BMW F30 340i Serpentine Belt

SKU F30-340I-BELT
Price

$14.99

The serpentine belt drives the alternator, power steering pump, and air conditioning compressor from the crankshaft pulley. A cracked or worn belt can slip, squeal, or snap, leaving accessories inoperable.

This belt is sized to fit the BMW F30 340i (N55 turbo inline-six), matching the factory rib count and length for correct tensioner engagement.

Durable, crack-resistant material delivers quiet, reliable power transfer for the life of the belt.

Reference: OE/interchange ULTRA-POWER

"The socket set is top-tier quality. Heavy-duty steel that handles real torque without slipping. Better than the big box store brands honestly."
