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.
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 1997 Ford E-150 Econoline, start with a thorough visual inspection of the vehicle. Look for any visible signs of coolant pooling under the vehicle or stains around critical areas such as the radiator, hoses, and water pump. If you don’t spot any obvious leaks, the next step is to perform a pressure test using a cooling system pressure tester. This tool will help you identify the source of the leak by pressurizing the system and revealing any weak points where coolant may escape. Additionally, inspect the radiator cap for wear, as a damaged cap can lead to leaks. Pay close attention to the hoses connected to the cooling system; cracks or bulges can indicate potential failure points. Don’t forget to check the water pump for leaks, particularly around the weep hole or gasket, as these are common culprits. Lastly, examine the heater core for any signs of leakage, which can manifest as coolant inside the vehicle or fogged windows. Throughout this process, monitor the coolant level in the reservoir; a significant drop without visible leaks may suggest an internal issue, such as a blown head gasket. By following these steps, you can systematically diagnose and address coolant leaks, ensuring your vehicle remains in optimal condition.
When dealing with coolant leaks in a 1997 Ford E-150 Econoline, it's crucial to understand the common problems that may arise. A damaged radiator is often a primary culprit, as corrosion or physical damage can lead to significant leaks. Additionally, worn-out hoses are frequent offenders; over time, the rubber can degrade, resulting in cracks or holes that allow coolant to escape. Another potential issue is a faulty water pump, which can leak coolant if its seals are compromised. It's also important to check the hose clamps; if they are loose or damaged, they may fail to create a proper seal, leading to leaks. In more severe cases, a cracked engine block can be the source of coolant loss, which requires immediate attention. Lastly, a leaking heater core can cause coolant to seep into the vehicle's interior, indicating a need for repair. Addressing these issues promptly is essential to prevent overheating and protect the engine from damage, making it vital for DIYers to be aware of these common causes when troubleshooting coolant leaks.
Addressing a coolant leak in your 1997 Ford E-150 Econoline 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 a rapid loss of coolant fluid, resulting in dangerously low levels that can cause the engine to overheat. Overheating can lead to catastrophic engine damage, which is not only costly to repair but can also leave you stranded on the road. Furthermore, neglecting a coolant leak can lead to corrosion within the cooling system, exacerbating the problem and leading to more extensive repairs down the line. By addressing the leak promptly, you not only safeguard your engine's health but also ensure the safe and efficient operation of your vehicle, ultimately saving you time and money. Therefore, if you notice any signs of a coolant leak, it is imperative to act quickly to prevent further complications.
