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.
When diagnosing a coolant leak in your 2013 Ford Explorer, start by checking for visible signs of leakage. Look beneath the vehicle for any puddles of coolant, which can indicate where the leak is originating. Next, inspect the radiator and hoses for any cracks, holes, or loose connections, as these are common culprits for leaks due to wear over time. If no obvious leaks are found, consider performing a pressure test on the cooling system; this method can help pinpoint hidden leaks by pressurizing the system and revealing weak spots. Additionally, examine the water pump for any signs of damage or leakage, as a malfunctioning pump can contribute to coolant loss. Don’t forget to check the heater core, as leaks here can lead to coolant entering the vehicle's interior. Lastly, inspect the head gasket for any signs of coolant mixing with oil or exhaust gases, which could indicate a more serious issue. By following these steps, you can effectively diagnose the source of a coolant leak and take the necessary actions to address it.
When dealing with coolant leaks in a 2013 Ford Explorer, 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 another frequent issue; over time, the rubber can degrade, resulting in cracks or holes that allow coolant to escape. The water pump, responsible for circulating coolant throughout the engine, can also fail, leading to leaks if it malfunctions. Furthermore, loose or damaged hose clamps may fail to create a proper seal, exacerbating the problem. In more severe cases, a cracked engine block can cause coolant to leak, which requires immediate attention from a mechanic. Lastly, a leaking heater core can result in coolant pooling inside the vehicle, often noticeable by a sweet smell or wet carpets. Addressing these issues promptly is essential to prevent overheating and potential engine damage, making it vital for DIYers to be aware of these common causes when troubleshooting coolant leaks.
Addressing a coolant leak in your 2013 Ford Explorer is not just a matter of routine maintenance; it is an urgent necessity to safeguard your vehicle's engine and ensure your safety on the road. Ignoring a coolant leak can lead to severe overheating, which poses a significant risk of engine damage that could result in costly repairs or even total engine failure. The coolant system plays a vital role in regulating engine temperature, and any disruption can lead to catastrophic consequences. Moreover, a malfunctioning coolant system can compromise your vehicle's performance and reliability, increasing the likelihood of breakdowns. Therefore, it is imperative to act swiftly at the first sign of a coolant leak, whether it involves tightening hoses, replacing damaged components, or ensuring the correct coolant levels. By addressing this issue promptly, you not only protect your investment but also enhance your safety and peace of mind while driving.
