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 faced with coolant leaks in your Hyundai Veloster, a systematic diagnostic approach can help you identify and resolve the issue efficiently. Start by ensuring the engine is cool before inspecting the radiator and surrounding components for visible signs of leakage. Common culprits include loose hose connections, a damaged radiator, or a malfunctioning water pump, so pay close attention to these areas. If the leak isn't immediately apparent, consider using a pressure tester, which can be rented from most auto parts stores. This tool pressurizes the cooling system, making it easier to spot leaks that may not be visible under normal conditions. As you inspect, look for any splits in hoses or cracks in fittings, and check for debris that might be obstructing a proper seal. By following this methodical approach, you can effectively diagnose and potentially fix coolant leaks, saving both time and money while enhancing your DIY skills.
When it comes to identifying coolant leaks in your Hyundai Veloster, understanding the common problems associated with the cooling system can significantly aid in your diagnosis. One prevalent issue is the deterioration of hoses, which can develop cracks or splits over time due to heat and wear, leading to leaks. Additionally, the radiator itself may suffer from corrosion or damage, resulting in coolant escaping from small holes. Another frequent culprit is the water pump, which can fail and cause coolant to leak from its seals. It's also essential to consider the possibility of a blown head gasket, which can lead to coolant mixing with engine oil or leaking externally. By being aware of these common failure modes, you can more effectively troubleshoot and address coolant leaks, ensuring your Veloster remains in optimal condition.
Addressing a coolant leak in your Hyundai Veloster is not just a matter of routine maintenance; it is an urgent necessity that can have serious implications for both your vehicle's performance and your safety. Ignoring a coolant leak can lead to overheating, which may cause catastrophic engine damage and costly repairs. The coolant system plays a vital role in regulating engine temperature, and a leak can quickly deplete coolant levels, leaving your engine vulnerable to extreme heat. This not only jeopardizes the reliability of your vehicle but also poses significant safety risks, as an overheated engine can lead to sudden breakdowns on the road. Furthermore, the common causes of coolant leaks, such as corrosion and physical damage, can escalate if not addressed promptly, leading to more extensive repairs. Regularly checking your coolant levels and being vigilant for signs of leaks can help you catch issues early, preventing further damage and ensuring your Hyundai Veloster remains safe and efficient on the road.
