Frequently Asked Questions: OE 13701987-00
How do I know this cross member will fit my Seal 05 DM-i?
Look underneath at the part you are removing and find the number stamped on it, then match that against the OE number 13701987-00 given here. Do not rely on the model or trim alone, as underbody structure parts like this can vary between build runs. If the stamped number matches, or matches the listed cross reference HA2HF-5101330/77, you can order with confidence. If you cannot find or read the number, take a clear photograph of the area and check it against both references before placing the order.
What if the number on my old part is different to this one?
If the number on your old part does not read 13701987-00, treat that as a mismatch rather than a close match. This part is listed under one OE number only, so a different code on your own component means it is not the right one for this car. Do not order on the strength of the model name or a memory of what the old part looked like. Have the old cross member in front of you, read the number stamped on it directly, and set it beside 13701987-00 before you commit to buying. A moment spent checking now saves a wrong part arriving later.
How will a rear floor cross member this size turn up?
The packaging details are shown on this page. Delivery time is confirmed with your quote. Confirm before ordering that this is the side and position your BYD Seal 05 DM-i needs, and note the fixings the cross member connects to underneath. Match the OE number, 13701987-00, against the marking on your old part so the one that arrives is the correct one for that spot.
What is this cross member made of?
Being metal, this cross member is a structural part rather than a trim piece, and it is supplied new. It is also listed under the reference HA2HF-5101330/77, alongside OE number 13701987-00, so if your paperwork or a supplier quote shows the other code, you are still looking at the same part. Check both references before you order, particularly if you are comparing this listing against another one, since they will not obviously match at a glance. Keep 13701987-00 and HA2HF-5101330/77 together in your notes so nothing gets lost between one document and the next.
Where does this cross member fit on the car?
This sits at the rear of the underbody, forming part of the lower floor structure that the frame and subframe attach to. It is listed under OE number 13701987-00, also referenced as HA2HF-5101330/77. Before ordering, match this OE number against the number on the part you are removing, and confirm the model and model year shown on your registration document. Delivery time is confirmed with your quote.
