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 troubleshooting coolant leaks in your Suzuki Swift, it's crucial to adopt a systematic diagnostic approach. Begin by checking the overflow container and coolant levels, as low coolant can often lead to overheating and is a straightforward issue to resolve. Next, inspect the hoses and connections for any signs of looseness or damage, as these are common culprits for leaks. If the coolant levels are adequate, examine the radiator and the thermostat housing for any visible leaks or cracks. Pay attention to any unusual sounds, such as a squealing belt, which may indicate a failing water pump. If you notice white smoke or colorful puddles under your vehicle, these are clear indicators of a more serious problem, such as a head gasket failure. By following this methodical approach, you can effectively identify and address coolant leaks, ensuring your Suzuki Swift remains in optimal condition and preventing further complications down the line.
When addressing coolant leaks in your Suzuki Swift, it's crucial to recognize the common problems that can affect the cooling system. Loose hose connections are a frequent issue, as they can allow coolant to escape under pressure. Additionally, a damaged radiator or a malfunctioning water pump can contribute to leaks, as these components play vital roles in ensuring proper coolant circulation. The heater core is another potential source of leaks, particularly in older models, where wear and tear can lead to failures. Symptoms of a coolant leak include engine overheating, a noticeable drop in coolant levels, and colorful puddles forming beneath your vehicle. It's also essential to distinguish between coolant and water; coolant typically has a sweet smell and is available in colors like orange, green, or pink. By thoroughly inspecting the coolant reservoir, hoses, and connections, you can often pinpoint minor leaks that may be easily remedied. Taking swift action to address these issues not only enhances your vehicle's performance but also helps prevent more significant engine damage in the future.
Addressing a coolant leak in your Suzuki Swift is not just a matter of routine maintenance; it is an urgent necessity that can prevent a cascade of serious problems. Ignoring the signs of a coolant leak, such as a drop in coolant levels or unusual engine temperatures, can lead to catastrophic engine overheating, which may result in extensive and costly repairs. Moreover, coolant is toxic, posing a serious health risk to pets and children if ingested, making it imperative to act swiftly. Early detection of leaks can save you from the financial burden of major repairs and ensure your vehicle remains safe and reliable. By prioritizing the resolution of coolant leaks, you not only protect your engine from potential damage but also safeguard the well-being of those around you, reinforcing the importance of prompt action in maintaining your Suzuki Swift's performance and safety.
