About This Part
Evaporator case assembly for the BYD Seal 05 DM-i Smart Driving (2024-2026) and 2nd-Gen Qin PLUS DM-i Smart Driving (2024-2025), matching OE 16861449-00 and supplier number HA6HA-8100100.

Frequently Asked Questions: OE 16861449-00
What if the number on my old part is different from this one?
Check that number before you order, because 16861449-00 must match what is on the case you are removing. BYD also lists this as HA6HA-8100100, so either reference confirms a match. If the figures on your old case are different, do not assume it is close enough. Look at the fitment table on this page, where the correct references for your car are set out, and compare them against what is stamped on the part in your hand before you commit to the order.
What is this evaporator case made of?
This case is made of plastic, not metal. Weight is shown on this page. It comes new rather than used, so check its shape carefully against the case you are removing before fitting. Have a look at the photographs on this page before you order, so you can compare the shape, the ducting and the mounting points with the part currently fitted.
Where on the car does this evaporator case sit?
Inside the car, not under the bonnet, is where this case belongs, forming part of the evaporator, blower and heater core assembly within the HVAC and climate system. Because it sits inside the cabin structure, it is not something you can identify by sight from outside, so getting the reference right matters more than usual. Find the number stamped on the part you are removing and check it against 16861449-00 or the alternative reference HA6HA-8100100 before buying this case.
