Frequently Asked Questions: OE 12978632-00
What if the OE number on my old part is different from this one?
If the OE number stamped on your old pipe does not match 12978632-00, do not fit this part on the strength of a visual match alone. This assembly is listed for the BYD Destroyer 05 and Qin PLUS DM-i, and the fitment table on this page sets out exactly which vehicles it suits. Compare your old part and its number against that table before you order. If your number is still not listed there, stop and check the table again rather than assuming this is the right pipe.
How long will this take to arrive?
Allow 8 to 25 days for delivery, counted from your order to your door. Keep that window in mind if you need the car back on the road by a set date. While you wait, you can also find this same pipe listed under the reference HA2HE-1303240, which is worth checking if you are cross referencing parts elsewhere or confirming you have the right item before it ships.
What is the coolant pipe made of?
This one is plastic, moulded in black, and listed under OE number 12978632-00. It sits in the engine bay so it faces heat and pressure from the cooling system rather than knocks or stone chips, and it arrives new rather than reconditioned. If you want a closer look at the shape and finish before ordering, the images on this page show the pipe itself so you can check it against the one on your car.
Where does this coolant pipe fit on the car?
This is the coolant pipe assembly fitted in the engine bay on the cooling system, listed for the BYD Destroyer 05 and Qin PLUS DM-i. Because it is a moulded plastic pipe rather than a length of hose, it has to be an exact match rather than a shape you can trim to fit. Before ordering, take your old pipe out and check the marking against OE number 12978632-00, or the alternative reference HA2HE-1303240, to be certain it is the same one.
Is there an aftermarket version of this coolant pipe?
Only the Original listing appears against OE number 12978632-00 on this page, with no aftermarket option shown alongside it. If you would rather compare prices before deciding, ask for an aftermarket equivalent to be found and quoted against this OE number through the quote route on this page, so you have a second figure to weigh against the price shown here.
