Frequently Asked Questions: OE 15645042-00
Why is this only listed for one model?
This part is shown here only for the Yuan PLUS. Before ordering, look at which side of the engine bay your old pipe runs, where its fixings sit, and how it is moulded, since a shaped plastic assembly like this cannot be adapted to fit another layout. Match the side, the position and the fixings on your own car to this part first. If they line up, you have the right one. If they do not, a similar looking model is not enough to go on, so check your own car rather than the old part alone.
What if the number on my old part is different?
This part is matched to OE number 15645042-00, so a different number on your old part means it may not be the same pipe. Do not fit it on the assumption that a close match will do. Use the quote route on this page and give the number from your old part, along with your model and model year, so it can be checked before you order. It is also listed under reference SC2EV-1303180, worth mentioning if that appears on your paperwork instead.
What is this pipe made of?
Black plastic, moulded as one full assembly, is what this pipe is made from, not a length you can trim or bend into shape. That means it fits one way only, matching the exact route and fixings of the part it replaces, with no room to adjust around a slightly different layout. Because of this, it is worth confirming the fit before you buy rather than after. Check the fitment table on this page against your own model, since a moulded plastic assembly needs to match precisely from the start.
How do I know this coolant pipe is right for my Yuan PLUS?
This assembly carries OE number 15645042-00, so match that against the number on the pipe you are removing rather than guessing from the model name alone. It is a moulded plastic assembly fitted in the engine bay, not a length of hose, so it cannot be shortened or reshaped to fit if the old part looks slightly different. If the numbers do not line up, use the quote route on this page before ordering so the right part reaches you first time.
