BYD Song Plus Radiator

About this part: Radiator

The radiator transfers heat from engine coolant to passing air. Most modern units use an aluminium tube-and-fin core with moulded plastic end tanks crimped on over a gasket. Vehicles with automatic transmissions often have a transmission oil cooler built into one tank, and hybrids and battery-electric vehicles carry additional low-temperature circuits for power electronics and battery conditioning.

Symptoms that usually point to it on a vehicle like the BYD Song Plus:

• Coolant loss with no visible external leak, or a sweet smell and white crusty residue along the end-tank seam.
• Temperature climbing in traffic but settling on the move, which points to airflow or fan problems as much as to the radiator itself.
• The cabin heater blowing cold at idle — a classic low-coolant symptom.

Ordering this part

Give core width, height and thickness, the position and diameter of the inlet and outlet necks, whether there is an integral transmission oil cooler, and whether the vehicle is manual or automatic and has air conditioning. All four change the part number.

Fitment is confirmed from the VIN and from the number on the part being replaced, not from the model name alone: engine variant, trim, market specification and mid-life revisions all change part numbers within the same model year. Send the VIN, the model year, the transmission type, whether the vehicle is left- or right-hand drive, and a photograph of the old part showing any number printed on it.
