Detailed Product Overview

URO part number 1192000270 is an accessory drive belt tensioner designed for serpentine belt systems on select Mercedes-Benz models. The aluminum housing is intended to withstand engine heat and vibration, while the sealed bearing supports consistent pulley operation in demanding underhood conditions. With a smooth contact surface and one pulley, this tensioner is built to maintain proper belt tracking and tension across the engine speed range.

Compatible With 1994-1995 Mercedes-Benz E420, 1994-1995 Mercedes-Benz S420, 1994-1995 Mercedes-Benz S500, 1994 Mercedes-Benz E500, 1992-1993 Mercedes-Benz 400E, 1993 Mercedes-Benz 400SEL, 1992-1993 Mercedes-Benz 500E, 1993 Mercedes-Benz 500SEC, 1992-1993 Mercedes-Benz 500SEL, 1992 Mercedes-Benz 400SE, and 1990-1992 Mercedes-Benz 500SL. This part number 1192000270 also cross-references VAICO V30-0666 for the same application.

What This Tensioner Helps Address

• Serpentine belt squeal caused by weak or inconsistent tension
• Belt misalignment from worn pulley or tensioner components
• Visible belt flutter or unstable accessory drive operation
• Noisy bearing operation from a worn tensioner pulley
• Premature belt wear related to poor belt tracking

Installation Notes and Tips

Verify engine range notes before ordering, since several Mercedes-Benz applications are limited by engine number. Confirm pulley dimensions and belt routing against the original part before installation. Inspect the serpentine belt, idler pulleys, and accessory drive components at the same time so the new tensioner can operate with proper alignment and load.
