What part is that and should I be concerned? Can it be replaced?

 

You should have showed me this today. Looks like AC lines? Do you have any pics from further away?

 

I think that they are heater pipe lines.

 

yea looks like heater lines...ac line is in the lower left corner i think.

 

From the 00-01 engine bay pic thread, looks to be common issue.

my car has some rust around the engine too, i notice it started rusting after i sprayed it with an engine cleaner the one that you could get in any auto parts store.

I was wondering how you guys have your engine bay so clean.

 

Looks like surface rust...try sanding a section and if it comes off, coat it with something.

 

Its part of the coolant lines. Just sand it down and or paint it.

 

I'll see what I can do. Thanks guys. Tim, I guess I forgot about it and I opened my hood up yesterday and...

 

I've got some rush similar to that, not as bad. I wouldnt worry about it. But like the other folks say just sand the surface down a bit and repaint with some thing resistant to heat and you'll be fine. Probably need to use a small brush to get in there.

 

Mine looks worse. I doubt it's anything to worry about.

 

Worse that MINE? Wow, I feel better now. Thanks Sam.

 

No problem, Jason. I doubt you lose heat in the winter. It's not like it's a German car.

 

Hahaha 10 char

 

It looked worse then that on my 4th gen Maxima as well.

 

yeah, mine's worse than that...i don't think it's that big of a problem.

if you want to keep your engine bay rust free, just sand it and paint it.

 

sand it and add some anti rust product if there is one...

 

thats normal. you get condensation on it that then dries quickly. rust develops over time

 

i have that also...nothing to worry about its just from the condensation drying like soonerfan stated.
