Cleaning the krap out of the cowl - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**landy** · 09-22-2012, 08:49 PM

So there's some accumulation of small sticks, dirt, debris, etc. in the cowl area and also behind the kick panel vent doors. I thought maybe sticking a hose in there to try and wash out some of the debris. Maybe an air hose? Any other ideas?

Thanks!

Hands won't fit in between the bars on the cowl area, and I can't fit my hands very well into the kick panel vents. I suppose I could remove the vent doors for better access. I don't want to remove the cowl, though.

So I took the cowl off, got a shop vac n sucked it all out, try that.

the vent doors pop out easy, hands, vac, and air all work. those stainless trash guards that sit under the cowl will help keep the debris out in the future.

i first tryed the shop vac an it worked ok but couldnt get good enough sucktion so i took it off and hands and air hose trust me i just opened my vent doors today i got leaves twigs...a pencil all sorts of thingamajigs in there

Run a water hose down each vent after you remove the cowl and get all that crap out of there! If you don't get it all it will rust. The water won't hurt it but wet leaves and dirt soaking in there will. I cleaned mine out with air and thought they were clean until I ran a bunch of water through them, tons more crap came out!

I'm in the process of cleaning mine out right now. I went as far to take the heater box out of the truck. Lots of stuff up in the fan and heater core also. With the vent doors and that all out. It is pretty easy to clean out. I will reinstall with fresh paint and new seals.

i taped a heater hose to my shop vac and stuck it down and around to get stuff out.

I did that 3 years ago and found a pack of pall malls, and an old drivers license when I helped a friend pick up a truck in Arizona. Arizona trucks don't see much rain, wish I had that problem up here in Washington State...

Looks like they are at least two bolts on each side and several phillips-head screws to get the cowl off? Also need to remove the wiper arms and antennae?

Thanks!

A few pics of when I did mine a few months ago:

Went to Lowes, in the section where they have sheet metal, and picked up some sheet metal screen. Comes in a metal sheet (very thin, but much thicker than normal house/window screen). Had to cut out two sections, one for each side of the cowl. Painted black and (for now) used zip ties to hold in place.

I park under an oak tree (over my drive way) and it sheds a lot. Really helped keep the leaves, acorns and other debris out.
