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 2016 Jeep Patriot, begin with a comprehensive visual inspection of the vehicle. Look for any visible signs of coolant pooling beneath the car or around essential components such as the radiator, hoses, and water pump. Next, check the coolant levels in both the reservoir and radiator; a noticeable drop may indicate a leak. If these initial checks do not reveal the source, consider performing a pressure test on the cooling system, which can help identify leaks by monitoring any pressure drops. Pay close attention to hoses and connections, as wear or looseness can lead to leaks. Additionally, inspect the radiator for signs of corrosion or damage, and examine the water pump for any signs of seepage. Don’t overlook the heater core, as leaks here can manifest as a sweet smell inside the vehicle or fogging on the windshield. If these steps do not lead to a resolution, consulting a mechanic for a professional assessment is advisable. By following this systematic diagnostic approach, you can effectively identify and address coolant leaks in your Jeep Patriot.
When tackling a coolant leak in your 2016 Jeep Patriot, it's crucial to understand the common culprits that could be at play. One of the primary issues often stems from 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 essential. Corrosion and grime buildup can also contribute to radiator leaks, highlighting the importance of regular maintenance to keep your cooling system in optimal condition. If you notice your engine temperature rising, it may indicate a small leak in the coolant system, which should be addressed immediately to avoid overheating. Furthermore, be vigilant for signs of coolant pooling under your vehicle, as this could point to a leaking radiator hose or a faulty water pump. By routinely checking your cooling system and addressing any issues promptly, you can ensure your Jeep Patriot runs smoothly and avoid costly repairs down the line.
Addressing a coolant leak in your 2016 Jeep Patriot is not just a matter of routine maintenance; it is an urgent necessity that can have serious implications for both your vehicle's performance and your safety on the road. Coolant plays a vital role in regulating engine temperature, and a leak can quickly lead to overheating, which may result in catastrophic engine damage. Ignoring this issue can escalate into costly repairs, as prolonged exposure to low coolant levels can cause the engine to seize, leaving you stranded and facing hefty bills. Moreover, a malfunctioning cooling system can compromise your vehicle's overall performance, leading to unpredictable handling and increased safety risks. Therefore, it is crucial to address any signs of a coolant leak immediately to safeguard your engine's integrity and ensure a safe driving experience.
