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 2010 Chrysler PT Cruiser, start by inspecting the hose connections throughout the cooling system. Look for any signs of looseness or visible leaks, as these are often the easiest issues to fix. Next, examine the radiator for any damage or corrosion, which can indicate a more serious leak. If the radiator appears intact, proceed to check the water pump, as a malfunction here can also lead to coolant loss. Utilizing a pressure tester can help identify leaks in various parts of the cooling system, although it may not always detect head gasket issues. Finally, keep an eye out for slow leaks, particularly around the head gasket area, as these can develop gradually and may require more in-depth investigation. By following this structured approach, you can efficiently pinpoint the source of the coolant leak and take the necessary steps to address it.
When addressing a coolant leak in a 2010 Chrysler PT Cruiser, it's crucial to understand the common problems that may be contributing to the issue. One frequent culprit is loose hose connections, which can allow coolant to escape and lead to overheating if not tightened properly. Additionally, a broken radiator can be a significant source of leaks, as cracks or damage can compromise the system's integrity. Another potential issue is a failed water pump, which not only circulates coolant but also plays a vital role in maintaining the engine's temperature. By inspecting these components, DIYers can effectively diagnose and address the source of the coolant leak, ensuring the vehicle operates smoothly and preventing further damage.
Addressing a coolant leak in your 2010 Chrysler PT Cruiser is not just a matter of convenience; it is a critical safety concern that demands immediate attention. Ignoring a coolant leak can lead to severe engine overheating, which may result in catastrophic damage that could require costly repairs or even a complete engine replacement. Additionally, low coolant levels can compromise your vehicle's heating system, leaving you uncomfortable during colder months. More importantly, a coolant leak often signals deeper mechanical issues, such as loose hose connections, a damaged radiator, or a failing water pump, all of which can escalate into more significant problems if left unchecked. By addressing the leak promptly, you not only safeguard your vehicle's performance but also prevent the risk of more extensive and expensive repairs down the line. Therefore, if you notice any signs of a coolant leak, it is crucial to take action immediately to ensure the longevity and reliability of your Chrysler PT Cruiser.
