My 1995 Maxima seems to not like the plastic engine undercover.

I think this is the third one to come off....
I cannot seem to locate the part number, nor what Nissan officially calls it.

Is it in the FSM, what section/page?

Also, any tips on installation to keep it on better?

 

Im not sure what you are talking about. Possibly the splash shields????

 

ah ha i think you nailed it!
searching that found me this:

ug what a rip-off. I wonder if there is a good way to zip tie this on better, although that eventually fails too

 

they are dealer parts and expensive unless u pull from the yard

 

get from a junkyard. If you zip tie them on, they shouldnt fall off.

 

any pics of someone's zip tie work???????????

 

It should not be too hard. I'm assuming you can use the old holes in the plastic and you could drill out some new little holes to zip tie through.

 

It's supposed to be bolted up with either 8 or 10 mm bolts.
Perhaps thats the reason you keep loosing them.
