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 2013 Ford Focus, start by visually inspecting the area beneath your vehicle for any puddles of coolant, as this is often the most straightforward indication of a leak. Next, examine the hoses connected to the radiator, looking for any signs of cracks, loose connections, or leaks that could be contributing to the problem. Don’t overlook the radiator itself; check for corrosion or any visible leaks that may be present. If these initial checks do not reveal the source of the leak, consider performing a pressure test on the cooling system, which can help pinpoint hidden leaks. Additionally, inspect the water pump for any signs of damage or leakage, as this component is crucial for maintaining proper coolant circulation. Pay attention to the heater core as well, especially if you detect a sweet smell inside the cabin, which can indicate a leak. Throughout this process, monitor your coolant levels closely; a consistent drop in coolant can signal a leak that needs addressing. If you find yourself unable to identify the source after these steps, it may be wise to consult a mechanic for a professional assessment and repair. This methodical approach not only simplifies the diagnosis but also empowers you to tackle the issue with confidence.
When dealing with coolant leaks in a 2013 Ford Focus, it's essential to understand the common culprits that may be at play. One of the primary sources of leaks can be a damaged radiator, which may develop cracks or corrosion over time, leading to coolant escaping. Additionally, worn-out hoses are another frequent issue; these rubber components can deteriorate due to heat and age, resulting in leaks that can be difficult to spot. The water pump, responsible for circulating coolant throughout the engine, can also fail, causing leaks if it becomes faulty. Furthermore, loose or damaged hose clamps can prevent a proper seal, allowing coolant to seep out. In more severe cases, a cracked engine block can lead to significant leaks, while a leaking heater core can also contribute to coolant loss, often accompanied by a sweet smell inside the vehicle. Addressing these issues promptly is crucial to avoid overheating and potential engine damage, making regular inspections and maintenance vital for any DIY enthusiast looking to keep their Ford Focus in optimal condition.
Addressing a coolant leak in your 2013 Ford Focus is not just a matter of convenience; it is a crucial step in maintaining the health and safety of your vehicle. Ignoring a coolant leak can lead to severe engine overheating, which may result in catastrophic engine damage that could require expensive repairs or even a complete engine replacement. Additionally, a loss of coolant can compromise the engine's cooling efficiency, leading to performance issues and reduced reliability. The longer you allow a coolant leak to persist, the more likely you are to face escalating repair costs, as continued operation with low coolant levels can exacerbate the problem. Therefore, it is essential to act swiftly when you notice any signs of a coolant leak to safeguard your vehicle's performance and longevity.
