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 2016 Nissan Versa Note, start with a thorough visual inspection of the vehicle. Begin by checking for any visible leaks beneath the car, as puddles or stains can indicate where the coolant is escaping. Next, focus on the radiator, looking for wet spots or white residue that may suggest damage or leaks. Don’t overlook the hoses connected to the radiator; inspect them for any signs of cracks or bulges that could lead to coolant loss. The water pump is another critical component to examine, as leaks or damage here can also contribute to coolant issues. If the problem remains elusive, consider performing a pressure test on the cooling system, which can help identify leaks that are not immediately visible. Additionally, inspect the heater core, as leaks here may manifest as a sweet smell inside the vehicle or fogging on the windows. Finally, monitor the coolant levels in the reservoir over several days to determine if there is a consistent loss, which can further confirm the presence of a leak. By following this systematic approach, you can effectively diagnose and address any coolant leak issues in your Nissan Versa Note.
When dealing with coolant leaks in a 2016 Nissan Versa Note, it's essential to understand the common problems that may arise. A damaged radiator is often a primary culprit, as corrosion or physical damage can lead to significant leaks. Additionally, a faulty radiator cap can disrupt the pressure balance within the cooling system, resulting in leaks. Over time, the hoses that transport coolant can wear out, developing cracks that allow coolant to escape. Another potential issue is a leaking water pump, which can create puddles in the engine bay. In more severe cases, a cracked engine block may be the source of the leak, although this is less common. Lastly, loose or damaged hose clamps can lead to leaks at connection points, making it crucial to inspect these areas regularly. Addressing these issues promptly is vital to prevent overheating and protect your engine, so if you notice any signs of a coolant leak, consider checking these components before seeking professional help.
Addressing a coolant leak in your 2016 Nissan Versa Note is not just a matter of convenience; it is crucial for the safety and longevity of your vehicle. Coolant plays a vital role in regulating engine temperature, and a leak can quickly lead to overheating, which may result in severe engine damage. Ignoring this issue can escalate into costly repairs, as an overheated engine can suffer from warped components or even complete failure. Additionally, a coolant leak may indicate underlying problems within the cooling system, such as a compromised radiator or a failing water pump. By tackling the leak early, you not only preserve the integrity of your engine but also enhance your vehicle's overall performance and reliability. Therefore, if you notice any signs of a coolant leak, it is imperative to act swiftly to prevent further complications and ensure your Nissan Versa Note remains safe and operational.
