FAQ
Q: How do I confirm this ignition coil fits my Kohler engine?
A:Check your engine model number on the identification plate. This coil fits Kohler CH18, CH20, CH22, CH23, CV18–CV23, CV620–CV730, and SV710–SV830 series engines. The OEM part number it replaces is 24 584 45-S, and it also cross-references to 24 584 01-S and 24 584 04-S. If your engine uses part number 24 584 36-S for 22-25HP models, note that this is a different ignition module variant.
Q: What are the symptoms that indicate the ignition coil needs replacing?
A: Common symptoms include the engine being hard to start, running on only one cylinder, misfiring under load, or a complete no-start condition. If the engine starts but runs poorly or cuts out, a failing ignition coil is often the cause. Some users have also experienced intermittent ignition related to grounding issues with aftermarket coils.
Q: Is there a difference between OEM and aftermarket ignition coils?
A: Yes. Genuine Kohler OEM coils are manufactured to exact specifications and are recommended for guaranteed compatibility and reliable operation. Quality aftermarket coils offer a more cost-effective alternative but may have minor differences in fitment or grounding configurations. Some users have reported that aftermarket coils required modification or disconnection of the white grounding wire to function properly. For professional use, OEM parts are often preferred.
