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.
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 a Mitsubishi Mighty Max, it's essential to adopt a systematic diagnostic approach. Begin by visually inspecting the engine bay for any obvious signs of leaks, such as puddles or wet spots around hoses and connections. Check the tightness of hose clamps and ensure that all connections are secure, as loose fittings are often the simplest culprits. If no leaks are visible, utilize a system pressure tester to pressurize the cooling system while the engine is cold; this can help identify leaks that may not be apparent under normal conditions. Pay close attention to the water pump and thermostat, as these components are common failure points. If the leak persists, inspect the coolant pipes for rust or corrosion, which can develop over time. By methodically addressing these areas, you can effectively diagnose and resolve coolant leaks, ensuring your Mitsubishi Mighty Max runs smoothly and efficiently.
When tackling coolant leaks in a Mitsubishi Mighty Max, it's essential to understand the common problems that can arise within the cooling system. One of the most frequent issues is loose hose connections, which can lead to significant fluid loss if not addressed promptly. Additionally, a broken radiator or a failed water pump can also contribute to leaks, often requiring immediate repair or replacement to prevent engine overheating. Leaking radiator hoses are another common culprit, as they can deteriorate over time due to wear and exposure to heat. It's also important to consider the condition of the thermostat housing, intake manifold gasket, and heater core, as these components can develop leaks that may not be immediately visible. Lastly, a failing head gasket can present more complex symptoms, often affecting both engine oil and coolant passages, making it crucial to monitor for any unusual changes in engine performance. By being aware of these potential issues, you can more effectively diagnose and address coolant leaks, ensuring your Mitsubishi Mighty Max remains in optimal working condition.
Addressing a coolant leak in your Mitsubishi Mighty Max is not just a matter of routine maintenance; it is an urgent necessity that can have serious implications for both your vehicle's health and your safety. When coolant leaks occur, they can lead to overheating, which poses a direct threat to the engine's integrity. An overheated engine can suffer from warped components or even complete failure, resulting in costly repairs that could have been easily avoided with timely intervention. Moreover, a leaking coolant system can compromise your vehicle's performance, leading to decreased efficiency and reliability on the road. This situation can escalate into safety hazards, such as steam or smoke emanating from the engine bay, which not only endangers you but also other drivers. By addressing a coolant leak promptly, you not only safeguard your engine from severe damage but also ensure a safer driving experience, ultimately saving you from the financial burden of extensive repairs. Therefore, recognizing and acting on the signs of a coolant leak is crucial for maintaining the longevity and performance of your Mitsubishi Mighty Max.
