BYD Seal electric sedan
BYD Seal Coolant Reservoir Wholesale
Coolant Reservoir selection for the original Seal electric sedan: tank location, hose branches, cap specification and level sensing.

Coolant Reservoir: application and selection
| Check | Required record |
|---|---|
| Assembly identification | Tank location, hose branches, cap specification and level sensing |
| Vehicle identity | Original Seal electric sedan; production date, original market, RWD/AWD and installed equipment. Other Seal and Sealion nameplates are separate applications. |
| Component comparison | Overall, label, mounting and connection views; measured dimensions where they distinguish the assembly. |
Several translucent vessels can look alike. Confirm the coolant circuit and do not substitute a washer bottle or infer cap pressure from colour.
Connected assembly checks
Map the coolant route before comparing the motor cooling radiator, electric coolant pump, coolant reservoir and coolant control valve. Each assembly needs its own port and installed-location record.
Keep these decisions with the BYD Seal Cooling & Cabin Climate Parts Guide. If vehicle details conflict, use Seal model and drive identification before comparing references.
