Specs At A Glance

Good To Know

Q: How do I know my solenoid needs replacing? A: A single loud click with no crank, or intermittent starting that worsens over time, usually points to a solenoid that has failed. Testing for voltage at the starter terminal while cranking helps confirm the diagnosis.

Q: Does this solenoid bolt straight in? A: It is cross-referenced to 278003012 and mounts at the factory location with the original wiring connections. Confirm your model and serial number match before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
