About This Part
This coolant pipe assembly suits the BYD 2nd-Gen Yuan PLUS Smart Driving (2024-2026) and carries OE 15645040-00 with factory reference SC2EV-1303200. The reinforced rubber hose routes coolant through the thermal-management circuit, and its moulded bends and lock clips hold the run clear of surrounding hardware. The braided sleeve and printed flow arrows follow the original layout for a direct fit. Renew this cooling water pipe if you find cracking, bulging or a coolant weep at either connector.

Frequently Asked Questions: OE 15645040-00
Will this fit any BYD Yuan PLUS or only one version?
This coolant pipe assembly fits the BYD 2nd-Gen Yuan PLUS only, and the OE number 15645040-00 is not shown against any other model. If your car looks close but you are not certain which generation you have, do not guess from memory. Look at the photographs on this page and match the pipe shape, the connector positions and the bend of the moulding against the part currently fitted in your engine bay before you order, since a plastic moulding only mates with the fixings it was designed for.
What if the number on my old part is different?
If the OE number on the old pipe does not match 15645040-00, do not fit this one. Look at where it sits in the engine bay, which side it runs to, and how it is fixed in place, then match that against what is shown on this page before you order. Getting this wrong on a moulded assembly like this means it will not seat properly, since it cannot be trimmed or bent to fit like a length of hose. If anything looks uncertain, use the quote route on this page rather than guessing.
What is this coolant pipe made of?
Yes, this pipe is made of black plastic and supplied new, not reconditioned. It is fitted in the engine bay of the second-generation Yuan PLUS. If your own parts list or catalogue does not carry BYD's OE number, this pipe is also listed under the code SC2EV-1303200, so search that reference as well as 15645040-00 to find the right match before you order.
Where does this coolant pipe fit on the Yuan PLUS?
It sits in the engine bay as part of the cooling system, listed under OE number 15645040-00 for the BYD 2nd-Gen Yuan PLUS. Because it is a moulded plastic assembly rather than a length of hose, it needs to be matched to the exact model and year on your registration document before you order, so the shape and connections line up correctly. If you are at all unsure which one your car needs, use the quote route on this page rather than guessing from the old part alone.
