Switch your starter circuit on cleanly with the Standard Ignition Starter Solenoid SS-493. It drops in as a direct-fit replacement for the 1998-2001 Nissan Altima (L4-2.4L). A starter solenoid is the electromagnetic switch that, when energized by the ignition switch, closes the high-current circuit from the battery to the starter motor so the engine can crank.
- Low voltage drop: polyester-insulated magnet wire, cadmium-plated copper discs, and solid contact bolts help deliver full battery power to the starter while guarding against electrical overload.
- Heavy-duty copper contacts: reduce the effect of arcing to help extend solenoid life.
- More pure copper windings than found on most vehicles, for a stronger magnetic field.
- Pure copper battery terminal studs: reduce resistance for higher current flow, even in hot environments.
Rated 12 volts with three male stud-and-blade terminals and one female connector; lug hole 0.18 in (4.572 mm). Continuous duty: No. Mounting hardware, mounting brackets, and a return spring are not included, and there are no mounting holes; consult the vehicle service information for the correct fasteners. Finish: black/gold with a dichromate and plastic finish. Country of origin: Japan. If a failed starter solenoid is the cause of a no-crank or single-click condition, this replaces it.

Frequently Asked Questions
What does this starter solenoid do?
It's a 12-volt electromagnetic switch that engages the starter and closes the high-current circuit from the battery to the starter motor when the ignition is turned.
Which vehicle does the SS-493 fit?
It's a direct-fit replacement for the 1998-2001 Nissan Altima with the L4-2.4L engine. Check the Buyer's Guide tab to confirm it matches your vehicle.
Does it include mounting hardware or a spring?
No. Mounting hardware, mounting brackets, and a return spring are not included, and it has no mounting holes. Consult the vehicle service information for the correct fasteners.
What are signs this solenoid may need replacing?
A single click with no crank, an intermittent no-start, or the starter failing to engage. Diagnose the cause first, since other parts can produce these symptoms.
What are its terminals and where is it made?
It has three male stud-and-blade terminals and one female connector, is rated 12 volts, and its country of origin is Japan.
