Ignition Coil — OEM 3705100E10

OEM reference 3705100E10 is a catalogue lead for an ignition coil, not a Great Wall-wide application. The collection currently links one Bosch F01R00A025 candidate and local cross-reference data associates the OEM number with Great Wall. Confirm the exact VIN, engine code, production date, market version and complete marking on the installed coil before treating that connection as relevant to a vehicle.

Keep the final E10 and the full number order. Search systems may add spaces, hyphens or letter-case changes, but a shortened match can merge unrelated reference families. Build a provenance record showing where each link came from, whether it is an OE number, aftermarket cross-reference or application listing, and whether any supersession runs forwards, backwards or only under stated conditions. One shared candidate does not prove that 3705100E10 equals another OEM reference.

The local Bosch F01R00A025 row includes a 14 V rating. That is a product attribute, not an instruction to feed 14 V to an unknown terminal and not proof of pinout, dwell strategy or fitment. The vehicle’s engine controller may switch primary current directly or command an internal driver. Connector keying, pin function, mounting, boot depth, spark-plug terminal and thermal environment all need to match.

Before removal, save confirmed and pending fault codes, freeze-frame values and misfire counters. Check battery condition, cranking and charging voltage, coil supply and grounds under load, connector contact, plugs, plug wells and insulation. Include injector operation, compression, valve timing and intake leaks. A cylinder misfire records incomplete combustion; it does not name the failed part.

Use insulated, vehicle-appropriate test equipment and never create a loose spark near fuel vapour. Work with the key controlled and hot surfaces cooled. Fit only after the reference and circuit evidence agree, then validate cold start, idle, acceleration and hot restart. Stop for a flashing engine lamp, strong fuel smell, violent shaking or major power loss because unburned fuel can overheat the catalyst. MOT emissions and warning-lamp checks do not authenticate an OEM cross-reference.
