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.
To effectively diagnose a coolant leak in your 2016 Chevrolet Traverse, start with a thorough visual inspection of the engine compartment. Look for any signs of coolant leakage, such as light-colored stains or residue around the radiator cap and hoses. Next, check the ground beneath your vehicle for puddles of coolant, which can appear in shades of green, orange, or pink, especially after the vehicle has been parked for a while. Pay close attention to the coolant reservoir and water pump, as these are common culprits for leaks. If you notice any visible signs of leakage, it may indicate a more serious issue that requires immediate attention. Additionally, consider the typical causes of coolant leaks, including a faulty radiator, worn hoses, or a malfunctioning water pump. By systematically assessing these areas, you can pinpoint the source of the leak and determine the best course of action for repairs.
When dealing with a coolant leak in your 2016 Chevrolet Traverse, it's essential to understand the common culprits that could be at play. One frequent issue is loose hose connections, which can occur over time due to vibrations and temperature changes, leading to coolant escaping from the system. Another significant factor to consider is a broken radiator; cracks or corrosion in the radiator can result in substantial coolant loss, necessitating immediate attention. Additionally, a failed water pump can also contribute to leaks, as it is responsible for circulating coolant throughout the engine. To effectively address these issues, start by visually inspecting the hoses and connections for any signs of looseness or wear, check the radiator for cracks, and assess the water pump for any leaks or signs of failure. Promptly identifying and rectifying these problems will help maintain your vehicle's performance and prevent further damage.
Addressing a coolant leak in your 2016 Chevrolet Traverse is not just a matter of routine maintenance; it is a critical safety concern that demands immediate attention. Coolant plays a vital role in regulating your engine's temperature, and any leak can lead to overheating, which poses a significant risk of severe engine damage. If left unchecked, the engine may run excessively hot, leading to catastrophic failures that could result in costly repairs or even total engine replacement. Moreover, a coolant leak diminishes your vehicle's cooling capacity, further exacerbating the risk of overheating. This not only affects the engine's performance but can also compromise your vehicle's overall efficiency, leading to decreased fuel economy and increased emissions. Therefore, if you notice any signs of a coolant leak, such as puddles under your vehicle or a drop in coolant levels, it is crucial to address the issue immediately to ensure your safety and the longevity of your Traverse.

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.

If a vehicle is overheating, a bad thermostat could be the problem, and a damaged thermostat housing is more likely to produce a coolant leak, either from a cracked or warped housing or a failed seal to the engine. The thermostat housing can be made of metal or plastic. And the housing can be a stand-alone part that is separate from the thermostat, or (on later model vehicles) can be integrated with the thermostat and replaced as a single unit.
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.
