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 2012 Suzuki Equator, start with a thorough initial observation. Look for any colored puddles beneath your vehicle, as the color of the coolant can vary based on the type used. Pay attention to your dashboard's temperature gauge and any warning lights, as these can provide crucial clues about potential leaks. Once you've gathered this preliminary information, prepare for a visual inspection by ensuring the engine is cold and wearing safety glasses. After driving the vehicle to warm it up, park it on a flat surface and allow it to cool for a couple of hours. This will help you identify any coolant pools and narrow down their source. If you suspect a leak, utilize a cooling system pressure testing kit to pressurize the system and check for drops in pressure or visible leaks. For smaller leaks that are hard to detect, consider adding a UV dye to the coolant and using a UV light to spot any leaks after running the engine. Additionally, inspect the coolant tank, heater hoses, and heater core for any signs of leaks. If you suspect a more serious issue, such as a head gasket leak, specialized tools can help detect combustion gases in the coolant. By following this structured diagnostic approach, you can effectively identify the source of the coolant leak and determine the best course of action for repair.
When dealing with coolant leaks in a 2012 Suzuki Equator, it's essential to understand the various common problems that can arise within the cooling system. External leaks often stem from worn radiator hoses or connections, which can develop small tears over time, leading to coolant loss. Additionally, corrosion within the radiator itself can create leaks, significantly impairing its function and potentially causing complete failure. The coolant reservoir is another area to inspect, as cracks or damage can result in leaks. A faulty radiator cap may also contribute to the issue by failing to maintain proper pressure, allowing coolant to escape through the overflow. On the internal side, a blown head gasket is a serious concern, as it can lead to coolant mixing with engine oil, resulting in severe engine damage if not addressed quickly. Water pump failure is another potential culprit, often indicated by water marks or corrosion beneath the pump. Lastly, thermostat malfunctions can cause coolant to leak or boil off, exacerbating the problem. By monitoring for signs such as coolant pooling, a sweet odor, or steam from under the hood, DIYers can identify and address these issues early, preventing further damage to the engine.
Addressing a coolant leak in your 2012 Suzuki Equator is not just a matter of routine maintenance; it is an urgent necessity that can prevent catastrophic engine damage and ensure your safety on the road. A coolant leak, if left unattended, can lead to overheating, which may warp head gaskets or crack the engine block, resulting in costly repairs that could have been avoided. Even minor leaks can escalate quickly, transforming from a small drip into a significant issue that drains coolant rapidly, putting your engine at risk of failure. Furthermore, neglecting a coolant leak can lead to corrosion within the cooling system, diminishing the efficiency of your radiator and compromising your vehicle's heating and cooling capabilities. The urgency of addressing this issue cannot be overstated; if you notice any signs of a leak, it is advisable to inspect the source immediately, whether it be a damaged hose or a more serious problem like a blown head gasket. For your safety and the longevity of your vehicle, prompt action is essential—consider towing your vehicle to a mechanic if the leak is substantial, as driving with low coolant levels can lead to severe engine overheating and failure.
