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 effectively diagnose the non-working radiator fan in your 1996 Pontiac Bonneville, start by checking the fuse associated with the fan. A blown fuse is a common and easily fixable issue that can prevent the fan from operating. If the fuse is intact, proceed to test the fan motor using a multimeter to check for continuity, which will help you determine if the motor itself is functional. Next, inspect the fan relay to ensure it is properly sending power to the fan motor when the engine reaches a high temperature. If these components are working correctly, examine the temperature sensor to confirm it is accurately signaling the fan to activate at the appropriate temperature. Additionally, look for any wiring issues that may be causing a disconnection or damage in the electrical system. Finally, check the fan blades for any obstructions or damage that could hinder their movement. By following this methodical approach, you can effectively identify the root cause of the radiator fan's malfunction and take the necessary steps to fix it.
When diagnosing why the radiator fan in a 1996 Pontiac Bonneville has stopped working, it's essential to consider several common problems that could be at play. A faulty fan motor is often the primary suspect, as these motors can wear out over time, leading to complete failure. Additionally, a blown fuse may disrupt the electrical supply to the fan, rendering it inoperative. Another potential issue is a malfunctioning relay, which is responsible for delivering power to the fan motor; if this component fails, the fan will not receive the necessary power to operate. The coolant temperature sensor also plays a critical role in regulating the fan's operation; if it is faulty, it may fail to trigger the fan when needed. Furthermore, wiring issues, such as damaged or corroded connections, can impede the flow of electricity to the fan, causing it to malfunction. Lastly, physical obstructions in the fan blades, such as debris or foreign objects, can prevent the fan from spinning properly. By systematically checking these components, DIYers can effectively troubleshoot and resolve the issue of a non-functioning radiator fan in their Pontiac Bonneville.
Repairing a non-functioning radiator fan in a 1996 Pontiac Bonneville is an urgent matter that should not be overlooked. The radiator fan is essential for maintaining optimal engine temperature by facilitating heat dissipation from the radiator. When this fan fails, the engine is at risk of overheating, which can lead to severe and costly damage. Overheating can warp cylinder heads, blow head gaskets, and damage the water pump, all of which can escalate repair costs significantly. Moreover, if the overheating persists, it could result in catastrophic engine failure, necessitating a complete engine replacement. Therefore, addressing the malfunctioning radiator fan promptly is crucial not only for the immediate health of your vehicle but also for preventing long-term damage and ensuring the longevity of your Pontiac Bonneville. Taking action now can save you from extensive repairs and keep your vehicle running smoothly.
