Q: What engine is this alternator intended for? A: The listed engine application is 2.4L L4.

Q: What are the listed voltage and amperage ratings? A: The listed electrical rating is 12V and 70A. Match these specifications to the original unit.

Q: What pulley and regulator configuration is listed? A: The product information lists a 1-groove pulley, internal regulator and internal fan.

Q: Can a weak alternator cause the battery warning light to appear? A: Yes. A charging-system fault can trigger a warning light, but the battery, wiring, belt drive and grounds should also be diagnosed.

Q: What should be checked before ordering? A: Confirm year, make, model, engine, amperage, connector, pulley, mounting points and OE/interchange number.

Q: Should the battery be disconnected before installation? A: Yes. Disconnect the negative battery terminal and follow the vehicle service procedure.

Q: Should the drive belt and tensioner be inspected during replacement? A: Yes. Inspect the belt, tensioner and pulley condition because wear or incorrect tension can affect alternator operation.

Q: What should be checked after installation? A: Verify belt routing, secure electrical connections and charging-system operation to the vehicle manufacturer's specification.

Q: Will replacing the alternator always solve a battery-drain or no-charge problem? A: No. A weak battery, damaged cables, poor grounds, belt-drive problems or parasitic draw can produce similar symptoms.

Q: Is this a genuine OEM alternator? A: No. This is a BDFHYK aftermarket replacement product. OE and interchange numbers are provided for fitment reference.
