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 Volt, begin with a comprehensive visual inspection of the coolant system components, including the coolant reservoir, water pump, hoses, radiator, and heater core. Look for any visible signs of leakage, such as damp spots or coolant residue, which can indicate a problem. Pay special attention to the area around the radiator cap and hoses for light-colored stains, as these may suggest a slow leak. Next, check the ground beneath your vehicle for any puddles of coolant, which typically appear in colors like green, orange, or pink, especially after the car has been parked for a while. Additionally, monitor your dashboard for any coolant warning lights, as their activation can signal a leak that needs immediate attention. Lastly, inspect critical components such as hoses, radiator caps, and head gaskets for signs of wear or damage. By following this methodical approach, you can effectively pinpoint the source of the leak and take the necessary steps to address it, helping to prevent further damage to your vehicle.
When dealing with a coolant leak in a 2016 Chevrolet Volt, it's crucial to understand the common problems that may be at play. One of the primary culprits is loose hose connections, which can occur over time due to vibrations and temperature changes. Inspecting these connections for tightness and signs of wear can often reveal the source of the leak. Another frequent issue is a broken radiator, which can develop cracks or holes from corrosion or physical damage, leading to significant coolant loss. Lastly, a failed water pump can also contribute to leaks, as it is responsible for circulating coolant throughout the engine. If you notice any signs of coolant pooling under your vehicle or a drop in coolant levels, addressing these areas promptly can help maintain your Volt's cooling system and prevent further damage.
Addressing a coolant leak in your 2016 Chevrolet Volt is an urgent matter that should not be overlooked. Ignoring the signs of a coolant leak, such as puddles of bright green or orange fluid, can lead to severe engine damage and costly repairs down the line. The cooling system plays a critical role in maintaining the engine's temperature, and any disruption can result in overheating, which poses significant safety risks. Additionally, a persistent leak can lead to a decrease in engine efficiency, further compounding the problem. Therefore, it is essential to act quickly and identify the source of the leak to prevent further complications and ensure the longevity of your vehicle. Taking prompt action not only safeguards your car's performance but also protects your investment in the long run.
