Oil Pump Chain for BYD Song L & Sealion 05 DM-i, OE 12798666-00

A number of BYD models carry this reference, so treat the model name as a starting point and no more. The fitment table on this page is the check that counts: find your model, then your build year, and see whether the combination is listed. After that, compare OE 12798666-00 with anything readable on the chain or its guide that you are removing. If your car is not shown, or the year sits at a boundary, come to us on the quote route with those details before you buy.

It may well be. This chain answers to OE 12798666-00 and also to 472QA-1011200, so either number can lead you here legitimately. Check your paperwork against both before you assume a mismatch. Chains themselves rarely carry a legible number, so the reference on an invoice or on the old packaging is usually the better evidence. If nothing you have lines up with either, send what you do have plus your model and build year through the quote route and we will identify it.

Delivery time is confirmed with your quote. When the parcel arrives, check it is intact before you sign for it, and have the old chain to hand so you can compare the two before you fit the new one. If anything looks amiss, get in touch through the quote route on this page before you go any further with the job.

Metal is the material for this chain, with nothing further specified. The useful implication is about care rather than specification. It is supplied new and should be left in its packaging until fitting, since a chain that has been dropped or knocked about on a bench is not worth the risk once the engine is closed up. The packaging details for it are shown on this page. No pitch, length or alloy figure is given, so none should be assumed.

The position we offer for it is the engine bay, driving the oil circuit inside the engine. It is not a component you can inspect without dismantling, which is why most people replace it while the engine is already open for something else. No fitting sequence is published by us and none comes with the part. Deal with the fitment check on this page first, then let the workshop advise on timing, because doing this job alongside other work in the same area usually saves paying for the same access twice.

We list the Original/Genuine chain made by BYD and hold nothing in the Aftermarket tier against OE 12798666-00. When a reference has two supply routes behind it, both tiers show on the page and the decision is yours to make. This one has a single route, so a single version is shown. If you would like us to look further for an alternative reference, ask on the quote route with your model and build year. That is also the route you need for this item in any case, given its transport class.
