Continental 4PK819ELAST Serpentine Belt - Air Conditioning

Continental Metric Stretch Belt 4PK819ELAST

The Continental Metric Stretch Belt 4PK819ELAST is a serpentine-style accessory drive belt built for air conditioning applications that require a stretch-fit design. It uses EPDM compounds and a polyamide tensile cord to stretch during installation and recover to maintain tension in service.

For BMW and Subaru owners searching for a metric stretch belt for air conditioning service, this Continental belt is identified by its functional part number and ELAST suffix. The 4PK819ELAST designation helps distinguish it from standard accessory drive belts when matching the correct OE-style application.

Key Features

• 4-rib belt profile with a 0.53 in top width
• 32.24 in belt length for listed air conditioning applications
• EPDM construction for durability in accessory drive use
• Polyamide tensile cord supports stretch installation and tension recovery
• ELAST suffix identifies Continental stretch belt construction
• Designed for metric stretch belt applications in BMW and Subaru vehicles

Product Details

Continental’s Metric Stretch Belt line is built around OE-style stretch-belt technology for vehicles that use a non-adjustable accessory drive setup. This 4PK819ELAST belt is specified for air conditioning positions on select BMW 550i, 650i, X5, X6, and 750i/750Li applications, as well as 2019-2021 Subaru WRX air conditioning service. The belt’s 4-rib design and 32.24-inch length are key identifiers when selecting the correct replacement.

This part cross-references Subaru 23780AA111 and BMW 11287552084 for the same application.

What It Helps Address

• Cracked, glazed, or worn air conditioning drive belts
• Loss of proper belt tension on stretch-fit accessory drives
• Squealing or slipping from an aging A/C belt
• Incorrect belt selection when replacing an ELAST-style belt
• Service needs on BMW and Subaru air conditioning drive systems

Installation Notes and Tips

Use the part number, rib count, and length to confirm the correct stretch belt before installation. Because this is a stretch belt, it is identified by the ELAST suffix and is intended for applications that rely on belt recovery to maintain tension. Verify the vehicle’s air conditioning drive configuration against the listed fitment before ordering.
