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.
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.
When tackling a coolant leak in your Buick Reatta, it's essential to adopt a methodical diagnostic approach. Start by visually inspecting the area around the engine and under the vehicle for any signs of coolant puddles or stains, which can indicate the leak's location. Check the coolant reservoir and radiator for proper fluid levels, as low coolant can lead to overheating. Next, examine the hoses and connections for cracks or wear, as these are common culprits for leaks. If the initial checks do not reveal the source, consider inspecting the radiator cap and the water pump, as a faulty cap can lead to pressure loss and leaks. If you still cannot identify the issue, look for more complex problems such as a blown head gasket or a damaged heater core, which may require more extensive repairs. By following this structured approach, you can effectively diagnose the problem and take the necessary steps to fix the leak, ensuring your vehicle remains in optimal condition.
When diagnosing and fixing coolant leaks in a Buick Reatta, it's essential to be aware of common problems that may arise within the cooling system. One frequent issue is the deterioration of rubber hoses, which can become brittle and develop cracks over time, leading to leaks. Additionally, the radiator itself may corrode or sustain damage from road debris, resulting in coolant loss. Another potential culprit is the water pump, which can fail due to wear and tear, causing coolant to leak from the weep hole. It's also important to check the radiator cap, as a faulty cap can fail to maintain proper pressure, allowing coolant to escape. Lastly, if you notice a milky substance in the oil, it could indicate a blown head gasket, which requires immediate attention to prevent severe engine damage. By understanding these common problems, you can more effectively diagnose and address coolant leaks in your Buick Reatta, ensuring your vehicle remains in optimal condition.
Addressing a coolant leak in your Buick Reatta is not just a matter of routine maintenance; it is a critical step in safeguarding your vehicle's performance and longevity. Ignoring a coolant leak can lead to severe engine overheating, which may cause irreversible damage to vital components, resulting in costly repairs that could have been easily avoided. Additionally, a loss of coolant diminishes the engine's cooling efficiency, potentially affecting its overall performance and lifespan. Beyond mechanical concerns, coolant leaks can create hazardous conditions, such as slippery puddles that increase the risk of accidents. The sweet smell of leaking coolant also poses a danger to pets and wildlife, making it essential to act swiftly. Furthermore, a coolant leak may indicate more serious underlying issues, such as a blown head gasket, which can escalate into significant engine damage if not addressed promptly. Therefore, for the safety of both the driver and the vehicle, it is imperative to tackle coolant leaks immediately to prevent further complications and ensure a smooth driving experience.
