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.

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 2013 Mercedes-Benz SLK55 AMG, start with a thorough visual inspection of the vehicle. Look for any visible signs of coolant pooling under the car or around critical components such as the radiator, hoses, and water pump. If you notice any wet spots or discoloration, this could indicate a leak. Next, consider performing a pressure test on the cooling system, which can help pinpoint the exact location of the leak by pressurizing the system and revealing weak spots. Regularly checking your coolant levels is also essential; a consistent drop in levels may suggest a leak that needs attention. Pay close attention to the condition of the radiator and hoses, inspecting them for cracks or bulges that could lead to coolant loss. Additionally, be aware of any unusual signs such as white smoke from the exhaust or a sweet smell, both of which can indicate coolant entering the combustion chamber. If these steps do not lead to a clear diagnosis, or if you feel uncertain about the process, it may be wise to consult a qualified mechanic or a Mercedes-Benz service center for professional assistance. By following this structured approach, you can effectively identify and address coolant leaks in your vehicle.
When dealing with coolant leaks in a 2013 Mercedes-Benz SLK55 AMG, it's essential to understand the various components that could be at fault. A faulty radiator is often a primary suspect, as it can develop leaks due to corrosion or physical damage. Additionally, the water pump plays a crucial role in circulating coolant; if it malfunctions, it can lead to significant leaks. Over time, the hoses that transport coolant can wear out, becoming brittle and prone to cracking, which can also result in leaks. Another serious issue could be a cracked engine block, which not only causes coolant loss but can lead to severe engine damage if not addressed. Furthermore, loose or damaged hose clamps may fail to secure the hoses properly, allowing coolant to escape. Lastly, a leaking heater core can contribute to coolant loss, often accompanied by a sweet smell inside the cabin. Regular inspections and maintenance are vital to catch these problems early, ensuring your SLK55 AMG remains in optimal condition and preventing costly repairs down the line.
When it comes to repairing a coolant leak in a 2013 Mercedes-Benz SLK55 AMG, urgency cannot be overstated. Coolant plays a vital role in maintaining optimal engine temperature; without it, the risk of overheating increases significantly. An overheating engine can lead to catastrophic damage, including warped cylinder heads or even complete engine failure, which can be both costly and time-consuming to repair. Additionally, a persistent coolant leak can adversely affect the vehicle's performance, leading to decreased fuel efficiency and a rougher ride. By addressing the leak promptly, you not only safeguard your engine from severe damage but also enhance the overall driving experience. Ignoring the symptoms of a coolant leak can result in more extensive repairs down the line, making it crucial for DIY enthusiasts to act swiftly. Taking the time to fix this issue now can save you from facing much larger problems in the future, ensuring your SLK55 AMG remains in peak condition.
