VAICO All-Wheel Drive Coupling Pump

The VAICO All-Wheel Drive Coupling Pump (also called an AWD coupling oil pump, Haldex coupling pump or rear differential coupling pump) is a replacement part for on-demand all-wheel drive systems. It builds the hydraulic pressure that the coupling needs to send torque to the rear axle when the front wheels lose traction.

Key Features:

• Replacement pump for the all-wheel drive coupling hydraulic circuit
• Made to restore the coupling's oil pressure and torque transfer
• Made to match the form, fit and function of the original part
• Part of the VAICO range of replacement parts. VAICO is a brand of the Original Equipment Manufacturer (OEM) supplier Vaico, based in Germany.

A worn or failing coupling pump can cause AWD warning lights, poor traction, or an AWD system that does not engage. Installing a new pump helps restore normal all-wheel drive operation. Choose the correct child item for your application from the options listed on this page.
