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.
When diagnosing a coolant leak in your 1999 Dodge Viper, it's essential to adopt a systematic approach that begins with simple visual inspections and progresses to more complex diagnostics. Start by conducting a thorough visual inspection of the vehicle, focusing on areas such as the radiator, hoses, and water pump for any visible signs of coolant leakage. Next, check the coolant levels in both the reservoir and radiator; a significant drop may indicate a leak. If these initial checks do not reveal the source, consider performing a pressure test on the cooling system, which can help simulate operating conditions and pinpoint leaks more accurately. Additionally, inspect the radiator and hoses for any signs of damage, such as cracks or corrosion, and examine the water pump for leaks or wear. Don’t overlook the heater core, as leaks here can lead to coolant entering the cabin. Finally, be alert for any unusual signs, such as white smoke from the exhaust or a sweet smell inside the vehicle, which could suggest coolant is leaking into the engine. By following this structured diagnostic approach, you can effectively identify and address the coolant leak in your Viper.
When dealing with coolant leaks in a 1999 Dodge Viper, it's essential to understand the common problems that may arise. A faulty radiator is often a primary culprit, as corrosion or damage can lead to significant leaks. Additionally, worn-out hoses are another frequent issue; over time, these hoses can deteriorate, resulting in cracks or holes that allow coolant to escape. It's also important to check the hose clamps, as loose or damaged clamps may fail to secure the hoses properly, contributing to leaks. In more severe cases, a cracked engine block can be the source of coolant loss, which requires immediate attention. Another potential problem is a leaking water pump, which is crucial for circulating coolant throughout the engine. Lastly, a faulty radiator cap can disrupt the pressure balance in the cooling system, leading to leaks. By being aware of these common causes, DIY enthusiasts can take proactive steps to inspect and maintain their Viper, ensuring optimal performance and preventing overheating.
Addressing a coolant leak in a 1999 Dodge Viper is of utmost importance due to the serious risks associated with neglecting this issue. Coolant plays a critical role in regulating engine temperature; without it, the engine is at a high risk of overheating, which can lead to catastrophic damage. If a leak is ignored, the loss of coolant can result in insufficient cooling, ultimately jeopardizing the engine's integrity and leading to costly repairs. Furthermore, a coolant leak can adversely affect the vehicle's overall performance, making it essential to act quickly to maintain optimal functionality and safety. By promptly addressing a coolant leak, you not only protect your engine from potential harm but also ensure a reliable driving experience, making it clear that timely intervention is crucial for the longevity and performance of your Viper.
