Detailed Description

Delphi brings OE heritage and application knowledge to the CZ20005 distributor, drawing on more than a century of original-equipment experience. This distributor is engineered for select Chevrolet and GMC full-size truck, van, and Suburban applications from 1996 through 2000, including Chevrolet C2500, C3500, K2500, K3500, Express 3500, C2500 Suburban, K2500 Suburban, and P30, as well as GMC C2500, C3500, K2500, K3500, Savana 3500, C2500 Suburban, K2500 Suburban, and P3500.

This part cross-references WAI DST1878 for the same application.

What This Distributor Helps Address

• Hard starting caused by distributor wear or internal ignition signal issues
• Misfire concerns related to cap, rotor, or tower wear
• Rough idle from inconsistent spark distribution
• Intermittent ignition performance on computer-controlled GM V8 systems
• Service replacement needs for aging Chevrolet and GMC ignition components

Installation Notes and Tips

Verify engine and connector style before installation. The CZ20005 uses a 3-pin sealed connector, includes horizontal HV towers for V8 applications, and routes spark through wire sets from the distributor to the plugs. The ignition coil wire and ignition coil are not included, so confirm those components separately during diagnosis and reassembly. Follow the vehicle service procedure for timing and ignition system setup after installation.

Quality Assurance

Delphi builds aftermarket ignition parts with OE experience and original-equipment engineering knowledge. The CZ20005 is designed as a replacement distributor for the listed Chevrolet and GMC applications, with the cap and rotor included for service convenience.
