I don't know what the technical name for this part is. It is a metal air scoop under the engine that directs air over some cooling fins. It hangs down far enough to get caught on parking lot deviders. We've banged ours twice and severly bent it all out of shape. I removed it and beat it back into shape as best I could but it is really thick steel and is difficult to bend back. I need to stop by the dealer this week and order up a new one I guess. Anyone had this problem yet?

Thats it!

Thats the picture! Thanks, my discriptive powers are pretty limited. I'm not sure what it directs air to - it may be the transmission cooler? I agree that it appears to be an afterthought - probably just a quick fix to a cooling problem? I wonder if the '04's are the same?

It directs air to the CVT transmission's cooling fins

That scoop directs air to the CVT transmission's cooling fins. I just wonder why Nissan chose to do this versus installing a heavy duty transmission cooler on the car? Maybe the CVT fluid (with its rubber particles and what not) doesn't flow well through a radiator-type cooling device?

Nissan should have either put sometype of protection like a mini-brush guard there, or made the scoop out of rubber so that it would bend back to shape.

See how the back edge rolls up? I think that will create a pressure bubble at the bottom of the cavity and help push the air at the top over the fins. But I'm not an aerodynamicist.

good point....

i didnt see that............

at best though, it will make for turbulance there..... not as much controlled or 'directed' airflow.........

((im no specialist at all myself, either).... just an observationist...lol

Phew!
Man that is Ugly.

Built a dirt car from scratch once that had better workmanship.

Almost all Kit cars look better......even underneith.

I'll bet that that was a last minute add on.
Why? Disturbing numbers at the end of long range testing?
Really ugly.

I can see where the guys are banging on that thing in Parking lots.....
Thanks clydesdale for bringing the subject up.

Please don't show anymore pix like that.:D

And yes, 'force, I DO appreciate your pix, even when they show stuff I'ld rather not know about.:1:

Ok Enforcer, I just wanna know about your garage (note the lift and shop in the background, seemingly just to shoot this pic!!?!?) You have now blown your cover as a Secret Nissan Engineering Operative.:D

LOL!

I knew about this before I bought it. I took a bunch of underside pictures of the Z and MO at the dealer when I bought them. Have posted the MO pics in the gallery. Pics of Z underside are on my website. The dealer mechanics thought I was nuts. Told them I wanted to take pics of the underside for my website. They just shook their heads and said OK :toothless. That is one of the reasons you don't want to take the MO off road.

While parking at a restaurant yesterday, I was surprised to hear mine hit the concrete car stop. The car stop didn't seem to be exceptionally tall, but it made an awful scraping sound. It caused me to be more aware of how low this transmission guard is and I'll have to be more careful when parking.

Perhaps the "scoop" underneath the car is not to direct air to the cooling fins but rather to protect the bottom of the transmission pan from damage. Would you rather have high curbs scrape your transmission pan? Personally I do not mind the ugly scoop since it seems to be doing its job.

As for an aftermarket transmission cooler, I wish someone else here installed one already. I had one in my Maxima and it performed great. I would install one in the Murano if I knew that the CVT wasn't affected.

I whacked mine once and now it's slightly angled down. Should make it even more effective at cooling the CVT! I've thought about taking it off and straightening it out, but, I'd probably just whack it again at some point.

Just watch those curbs!

Jaak ... My scoop is bent down and pushed back so much that it effectively closes off the back. Looking at the photo that Enforcer posted you see that there is about an inch gap at the rear of the scoop. Now mine is closed off and I suspect this greatly reduces its effectiveness. I'm going to stop by the dealer soon and ask them if they know its actual purpose - air scoop or fin protector - and probably order up a new one. I don't suppose this would be a warrenty item?

You could unbolt it and hammer it back into shape, then stick it back on. Considering it will probably get nailed again at some point, why buy a new one to smash up?

Mine's just bent down about half an inch at the front, so nothing major. I could probably take it off and throw it in with the spare tire for all the difference it would make, except in the really hot weather... My understanding is that it helps keep the CVT cool when it's really stinkin' hot out.

What do you think about just removing it. Shouldn't you get a warning light if the CVT starts heating up. This summer I was stuck in traffic for 3 hours with the outside temp at 95 AC blasting and I never over heated. I'm not sure the scoop does anything.
