1998 GMC P3500 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

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

This Litens tensioner is manufactured by the Original Equipment (O.E.) supplier of this popular General Motors tensioner. This “O.E. Exact”* part for the aftermarket meets all original equipment form, fit, and function specifications. (*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: The dust shield protecting the bearing has been upgraded from the original design. Choosing The Correct Replacement Part: Both the original equipment and Litens aftermarket tensioner use a round spring versus a flat spring and are marked “Made in Canada”. This tensioner is supplied with a new OE style mounting bolt. 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.
• Installation instructions included.
• Heavy Duty Glass Reinforced Polymer Pulley for optimized dimensional control and running surface durability
• Professional Mechanics will change this tensioner in approx. 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

Litens was the Original Equipment supplier (O.E.) of this part and offers this “O.E. Exact”* part for the aftermarket. This popular tensioner designed for General Motors vehicles, looks, fits, and performs like the original part being replaced. Unlike many Non-O.E. aftermarket tensioner suppliers, the Litens part maintains the original equipment steel pulley and internal damping feature for optimal performance and life. Installation Tip: Note the Litens aftermarket tensioner maintains the inset square wrench “lift feature” on the tensioner face to facilitate belt tension release during installation. This lift-feature makes installation easier on the assembly line or in the garage. *OE Exact – Original Equipment manufacturers prohibits the use of their part number or logo on parts sold to other customers. Therefore, the Litens integrated bolt/washer versus 2 separate components.
