I Can See Clearly Now

Windshield Defroster for a CJ-3B


FrontJohn Hubbard took these photos after sandblasting the manifold of his Willys original equipment defroster.

The first photo shows the side facing the driver. This example lacks a second indentation for a hose opening on the right-hand end, as seen on the defroster in a 1963 CJ-3B (50K JPEG).

Bill Oakes took a larger photo which shows the crinkle paint finish, and the second indentation.

BackThe second photo shows the side of the defroster facing the windshield, and the mounting brackets.

A reproduction of this manifold is now available from Herm The Overdrive Guy.


If you don't have the other parts of the original defroster, it shouldn't be too hard to build a heater outlet, similar to this apparently original one on the left duct on Bill Glasford's '57. See a larger copy of the photo (40K JPEG), and a photo of the entire heater (50K JPEG).

If you have a 2-1/2" hole in the dashboard above your steering column, that's where the original hose was routed through the dash. See a photo by Adam Charnok of a 1963 interior including defroster (50K JPEG).

Defroster manifoldJoel Kamunen built this defroster manifold out of 1-1/4" PVC tubing. He says, "It clears the windshield off quite nicely. I spaced the holes about 2" apart and may try different hole sizes to see what works best, but it's a great improvement from the stock set up."

See a larger copy of the photo (50K JPEG). Thanks to Joel for the photo. See why his 1954 CJ-3B has to have a defroster, on the Enhancing F-head Performance at High Altitude page.
