Heater Coolant Return Hose for BYD Song Pro DM-i & more, OE 12849639-00

Work from the fitment table on this page rather than from the model name in the title. This hose covers a broad spread of BYD models and versions, and a heater hose can change between one build and the next even where the badge on the boot is the same. Find your model, then your version, then your build period in that table. After that, check the number on the hose you removed against 12849639-00 or 472QA-1306011. If your version is not shown, use the quote route on this page.

No. Either marking points at the item on this page. Read what is printed along the hose body carefully, because one digit misread on a wet or dirty part sends you to the wrong listing. Where the number you have matches neither, do not order on the strength of the shape looking right. Send the marking and your vehicle details through the quote route on this page and let us check it.

The delivery time is 8 to 25 days, from order to door. That is how long we take to pick it and pass it to the carrier. If the heater circuit is opened up and the car is waiting on you, the sensible plan is to have the hose in hand before the coolant comes out rather than the other way round.

The material is Rubber, the colour is Black and the condition is New. That is everything we offer on how it is built. Use it as a matching check rather than as a specification. What comes off the car should be a black rubber hose following the same run, and if yours is a moulded plastic pipe, you have a different part in front of you.

It is an engine bay item, listed as the Heater Coolant Return Hose, so it belongs to the return side of the heater circuit. Before ordering, follow the heater pipes at the bulkhead and identify which of them you are actually replacing, since a feed and a return sit close together and look much alike. The fitment table on this page will confirm the hose against your model and version, and the alternative reference 472QA-1306011 gives you something else to look for on the part you removed.

The genuine manufacturer is BYD, and there is no Aftermarket manufacturer against it, so the page carries one part rather than two tiers. Where both exist, you would see the choice on the product page itself. Here you do not. If you would rather we hunted for an alternative to 12849639-00 or 472QA-1306011, the quote route on this page is the way to ask, and your vehicle details will make the answer quicker.
