Cowl repair

I notice some water dripping off the bottom of my dash when I drive in the rain. I am sure there must be some holes in the cowl somewhere. The rest of the truck is in very good condition. How difficult is it to fix the cowl? Do I have to drill out a million spot welds to fix it?

I would check the drip rail and firewall for any areas that might be leaking first,

could be comming from a wire loom or cables

Clean the crud out of the lower cowl, The drain gets blocked by debris and water will run into the cab.

Also check the leather gaskets under the wiper pivots. These rot over time and alow water to enter the cab.

How do I clean out the cowl? Is there an access panel?

There are access holes, but they are behind the finder, here is a pic, the lower red circle is where the clean out is, the others are access holes to the cowl area

You can also get in there from the vents in side the cab. the early oval cable ones or the later triangular manual ones.

Bill is that your yellow truck or a spare?

I have already cleaned out everything from the vents inside the cab. I'll try the upper access hole. Water is dripping from the front side of the dash, just below the radio.

A common area for leaks is the bottom corners of the windshield frame under the weathstripping. But those drips show up at the corners of the dash.

Another short-cut for cleaning out the cowl requires a little patience, but if you have access to an air compressor, you can blow most of the crap out (after it dries out).

When i replace the firewall in my 66 i found a rust hole one the drivers side just under the small pilot hole in the lip of the cowel were its spot welded to the fire wall. To clean mine out i used an air hose and blew as much as i could toward the upper access hole and stuck my shop vac hose in there to suck out the debris. Good Luck. Justin

Center leak is the top bolt for the wiper motor bracket. It is in the base of the open cowl where as the two lower bolts are in the firewall.

easy fix is to remove the bolt loosen the other two and squirt silicone sealer in the hole and around the bracket.
