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.
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.

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 diagnosing a coolant leak in your 1999 Mitsubishi Eclipse, it's essential to adopt a systematic approach that begins with simple visual inspections and progresses to more complex diagnostics. Start by conducting a thorough visual inspection of the vehicle, focusing on areas such as the radiator, hoses, and water pump for any visible signs of coolant leakage. Next, monitor the coolant levels in both the reservoir and radiator; a significant drop may indicate a leak. If these initial checks do not reveal the source, consider performing a pressure test on the cooling system, which can help pinpoint hidden leaks by pressurizing the system. Additionally, inspect the radiator and hoses for any signs of wear, such as cracks or bulges, and examine the water pump for potential leaks. Don’t overlook the heater core, as a leak here can lead to coolant entering the cabin. Lastly, be alert for any white smoke from the exhaust, which could signal coolant leaking into the combustion chamber. If you are unable to identify the leak after these steps, consulting a mechanic for a professional assessment is advisable to ensure a thorough diagnosis and repair.
When dealing with coolant leaks in a 1999 Mitsubishi Eclipse, it's essential to understand the common problems that may arise. 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 hoses transport coolant throughout the engine and can deteriorate, resulting in leaks. A faulty water pump is also a potential source of coolant loss, as it may fail to maintain proper pressure, causing leaks from the engine. Furthermore, a cracked engine block can be a serious problem, as it can lead to significant coolant leaks and engine damage. Loose or damaged hose clamps can exacerbate these issues by failing to create a proper seal, while a leaking heater core can introduce coolant leaks inside the vehicle, affecting both performance and comfort. Regular inspections and maintenance are crucial for identifying these problems early, ensuring your Eclipse runs smoothly and preventing costly repairs down the line.
Addressing a coolant leak in a 1999 Mitsubishi Eclipse is of utmost urgency due to the critical role coolant plays in maintaining engine temperature. When coolant leaks occur, they can lead to significant overheating, which not only risks immediate engine failure but can also cause long-term damage to vital components. Ignoring a coolant leak can result in a gradual loss of coolant fluid, leading to insufficient cooling and potentially catastrophic engine damage. Additionally, prolonged exposure to coolant leaks can cause corrosion of engine parts, resulting in costly repairs that could have been avoided with timely intervention. Therefore, if you notice any signs of a coolant leak, such as puddles under your vehicle or a drop in coolant levels, it is essential to address the issue immediately to ensure the safe operation of your Mitsubishi Eclipse and to prevent further complications down the line.
