Find a Part By:

Searching for your parts in the DENSO part catalog is easy. Simply select the type of part you are looking for along with the year/make/model of your vehicle.

    or

    Search for cross reference part numbers for other manufacturers of the parts you're looking for.

    Cross Reference information is provided as a guide only. Please refer to the "Applications" lookup tabs for more detail. Materials and designs will differ among brands, so plugs are not exactly alike. Always check with your OE service manual for proper installation and settings.

    Add-on Regulator
    Some alternators use an add-on type regulator that is mounted on the outside of the alternator housing.

    Alternator
    A belt driven device that creates electrical current for maintaining the charge state of the battery and the electrical requirements for the vehicle

    Ampere
    Commonly referred to as amps, this is an electrical unit of measure. Alternators are rated by the amp output capacity at a given voltage.

    Battery
    An electrical storage device used to supply electrical current for starting a vehicle.

    Charge Lamp
    A light in the vehicle instrument cluster that illuminates when the alternator is not charging or when there is a fault in the charging circuit.

    Core
    This is the old unit being removed from the vehicle.

    Diode
    Diodes are used in pairs (positive and negative) to change the alternator output from alternating current (AC) to direct current (DC).

    Direct Drive Starter
    This type of starter has the drive gear attached to the armature or utilizes the armature as the drive gear.

    External Fan (EF)
    This alternator design has a fan mounted on the outside of the alternator that directs air flow across the internal components for cooling.

    External Regulator (ER)
    Some alternators use a voltage regulator that is not attached to the alternator. It is usually found on the fender well.

    Flywheel
    This is a large gear mounted to the back of the crankshaft which turns the engine when the starter is cranking.

    Internal Fan (IF)
    This alternator design has two fans built together with the rotor inside the alternator that directs air flow across the internal components for cooling.

    Internal Regulator (IR)
    Some alternators use a built-in type regulator that is mounted on the inside of the alternator housing.

    Offset Gear Reduction Starter (OSGR)
    This type of starter uses an internal gear set used to increase torque. The internal gear sets are offset which means the drive gear and motor rotate on different axes.

    Permanent Magnet Starter
    This type of starter uses magnets for magnetic poles rather than coils of wire (field coils). These units are lighter in weight and smaller in size.

    Planetary Gear Reduction Starter (PGR)
    This type of starter is similar to the Offset Gear Reduction, however the gear sets are not offset which means the drive gear and motor rotate on the same axis.

    Rectifier
    This is an electrical component in the alternator that contains sets of diodes which are used to change the alternator output from alternating current (AC) to direct current (DC).

    Solenoid
    This is an electrical switch on the starter that once energized allows the starter to engage the drive gear into the flywheel during starting.

    Starter
    This is an electrical motor that cranks the engine by moving a drive gear into the flywheel, thereby rotating the crankshaft.

    Starter Drive
    This is the gear on the starter that engages the flywheel, causing the engine to crank.

    Voltage Regulator
    This is an electrical component used to maintain the proper charge state of the battery by regulating alternator output.
