Frequently Asked Questions: OE 13643550-00
You have selected Aftermarket, the aftermarket alternative to this part. Where an answer below names BYD as the maker or calls the part Original/Genuine, it describes the Original/Genuine version, not this one.
What is the difference between Original/Genuine and Aftermarket for this cross member?
Original/Genuine means the part comes from BYD and matches the car exactly. Aftermarket is made to the same fitment but not by the vehicle maker. Before deciding, look at the number stamped on the part you are removing, since that confirms which one you actually need rather than which one seems the safer choice. If the two tiers are not both shown for this listing, the one on this page is the one available to order.
What if the number on my old cross member does not match 13643550-00?
A different number usually means a different side, position or fixing arrangement, not a faulty listing. This cross member sits in the engine bay, so check which side yours is fitted to, how it lines up, and whether the fixings on your car match what you can see before ordering. If anything looks uncertain once you compare it against your own vehicle, do not fit this one on the strength of the name alone.
How does a part this size actually turn up at my door?
Delivery time is confirmed with your quote. The packaging details are shown on this page. Match the OE number 13643550-00, or the alternative EQEA-5301940, against the old cross member while it is out of the car, so you know it is the right one before delivery is even booked. Checking the number before you order is what makes sure the cross member that arrives at your door is the correct one for your BYD Seagull, rather than one that only looks similar.
What is this cross member made of and is that the right build for the engine bay?
It is metal, finished in black, and is a solid structural piece rather than a light trim panel. The photographs on this page show the shape and the mounting points before you commit, which is worth checking against the old part in your hand. If the profile does not match what you are holding, do not fit it, check the fitment table on this page instead.
Will this cross member need painting to match the car?
It is supplied in black and there is no finish option listed beyond that. If your car needs an exact colour match, the metal will take paint before fitting. This is a structural part fitted within the engine bay, so any painting is about appearance, not function, and can be done once it is on the car. If you are not sure whether this one suits your Seagull, use the quote route on this page and confirm against your old part's OE number first.
Where does the engine bay lower cross member fit on my BYD Seagull?
This is a structural piece in the engine bay, matched to OE 13643550-00, also listed as EQEA-5301940. Before ordering, check the model and model year shown on your registration document, since that confirms you are ordering the correct one for your car. Delivery time is confirmed with your quote.
