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.
When the radiator fans stop functioning properly, the engine temperature will rise. The spike in temperature will be highest when the vehicle is idling at a stop, but should subside once the vehicle begins moving again.
Additionally, the air conditioner typically won't blow as cold. This is because the air from the radiator fans also blows across the air conditioning condenser, so when the fans fail, both systems suffer.
You'll also usually see the check engine light and notice a drop in fuel economy. It's possible the fan will start making noise if it's failing, as well.
When troubleshooting radiator fan issues in your INFINITI M35, it's essential to adopt a diagnostic approach that prioritizes simplicity and efficiency. Begin by inspecting the fuses and relays associated with the radiator fan, as these are often the most straightforward culprits for electrical failures. If the fuses are intact, proceed to examine the electrical connections at the fan itself, ensuring that there are no loose wires or corroded terminals that could disrupt power flow. Next, assess the signal systems that activate the fan, such as the air conditioning and engine cooling systems, to confirm they are functioning correctly. If the fan motor appears to be the issue, consider testing it directly to determine if it operates as intended. By following this methodical process, you can effectively identify and resolve radiator fan problems, ensuring your vehicle remains cool and operates smoothly.
When troubleshooting radiator fan issues in an INFINITI M35, it's essential to understand the common problems that can arise within the cooling system. Overheating is often linked to several factors, including coolant leaks from the water pump, radiator, or hoses, which can significantly impact engine performance. Additionally, the radiator fan itself may malfunction due to a faulty Radiator Fan Control Module or Engine Cooling Fan Module, leading to either constant operation or complete failure. A thorough inspection of the electrical system is crucial, as issues with fuses, relays, and connections can disrupt the fan's functionality. It's also important to check for any bad grounds or loose connectors that may hinder performance. If coolant leaks are present, they should be addressed promptly to prevent further overheating. Lastly, after any maintenance involving the cooling system, ensure proper coolant bleeding to avoid air pockets that can cause heating issues. By systematically addressing these common problems, you can effectively diagnose and resolve radiator fan issues in your INFINITI M35, ensuring optimal engine temperature regulation.
Fixing a non-working radiator fan in your INFINITI M35 is not just a matter of convenience; it is an urgent necessity that can prevent severe consequences. When the radiator fan fails, the risk of engine overheating escalates dramatically, which can lead to catastrophic engine damage and costly repairs. The fan is essential for maintaining the engine's optimal temperature, and without it, the engine may overheat, causing components to warp or seize. This situation not only jeopardizes the vehicle's performance but also poses a safety risk to you and others on the road. Additionally, neglecting this issue can lead to more extensive electrical problems, such as short circuits or excessive electrical draw, which can further complicate repairs and increase costs. By addressing the malfunction promptly, you safeguard your vehicle's longevity and performance, ensuring that it operates efficiently and safely. Therefore, it is crucial to prioritize fixing the radiator fan to avoid these serious repercussions.
