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 Cruze, begin with a thorough visual inspection of the area beneath your vehicle, looking for any signs of coolant accumulation, such as puddles or stains. This initial step can often reveal obvious leaks. Next, turn your attention to the radiator, checking for any visible damage, corrosion, or leaks that could be contributing to the problem. Don’t overlook the hoses connected to the cooling system; inspect them for cracks, loose connections, or leaks that may not be immediately apparent. The water pump is another critical component to examine, as leaks or damage here can lead to significant coolant loss. If these checks do not reveal the source of the leak, consider performing a pressure test on the cooling system, which can help identify hidden leaks. Additionally, inspect the heater core and thermostat housing for any signs of leakage, as these areas can also be culprits. Finally, be alert for any unusual signs such as white smoke from the exhaust, which may indicate coolant entering the combustion chamber. By following this structured approach, you can systematically identify and address coolant leaks, ensuring your vehicle remains in optimal condition.
When dealing with coolant leaks in a 2016 Chevrolet Cruze, it's essential to understand the common problems that may arise. One of the primary culprits is a damaged radiator, which can develop cracks or corrosion over time, leading to leaks. Additionally, a faulty water pump can contribute to coolant loss, either through a leak at the pump itself or from a compromised gasket. Worn-out hoses are another frequent issue; as they age, they can become brittle and develop leaks, particularly at connection points. It's also important to check the hose clamps, as loose or damaged clamps may fail to secure hoses properly, resulting in leaks. Another potential source of coolant leaks is the heater core, which can leak coolant into the cabin if it becomes damaged. In more severe cases, a cracked engine block can be the source of the problem, although this is less common. Addressing these issues promptly is crucial to prevent overheating and further engine damage, making it advisable for DIYers to inspect these components regularly and seek professional help if necessary.
Addressing a coolant leak in your 2016 Chevrolet Cruze is not just a matter of convenience; it is a crucial step in maintaining the vehicle's health and safety. Coolant plays a vital role in regulating engine temperature, and a leak can quickly escalate into severe overheating, leading to catastrophic engine damage. If you notice any signs of a coolant leak, such as puddles under your car or a drop in coolant levels, it is imperative to act swiftly. Ignoring these symptoms can result in the engine running excessively hot, which may culminate in costly repairs or even complete engine failure. Additionally, a coolant leak can affect other vehicle components, compromising overall performance and safety. For DIY enthusiasts, addressing this issue promptly not only saves money but also ensures that your vehicle remains reliable and safe on the road. Therefore, if you suspect a coolant leak, prioritize diagnosing and repairing it to avoid further complications down the line.
