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:

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.
When troubleshooting coolant leaks in your Dodge Omni, start with a methodical diagnostic approach that prioritizes the most accessible components. Begin by inspecting the hoses for any visible signs of wear, such as cracks or leaks, as these are often the easiest to identify and fix. Next, examine the radiator for any signs of corrosion or leaks, which can be a common culprit in coolant loss. If the hoses and radiator appear intact, turn your attention to the water pump, as a malfunction here can lead to significant leaks. Additionally, check the coolant feed line for any damage or loose fittings that could be contributing to the problem. While these components are typically the first to check, don’t overlook other potential issues like a faulty thermostat or radiator cap, which can also lead to coolant loss. If you notice a drop in coolant levels without visible leaks, it’s wise to monitor the situation closely and consider professional assistance if necessary. Addressing these leaks promptly is essential to prevent overheating and ensure the longevity of your vehicle. By following this structured approach, you can effectively diagnose and resolve coolant leaks in your Dodge Omni, maintaining its performance and reliability.
When tackling coolant leaks in a Dodge Omni, it's essential to understand the common problems that can arise within the cooling system. Start by inspecting the vehicle for visible signs of leaks, such as puddles of coolant underneath, which can indicate issues with components like the radiator or hoses. Pay close attention to the radiator hoses, as they are often the culprits behind leaks due to wear and tear. Additionally, a malfunctioning water pump or a loose hose clamp can lead to coolant escaping from the system. Other potential sources of leaks include the thermostat housing, intake manifold gasket, heater core, and even the radiator cap. In more severe cases, a blown head gasket may be the issue, which requires immediate attention to prevent engine damage. By being aware of these common failure modes, you can more effectively diagnose the source of the leak and take appropriate action, whether that involves a simple repair or seeking professional assistance.
Addressing a coolant leak in your Dodge Omni is not just a matter of convenience; it is a critical step in ensuring the longevity and safety of your vehicle. Coolant leaks can lead to severe overheating, which may cause catastrophic engine failure if left unchecked. The cooling system is essential for maintaining optimal engine temperatures, and a leak can quickly deplete coolant levels, resulting in inefficient cooling and increased risk of engine damage. Common sources of these leaks, such as damaged hoses or a faulty radiator cap, can worsen over time, leading to more extensive repairs and higher costs. Ignoring the symptoms of a coolant leak can also lead to inconvenient breakdowns, leaving you stranded and facing unexpected repair bills. Therefore, it is imperative to monitor your coolant levels regularly and address any leaks immediately to prevent serious safety risks and ensure your Dodge Omni operates smoothly.
