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.
To effectively diagnose a coolant leak in your 2021 Ford Escape, begin by visually inspecting the area beneath your vehicle for any signs of coolant, such as puddles or stains, which can indicate a leak. Next, examine the radiator for any visible damage or leaks, as this is a common source of coolant loss. Don’t forget to check all hoses connected to the cooling system; look for cracks, leaks, or loose connections that could compromise the system's integrity. If these initial checks do not reveal the source of the leak, consider performing a pressure test on the cooling system, which can help identify leaks that are not immediately visible. Additionally, inspect the water pump for any signs of leakage or damage, as well as the heater core, especially if you detect a sweet smell inside the cabin, which can indicate a coolant leak. Finally, monitor your coolant levels over time; a consistent drop in levels can signal a leak that needs to be addressed. By following these steps, you can systematically diagnose and address coolant leaks in your vehicle.
When dealing with coolant leaks in a 2021 Ford Escape, it's essential to understand the common culprits that may be at play. One of the primary issues is damaged or worn-out hoses, which can develop cracks or leaks over time due to heat and pressure. Additionally, a faulty radiator can be a significant source of coolant loss, as leaks can occur in the radiator itself. Another potential problem is a malfunctioning water pump, which is crucial for circulating coolant throughout the engine; if it fails, it can lead to leaks. Don't overlook the radiator cap, as a cracked or damaged cap can also allow coolant to escape from the system. Furthermore, a leaking head gasket is a serious concern, as it can permit coolant to seep into the engine or leak externally, potentially leading to severe engine damage. Lastly, corrosion within the cooling system components can gradually create leaks, making regular inspections vital. By being aware of these common causes, DIY enthusiasts can better diagnose and address coolant leaks, ensuring their Ford Escape remains in optimal condition.
Addressing a coolant leak in your 2021 Ford Escape is not just a matter of routine maintenance; it is an urgent necessity to safeguard your vehicle's engine and your safety on the road. A coolant leak can lead to severe overheating, which may warp cylinder heads or damage head gaskets, resulting in costly repairs or even complete engine failure. The risk of being stranded due to an overheated engine is a significant concern, especially if the leak goes unnoticed. Moreover, the loss of coolant can compromise the engine's ability to maintain optimal temperatures, increasing the likelihood of a breakdown. Ignoring these symptoms can lead to a cascade of problems that not only affect your vehicle's performance but also pose serious safety risks. Therefore, it is imperative to address any signs of a coolant leak immediately to ensure the reliability of your Ford Escape and to avoid the potential for dangerous situations on the road.
