A/C Expansion Valve for BYD Seal 05 DM-i, OE 16465416-00
Price shown without any local sales tax. Shipping is shown on this page and confirmed at checkout. Import taxes and duty in Hong Kong SAR are not included and may be charged when the parcel arrives.
About This Part
The A/C expansion valve meters high-pressure liquid refrigerant into the evaporator, dropping its pressure so it can absorb cabin heat on the BYD Seal 05 DM-i (2025-2026), Qin PLUS DM-i (2025-2026) and Qin L DM-i Smart Driving from 2024, among other BYD models. This aluminium thermal expansion valve, OE 16465416-00 (reference HA3HA-8106100), regulates flow to keep vent temperatures steady as load changes. Weak cooling, frost on the lines or erratic vent temperature often trace back to a sticking TXV. Renew it whenever the air conditioning system is opened for service.

Frequently Asked Questions: OE 16465416-00
How do I know this expansion valve will fit my BYD Seal 05 DM-i?
Match it by the number stamped on the part you are removing rather than by model or trim, since that stamped number is what confirms it against the fitment table on this page. Take the old valve out, find the marking on its body, and compare it there before you commit to the order. This is a metal component fitted in the engine bay, so the marking should be legible once it is clear of the pipework. If you cannot find a clear number, send a photograph of the old part and its label through the quote route on this page instead.
What if the number on my old valve is not 16465416-00?
That happens more often than you would think on this part. Rather than guessing which listing is right, use the quote route on this page and give the details of the number you have found. Someone can then match it against known equivalents, including HA3HA-8106100, and confirm whether it is the same valve under a different reference before you spend anything.
What is this valve made of and does that affect fit?
This valve is made of metal, so it is a solid mechanical part rather than a flexible line, and it must match the exact mounting and pipe connections on the car rather than being adapted to fit. Fitment is model specific, so check the fitment table on this page to confirm it matches your BYD Seal 05 DM-i before ordering, and compare the OE number 16465416-00 against the number on your old part.
Where does the expansion valve sit on my Seal 05 DM-i?
It sits in the engine bay, in the air conditioning circuit, carrying the OE number 16465416-00. Before you order, find the model and model year exactly as printed on your registration document, since this is what confirms you are looking at the right build of the car. With that in hand, check it against the fitment table on this page. The valve is new and made of metal, and only this one listing is shown for the part.
