Pump Kit – GM (19387230)

Factory part number 19387230: a pump kit supplied by GM. It is catalogued under Motors & Pumps > Pumps.

• A pump that runs but does not move fluid may be a priming problem rather than a failed unit, particularly on a dry system.
• Blower noise that changes with speed points at the cage, while noise that stays constant points at the bearings.
• Where a motor is controlled by a module, the module fails as often as the motor and the symptoms overlap almost completely.

Washer and coolant pumps usually fail at the seal rather than at the motor, and a leaking seal will have contaminated the connector. Torque figures belong to the fastener and the joint rather than to the part, so the factory procedure is the reference rather than a general rule.

Confirm the number before you order, because a near match will bolt on and still be wrong. Send the VIN if the old marking has gone. In stock and sent from the US in one to two business days, free delivery over $59.
