What lurks beneath the cowl... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

68CST327 · 05-10-2003, 09:04 PM

Wow. After removing the cowl today, I was shocked at the amount of dirt and debris in there. I knew it was clogged up, but I didn't know it was that bad. I would estimate about 60% dirt and 40% leaves and twigs. I guess 35 years outside and about 18 of them parked under an elm tree will do wonders.

So are there any interesting stories anyone wants to share? Find any hidden treasures, or other surprises under your cowl?

Blue_71 · 05-10-2003, 09:15 PM

found a 3/8 wrench in my 4x4s cowl, 2wd looked like yours though

gr8scott51 · 05-10-2003, 09:21 PM

What did I find? More rust. Rusted out seams from the windshield to the floorboard.

lotik · 05-10-2003, 09:30 PM

if you shave it that wont happen again..heh

Warbones · 05-10-2003, 09:42 PM

I didn't realize there was that much room to hide dirt and stuff. That will be one of the things I will clean out. Do they make a screen for that?

lotik, have you shaved your cowl yet? Got pictures? Got suggestions on how best to do it? Mine has been hanging from a nail in the garage for so long I almost forgot I had one. ebfabman was starting to work on one for me but he had to set it aside to work on his how-to videos. I'm starting to get close on needing it done but I'm kind of wary of my welding skills for so much that has to be done on the cowl.

I didn't find anything other than pine needles and dirt........I mean nothing,no paint,no metal,nothing ,just huge gaping holes looking into the floorboards!!!!

Riveted1 · 05-10-2003, 10:41 PM

Hey Warbones, they do make a screen for that. You can get them in black or stainless, I think. Mothertruckers, GMC Pauls, Ricks, Brothers, etc. probably carry 'em. That's one of the things on my list for sure!

Jason71k10 · 05-10-2003, 10:43 PM

i think they do make a screen for that. I made one out of the nylon screen for a storm door. You can buy it in rolls at any hardware store.

krue · 05-10-2003, 10:50 PM

I am scared to look under mine. I gotta break down and start cleaning it up just to see how much work it's gonna need.

Warbones · 05-11-2003, 12:11 AM

I will be putting the screen on my want list as well.

*Gee_Emm* · 05-11-2003, 01:16 AM

Its time for me to preach.

Flush out your cowls and other crap collecting areas regularly!

Take a garden hose and run water in these areas until it flows nicely.

The areas include doors, front fenders and the cowl, they all have little slits in the bottom of them that are supposed to be drains. Keep the drains clear!
Do this at least yearly!!!!!!

Also while your at it flush out any other areas on the truck that crap could collect.

Only you can stop rust! :p

Ok Im done :p

yellowgmc · 05-11-2003, 01:31 AM

actually the cowl is the one area on my truck that hasn't given me any trouble. it's very clean and no rust.

73stepside · 05-11-2003, 02:58 AM

mine had a thin layer of caked on dust. not much in there.

**BIG ORANGE** · 05-11-2003, 12:20 PM

I just got 2 cowl trash covers from LMC for 24.95 well worth it!

Hutch · 05-11-2003, 12:51 PM

Both of my trucks had a big glob of sealer on the drivers side inside the cowl.
It looks to me as though the person responsible for putting the sealer on the cab joints had a habit of setting the sealer gun down after this process and the tip of the device had a little sealer left on it which made it way onto the metal inside the cowl.
not sure if this was particular to an assembly plant or whether on not it was a universal thing.
Maybe we should run a poll to see who has this and where their truck was manufactured.

Have fun

Dads72 · 05-11-2003, 05:17 PM

While the cowl is off, check out your antennae (sp?) and wiper motor.

*Gee_Emm* · 05-11-2003, 06:16 PM

The wiper motor is on the inside of the cab.

**passthebuck** · 05-11-2003, 06:33 PM

Not in a cowl BUT I bought a '71 fender from a local bone-yard & it had a big filliting knife down inside it. I'll get a pic of it one day...

Dads72 · 05-11-2003, 07:36 PM

Thanks Gee_Emm
My wiper motor is shot, and I was told the cowl had to come off to replace it.
Did you save me some grief?

Don't want to remove the cowl if I don't have to.

*Gee_Emm* · 05-11-2003, 08:07 PM

Well the linkage is on the outside and is attached to the shaft of the wiper motor but the entire motor is behind the dash and comes out that way.

Blue Beard · 05-11-2003, 08:31 PM

I believe LMC has the screens............

Don't know if I'd want to reach in there.......too many rats nest...........

gr8scott51 · 05-11-2003, 10:34 PM

My insurance says my truck has to stay in a locked garage, so I don't have to worry about keeping the drains open - I wish the PO had! lol Had some professional pics taken today, I'll try to show off when I get them. Mine doesn't compare to some on this board. Scott

YES do this, listen to Gee_Emm...if you don't (like my p/o didn't), then this will happen:

I had two dead rats in my cowl area. How nice it was to see this! They make two kinds of Cowl Trash guards: Stainless steel and painted black.
