Product Details

Roadmax Automotive V-Ribbed Belt (Standard) part number 4K388AP is engineered to match the specified accessory drive routing for the listed vehicles. It is a practical replacement choice for owners servicing a 2007-2008 Mitsubishi Outlander power steering belt, a 2004-2007 Cadillac CTS air conditioning belt, or a 1992-1994 Nissan Maxima power steering and water pump belt. The same part number 4K388AP also applies to select Chrysler Sebring and Dodge Stratus power steering applications, plus Mitsubishi Montero Sport fan and alternator drive service.

This part cross-references Gates K040388 and Dayco 5040388 for the same application.

What This Belt Helps Address

  • Squealing or chirping from a worn accessory drive belt
  • Cracking, glazing, or visible wear on the belt ribs
  • Loss of proper drive to power steering, A/C, fan, alternator, or water pump systems
  • Belt stretch that affects routing and tension retention
  • Service replacement for a belt matched to the original drive length and rib count

Installation Notes and Tips

Verify belt routing, rib count, and length against the original belt before installation. Inspect pulleys, tensioners, and idlers for wear or misalignment, since those conditions can shorten belt life. Confirm the accessory position listed for your vehicle, such as power steering or air conditioning, before ordering 4K388AP.

Quality Assurance

Roadmax positions this standard V-ribbed belt as a value-focused replacement for customers who want quality construction without stepping up to a premium belt line. EPDM belt material and polyester cord reinforcement support consistent service in the specified applications.
