Solenoid Replacement for Mitsubishi Starters
Be sure to follow proper safety techniques as outlined by your shop or employer. This includes wearing safety glasses and gloves at all times, and disconnecting the vehicle’s batteries during any repair of the starting system.
The components listed below may continue to have power supplied to them even when the ignition switch is off. Use extreme caution at all times.
Solenoid Removal Instructions:
- Remove the starter from the vehicle: Remove the vehicle’s battery, ground, and switch cables from the starter. Remove three starter mounting bolts. Get the starter installation guide from Guides & Downloads for complete removal instructions.
- Remove nuts from solenoid’s M terminal, and starter’s ground terminal. These terminals are shown in the Starter Diagram below. Disconnect cables connecting solenoid to the motor.
- Remove three solenoid screws connecting solenoid to starter’s drive housing. This step is most easily performed using an impact driver as shown in Figure 2.
- Remove solenoid from starter by pulling back and lifting upward. The solenoid is most easily removed with the pinion extended.
Solenoid Replacement Instructions
- Align the rubber packing’s mounting holes with mounting holes on solenoid.
- Re-connect solenoid’s plunger with starter’s shift lever as shown in Figure 3. This is most easily done with the pinion extended. The solenoid M terminal’s threaded post is shorter than the B terminal’s threaded post. The M terminal should be closest to the motor.
- Push solenoid towards pinion end of starter while tightening 3 solenoid securing screws provided with replacement kit. Do not re-use old screws, as new screws are coated with fresh thread locking compound. Ensure rubber packing is seated properly between solenoid and front bracket.
- Re-connect wires as shown in the Starter Diagram below.
- Torque all connections to values shown in the Table below.
| Solenoid Screw | B | M | Ground | SW | Mounting Bolts | |
| lb.ft | 3.6-6.5 | 15-22 | 15-22 | 15-22 | 1.5-1.8 | 74-174 |
| lb.ft | 43-78 | 180-264 | 180-264 | 180-264 | 18-22 | |
| N.m | 4.9-8.8 | 20-30 | 20-30 | 20-30 | 2.0-2.5 | 100-200 |
| Size | M12 | M12 | M12 | M5 |
