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.
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 2006 Mitsubishi Raider, start by visually inspecting the area beneath your vehicle for any signs of coolant, such as puddles or stains. This initial check can help you identify the general location of the leak. Next, conduct a pressure test on the cooling system, which will allow you to pinpoint the exact source of the leak by pressurizing the system. After identifying the leak, carefully examine all hoses and connections for any signs of wear, such as cracks or bulges, and ensure that all connections are tight. Pay special attention to the radiator, as leaks or corrosion here can often be repaired, but severe damage may necessitate a replacement. Additionally, inspect the water pump and heater core for any signs of leakage, as these components are critical to the cooling system's function. If you find any damaged gaskets or seals, replace them to prevent further leaks. Once all repairs are made, refill the coolant reservoir with the appropriate mixture to ensure your vehicle operates smoothly. By following this systematic approach, you can effectively address the coolant leak and maintain the health of your Mitsubishi Raider's engine.
When dealing with coolant leaks in a 2006 Mitsubishi Raider, it's essential to understand the common problems that can arise within the cooling system. One of the primary culprits is a damaged radiator, which can develop cracks or corrosion over time, leading to leaks. Additionally, worn-out hoses are another frequent issue; these rubber components can deteriorate due to heat and age, resulting in coolant escaping. A faulty water pump is also a potential source of leaks, as it may fail or have a compromised gasket, allowing coolant to seep out. In more severe cases, a cracked engine block can lead to significant coolant loss, which requires immediate attention. Furthermore, a loose or damaged radiator cap can cause coolant to escape from the system, while a leaking heater core can contribute to internal leaks. Addressing these issues promptly is crucial to prevent overheating and protect your engine from damage, making regular inspections and maintenance vital for the longevity of your vehicle.
Addressing a coolant leak in a 2006 Mitsubishi Raider is crucial for maintaining the vehicle's health and safety. Coolant plays a vital role in regulating engine temperature; a leak can lead to overheating, which may cause severe damage to engine components, potentially resulting in costly repairs or even engine failure. Ignoring this issue not only risks the integrity of the engine but can also diminish the vehicle's performance and fuel efficiency. Furthermore, a coolant leak might indicate underlying problems within the cooling system, such as a failing water pump or a damaged radiator. By addressing the leak promptly, DIY enthusiasts can prevent these more serious issues from escalating, ensuring their vehicle remains safe and reliable on the road. Therefore, it is essential to act quickly when a coolant leak is detected to avoid significant damage and maintain optimal vehicle performance.
