About This Part
Coolant pipe assembly (OE 15645086-00, cross-reference SC2EV-1303210) that carries coolant between the cooling-circuit components. The formed pipe runs with moulded quick-connect fittings and support clips and fits the 2nd-Gen Yuan PLUS Smart Driving 2024-2026. Its pre-bent shape and locating clips route it cleanly through the bay and seal at each connector. A split or leaking coolant hose drops system pressure and risks overheating, so this ready-to-fit replacement pipe, also called a coolant line or water hose, restores a sealed circuit.

Frequently Asked Questions: OE 15645086-00
Does this pipe suit more than one BYD?
No. Only one model is given for it, the BYD Yuan PLUS. An underbody coolant run is routed around the floor of that particular car, so the fixing points and the overall length are specific to it. A pipe from a related car can look similar and still be wrong by a few cm at the ends. If your vehicle is not the one named, do not order on resemblance. Compare the OE number 15645086-00 with what is on your own pipe, then use the fitment table on this page.
The reference on my old pipe does not match. What now?
This pipe has two references. The OE number is 15645086-00, and SC2EV-1303210 also applies to the same item. Parts made to one drawing are often marked under more than one scheme, so the string you can read may be either of them. Either match confirms the listing. If the marking has been scoured off by road grit, which happens readily on a run under the car, tell us whatever characters are still legible and we will trace it instead of guessing.
What is the timescale on this pipe?
Delivery time is confirmed with your quote. Only one of those applies at any moment and the page shows you which. Delivery on top of that comes down to the carrier service chosen at checkout. Quote the OE number 15645086-00 if you want the position confirmed before ordering, and we will check the current state of this listing.
This pipe is well over a metre. How does it ship?
As a long parcel. It is longer than most carriers treat as standard, so it travels as an oversized item rather than in a standard box. The packaging details are shown on this page. Check that the delivery address can receive something of that size, and that there is somewhere it can be left safely if you are out during the day. Let us know in advance if the access is tight.
What is this pipe made from?
Metal. It is a rigid formed line rather than a flexible hose, so it goes back exactly the way it came out and relies on its brackets to stay put. Working underneath the car, that means freeing the mountings before you try to move it rather than the other way round. If you are unsure which of the coolant runs on this car you have in front of you, the fitment table on this page lists them separately.
Where does this pipe sit on the car?
Underneath. It is catalogued as Coolant Pipe 12. You will need the car raised and properly supported to see it, and you will be working around road dirt on the fixings. Identify the one you want by number before you start: the OE number is 15645086-00 and the alternative reference is SC2EV-1303210. The fitment table on this page confirms the model.
Why only the genuine version here?
Because that is all that is shown for this pipe. Our listings show an Original/Genuine tier and, where one exists, an Aftermarket tier beside it, priced on the same page. No Aftermarket equivalent is shown for this pipe, so there is a single option and a single price on this page. If you were expecting a choice, that is the reason for its absence. Anything added to the range later would appear here under the same OE number 15645086-00, so the listing you have open stays the right one to watch.
