the radiator for signs of corrosion or wet spots, which may indicate a leak. Pay close attention to the hoses and connections, looking for cracks or bulges that could lead to coolant loss. If these initial checks do not reveal the source of the leak, consider performing a pressure test on the cooling system, as this can help uncover hidden leaks. Additionally, examine the water pump for any signs of leakage, and don't forget to check the heater core, especially if you notice a sweet smell inside the cabin or fogging on the windshield. By following this diagnostic approach, you can systematically identify and address the coolant leak, ensuring your vehicle remains in optimal condition.
When dealing with coolant leaks in a 2016 Chevrolet SS, it's essential to recognize the common problems that may arise. A damaged radiator is often a primary culprit, as corrosion or physical damage can lead to significant leaks. Additionally, a faulty water pump can contribute to coolant loss, as it is responsible for circulating coolant throughout the engine. Over time, hoses can wear out, developing cracks or leaks that compromise the cooling system's integrity. It's also crucial to check the hose clamps; if they are loose or damaged, they may fail to create a proper seal, resulting in leaks. Another potential issue is a leaking heater core, which can cause coolant to leak inside the vehicle or under the hood. In more severe cases, a cracked engine block may be the source of the problem, leading to substantial coolant loss. Addressing these issues promptly is vital to prevent overheating and potential engine damage, making it important for DIYers to be vigilant and proactive in their maintenance efforts.
Addressing a coolant leak in your 2016 Chevrolet SS is not just a matter of routine maintenance; it is an urgent necessity that can significantly impact both the performance of your vehicle and your safety on the road. Coolant is essential for regulating engine temperature, and even a small leak can lead to overheating, which poses a serious risk of damaging vital engine components such as cylinder heads and gaskets. Ignoring this issue can escalate into costly repairs, including the potential for a cracked engine block. Moreover, a severe coolant leak can create immediate safety hazards, including the risk of engine failure while driving or even a fire. For DIY enthusiasts, it is crucial to regularly check your coolant levels and address any leaks as soon as they are detected. By taking swift action, you not only protect your investment but also ensure a safe and reliable driving experience.
