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 1995 Hyundai Elantra, begin by inspecting the coolant levels when the engine is cool. This initial step helps you determine if there is a significant loss of coolant. Next, focus on common leak locations such as the thermostat housing, radiator, water pump, and head gasket, as these areas are often prone to leaks. Pay attention to any symptoms like low coolant levels, engine overheating, or visible puddles under the vehicle, as these can provide crucial clues about the leak's source. If you suspect a leak but cannot locate it, using a pressure tester can help identify issues within the cooling system. Additionally, look for any drips on the ground, which can further assist in pinpointing the leak's location. If necessary, top up the coolant to maintain proper levels, and monitor the coolant regularly; frequent top-ups may indicate a more serious problem that warrants a professional inspection. By following this structured approach, you can efficiently diagnose and address coolant leaks, ensuring your vehicle remains in optimal condition.
When it comes to diagnosing coolant leaks in a 1995 Hyundai Elantra, understanding the common problems can save you time and money. One of the primary culprits is often loose hose connections, which can easily be tightened to prevent leaks. Additionally, a broken radiator or a malfunctioning water pump can lead to significant coolant loss, so inspecting these components is essential. Over time, the age and wear of hoses and seals can cause them to deteriorate, making them more susceptible to leaks. Regular maintenance, including timely coolant replacement, is crucial as it helps prevent radiator corrosion, a common issue in older vehicles. Being vigilant for early signs of a coolant leak, such as engine overheating, a noticeable decrease in coolant levels, or colorful puddles forming under your car, can help you address problems before they escalate. By staying proactive about these common issues, you can ensure your Hyundai Elantra remains in optimal condition and avoid more costly repairs down the line.
Addressing a coolant leak in a 1995 Hyundai Elantra is of utmost importance due to the serious risks associated with engine overheating. If left unattended, a coolant leak can lead to catastrophic engine damage, which can be costly and time-consuming to repair. Early detection is key; common signs such as a decrease in coolant levels, white smoke from the exhaust, or colorful puddles under the vehicle should not be ignored. These symptoms indicate that the engine is at risk of overheating, which can result in internal damage if coolant leaks into the combustion chamber or if the engine runs dry. By promptly addressing a coolant leak, you not only safeguard your vehicle's performance but also prevent more extensive and expensive repairs down the line. Therefore, if you suspect a coolant leak, it is crucial to take immediate action to ensure the longevity and reliability of your Hyundai Elantra.
