General Motors Waterproof Rivets: UPDATE

On the 2017 and newer Chevrolet Cruze, if you read through some of the procedures, like the Rear Wheelhouse Panel Replacement procedure, you may find yourself asking, “What is the waterproof rivet B1 referenced in the installation procedure?” Let’s find out.

If you come across this or another type of fastener you may not be familiar with, the answer can typically be found in the vehicle-specific body repair manual on the ACDelco website under: Body Repair ➤ Collision Repair ➤ Specifications ➤ Fastener Specifications. In this case, the 2017 Cruze body repair manual identifies the Waterproof Rivet B1 as a blind rivet. This document also calls out the correct GM part number for the rivet.

In the case of the 2018 Chevrolet Cruze body repair manual, the outer A-pillar sectioning procedure specifies the use of waterproof rivets B1. The chart listing the rivets is located within The Collision Repair Specifications (Riveting) section. However, the manual is currently being updated to include the waterproof rivet B1 part number. Per our contact at GM, “The B1 Rivet is the correct Rivet part number 13438214 for the A-Pillar the Grip range is 0.5 to 6.5 mm.”
