Cowl vent drain

Water enters around pick panel vents when parked in hard rain. Just enough to dampen floor near door sills.

Replaced kick panel vent door seals. Vent doors now shut tight and seal out air…looks like water seeps around vent mounting.

How does air (and thus water) flow from outer cowl vent (by wipers) to kick panel vent area?

Is there a cowl vent drain path or tube out bottom or to engine bay (mine perhaps plugged)?

Probably unrelated but I just solved my leak generating there by replacing the windshield wiper motor rubber gasket. It was coming down in the center of the cab though...

Yes there is drain holes in the cowl behind the fenders. The orange arrow shows about where the drain holes are on each side. They are know to get cl0gged with leaves and all, then allow the moisture /water to rust out pinholes in that area and they leak there.

I have sseen folks cut a hole (blue square), then patch/seal the damage, then weld back the hole to repair it there.

Re: Cowl vent drain

I just finished repairing mine as described in post above.theres also a sheetmetal deflector spot welded just above the vent opening that's probably rusted away also.

Re: Cowl vent drain

excellent! Thanks....I'm betting years of pine needles and forest duff clogging drain.

Can I access the drain hole under fender without pulling fender?? I'm going in.

Re: Cowl vent drain

You can also remove your vents from the inside and reach into the cowl. Just feel around and pull out the junk clogging the drain.

This is also a great nesting spot for wasps.

Have fun!
