About This Part
Coolant pipe assembly for the BYD Destroyer 05 Glory (2022-2025), Destroyer 05 (2022-2025) and Qin PLUS DM-i Glory / DM-i (2020-2025), supplied under OE 12978602-00 and BYD reference HA2HE-1303170. It is a long, formed steel coolant tube run with the bends, brackets and connector stubs set to the factory routing, so the cooling pipe drops back into place without reshaping. Use it to replace a corroded or leaking original coolant line in the engine bay. Fit new O-rings at each joint on assembly.

Frequently Asked Questions: OE 12978602-00
The pipe I took off carries another code. Is this the right listing?
On coolant pipes the marking is often on a moulded tag or printed along the tube, and coolant staining can make it hard to read. Clean it and look again. If neither reference is there, send what you can read on the quote route on this page and we will check it against the fitment table. Keep the old coolant pipe 8 until the new one is fitted, in case the two need comparing.
How soon can this pipe be with me?
Delivery time is confirmed with your quote. Cooling repairs often need more than one pipe from the same family, so if you are ordering others from this page, ask on the quote route whether they can be brought together in one movement. The shipping cost is confirmed with your quote. Before you order, check the number on your old part against OE 12978602-00.
How does a pipe this long get delivered?
The packaging details for this assembly are shown on this page. Make sure the delivery address can take the carton and that somebody is there to receive it, since a long box is not one to leave outside. If access is tight, mention it on the quote route on this page first. Check the OE number against the old pipe before you fit the new one, so you know everything lines up.
What is this pipe made of?
It is made from metal, so this run is a rigid tube rather than a flexible hose. That matters when you handle it. A rigid pipe that is bent out of shape will not sit back on its mounting points, so keep it straight in transit and while you carry it to the car. It is supplied in new condition and finished in black. Check the end fittings in the photographs on this page against the pipe you are removing before you order.
Where does this pipe run?
It sits in the engine bay. No left or right side applies to it, so there is no handed version to choose between here. Nothing traces the route the pipe takes on your model line or names the components at each end, and we will not invent that. What you can do is compare the bends and the fittings in the photographs with the pipe on the car, then confirm your model line and build year in the fitment table on this page.
Why is a single version listed for this pipe?
Only the Original/Genuine line built for BYD is available for this reference, with no independent equivalent beside it. Shaped coolant pipes are made to one car's layout, so a second supplier has to copy the bends exactly before an alternative can be worth listing. Where nobody on our books does that, we list one line rather than something approximate. If you have been offered a different reference for the same run, send it through the quote route on this page and we will look at it.
