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.
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 and fix a coolant leak in your 1992 Chevrolet Blazer, start by visually inspecting the area beneath your vehicle for any signs of coolant, such as puddles or stains. This initial check can often reveal the leak's location. Next, conduct a pressure test on the cooling system, which can help identify leaks that are not immediately visible. Pay close attention to the radiator cap, as a damaged cap can lead to leaks; replace it if necessary. Inspect all hoses and connections for cracks or loose fittings, and replace any damaged components. The water pump is another critical area to examine, as leaks often originate from here. Additionally, check the heater core and radiator for any signs of corrosion or damage. Once you have pinpointed the source of the leak, proceed with the appropriate repairs or replacements, whether that involves fixing a hose or replacing a gasket. After addressing the issue, refill the cooling system with the correct coolant mixture and start the vehicle to ensure that the leak has been resolved. By following this structured approach, you can successfully diagnose and repair coolant leaks, ensuring your Blazer runs smoothly.
When dealing with coolant leaks in a 1992 Chevrolet Blazer, it's essential to understand the common problems that may arise. One of the primary culprits is a damaged radiator, which can develop leaks due to corrosion or physical damage. Additionally, worn-out hoses are frequent offenders; over time, the rubber can deteriorate, leading to cracks and leaks. The water pump is another critical component that can fail, causing coolant to leak from the pump itself or its gasket. In more severe cases, a cracked engine block may result in significant coolant loss. It's also important to check the hose clamps, as loose or damaged clamps can prevent a proper seal, allowing coolant to escape. Other potential sources of leaks include a faulty heater core, issues with the radiator cap, and head gasket failure, which can lead to coolant leaking into the engine cylinders or externally. Regular inspections and maintenance are vital to catch these problems early, ensuring your Blazer runs smoothly and preventing costly repairs down the line.
Addressing a coolant leak in your 1992 Chevrolet Blazer is of utmost importance due to the significant risks associated with neglecting this issue. Coolant is essential for maintaining the engine's temperature, and a leak can lead to a rapid loss of coolant, resulting in overheating. This overheating can cause severe damage to vital engine components, including the cylinder head gasket and pistons, which may lead to costly repairs or even complete engine failure. Furthermore, ignoring a coolant leak can exacerbate the situation, potentially damaging other critical parts such as the water pump, radiator, or heater core, thereby increasing repair costs and complicating the issue. Regularly checking your coolant levels and promptly addressing any leaks not only helps maintain the efficiency of your cooling system but also safeguards your engine's longevity. Therefore, it is crucial to act swiftly when you notice signs of a coolant leak to prevent serious and expensive damage to your vehicle.
