2013 Chevrolet Cobalt 6T30/MH9 axle seal numbers: what the EPC confirms

Exact EPC rows bind 24230682 and 24230715 to a 2013 Chevrolet Cobalt JX69/L2C/MH9/FV1 context, but those exact rows do not print side tokens.

For a bounded 2013 Chevrolet Cobalt JX69 / L2C / MH9 / FV1 application, exact EPC evidence places 24230682 and 24230715 in the axle-seal service context. The important limitation is that the exact Cobalt rows do not print LH/RH side tokens.

24230682: exact 2013 Cobalt application

E647 binds exact 24230682 to JP/JX69, L2C, MH9 and FV1 for 2013. That closes the application at part-number level. It does not, by itself, prove the side because no side token is printed in that exact row.

24230715: exact 2013 Cobalt application

E648 provides the exact 24230715 primary row for the same 2013 Cobalt JX69/L2C/MH9/FV1 context. The row prints К КОРПУСУ (“to case”) but no LH/RH token. Under the cross-row rule in E646, TO CASE must not be converted into “left”.

Why the site still labels the pair RH / LH elsewhere

OEProof’s broader fitment table carries 24230682 = RH and 24230715 = LH from independent industry/dealer catalogues, and at least one marketplace source contradicts that side label. That conflict is preserved and worked through on the page that owns the question: 24230682 vs 24230715: which is left and which is right. The narrower point here is different: the 2013 Cobalt exact EPC rows themselves do not print those side tokens. We keep those two statements separate rather than merging them into a stronger claim than the sources support.

Do not turn co-listed numbers into replacements

The 24230715 row also contains a parenthetical group with 24257030 and 24260764. That is a same-position co-listing, not a new per-number Cobalt application and not proof of unconditional interchangeability or supersession.

Practical ordering rule

For a 2013 Cobalt, use the exact OE and vehicle/RPO context together. If side is commercially important, preserve the RH/LH label together with its evidence grade and verify the physical supplier item before shipment. Send VIN / OE through the RFQ if the vehicle is outside this exact 2013 context.
