Inner fender dust shield

Can anyone tell me there is a function to these inner fender dust field besides its intended name. Was told it helps with cooling. Is it something u should have on the car?

Re: Inner fender dust shield

The only time I've seen a 'dust field' around the inner fenders is when I was running down a dirt road.
Anyway, IMO the dust shields are just that. They are intended to keep dust out of the engine compartment. I don't like them and remove them as soon as they crack or tare. I like being able to see the upper control arms when I'm showing the truck.
I wouldn't put them back on the car/truck.

Re: Inner fender dust shield

Don't know that they would help with cooling. Newer cars have a pretty well sealed up engine compartment to help with cooling. There's so much open space in a Chevelle, don't think that little dust shield would make much difference.

Re: Inner fender dust shield

Do they have a function? let me count the ways...
  • On 67 and earlier cars, Inner fenders provide additional rigidity for the fender structure, and hae a definite effect on the lower door seam alignment.
  • On all Chevelles, they protect various components from rock damage. (e.g. POA valve, blower motor, evaporator suction line, etc.)
  • They minimize the wetting of the underhood electrical and mechanicals, especially for vehicles driven on winter roads. Salt corrosion KiLLS wiring connectors!
  • They support the headlight bucket assembly area of the grille/radiator support, and are a measurable part of the strength assembly of the entire front sheet metal structural assembly.
  • They provide primary mounting support for the weight of the battery via the battery box.
  • They provide attaching points for various hoses, wiring, and the receiver drier on AC cars.
  • They reduce road noise in the passenger compartment.
  • They reduce turbulence in the wheelwell airflow and engine compartment at high speeds, and (of course)
  • they reduce dirt and dust incursion in the engine compartment.

So yeah, they have a function. GM didn't put a sticker on a car without having a functional reason.

Can you live without the above? Well, it is your car. I've done it both ways. I would never these days run one without them on MY car, but MY car has air and is a comfy cruiser, not a race car.

That's the beauty of living in America, right? You can still remove your inner fender panels and the government can't say darned thing about it!

Re: Inner fender dust shield

Oops... I see you live in Canada. I apologize for my presumption.

Not sure of the legality of removing them up there...

Re: Inner fender dust shield

He's asking about the inner fender "rubber skirts" that shield the upper a-arm. I have always wondered about how they installed them thru a steel inner fender with.... "staples". Really- staples? I have a set here now that I just cant imagine the stapler big enough to punch thru a steel inner fender. To the original post: I think thats all they were is a loose flexible "curtain" that helped keep contaimanents, water out of the engine bay. Anybody know how or what to use to staple these dudes- jeez, gonna piss off my secratary if i screw up the office stapler trying this:

Re: Inner fender dust shield

We used a drill bit to punch the holes then used mig wire to make our own staples. I think it was stainless wire so they won't rust but don't quote me on that

Re: Inner fender dust shield

Same here... I purchased the kit that included staples and I used a drill to make the holes for the staples to go through.

Re: Inner fender dust shield

The "dust shield" may help keep some dust out of the engine compartment.

I suspect the main reason is to reduce the amount of water on the engine while driving in the rain.

That is not much of a problem with the trailer queens and car show princesses around now.

Wink Re: Inner fender dust shield

I agree with Verle, that the shields are there to keep water from splashing into the engine compartment, possibly shorting something that could cause the car not to operate properly, causing a warranty issue that would cost Chevy some $$$.

I met a guy at Chevelle-a-bration in 2005 who worked at the Fremont or VanNuys plant who had that job. The machine was like a large punch press that would ram the hardened staples through the fender and shields and fold the staples when he stepped on a treadle. When he came to work there was a pile of inner fenders that he was to put the shields on, and when the pile was finished he was done for the day. If the job was finished before quitting time he'd go to another place in the plant and kill time until the shift was over.
This guy is "Mr64" here on Team Chevelle. He had a super-cool '64 two door wagon with a Vista Cruiser top on it. Dave hasn't been here in a while, I hope he's doing well.
