How to Replace a Rubber Windshield Gasket on a Chevy Truck

Updated April 17, 2017

The rubber gasket on the windshield of your Chevy Truck is used to help secure the windshield in place. Over time, the gasket can become worn and damaged which jeopardises the stability of your windshield. If this occurs you should remove the windshield from your truck in order to replace the rubber gasket. You can pick up all the tools you will need for the job from your local auto parts store.

Depending on the age of your Chevy truck you may wish to put a dust sheet on the hood to help protect the more vintage paintwork. Use a sharp blade to carefully cut away all the rubber seal which is found around the edges of the windshield. Pull the rubber away from the windshield as you cut it. Properly discard it in the trash.

Enter the driver's side of your vehicle and gently press the windshield out of the frame. Have someone on hand outside the vehicle to help you lift it out.

Apply a thin layer of windshield sealant around the edges of the windshield. There are many sealants available all of varying prices. You don;t want something too expensive for your Chevy as all will do the required job. The Cr Laurence CRL Windshield Sealant is a good, affordable option. Attach the new rubber gasket to the bottom of the windshield. The heavy part of the gasket should be on the inside of the windshield and the slit on the outside.

Tie a nylon cord around the outer groove of the windshield. Lift the windshield in to place. Press the windshield against the frame for a few minutes to allow the seal to set.

Pull the nylon cord across the windshield from inside the vehicle to allow the rubber lip to set in place. Clean the windshield and dashboard to ensure no debris has got into the vents or electrical components.
