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.

If a vehicle is overheating, a bad thermostat could be the problem, and a damaged thermostat housing is more likely to produce a coolant leak, either from a cracked or warped housing or a failed seal to the engine. The thermostat housing can be made of metal or plastic. And the housing can be a stand-alone part that is separate from the thermostat, or (on later model vehicles) can be integrated with the thermostat and replaced as a single unit.
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 2017 Ford Police Interceptor Sedan, start with a thorough visual inspection. Open the hood and look for any visible signs of coolant, such as puddles or white residue around the radiator, hoses, and water pump. This initial step can often reveal obvious leaks. Next, consider using a cooling system pressure tester, which allows you to pressurize the system and pinpoint the source of the leak more accurately. Pay special attention to the radiator cap, as a damaged cap can lead to leaks and overheating; ensure it is in good condition. Inspect all coolant hoses for any signs of wear, such as cracks or bulges, since these are common culprits for leaks. Additionally, examine the water pump for any leaks or corrosion, as a malfunctioning pump can also contribute to coolant loss. Finally, be alert for any steam or a sweet smell while driving, as these can be indicators of a coolant leak. By following this structured approach, you can efficiently diagnose and address coolant leaks, helping to maintain your vehicle's performance and prevent further damage.
When dealing with coolant leaks in a 2017 Ford Police Interceptor Sedan, it's essential to understand the common culprits that may be at play. One of the primary causes is damaged hoses, which can develop wear and tear over time, leading to leaks. Additionally, a faulty radiator, whether due to cracks or other damage, can also be a significant source of coolant loss. It's important to check the radiator cap as well; if it's loose or damaged, it can allow coolant to escape. Another common issue is a leaking water pump, which can often go unnoticed until it causes more severe problems. Corrosion in the heater core is another potential issue that can lead to leaks, as is a cracked engine block, which can be a more serious concern. Regular inspections and maintenance are crucial in identifying these problems early, allowing DIY enthusiasts to take action before they escalate into more significant engine damage.
Addressing a coolant leak in a 2017 Ford Police Interceptor Sedan is of utmost urgency due to the significant risks associated with engine overheating. Coolant plays a vital role in regulating engine temperature; a leak can lead to insufficient coolant levels, resulting in the engine running hotter than normal. This overheating can cause severe damage, including warped cylinder heads or even complete engine failure, which can be costly to repair. Furthermore, neglecting a coolant leak not only jeopardizes the engine's integrity but also diminishes the vehicle's overall performance and efficiency. For those looking to DIY, it is crucial to inspect for leaks immediately and take corrective action, whether that involves patching the leak or replacing damaged components. By addressing the issue promptly, you can safeguard your vehicle's reliability and longevity, ensuring it remains safe and efficient on the road.
