Specs At A Glance

Good To Know

Q: How do I know my solenoid needs replacing? A: A single loud click with no engine crank, or intermittent starting that worsens over time, usually points to worn solenoid contacts. Testing for voltage at the starter terminal while cranking confirms whether the solenoid is passing current.

Q: Is this a plug-and-play replacement? A: It matches the OEM 278003012 terminal arrangement, so it mounts and connects the same way as the original unit. Always disconnect the battery before swapping the solenoid to protect the electrical system.

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