Frequently Asked Questions: OE 14257837-00
How do I know this coolant pipe will fit my BYD Seal 06 DM-i?
Match this against the number stamped on the pipe you are removing, OE 14257837-00. That stamped figure is what confirms the part in your hand is the same as the one listed here, not the model or trim on your logbook. Take the old pipe out, find the marking on the moulded plastic body, and compare it directly before you order. If the numbers agree, this is the correct assembly for your car.
What if the number on my old pipe does not match 14257837-00?
Do not order on a hunch. This listing also appears under HKHA-1303120, so check that reference too before ruling it out. If neither number matches what is stamped on your old pipe, look through the photographs on this page against the shape, the bends and the connector ends of the part you are removing. A pipe that looks similar is not the same as one that is confirmed.
What is this coolant pipe made of?
This one is plastic, moulded in black. It is listed as a single assembly rather than a length of hose, built to sit in the engine bay on the BYD Seal 06 DM-i. Have the old part in front of you before you order, and check the OE number stamped or printed on it against 14257837-00 given here. If the numbers do not match, this is not the right one, whatever the pipe looks like from a distance.
Where does this coolant pipe fit on the car?
It sits in the engine bay, one part of the cooling system routing coolant between components. Before you fit it, look at the side, the position and the fixings on the pipe you are taking off, and match those to this assembly. The OE number is 14257837-00, so check that against the marking on your old pipe if you can still read it. Getting the position and fixings right first means the new pipe lines up on refit without forcing anything into place.
