Coolant Pipe for BYD Destroyer 05 & Qin PLUS DM-i, OE 12978612-00

Go by what is stamped on the pipe you are removing rather than this listing alone. This one is listed under OE 12978612-00, also shown as HA2HE-1303220, for the BYD Destroyer 05 and Qin PLUS DM-i. If the marking on the old part reads differently, the safest step is to look for that exact number, since a mismatch usually means a different version exists. Keep the old pipe to hand when you check, as reading it directly is more reliable than working from memory.

Delivery takes 8 to 25 days from your order to your door. Use that waiting time to look at the side, the position and the fixings the old pipe uses in your engine bay, rather than working it out once the new one lands. Knowing exactly how it sits and connects on your own car now means fitting will go smoothly when the part arrives, with nothing left to puzzle over at the last minute.

This is a metal pipe, not a rubber hose. It comes as a fixed shape rather than something you can flex into place, so it needs to match the routing of the original exactly. Check the OE number on your old pipe, 12978612-00, or the alternative reference HA2HE-1303220, against what you are removing before ordering. If you are not certain it lines up with your car, use the quote route on this page and someone will confirm fitment for you before you buy.

The engine bay is where this pipe is fitted, as part of the cooling system pipework rather than anywhere further back under the car. To see exactly where it sits and how it connects, look at the photographs on this page before you order, comparing them against the pipe you are currently removing. Matching the photograph to what you can see under your own bonnet is a more reliable check than working from the description alone, especially if you are not completely sure of its position.

Only the original version of this pipe is listed here, made by BYD. That reflects what is currently listed, not a claim that no aftermarket version exists, so if you would rather have one priced, keep the old part in front of you and ask us to look into it before you order. Having it to hand means whatever we find can be checked against the real thing, rather than against a description alone.
