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 troubleshooting radiator fan issues in your INFINITI I35, start with the basics to efficiently identify the problem. Begin by inspecting the fuses and relays associated with the radiator fan, as these are often the simplest components to check and replace if faulty. Next, examine the radiator for any signs of leaks, particularly around the cap, since coolant loss can lead to overheating and may mimic fan failure. If these initial checks do not resolve the issue, proceed to test the radiator fan motor by applying direct power to it; this will help determine if the motor itself is operational. Additionally, consider the condition of the thermostat and heater blower motor, as these can also influence the fan's performance. If you encounter persistent problems, consulting with auto experts or fellow enthusiasts can provide valuable insights and solutions. By following this diagnostic approach, you can effectively address radiator fan issues and maintain optimal engine temperature in your INFINITI I35.
When tackling the issue of a non-working radiator fan in your INFINITI I35, it's essential to understand the common problems that could be at play. One of the first things to check is the fuse; a blown fuse is often the culprit behind fan failure. If you find that the fuse is burnt, replacing it with one of the same size and type is a straightforward fix, but if it blows again, this could indicate a more serious electrical issue, such as a short circuit. Additionally, inspecting the fan itself for any visible damage is crucial, as physical wear and tear can prevent it from operating effectively. Relay issues are another common problem; if the relays are faulty, replacing them can restore functionality. Low coolant levels can also lead to overheating, which may cause the fan to stop working, so ensure that your coolant is at the appropriate level. Lastly, don’t overlook the fan motor and wiring; any problems here can disrupt the fan's operation. By being aware of these common failure modes, you can systematically diagnose and address the issues, ensuring your radiator fan operates efficiently and your vehicle remains cool.
When the radiator fan in your INFINITI I35 is not functioning, it is crucial to address the issue without delay. A malfunctioning radiator fan can lead to severe overheating, which poses a significant risk to your engine's health and overall vehicle performance. Ignoring the symptoms can result in costly repairs and potential engine failure. Common culprits include a faulty fan assembly, a defective fan clutch, or issues with the coolant temperature sensor. Additionally, electrical problems such as blown fuses, bad relays, or damaged wiring can also prevent the fan from operating effectively. To ensure your vehicle remains safe and reliable, it is essential to conduct a thorough inspection of these components. Regular maintenance and prompt repairs not only enhance the longevity of your vehicle but also safeguard against the dangers of overheating, making it imperative to act swiftly when you notice any signs of fan failure.
