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.
When troubleshooting coolant leaks in your Honda Element, start by observing the symptoms your vehicle is exhibiting. Look for signs such as engine overheating, a noticeable drop in coolant levels, or colorful puddles forming under the car. These indicators can help you pinpoint the source of the leak. Begin your diagnostic process by inspecting the coolant hoses and connections for any visible cracks or pinhole leaks, as these are common culprits. Next, check the radiator and its components, including the thermostat, to ensure they are functioning correctly. If the thermostat is stuck closed, it can prevent coolant circulation, leading to overheating. Additionally, listen for unusual sounds, such as a squealing belt, which may suggest that the cooling system is under strain. If you suspect a more complex issue, such as a clogged radiator or a malfunctioning cooling fan, consider consulting a repair manual or online resources for further guidance. By systematically addressing these areas, you can effectively identify and resolve coolant leaks, ensuring your Honda Element runs smoothly and efficiently.
When dealing with coolant leaks in a Honda Element, it's essential to understand the common problems that can arise within the cooling system. One frequent issue is the deterioration of rubber hoses, which can become brittle over time, leading to cracks and leaks. Additionally, the radiator itself may develop leaks due to corrosion or physical damage, often resulting in visible puddles of coolant beneath the vehicle. Another common culprit is the water pump, which can fail and cause coolant to leak from its seals. Drivers should also be aware of the potential for pinhole leaks in the coolant tube that connects the thermostat to the engine, as these can be less obvious but equally problematic. By recognizing these common failure modes, you can take proactive steps to diagnose and address coolant leaks effectively, ensuring your Honda Element remains in optimal working condition.
When dealing with a coolant leak in your Honda Element, it's crucial to act swiftly to prevent further damage to your vehicle and ensure your safety on the road. Ignoring symptoms such as engine overheating, a noticeable drop in coolant levels, or the presence of colorful puddles beneath your car can lead to severe engine damage, costly repairs, and even dangerous driving conditions. Start by identifying the leak; common signs include white smoke from the engine and a squealing belt, which can indicate overheating. Once you've pinpointed the issue, locate the coolant reservoir and inspect the hoses and connections for any visible leaks. Pay special attention to the radiator, as it is a frequent culprit for coolant loss. If you don't see any obvious leaks, check the coolant tube that runs from the thermostat to the cylinder head, as it can develop pinhole leaks that are harder to detect. By addressing these issues promptly, you not only safeguard your vehicle's performance but also enhance your safety, making it essential to tackle any signs of a coolant leak without delay.
