1942 - 1947 Chevrolet Shop Manual



Replacement operations are the reverse of the foregoing. Front Door Ventilator Glass Removal 1. Using an oil can or similar means, squirt gasoline on the glass filler all around at the glass channel or frame to soften the old seal. When the seal has softened, remove the glass from the channel. 2. Thoroughly clean the inside of the glass channel with sandpaper, removing all rust, etc. Installation 1. Using new glass channel filler, cut the piece to be installed two inches longer than necessary for the channel. Place this piece of filler (soap-stoned side of filler away from glass) evenly over the edge of the glass which will fit in the channel. The extra filler extending beyond the rear edge of the glass should be pinched together to hold it in place during glass installation, Fig. 32.	This will enable the glass and filler to slide freely into the channel. Push the glass with the filler around it into the channel until it is firmly seated, as shown in Fig. 32. After the glass is firmly in place, the oil softens the filler, causing it to swell, thereby making a perfect, watertight seal. Trim off the excess filler material around the channel and at the ends of the channel. It takes 24 hours for the oil to fully affect the filler, therefore, water-leak tests should not be made before this period has elapsed. Sedan and Coupe Rear Quarter Ventilator The rear quarter ventilator on sedans and coupes is of the sliding ratchet type which permits locking in 6 separate positions, the maximum opening being about four inches. Removal 1. Place ventilator in closed position, remove the rear quarter garnish molding and untack the trim at the window opening. 2. Remove the three screws holding the ventilator and mechanism to the quarter inner panel.

	3.	Tip the ventilator assembly inward at the top,
	lift it up and out, Fig. 33. Replacement operations are the reverse of the foregoing; however, prior to tightening the frame attaching screws, the regulator should be set in the extreme forward position, and the glass held securely against the seal in the front of the opening and outer panel weatherstrip. Rear Quarter Glass-Town Sedan Removal 1. Remove the rear seat cushion and seat back cushion. Remove the quarter window garnish molding.
Fig. 32-lnstalllng Ventilator Glass NOTE-One side of this filler (the outside of the roll) is soapstoned. This is the side which goes into the metal channel. This glass channel filler is serviced in two thicknesses-.032" and .047"-to permit selection of the proper thickness so the glass may be installed without the use of special tools. 2. Brush the inside of the metal glass channel freely with ordinary SAE No. 10 engine oil.
