    Plastic Belly Pan--do I need this thing?

    Driving today when I hear a whining, scratching noise that sounded like I hit a skeleton and was dragging it at 50mph. Plastic belly pan (the rear-ward one that you remove to do an oil change) had somehow popped loose on the front end, and the thing was scraping along like a snowplow.

    Other than serving to keep the bottom of the engine a little cleaner (well, and the incredible improvement in aerodynamics ) is there any reason for me to figure out how to re-attach this thing?


    thanks

    Mine is destroyed but I plan on getting a new one soon. The one that attaches to the bumper cover on mine got destroyed too, so I need that also. My theory is, if it came from the factory, it's there for a reason. Especially the front one that attaches to the bumper cover. Last thing I need is my wife to pull up on a parking block and have her rip the front end off when backing out.

    The rear one (as you point out) is mostly for aerodynamics. Mileage. The front one braces the bottom edge of the fascia. Without it the fascia will flex, over time creating stress cracks in the paint.

    I hung mine on the wall the first time I changed the oil and it's still there now.. I'm not sure how much it helps with aerodynamics, but I've never gone over 150 mph..Maybe it helps after that..

    ^^^ DIng! ^^^ and...

    if you have a fumoto drain plug it protects that
    it keeps the underside cleaner
    I suspect there is a very good chance that air flow through the engine bay will be impacted to some extent. Counter-intuitive but most likely the case. Turbulence is always a negative.
    There are a whole 4 bolts (that go into clip type nuts) that hold that thing on. Like Anguish said, the front edge goes on top of the rear edge of the front pan. If it's still serviceable put it back on. If it's trashed you could go either way but better to have one on there than not.

    This. At 150+ without that front pan Bad Things will happen to the fascia.

    AND it only costs $9.63 to ship to Kallyforrrnia...

    Thats incredible. I've had to buy these from the dealer in the past and shipping has been more than the damn part itself, which itself cost a lot more than RockAuto is listing.

    I've ground away two or three on track. With the car lowered big time (small track wheels lowering it even more) that pan provides a first level of protection for the underside of the car. It ain't much but I've trashed belly pans and not scraped the crap out of things like the oil filter (which I have extended thanks to an oil sandwich adapter and oil cooler AND big filter so its just barely behind the cross-member). The belly pan has also kept mass quantities of rocks (the kind you find just off-track in gravel pits) from smooshing themselves all up in the underside of the car.

    Not the most common use, but speaking personally I like to keep them on the car. And I don't really ascribe to the metal ones some people have fabbed as I'm ok with the thing tearing away since it doesn't take anything else with it, being only plastic.

    While we're on the subject. I've been waiting to see how those with rigid belly pans fair over a bit of time. If figure there is a lot of stuff around there that flexes and gives while driving, cornering, etc. I'm half expecting facia failures -- cracks, breakage around the bolt holes, etc. ...and then there is the scenario of bumping up against something with the lower facia with no give behind it.

    If you keep it off at least put the 2 front bolts on & screw then into the cross member & the rear of the front pan It will keep the front pan from flapping around & stabilize it.

    I had been dragging mine for years until finally I ripped the whole thing off going over some railroad tracks. I didn't think much of it until I was cruising for a bit @~110mph and I saw smoke in my rearview mirror. Pulling over I couldn't see anything, but after closer examination I saw that the air coming in through that new opening built up enough pressure to push the plastic inner fenders against the front tires... the smoke I saw was the inner fenders about to catch on fire! I plan on replacing the piece soon, and I am hoping that the links in this thread will result in a good source. Next will be replacing those inner fenders

    Well keep in mind that this is not OEM. It's made by a third party manufacturer. I used Rock Auto to replace my seat heater switch and I can't tell the difference versus the other OEM one but I don't know anyone who has purchased this belly plan to compare the quality.
