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.

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.
When diagnosing a coolant leak in your 2012 Chevrolet Camaro, it's essential to adopt a systematic approach that begins with the most straightforward checks before progressing to more complex diagnostics. Start by inspecting the area beneath your vehicle for any puddles of coolant, which can be identified by their distinct colors—green, orange, or pink. This initial observation can provide immediate clues about the leak's location. Next, examine the radiator for any visible signs of damage or leaks, such as wet spots or corrosion, which may indicate a failure in the cooling system. Following this, inspect all hoses and connections for cracks or bulges, ensuring that any loose fittings are tightened and damaged hoses are replaced. If these checks do not reveal the source of the leak, consider performing a pressure test on the cooling system, as this can help uncover leaks that are not immediately visible. Additionally, pay close attention to the water pump and heater core; any signs of leakage or unusual smells inside the vehicle may point to issues in these areas. By methodically following these steps, you can effectively diagnose the coolant leak and determine the necessary repairs for your Camaro.
When dealing with coolant leaks in a 2012 Chevrolet Camaro, 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, worn-out hoses are another frequent issue; these hoses transport coolant throughout the engine and can deteriorate, resulting in leaks. A faulty water pump can also be a source of coolant loss, as it may fail to maintain proper circulation, causing leaks from the engine. Furthermore, loose or damaged hose clamps can prevent a secure seal, allowing coolant to escape. In more severe cases, a cracked engine block or a leaking heater core can lead to significant coolant loss. Lastly, don’t overlook the radiator cap and coolant reservoir, as a faulty cap can disrupt system pressure and a damaged reservoir can directly leak coolant. Addressing these issues promptly is crucial to avoid overheating and potential engine damage, making regular inspections and maintenance vital for any Camaro owner.
Addressing a coolant leak in a 2012 Chevrolet Camaro is of utmost urgency due to the significant risks associated with neglecting this issue. Coolant plays a vital role in maintaining the engine's temperature, and a leak can lead to overheating, which may result in severe engine damage or even complete failure. Ignoring a coolant leak not only compromises the engine's efficiency but can also lead to costly repairs down the line, as the vehicle may suffer from performance issues and increased wear and tear. Furthermore, a coolant leak could indicate underlying problems within the cooling system, such as a damaged radiator or a failing water pump, which require immediate attention to prevent further complications. Therefore, it is crucial for DIY enthusiasts to inspect and repair any coolant leaks as soon as they are detected, ensuring the safety and longevity of their vehicle.
