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 and fix a coolant leak in your 1995 Suzuki Swift, start by identifying the nature of the leak. Check for the distinct sweet smell and color of coolant, which can help differentiate it from water. Begin your inspection with the radiator, as corrosion or physical damage is often the culprit behind leaks. Next, examine the water pump, ensuring it is functioning correctly, as a faulty pump can lead to overheating and further complications. Don’t overlook the hoses; inspect them for any signs of wear or damage, and replace any that are soft or porous. A pressure test of the cooling system can be invaluable in pinpointing hidden leaks. Additionally, be vigilant for signs of heater core leaks, such as a sweet odor inside the vehicle. If you notice unexplained coolant loss without visible leaks, consider checking for combustion gas in the coolant, which may indicate more serious issues. Once you have identified the source of the leak, you can proceed with the appropriate repairs, whether that involves replacing hoses, clamps, or other components. Addressing these leaks promptly is crucial for maintaining the efficiency and reliability of your Suzuki Swift.
When tackling a coolant leak in a 1995 Suzuki Swift, it's essential to understand the common problems that may be contributing to the issue. One of the primary culprits is often loose hose connections, which can lead to coolant escaping under pressure. Additionally, a broken radiator or a malfunctioning water pump can also result in significant leaks, making it crucial to inspect these components thoroughly. Signs of a coolant leak include overheating, a noticeable drop in coolant levels, and colorful puddles forming beneath the vehicle, which can indicate where the leak is originating. Other potential issues to consider are a faulty radiator fan or a thermostat that has failed, both of which can exacerbate cooling system problems. Addressing these leaks promptly is vital to prevent further damage to your vehicle, ensuring it runs efficiently and safely. Regular maintenance checks can help you catch these issues early, allowing for a more straightforward DIY repair process.
Addressing a coolant leak in your 1995 Suzuki Swift is not just a matter of routine maintenance; it is a pressing concern that demands immediate attention. Ignoring a coolant leak can lead to severe overheating, which poses a significant risk of catastrophic engine damage. The longer you wait, the more likely you are to encounter costly repairs that could have been easily avoided. Symptoms such as a drop in coolant levels, white smoke from the exhaust, or colorful puddles beneath your vehicle are clear indicators that something is amiss and should not be overlooked. Common causes of coolant leaks, including loose hose connections, a damaged radiator, or a failing water pump, can deteriorate further if left unaddressed, leading to more extensive and expensive repairs down the line. Therefore, it is crucial to act swiftly to diagnose and repair any coolant leaks to ensure the longevity and reliability of your vehicle.
