About This Part
Drive-motor radiator assembly for the BYD Seagull, spanning the newest Seagull Smart Driving (2025-2026) back through the Seagull Glory and 2025 Seagull (2023-2025). Listed as OE 13705085-00 with reference EQEA-1301030, this aluminium coolant radiator carries the fin-and-tube core with moulded plastic tanks and the upper and lower hose necks. Mounted at the front of the engine bay, it sheds heat from the electric drive system to hold coolant temperature under load. Clogged fins or a weeping core raise running temperatures, so a clean, leak-free motor radiator keeps the cooling circuit working as intended.

Frequently Asked Questions: OE 13705085-00
You have selected Aftermarket, the aftermarket alternative to this part. Where an answer below names BYD as the maker or calls the part Original/Genuine, it describes the Original/Genuine version, not this one.
Whats the difference between original and aftermarket for this radiator?
Original is the BYD-made assembly, built to the same spec as the one currently fitted. Aftermarket is a replacement built to match form and function without carrying the maker name. Both are listed as new. If you are not sure which suits your car or your budget, use the quote route on this page and ask directly, since the right choice depends on how the car is used and what you plan to spend.
What if the number on my old radiator is not 13705085-00?
Do not fit this one on the strength of the description alone. Radiators carry an OE number for a reason, and a close-looking part with a different number can still be wrong for your car. This one is also listed as EQEA-1301030, so check both against what is stamped or printed on your old unit. Then open the fitment table on this page to confirm your exact model is listed before you order.
What is the Motor Radiator I made of?
This is a metal radiator assembly. Before you order it, find the OE number stamped on the radiator you are taking off and check it against 13705085-00, or the alternative reference EQEA-1301030, so you know the replacement matches what is actually fitted to the car.
Where does this radiator fit on the Seagull?
It fits in the engine bay, and the photographs on this page show its position and shape so you can compare it against what is currently fitted before you order. Check the OE number on the old radiator, 13705085-00, against the one listed here to confirm it is the right part. This is a new metal radiator assembly, listed under BYD and also as EQEA-1301030. If the numbers do not match, hold off ordering and check the fitment table on this page instead.
