Frequently Asked Questions: OE 14028665-00
What if the number on my old pipe does not match 14028665-00?
Go by what is stamped or cast into the old pipe rather than what you expect it to be. If that number differs from 14028665-00, this is not the right pipe for your car and fitting it risks a leak at the connectors. It is also listed as UXEC-1303120, so check against both before ruling it out. If neither matches, hold off ordering and use the fitment table on this page to find the correct pipe for your vehicle.
What is this coolant pipe made of and does that matter for fitting it?
It is plastic, moulded to shape rather than a length of flexible hose, so it cannot be shortened, bent or joined to fit if it is slightly off. It has to match the original at every mounting point and connection. Quote the OE number 14028665-00 when you order and compare it against the marking on the old pipe before you fit the new one, so the shape and the fixings line up first time.
Where does this coolant pipe actually go on my BYD?
This is fitted in the engine bay as part of the cooling system, carrying coolant between the points it connects to under the bonnet rather than sitting elsewhere on the car. It is listed as new, made in China to the OE number given, so it is a complete replacement piece rather than a repaired one. If you are not certain this is the exact pipe your engine bay needs, use the quote route on this page and give the details so it can be checked before you commit to an order.
