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 diagnosing a coolant leak in a 2000 Ford Escort, 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. If no obvious leaks are found, utilize a pressure tester to pressurize the cooling system, which can reveal leaks that may not be apparent under normal conditions. Regularly checking the coolant levels is also crucial; a consistent drop in levels can indicate a leak that needs addressing. Pay close attention to the radiator and hoses, looking for any signs of damage, such as cracks or corrosion, which could lead to leaks. Additionally, inspect the heater core, as leaks in this component can often go unnoticed but contribute to coolant loss. Finally, be alert for any unusual signs, such as white smoke from the exhaust or a sweet smell inside the vehicle, as these can indicate coolant entering the engine. By following this structured diagnostic approach, you can effectively identify and address coolant leaks in your Ford Escort.
When tackling a coolant leak in a 2000 Ford Escort, it's crucial to understand the common problems that may be at play. One frequent issue is a cracked radiator, which can develop over time due to wear and tear or physical damage. Additionally, bad radiator hoses are often a source of leaks, as they can become brittle and develop cracks or holes. Another potential culprit is the water pump, which may fail and cause coolant to escape. Lastly, a broken radiator cap can lead to pressure loss in the cooling system, resulting in leaks. To effectively address these issues, start by visually inspecting the radiator, hoses, and water pump for any signs of damage or wear. Tightening loose connections and replacing any damaged components can often resolve the leak. For minor leaks, consider using a quality coolant system sealant as a temporary fix. Regular maintenance and inspections will help you catch these problems early, ensuring your Ford Escort runs smoothly.
Addressing a coolant leak in a 2000 Ford Escort is not just a matter of routine maintenance; it is a critical safety concern that demands immediate attention. Coolant plays a vital role in regulating engine temperature, and any leak can lead to overheating, which poses a significant risk of severe engine damage. Furthermore, low coolant levels can compromise engine performance, resulting in decreased fuel efficiency and overall functionality. Ignoring a coolant leak can also lead to coolant mixing with engine oil, creating a hazardous situation that could cause internal engine damage. The potential for unexpected breakdowns on the road adds to the urgency, as this not only inconveniences the driver but also creates safety hazards for both the driver and other road users. Therefore, it is essential to address any signs of a coolant leak as soon as they are detected to ensure the vehicle operates safely and efficiently.
