Front belly pan Plastic shield.
 

What do most +00 guys and gals do in the summer with this belly pan :?:

I have mine off right now and am considering leaving it off for the warmer summer months.
Do you think there are benefits to leaving it on :?:

I have it off on my 95, but was told by a shop that I should put it back on as the slots in it direct air into the engine compartment and it helps to push the hot air out the back of the engine. I thought that without the pan it would work better, and when I told them my thoughts they said that it doesn't really flow the engine, but rather that it swirls up and right back out the front. Kinda messed up and I didn't really bite.
Again, this is on a 95, so it could be different with the 00+.

There are no slots or vents on +00 pans. I think it would benefit to leave it on in the winter or rainy days but when it is dry and hot, it should be better to have it off for engine compartment ventilation.

Anyone else....who has a +00 model. :feedback:

Belly pan? Am I missing a part? I want a pic.

Actually it's upsidedown in the pic, but you can see how it fits directly below where it is.

Hmm, what's a 92-99 pan look like?

:? Get down underneath your car and look. :lol:

I know I don't have anything resembling that part. That looks like it would attach to the lower edge of the bumper cover, but the only thing I've got down there is the air dam that I had to get and install last fall. I didn't even used to have that.

Well I guess the pre 00 Bonne's don't have one.
So that might answer my original question. If it doesn't matter for you it should't hurt me to leave it off.
It does create a nice shield from water in the wet weather.

There might be some slight aerodynamic benefits at 150 mph. ;)

The angle of this pic sucks, but you can see those plastic push pins, and the black air dam. Well, the push pins don't hold anything and there are empty mount points on the front top lip of the air dam. And there is 6 inches between the dam and the bottom of the bumper cover.

My dam spans between the bumper cover and the engine sub frame. Fills a gap of about one foot.
Yours looks quite a bit different.
Maybe you used to have a dam there but it was removed. :?

If you remove the airdam lip and the cover, the car will tend to overheat. I broke the airdam lip while parking and it also ripped the lower cover, so I left them off. The engine temperature started to creep to higher temperatures. Then I remember that many moons ago, when I had my late model Pontiac T/A, the airdam lip also broke and I left it off. The car started to overheat during traffic stops.
I asked a friend that used to work at the GM proving grounds and he told me the airdam and the lip are designed to flow air directly to the radiator area. He also said than when the car sits idling, like in traffic, they also redirect the air the fan are sucking. I replaced the airdam lip on the T/A and the problem went away.

This pan fits behind the air dam and radiator so it shouldn't matter.

It's a splash guard eh? Hooks on at the bottom of the radiator support right?




I have also heard of this.

If we are on the same wave length here, PDad took ours off last year at the WCBF to install the new fans (thanks again Bill) and he just put it back on last week. I had forgotten all about it. You really don't see it, and it didn't affect Bone Evil's performance ;)

During the trans cooler install? I think that was the lower airdam skirt, which is just forward of the piece Paul is talking about.

So what years do have this?

I know that the 87-91 doesn't and if memory serves the 93 doesn't either...

94 I am not sure of...

My 95 and my Cousins 95 both have that black air dam from right under the radiator to the subframe

No Bill that is exactly the same piece I am talking about.

PMom, why did he put it back on?

To be honest with you Paul, I have no idea :oops: I was at work, and came home to find him working on the car. I will ask him, and get him to post.

92-99 SSE's and SSEi's (unsure about the SE/SLE which is rather embarrasing since I own one, but I believe it's similar) only have the black plastic lower skirt just below the front bumper, and a little to the rear. This piece (on the 92-99) serves no cooling purpose, but does provide some handling differences at high speeds (over 120mph). Trust me on that one.

What are all those push pins for you can see in my pic?

i've run both ways on a 95 and 97 SSEi's.. have not found any differences in temp either way.

.....and so mine shall remain off.

Looking more and more like the whole family will be going to WCBF so I won't be going over 120 mph. 8)

Hrm, if its a plastic part, its called a Lower Air Dam, and on G body Auroras it is integral to regulating engine temperatures. I've had mine come off, the little plastic tabs that hold the dam into the lower skirting cracked. I was going to forget about it, but once I researched how it affected engine cooling, it went back on.

Anyone that experiences hot running engines in Auroras, its sometimes that shield there.

Then again, I'm not sure how it works on the Bonnevilles.

Yes, upon closer inspection, I can see what you mean Jim. The lack of support that this "Lower Air Dam" provides when in place would, expose the inner wheel well front extensions; and front bumper lower air spoiler (that does most of the directing of air into the radiator) would lose ridgidity and possibly crack with the extreme wind forces at higher than the posted limits :twisted:
:slomo:

adam said he blew the air damn off of my car at the track, and it took a fenderwell with it... without it the bumper is extremely weak, and i still have not replaced it :duh:

wanna sell yours ;)

I'm putting it back on. :shock:
