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.
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.
To effectively diagnose a coolant leak in your 1992 Mercury Capri, 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, proceed to perform a pressure test on the cooling system, which can help reveal hidden leaks by pressurizing the system and allowing you to pinpoint the source. Next, inspect the radiator cap, as a damaged cap can lead to coolant loss. Pay close attention to the hoses connected to the cooling system; any cracks or bulges can indicate potential leaks. Additionally, examine the water pump for signs of leakage, as this is a common culprit. Don’t forget to check the heater core, especially if you notice coolant inside the cabin, which could signal a leak. Finally, monitor the coolant level in the reservoir regularly; a significant drop without visible leaks may suggest an internal issue. By following this structured approach, you can efficiently diagnose and address coolant leaks, ensuring your Mercury Capri remains in optimal condition.
When dealing with coolant leaks in a 1992 Mercury Capri, it's essential to understand the common problems that may arise. One of the primary culprits is worn-out hoses, which can develop cracks over time due to heat and pressure, leading to leaks. Additionally, a faulty radiator can contribute to coolant loss, as corrosion or physical damage can create openings for coolant to escape. The water pump, responsible for circulating coolant, can also be a source of leaks if it becomes damaged or worn. Another often-overlooked issue is a cracked radiator cap, which can fail to maintain proper pressure in the cooling system, resulting in coolant leakage. Furthermore, loose or damaged hose clamps may prevent hoses from sealing correctly, allowing coolant to seep out. Lastly, a leak directly in the radiator itself can be a significant concern. Addressing these issues promptly is crucial to avoid overheating and potential engine damage, making regular inspections and maintenance vital for the longevity of your vehicle.
Addressing a coolant leak in your 1992 Mercury Capri is not just a matter of routine maintenance; it is an urgent necessity to safeguard your engine and ensure your safety on the road. A coolant leak can lead to severe overheating, which poses a significant risk of damaging vital engine components such as cylinder heads and head gaskets. If these parts fail, the cost of repairs can escalate quickly, potentially leading to complete engine failure. Moreover, a leaking coolant system can create hazardous driving conditions, as spilled coolant can make roads slippery, increasing the likelihood of accidents. Ignoring this issue not only jeopardizes your vehicle's performance but also puts you and other road users at risk. Therefore, it is imperative to address any signs of a coolant leak immediately to prevent costly repairs and ensure a safe driving experience.
