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 2014 Dodge Journey, start with a thorough visual inspection. Park your vehicle on a clean, dry surface and allow it to cool completely. Look for any colored puddles beneath the car, as these can indicate the presence of coolant, which may appear blue-green, pink, orange, or lime-green. Next, check your dashboard for any warning lights, such as the coolant warning or 'check engine' light, which may signal coolant-related problems. Open the hood and use your sense of smell to detect any sweet odors associated with coolant leaks, while also inspecting the coolant reservoir for proper levels and secure cap placement. If the leak remains elusive, consider using a cooling system pressure testing kit to identify hidden leaks; ensure the engine is cold for safety. Additionally, employing a UV dye test can help pinpoint leaks that are not immediately visible. Pay special attention to common problem areas, such as the heater hose's plastic T-connector and the connections between coolant lines. If you encounter difficulties or the leak is in a hard-to-reach area, seeking professional assistance is advisable to ensure a thorough diagnosis and repair.
When dealing with coolant leaks in a 2014 Dodge Journey, it's essential to understand the common problems that may arise. One of the first areas to inspect is the radiator cap, as a faulty cap can lead to a drop in system pressure, resulting in leaks. Additionally, the radiator itself may develop pinhole leaks, which can be identified by checking for coolant around the radiator and front pulleys. Another frequent culprit is the coolant hoses, particularly the heater hose located at the rear of the engine compartment, where the plastic T-connector is known to fail. While the water pump can also be a source of leaks, its replacement is more complex and may not be suitable for DIY repairs. Internal leaks, such as those involving the head gasket or engine block, can be serious and often require professional attention. Regular maintenance, including flushing the cooling system, can help prevent excessive corrosion and contamination, which are also contributors to leaks. By systematically checking these components, DIYers can effectively diagnose and address coolant leaks in their Dodge Journey.
Addressing a coolant leak in a 2014 Dodge Journey is of utmost urgency due to the severe consequences that can arise from neglecting this issue. A coolant leak can lead to engine overheating, which poses a significant risk of catastrophic damage, including warped cylinder heads and cracked engine blocks. These repairs can be both costly and time-consuming, making it essential to act quickly. Moreover, driving with a coolant leak is inherently dangerous; an overheating engine can cause the vehicle to stall unexpectedly, increasing the risk of accidents. Additionally, steam from the cooling system can impair visibility, further endangering the driver and others on the road. Ignoring a coolant leak can also lead to contamination within the cooling system, potentially resulting in internal leaks that require extensive repairs, such as head gasket replacements. Regular maintenance and prompt attention to coolant leaks are vital for the longevity of the vehicle, as neglecting these issues can lead to more frequent and expensive repairs over time. Therefore, it is crucial to address any signs of a coolant leak immediately to safeguard both the vehicle's performance and the safety of its occupants.
