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 2016 Acura RDX, begin by checking the coolant level when the engine is cool, as this will provide an accurate reading. Look for signs of a leak, such as overheating, a drop in coolant levels, or unusual exhaust smoke. Pay close attention to the reservoir, radiator, and hoses, particularly at connection points, as these are common areas for leaks. Additionally, inspect the thermostat housing, which is another frequent source of coolant issues. If you cannot identify the leak after these checks, it may be time to consult a qualified mechanic for a thorough diagnosis and repair. By following this systematic approach, you can pinpoint the source of the coolant leak and take the necessary steps to resolve it.
When tackling a coolant leak in a 2016 Acura RDX, it's essential to understand the common problems that can lead to this issue. One prevalent cause is corrosion and grime buildup in the radiator, which occurs due to the constant exposure to heat and pressure over time. Regular maintenance is crucial; neglecting it can result in wear and tear on the radiator, making it more susceptible to leaks. Additionally, pressure issues within the cooling system can exacerbate the problem, leading to potential failures. Physical damage from collisions or road debris can also compromise the integrity of the radiator. Furthermore, loose hose connections or a broken radiator can create pathways for coolant to escape. Don't overlook the water pump, as it plays a vital role in circulating coolant, and any malfunction can contribute to leaks. Lastly, issues with the heater core may not only lead to coolant loss but can also result in a distinct smell of engine coolant inside the vehicle. By being aware of these common causes, DIYers can better diagnose and address coolant leaks effectively.
Addressing a coolant leak in your 2016 Acura RDX is not just a matter of routine maintenance; it is an urgent issue that requires immediate attention. Ignoring the signs of a coolant leak, such as overheating or colorful puddles under your vehicle, can lead to severe engine damage and costly repairs. The coolant system plays a vital role in regulating engine temperature, and a leak can compromise this function, resulting in overheating and potential engine failure. Additionally, if the leak originates from critical components like the radiator or hoses, the risk of further damage increases significantly. Regularly monitoring your coolant levels and being proactive about repairs can save you from dangerous driving conditions and expensive fixes down the line. Therefore, if you notice any symptoms of a coolant leak, it is crucial to have your vehicle inspected and serviced without delay to ensure your safety and the longevity of your Acura RDX.
