EP-1639A Electronic Distributor for Chevrolet Astro Van 4.3L V6 — Variant (Replaces 10496786)

The EP-1639A is a variant-configuration electronic distributor for the Chevrolet Astro and GMC Safari van equipped with the 4.3L V6 TBI engine. The Astro/Safari was the most popular mid-size passenger van in the US throughout the late 1980s and 1990s, and the 4.3L V6 in rear-wheel-drive configuration accumulated substantial mileage in both family and light commercial service. Distributor replacement is a routine service item on these high-mileage vehicles.

The 'A' suffix on EP-1639A designates a connector or housing variant within the GM 4.3L V6 distributor family. The Chevrolet Astro and GMC Safari van may use either the EP-1639 or EP-1639A configuration depending on the production year and engine management specification. Verify the OEM part number on your existing distributor (10496786 or 10467353 for EP-1639A) before ordering.
