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 2001 Suzuki Esteem, start by visually inspecting the area beneath your vehicle for any puddles or wet spots, as these can indicate the presence of coolant. Next, monitor the coolant levels in your reservoir; a consistent drop in levels may suggest a leak. Pay close attention to the hoses and water pump, as these are common culprits for leaks in this model. If the initial checks do not reveal the source, consider performing a coolant system pressure test, which can help identify the leak's location by observing any pressure drops in the system. Additionally, inspect for signs of corrosion or rust around the radiator and hoses, as these can signal potential leak points. If you find it challenging to pinpoint the issue or if the repairs seem daunting, it’s wise to consult a professional mechanic for a comprehensive diagnosis and repair. By following this structured approach, you can efficiently identify and address coolant leaks, ensuring your vehicle remains in optimal condition.
When dealing with coolant leaks in a 2001 Suzuki Esteem, it's crucial to understand the common problems that may arise. One of the primary culprits is faulty hoses, which can develop cracks or become loose over time, allowing coolant to escape. Additionally, issues with the water pump can lead to leaks, as a malfunctioning pump may not circulate coolant properly, resulting in pressure build-up and subsequent leaks. Corrosion within the radiator is another significant concern; as the radiator ages, it can develop rust and holes that compromise its integrity. Lastly, wear and tear on the sealing gasket between the tank and the radiator can create gaps, leading to leaks. By recognizing these potential issues, DIY enthusiasts can take proactive steps to inspect and repair their vehicle, ultimately preventing overheating and more severe engine damage.
Addressing a coolant leak in your 2001 Suzuki Esteem is not just a matter of convenience; it is a critical maintenance task that demands immediate attention. Ignoring even a small leak can lead to a significant loss of coolant, which may cause your engine to overheat. This overheating can result in severe engine damage, including warped cylinder heads or a blown head gasket, both of which can be costly to repair. Furthermore, if the leak is substantial, it may necessitate a complete radiator replacement, which is a more extensive and expensive fix. Regularly monitoring your vehicle's cooling system is essential for maintaining engine health and performance. By promptly addressing any signs of a coolant leak, you not only safeguard your engine from potential harm but also ensure the longevity and reliability of your vehicle. Therefore, if you notice any signs of a coolant leak, take action immediately to prevent further complications and keep your Suzuki Esteem running smoothly.
