Supportable references also connect this assembly to late-model 4.3L, 5.0L, and 5.7L Volvo Penta gasoline engines using HVS or Delco-style ignition-system layouts.

Serial Number Fitment Notice
Fitment may vary by engine model, ignition-system configuration, and production break. Always confirm compatibility by engine model and serial number before ordering. Volvo Penta directs users to identify the exact engine, shield, or drive when locating the correct spare part.
When This Part Needs Replacement
Replace this coil assembly when the original ignition coil or module has failed, is causing weak or intermittent spark, or when troubleshooting points to ignition-related symptoms such as hard starting, misfire, rough running, fault-code issues, or loss of dependable spark under load.
Installation Notes
Confirm the exact application before installation and compare the new assembly to the original ignition component during service. Inspect the related wiring, terminals, coil lead connections, mounting bracket, and surrounding ignition components so the replacement is installed into a clean, reliable ignition circuit. Matching the assembly to the correct ignition-system style is important for proper service results.
Alternate/Superseded Part Numbers
Current supportable references also show 3862167 and 3883158 as related earlier numbers associated with this coil assembly. Cross-reference use should still be confirmed by exact application before interchangeability is assumed.
Parts Desk Insight
Ignition parts can look similar, but coil-and-module assemblies are not generic. Matching by serial number and ignition-system layout is the best way to avoid repeat troubleshooting and make sure the replacement suits the exact Volvo Penta setup you are servicing.
