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.
Over time serpentine belts stretch, crack, and the ribs that ride on the accessory pulleys being to wear smooth. A squealing noise that increases with engine speed or as engine driven accessories are turned on may be noted. The noise is caused by the belt slipping on the pulleys, insufficiently driving them. Ineffective air conditioning, a battery warning light, or intermittent power steering assist can result from this.
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.

When the engine coolant temperature sensor fails, it will send inaccurate information to the vehicle’s computer, causing the computer to react to false operating conditions. This will cause the engine to consume more fuel than normal, depleting fuel mileage, and causing black, sooty smoke from the engine under moderate to heavy acceleration. The check engine light will illuminate, and on-board diagnostic trouble codes may be stored for exhaust and emission system failure, fuel delivery system failure, and engine cooling system failure. Overheating may also occur, as the coolant sensor may be leaking fluid out of the engine, creating a an air pocket in the system.
To diagnose the non-functioning radiator fan in your 1995 Buick Skylark, begin with a systematic approach that prioritizes simple checks before delving into more complex diagnostics. Start by inspecting the fuse associated with the radiator fan; a blown fuse is a common and easily fixable issue. If the fuse is intact, proceed to manually spin the fan blade to check for any obstructions that could hinder its movement. This step is crucial, as physical blockages can prevent the fan from operating even if the electrical components are functioning correctly. If both the fuse and the fan blade are in good condition, you may need to investigate further into the electrical connections or the fan motor itself, but starting with these basic checks can often lead to a quick resolution.
When troubleshooting a non-functioning radiator fan in a 1995 Buick Skylark, it's essential to consider several common problems that could be at fault. One of the primary culprits is the fan assembly itself, which may be damaged or worn out, preventing the fan from operating. Additionally, the fan clutch can fail, leading to inadequate cooling performance. Another critical component to inspect is the coolant temperature sensor; if it malfunctions, it may not signal the fan to turn on when needed. Electrical issues are also prevalent, with blown fuses or a faulty starter relay often causing the fan to remain inactive. If the fan motor has burned out, it will need replacement, as a functioning motor is crucial for the fan's operation. Furthermore, the vehicle's Engine Control Module (ECM) could be malfunctioning, affecting the fan's performance. Lastly, check for any wiring damage that could disrupt the electrical flow to the fan. By systematically examining these areas, DIYers can effectively diagnose and resolve the issue, ensuring the radiator fan operates as intended.
Repairing the non-functioning radiator fan in a 1995 Buick Skylark is an urgent matter that should not be overlooked. The radiator fan is essential for maintaining optimal engine temperature by effectively dissipating heat from the radiator. When this component fails, the risk of engine overheating significantly increases, which can lead to severe damage such as warped cylinder heads or complete engine failure. Additionally, an overheating engine can result in decreased fuel efficiency and higher emissions, compounding the problem and leading to more extensive repairs. Other vital components, including the water pump, thermostat, and head gasket, may also suffer from the strain of excessive heat, resulting in costly repairs that could have been avoided. Therefore, addressing radiator fan issues promptly is crucial not only for the immediate health of your vehicle but also for preventing future complications and ensuring its longevity. Regular maintenance and timely repairs are key to keeping your Buick Skylark running smoothly and efficiently.
