Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
Does the noise seem to be coming from the engine area ? Under the truck? it only does it on first start up?
How many miles on the truck?
Thank you, ***** ***** many miles do you have on the truck?
This sounds like it could be a timing chain tensioner bleeding down. So when you first start the truck, it has to build up pressure which it doesn't take long to do, but in the mean time the chain slaps around which could be giving off that grinding or scrapping type noise.
if indeed my thoughts are correct, this is covered under the Powertrain warranty which is 5 years or 60k miles. So what I would suggest you do is drop it off at night or after work, for them to check it the following morning to try to duplicate the noise. This way they can replace the tensioner for you.
Do you have any more questions on this?
Yes it would be. This is a Factory warranty. So it does not go by owners. It just goes by time and mileage. You also have a 3 year or 36k bumper to bumper warranty. That could be expired by time.
How long ago did you buy it?
You are fine to take it to the dealer. If it was recent, like the past couple months, I would have told you to take it back to where you brought it.
But to much time has past for that. So you would need to have the dealer look at this and if it's the tensioner like I am thinking, it would be covered under warranty
It should not make any noise when first starting up.
As for worst case, I can not give you a ball park. I am unable to hear the noise to verify my thoughts. I am basing this on my experience and what I have seen.
As for your belt, If it's a after market belt I have seen them make noises cause they are softer than the OEM belts. So if this noise started shortly after changing the drive belt, I would get a belt from the dealer and install that first to see if the noise goes away that way.
The softer belt may make the auto belt tensioner slap around more.
