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 Fiat 500, start by observing the vehicle for common signs of a leak, such as overheating, a decrease in coolant levels, or colorful puddles beneath the car. These initial indicators can guide your inspection process. Next, focus on the radiator, as it is a frequent source of leaks; look for visible damage or fluid escaping. After that, examine the hoses and connections, which are often prone to cracks and leaks. The water pump is another critical component to check, as its gasket can fail and lead to coolant loss. Don’t overlook the thermostat, as a malfunctioning unit can also contribute to leaks. Additionally, inspect the engine block and the coolant reservoir for any signs of leakage or overflow. By systematically assessing these areas, you can pinpoint the source of the coolant leak and take appropriate action to resolve the issue.
When diagnosing a coolant leak in a 2013 Fiat 500, it's essential to consider several common problems that could be at play. One of the primary culprits is loose hose connections, which can easily be tightened to prevent leaks. Additionally, a broken radiator or a malfunctioning water pump can lead to significant coolant loss, so inspecting these components for cracks or damage is crucial. Corrosion and grime buildup can also contribute to leaks, particularly in older vehicles, making regular maintenance vital to keep the cooling system in good condition. Pay special attention to the areas where hoses connect to the engine and radiator, as these are frequent leak points. The metal pipe running across the front of the engine and the thermostat housing, especially if it has a plastic spigot, are also known to develop minor leaks. By being proactive and addressing these common issues, you can maintain your Fiat 500's performance and prevent more severe problems down the line.
Addressing a coolant leak in your 2013 Fiat 500 is not just a matter of convenience; it is a critical maintenance task that demands immediate attention. Ignoring a coolant leak can lead to severe engine overheating, which may result in catastrophic damage such as a blown head gasket or a cracked engine block. These repairs can be incredibly costly and time-consuming, making it essential to act quickly. If you find yourself frequently topping up the coolant, it’s a clear indication that there is an underlying issue that needs to be resolved rather than just managed. Additionally, a persistent leak can compromise your vehicle's reliability and performance, leaving you stranded or facing more significant mechanical failures down the line. By recognizing the signs of a coolant leak and taking prompt action, you can safeguard your engine's health and avoid the financial burden of extensive repairs. Therefore, if you notice any symptoms of a coolant leak, prioritize addressing the issue to maintain the longevity and efficiency of your Fiat 500.
