Oil Pump for BYD Song L DM-i and more, OE 12798664-00

Several BYD models share this reference, so reading across from a model name alone will catch you out. Go to the fitment table on this page and match your model with your build year, then compare OE 12798664-00 with the number on the pump currently fitted. An oil pump is not a part you want to find wrong once the engine is open. If your car is absent from the table, or you cannot read the old marking, put the details to us on the quote route and let us confirm the reference first.

If your old unit shows the second of those, you are still looking at the same item. Check both before you conclude anything. Markings on a pump body sit in awkward places and are often masked by old oil, so clean the casting and look again in decent light. Where neither reference appears, send us what you can read from the body with your model and build year, and we will match it here.

Delivery time is confirmed with your quote. Once the parcel is with you, open it up straight away and check the pump has arrived undamaged before you put it aside. Stand it next to the old pump before fitting to confirm the housing and mounting points line up. Should the timing be tight because the car cannot be driven, tell us on the quote route before placing the order.

Metal is the material for this pump. For you the practical points are storage and handling. It comes new, and it should be kept boxed until the day of fitting. Keep it clean inside and out. No casting or alloy specification is quoted for this reference.

This part sits in the engine bay, within the oil circuit of the engine itself. That is deep work rather than a roadside job, and on most jobs of this kind the surrounding assembly has to come apart before the pump is reachable. We do not publish a fitting procedure and none is included. Settle the fitment question against the table on this page before ordering, then have your workshop confirm what else they want to renew while they are in there on your particular build.

For this reference we list the Original/Genuine part made by BYD and nothing in the Aftermarket tier. That is a sourcing position on OE 12798664-00 rather than a comment on quality. When a second supply route exists for a part, both tiers appear together and you choose between them. Here only one is available, so there is nothing to compare against. This pump is also handled under restricted transport rules, so use the quote route on this page with your model and build year and we will take it from there.
