Sierra 18-5516 Delco EST Distributor Timing Tool

The Sierra 18-5516 Delco EST Distributor Timing Tool is built for engines equipped with a Delco EST distributor that cannot be placed in base timing mode using a diagnostic tool. When the distributor's electronic spark timing module cannot be commanded into base timing electronically, this tool provides the mechanical means to lock the distributor in place so base ignition timing can be set correctly.

The tool is constructed from aluminum and stainless steel with a black finish, giving it a compact, durable design sized for use directly at the distributor. Its small footprint makes it easy to keep in a marine engine toolkit alongside other ignition service tools.

This is a genuine Sierra part, engineered to meet or exceed the original equipment part it is designed to work with, and it is backed by Sierra's Customer Satisfaction Warranty.
