I am getting parts off of a 52 F2. The cowl vent is complete and appears to be in good shape.
I am more familiar working with 53-56 trucks. So i am not sure how to remove the cowl vent. I removed the 4 screws from the front of the vent on the outside. I can see 4 other screws on the back side when I look up at it under the dash. How do I get them out?
Also is the handle attached to anything under the dash? And does the whole unit lift out through the vent hole from the outside?
Thanks. These cowl vents are a lot different than the vent on my 54.
Thanks, that helps a lot... but still have this question: how do I get the four screws out of the back of the vent? from the top like I did for the front of it?
They are a pain in the butt to remove but even worse when you're installing it back into a freshly painted cab.
Last Saturday, I tried again to get the cowl vent off. I could not access the 4 screws at the back of the vent. Excuse me for being so thick but how do I get to them if the vent door covers them when closed and pretty much covers them when open?
Abe, Here's a tip for you. The screws in the lid don't have to come out all the way. Just loosen them a bit and you can slide the screw heads out through the larger part of the screw holes in the hinge. I knew this but still forgot once and in the process broke off a head or two, when I didn't have to.
Loosen the 4 hex head screws that hold the lid on with a 5/16 open end wrench, slide the lid sideways a bit and remove. Then, push the rubber seal back and remove the 8 Phillips screws around the perimeter of the vent assembly.
Now, crawl under the dash and remove the main 1/4 bolt that provides friction to hold the vent open and closed. It’s the one on the left with a spring on it. You first remove the locknut, then back the bolt out of the friction “wheel” that’s behind it. Pay attention to the order of parts so you can reassemble someday.
With the bolt out, the vent assembly will pivot freely, you can then wiggle it out through the cowl opening. If you remove the seal first, you’ll have a bit more clearance to first lift the front of the assembly, rock the passenger side out of the hole, turn 90 degrees, and remove the whole assembly.
It doesn’t look like it will come out, but I assure you no prying, hammering, or other brutal techniques are needed to remove it.
