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.
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 and fix a coolant leak in your 1995 Toyota Tercel, begin by visually inspecting the engine bay and the area beneath the vehicle for any signs of coolant, such as puddles or stains. This initial step can often reveal the source of the leak without further testing. If no obvious leaks are found, proceed with a pressure test of the cooling system, which can help pinpoint hidden leaks. Next, carefully examine all hoses and connections for any signs of wear, such as cracks or bulges, and replace any damaged components. Pay special attention to the radiator, as leaks here can often be repaired, but extensive damage may necessitate a full replacement. Additionally, check the water pump and heater core for leaks, as these components are common culprits in coolant loss. Finally, inspect the head gasket for any signs of damage, as a faulty gasket can lead to serious engine issues. Once all potential leaks have been addressed, refill the cooling system with the appropriate coolant mixture, start the engine, and monitor for any further leaks or overheating, ensuring your vehicle runs smoothly and efficiently.
When dealing with coolant leaks in a 1995 Toyota Tercel, it's essential to understand the common problems that may arise. One of the primary culprits is worn-out hoses, which can crack and leak over time due to exposure to heat and pressure. Additionally, a faulty radiator can develop corrosion or damage, leading to significant coolant loss. The water pump, responsible for circulating coolant, can also be a source of leaks if it becomes worn or damaged. Another often-overlooked issue is a cracked radiator cap, which can allow coolant to escape from the system. Furthermore, loose or damaged hose clamps may fail to create a proper seal, resulting in leaks at the connection points. Lastly, a leak directly in the radiator can cause coolant to seep out, necessitating immediate attention. By regularly inspecting these components and addressing any signs of wear or damage, DIY enthusiasts can effectively manage coolant leaks and maintain the health of their Toyota Tercel.
Addressing a coolant leak in a 1995 Toyota Tercel is of utmost urgency due to the serious risks associated with engine overheating and potential damage. Coolant plays a critical role in maintaining optimal engine temperature; a leak can lead to a rapid loss of coolant, resulting in the engine running hotter than normal. This overheating can cause severe damage, including warped cylinder heads or a blown head gasket, which can lead to costly repairs. Furthermore, neglecting a coolant leak not only compromises the vehicle's performance but also poses safety risks, as an overheated engine can fail unexpectedly while driving. By addressing the leak promptly, you can prevent these dangerous situations and save yourself from extensive repair bills down the line. Therefore, if you notice any signs of a coolant leak, such as puddles under the vehicle or a drop in coolant levels, it is crucial to take immediate action to ensure the longevity and safety of your Tercel.
