I just purchased this truck and noticed it making a roaring noise, but just occasionally. I took it to the dealership and they replaced the cooling fan clutch. Two days later it started making the noise again. Seems like if you drive for thirty minutes or more, turn the engine off for a brief time and then restart if, that is when the noise starts and continues until you shut it off. I called the service dept. Back and they told me that the clutch had been replaced in August and in September of 2019. What could be causing it to go bad continuously? I am very concerned. I haven't even made my first payment on the truck and it wasn't cheap. Can you shed any light on this for me?

The fan clutch on this vehicle is controlled by a module. This is a technical definition of how it works.

The cooling fan clutch is utilized to control cooling fan operation. This fan clutch is controlled by the ECM. The ECM monitors coolant temperature and intake manifold temperature to determine when to engage the cooling fan. There are also additional sensors monitored by the ECM for fan control (for example, air conditioner pressure and transmission temperature). The fan clutch is an electro-viscous fan clutch.

Since the fan is affected by several different items, the dealership needs to check the items listed above. The vehicle is under full manufacturer warranty. Thus, if you get no satisfaction from the dealer, contact the Nissan Zone Rep nearest to you. The phone numbers for customer service should be located in the owner's manual.

I attached a pic below of the item so you can see how it looks. If the dealer has replaced it three times in (at 10,000 miles), it's not the fan but one of the sensors, the ECM, or a wiring issue.

Let me know if I can help.

I talked with the service manager at the dealership today. He tried to talk me into taking the truck to a different Nissan dealership and told me that I would have to deal with the noise. Like that was normal. If normal, then why did Nissan pay to have it replaced three times? He said that he would arrange a meeting with someone at Nissan, but I have not heard anything back. I called Nissan America and started a case number concerning this. I tried to get the name of my Nissan Zone Rep. To no avail. Nissan said they would contact me by end of day tomorrow. I'll let you know how it progresses.

Just wanted you to know that I think the truck is fixed and what happened. I got with Nissan Headquarters and they followed what was going on and acted as a liaison for us. I think that the person that assisted the mechanic at the dealership was the zone representative. The mechanic was able to get the truck to make the sound that we were hearing. The zone rep told him to check the F32 connector for the fan clutch. When examining the connector the mechanic realized that it had at some point been damaged, possibly chewed by rodents, and that it had been repaired by wrapping the wires with electrical tape and not soldering the end connector. (I think that is what he said). The zone rep told him to replace the wiring harness. The dealership did this and I believe that it is corrected. Drove the truck for quite some time after picking it up yesterday and it never had any issues.

The dealership also gave us a loaner car at no expense while the truck was in the shop. I really appreciate your assistance in dealing with this. You got us on the right track and I thank you very much.

That is great news. It sounds like prior to you owning the vehicle, there was a problem with a broken wire, and rather than fixing it properly, someone taped things together. It's hard for me to understand why someone would do that on such a new vehicle, but people do it.

I'm really happy to know it's fixed. Please feel free to come back anytime in the future if you have questions or need help.

Take good care of yourself,

Joe
