Description

The Dayco 89234 is an automatic belt tensioner assembly designed for serpentine belt systems. It features Dayco's patented flat spring design, which helps to minimize operating range variation and reduce the risk of premature accessory bearing failure due to excessive tension. This tensioner also lessens the likelihood of belt noise and slippage associated with low tension. Constructed with a heavy-duty cast aluminum spring case and arm, this tensioner resists cracking and fatigue, offering enhanced strength and reducing the risk of distortion. Premium thermoplastic rubber spring slot plugs and rubber O-ring seals are incorporated to prevent contaminants from entering the assembly. The zinc-coated mounting bolts are resistant to rust. Key specifications include a serpentine belt type, automatic mounting, a pulley diameter of 76mm, a flat pulley type, a pulley width of 22mm, and a clockwise operating direction. This tensioner assembly is compatible with a wide range of vehicles, including various models of Buick Skylark, Oldsmobile Cutlass Calais, Chevrolet Beretta, Oldsmobile Cutlass Supreme, Pontiac Grand Prix, Oldsmobile Achieva, Chevrolet Cavalier, Pontiac Sunfire, Pontiac Grand Am, Chevrolet Malibu, and Oldsmobile Alero from model years 1987 through 1999. Specific notes regarding "1st Design" or "w/o Integral Bracket" are provided for certain applications.
