Frequently Asked Questions: OE 14252121-00
How do I know this coolant pipe will fit my car?
Check the fitment table on this page against the side, the position and the fixings on your own car before ordering. This assembly is listed under OE number 14252121-00 for the BYD Seal 06 and Seal 05 DM-i, so matching that number against the pipe you are removing is the surest way to confirm it. If your old part carries a different OE number, hold off and use the quote route on this page instead.
The number on my old pipe does not match 14252121-00, what now?
Do not fit it on the strength of the number alone. Take the model and the model year exactly as shown on your registration document and check them against the fitment table on this page before you order. This assembly is moulded to fit a specific application, so getting the model year right matters more than matching numbers by eye. If the details on your document line up with the table, you can order with confidence.
What is this coolant pipe made of?
It is a rubber pipe, moulded as a complete assembly rather than a plain length of hose you would cut and clamp yourself. That means it goes in as one piece, with its shape and connections already formed, not built up from separate sections on the bench. It is black and carries OE number 14252121-00, listed for the BYD Seal 06 and Seal 05 DM-i. Have a look at the photographs on this page to see the exact shape and connection points, and check the OE number against your old pipe before you order.
Where does this pipe fit on the car?
The engine bay is where this pipe assembly sits, as part of the cooling system rather than anywhere near the cabin or the boot. Only one version of this pipe is listed here, for the BYD Seal 06 and Seal 05 DM-i, so if you are at all unsure whether your car uses this exact pipe in that position, use the quote route on this page rather than guessing from the description alone. Delivery takes 8 to 25 days from your order to your door.
