The EP-1829 is a complete electronic distributor for Cadillac vehicles equipped with the 5.7L V8 engine across the Fleetwood, Brougham, DeVille, and first-generation Escalade platforms. Cadillac's transition from traditional HEI ignition through TBI and EFI systems in the late 1980s and 1990s produced several distinct distributor configurations tied to specific model years and engine management systems. The EP-1829 addresses the most common Cadillac 5.7L V8 distributor applications in this era.

The GM 5.7L V8 used in these Cadillac applications shares the same basic distributor architecture as the Chevrolet and GMC C/K truck applications of the same era, but the exact Cadillac fitment requirements -- connector configuration, cap style, and housing specifications -- require verification against the OEM part number on the existing distributor. The EP-1829 replaces OEM 10458104, 12570425, 93441558, and the aftermarket cross-references 1103952 and 84-1829.

Ships complete with distributor cap and rotor. Compatible with the factory GM ignition module and coil.

Installation guide

Disconnect battery. Mark the position of the distributor rotor and housing alignment before removal. Disconnect the electrical connectors and vacuum advance hose if present. Remove the hold-down clamp and withdraw the old distributor. Lower EP-1829 into position matching your reference marks exactly. Reconnect all electrical connectors. No timing adjustment is required on fuel-injected GM applications of this era -- the PCM controls timing. Verify OEM number on old unit matches EP-1829 cross-references before installing.

Frequently asked questions

What are the symptoms of a failing GM EFI distributor?
Common failure symptoms for GM EFI distributors of this era include intermittent no-start conditions, engine stalling at operating temperature, erratic idle quality, loss of power under acceleration, and check engine codes related to the distributor reference signal or cam position sensor. The Vortec-era distributors (1996-2002) are particularly known for plastic housing cracking or warping from heat cycling, which allows oil or coolant contamination of the optical or magnetic pickup sensor inside the housing. The LT1 Optispark distributors (1992-1994) are known for moisture infiltration that degrades the optical sensor window, typically producing a characteristic hard cold-start condition that improves as the engine warms up.
Does the EP-1829 ship with the cap, rotor, and all necessary sensors?
Yes. The EP-1829 ships as a complete plug-and-play assembly including the distributor body, distributor cap, rotor, and all internal sensors required for operation in the listed applications. For Optispark LT1 units, the optical sensor assembly is included as part of the complete distributor. For standard EFI units, the magnetic pickup and cam position reference sensor are integrated into the assembly. No additional ignition components are required beyond the standard ignition module and coil already present on your vehicle.
How do I verify the EP-1829 is the correct distributor for my Cadillac?
The most reliable verification method is to check the OEM part number stamped or labeled on your existing distributor housing, then cross-reference it against the EP-1829 OEM references: 10458104, 12570425, 93441558, 1103952. If your existing distributor shows any of these numbers, the EP-1829 is the correct replacement. For first-generation Escalade applications, also verify the engine is the 5.7L Vortec (not the 6.5L diesel or other engine options). For Fleetwood Brougham applications, verify the engine is the 5.7L (350 CID) and not the 4.9L or Northstar V8.
Do I need to reset the timing after installing this distributor?
For most GM EFI applications of this era, the distributor does not require timing adjustment after replacement if the engine is set to top dead center (TDC) before the old distributor is removed and the new unit is installed in the same position. Most 1987-1995 GM TBI and EFI applications use a computer-controlled timing advance that does not require a timing light for replacement -- align the distributor housing marks and the rotor to the same position as the original unit. For 1992-1994 LT1 Optispark applications, the base timing is not adjustable in the field; the Optispark provides a crankshaft-referenced timing signal and the PCM controls all timing advance. Consult the factory service manual for your specific vehicle year and engine for the correct installation procedure.
How do I order the EP-1829 for export or wholesale?
EP supports single-unit orders for market sampling, carton quantities for repair shops and parts counters, and container-volume wholesale orders. Standard production lead time is 15-30 days. OEM branding and private-label packaging are available for qualifying volumes. Contact our team via the inquiry form or WhatsApp for pricing and availability.
