Coolant Pipe Assembly for BYD Sealion 05 EV, OE 15646179-00

Because the routing of a coolant pipe is drawn for one car. This pipe is made for the BYD Sealion 05 EV alone, although several vehicle versions of that model share the same pipe. The bends are what limit it: a pipe formed for one engine bay layout will not follow another. If your car is a different BYD, work from your own OE number rather than from the shape of the part. Compare what is on your pipe with 15646179-00, and use the fitment table on this page to confirm the version.

Then it is the same part. UNEC-1303100 appears on this part as an alternative to the OE number 15646179-00, so either string identifies it. Which one appears on a given pipe depends on who marked it, and neither is more correct than the other. If your pipe carries something different again, do not assume it is a variation on the same thing. Send us the number exactly as it reads, including any suffix, and we will check whether it maps here or to one of the other coolant runs on the car.

Allow 8 to 28 days for delivery, counted from your order to your door. If you are booking workshop time around the part, confirm the current position with us first, quoting OE 15646179-00, so the car is not on a ramp waiting. The shipping cost for your country is shown on this page and confirmed at checkout before you pay. Before you order, check the number on your old part against OE 15646179-00.

Solid. It is made of metal, so it is a formed line that keeps its own shape and follows a fixed route through the engine bay. Fitting it is a matter of getting the ends onto their connections and the body of the pipe back into its brackets, in the reverse of the order the old one came out. Note the clip positions before you remove anything. If the replacement fights the route, check on the fitment table on this page that you have the correct pipe for your version of the car.

In the engine bay of the BYD Sealion 05 EV. That is where this pipe sits, and it is grouped on the cooling side of the range as Coolant Pipe 1. Other pipes on the same car sit in the same compartment, so position by itself will not single yours out. Use the numbers instead. The OE number is 15646179-00 and the alternative reference is UNEC-1303100. If the pipe you are replacing carries no legible marking, photograph its route before removal and we can compare that with what you send us.

No Aftermarket equivalent exists for it. Where a part has one, both tiers appear on the page together and are priced there, and buyers pick whichever suits the job. This pipe is available in the Original/Genuine tier only, so what you see is the BYD part. That is a fact about the current range rather than a restriction on ordering. The delivery time is 8 to 28 days, from order to door.
