1989 Chevrolet G10 Belt Tensioners

The Dayco automatic belt tensioner features Dayco’s original, patented flat spring design to provide less operating range variation. It reduces the risk of premature accessory bearing failure due to high tension and lessens the risk of belt noise and slippage – or poor performance caused by low tension. A PTFE string wound within the spring resists abrasion and dampens noise. Dayco’s tensioner is also designed with a heavy-duty cast aluminum spring case and arm, which helps resist cracking and fatigue and offers additional strength, lessening the risk of distortion. Additional premium thermoplastic rubber spring slot plugs and rubber O-ring seals help keep contaminants out and zinc coated mounting bolts resist rust.

Product Features:

• Endures the toughest conditions while promoting quieter performance and longer life
• Features a steel pivot tube on specific designs for enhanced stability
• Built to outperform and outlast competitive OE parts

Product Features:

• Comprehensive line includes parts to fit cars, vans, SUVs and light trucks, domestic and import (European and Asian)
• Manufactured using the same or improved technology and quality materials as the Original Equipment Manufacturer (OEM) part, assuring a factory match
• Patented labyrinth seal protects internal components to meet or exceed OE life expectancy requirements
• Patented vibration-damping system absorbs extreme vibration to improve tensioner, as well as belt and accessory, life
• Torsional round spring design provides reliability as well as consistent tension
• Comprehensive line includes parts to fit cars, vans, SUV’s and light/heavy-duty trucks.

This Litens’ tensioner is manufactured by the Original Equipment (O.E.) supplier of this popular General Motors tensioner. The Litens aftermarket part meets original equipment specifications in form, fit, and function. While the many aftermarket tensioner suppliers remove the original damping element and change the pulley from steel to plastic, the Litens “round spring” tensioner maintains these original equipment components required for optimal performance and life. O.E. Exact – Original Equipment manufacturers prohibits the use of their part number or logo on parts sold to other customers. Therefore, the Litens aftermarket part may have minor cosmetic differences but still be exact in performance and design. Note: This tensioner was supplied to the original equipment manufacturer by two different part suppliers. The tensioner being replaced may look different, but this Litens part replaces both variations. Litens is the world’s largest supplier of original equipment (O.E.) power transmission products. At Litens, we design systems that are more efficient, resulting in tangible fuel economy/emissions benefits. Litens holds over 2000 patents and continues to respond to the ever-changing automotive industry by investing heavily in new technology, facilities, and people. 90% of our line is made of products coming from the OE manufacturer, which makes the Litens Tensioning Products portfolio the purest OE tensioning line in the North American aftermarket._

Product Features:

• Manufactured by the original equipment part supplier to ensure proper form, fit and performance
• Internal “round spring” technology to provide constant belt tension and alignment throughout its service life. The internal damping design provides quiet, smooth, system performance.
• Installation instructions included.
• Heavy Duty Steel Pulley
• Professional Mechanics will change this tensioner in 20 minutes
• Due to the fact that belts and tensioners have similar Original Equipment “design life targets”, it is often a best practice to replace the belt tensioner when replacing a worn or broken belt. Belt removal is required to change the tensioner. Therefore, d

Dorman’s Belt Tensioner Pulley is engineered to maintain tension on the serpentine belt for the life of the belt–thereby keeping the alternator charging, the water pump running, and the power steering pump and A/C compressor operating properly. They feature a high-quality double-sealed bearing to resist damage from contaminants. Replacement prevents belt slip and eliminates squeak, squeal or groaning noise associated with a worn belt tensioner pulley.

Product Features:

• Steel or plastic construction for long-lasting durability against heat, shock and corrosion
• Replacement stops squeak, squeal or groaning noise associated with a worn Belt Tensioner Pulley
• Direct replacement for a proper fit every time
• Vehicle try-on testing and rigorous materials testing to ensure high-quality performance
