About This Part
Left front coolant pipe assembly for the BYD Seal 05 DM-i (2025-2026) and 2026 Qin PLUS DM-i, with further BYD DM-i and Qin PLUS EV fitments, OE 12185251-00 (reference HAD-5703710).

Frequently Asked Questions: OE 12185251-00
Which side of the engine bay does this coolant pipe serve?
The left front position, read as you sit in the car facing forward. A coolant pipe is shaped to its own side of the bay, so the left assembly will not sit correctly on the right and the bends will fight you if you try. Before ordering, look at the routing of the pipe you are taking off and compare it with the images on this page. If your car has more than one pipe in that area, use the OE number 12185251-00 stamped or labelled on the old assembly to settle which one you are replacing.
This pipe is listed for several models. How do I confirm mine?
Work from the fitment table on this page rather than from the model name in the title. The listing spans a good many models and a far larger number of individual vehicle versions, and cooling layouts can change within one model over its life. Find your own build year and variant in the table first. If the entry is there, match the OE number on the pipe you are removing as a second check. If your version is absent, or the table is ambiguous for your car, send a photograph of the old part and its label through the quote route and we will confirm against the OE number.
My old pipe carries a different reference. Is that a problem?
Probably not. Labels on cooling parts often sit on a sleeve or a collar near one end, and they can be obscured by residue, so clean the area before deciding what it says. If the reference you read is neither of ours, do not order in hope. Send it on the quote route with your build year and we will check whether this pipe is the right one for your car.
When can I expect this pipe to arrive?
The delivery time is 8 to 28 days, from order to door. The assembly travels as a flat parcel, and its packaging details are on this page. A cooling job will have the car off the road, so book the workshop against the far end of the delivery time rather than the near end. The shipping cost for your country is shown on this page and confirmed at checkout before you pay.
Is this a metal pipe or a rubber hose?
Metal is what this assembly is made from, so you are buying a formed pipe rather than a flexible hose. That has a practical consequence when it arrives. A formed pipe holds its shape, which means it either lines up with your mounting points or it does not, and the images on this page are worth studying closely before you order. The packaging details for the boxed item are shown on this page. Check that the end fittings on the picture match the ones on your car.
Is an aftermarket coolant pipe available for this car?
None is available for this OE number. What we offer is the Original/Genuine assembly from BYD, with no Aftermarket manufacturer or second price for it. Where a part does exist in both forms, the two tiers appear priced on this page so you can choose. Here there is a single version. Formed coolant pipes are model specific by shape, which is often why a second source is not available. If you want us to look anyway, quote 12185251-00 and your build year on the quote route.
