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 tackling a coolant leak in your 2023 Hyundai Tucson, start with a thorough visual inspection of the vehicle. Look for any visible signs of coolant pooling under the car or around critical components such as the radiator, hoses, and water pump. If you don’t spot any obvious leaks, the next step is to perform a pressure test on the cooling system. This involves using a hand pump to pressurize the system, which can help reveal hidden leaks that may not be immediately visible. Additionally, keep an eye on your coolant levels; a consistent drop can indicate a leak that needs addressing. Don’t forget to inspect the radiator cap, as a damaged cap can also lead to coolant loss. Examine all hoses and connections for any signs of wear, cracks, or loose fittings that could contribute to leaks. Lastly, be alert for any unusual signs such as white smoke from the exhaust or a sweet smell inside the vehicle, as these could indicate coolant entering the engine. By following these steps, you can effectively diagnose the source of a coolant leak and take the necessary actions to resolve the issue.
When dealing with coolant leaks in a 2023 Hyundai Tucson, it's essential to understand the common culprits that may be at play. One frequent issue is damaged hoses, which can develop cracks or wear over time, leading to leaks in the cooling system. Additionally, a faulty radiator is another common source of coolant loss; corrosion or physical damage can compromise its integrity. The water pump, responsible for circulating coolant, can also leak, resulting in a noticeable drop in coolant levels. Don't overlook the radiator cap, as a cracked or malfunctioning cap can allow coolant to escape. Furthermore, loose or damaged clamps that secure the hoses can contribute to leaks, as can a corroded heater core. Identifying these issues early is crucial, as neglecting a coolant leak can lead to overheating and serious engine damage. If you suspect a leak, a thorough inspection of these components can help you pinpoint the problem and determine whether a DIY fix is feasible or if professional assistance is needed.
Addressing a coolant leak in your 2023 Hyundai Tucson is not just a matter of routine maintenance; it is crucial for the safety and longevity of your vehicle. Coolant plays a vital role in regulating engine temperature, and a leak can quickly lead to overheating, which may result in severe engine damage and costly repairs. Ignoring the signs of a coolant leak can escalate the problem, causing the engine to run hot and potentially leading to catastrophic failure. Additionally, a drop in coolant levels can compromise the entire cooling system, making it essential to monitor and maintain proper fluid levels. Furthermore, a coolant leak may indicate underlying issues such as a damaged hose or a failing water pump, which, if left unaddressed, could lead to more extensive repairs. Therefore, it is imperative to act swiftly when you notice any signs of a coolant leak to ensure your Hyundai Tucson operates safely and efficiently.
