Exhaust Valve for BYD Seal 07 DM-i & Song Pro, OE 12798657-00

This valve fits a wide spread of BYD models, so the model name on its own is not enough to go on. Open the fitment table on this page, find your own model and build year in it, then check OE 12798657-00 against the marking on the valve you are replacing. Valvetrain references can change part way through a production run. If your car is not in the table, or your build year sits right at the edge of a range, use the quote route on this page and we will confirm the reference before you commit.

Not necessarily a problem. This item is listed under OE 12798657-00 and is also known as 472QA-1003102, so a different string on the old component does not by itself mean a different part. Compare what you have against both of those references before deciding. Do not judge it by the shape of the valve, because similar profiles are used across an engine family. If neither reference matches what is marked on yours, send us the marking with your model and build year through the quote route and we will check it against the catalogue.

The delivery time is 8 to 25 days, from order to door. If the car is off the road and a date matters to you, tell us before you order so we can confirm the current position on OE 12798657-00. The shipping cost for your country is shown on this page and confirmed at checkout before you pay. Before you order, check the number on your old part against OE 12798657-00.

The material given for this valve is metal, with no coating or composite element noted. In practice that means you are handling a bare engine component. It is supplied new and needs to stay clean and dry until it goes in, since grit on a valve stem does damage that no amount of care afterwards undoes. Nothing about the material calls for preparation before fitting. If your workshop wants a specific alloy or hardness figure, ask us through the quote route, because none is given here.

This valve sits in the engine bay. An exhaust valve of this kind sits within the valvetrain, which puts it inside the engine rather than anywhere you can reach from underneath the car. Access means the cylinder head has to come apart, so the labour around it is worth pricing before the part is on order. We do not publish fitting steps and none come with the part. Confirm your model in the fitment table on this page first, then let your workshop tell you what else is worth renewing while the head is open.

This one is listed in the Original/Genuine tier only, made by BYD. No Aftermarket alternative exists for OE 12798657-00 at present, so there is no second option to set beside it. That reflects what we can source for the reference rather than any view about the part itself. Where a second source does exist, both tiers are priced on this page and the choice is yours. Here there is a single version at the price shown on this page. If you want us to look for an alternative reference, use the quote route with your model and build year.
