1990 Ford Aerostar Belt Tensioners

(Pulley Only) 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

Litens Automotive is the original equipment supplier of this tensioner for this Ford/Mazda application. The Litens replacement part meets all form, fit, and performance characteristics of the original equipment part (with the exception of not having the car manufacturer’s logo or part number applied to the part). The Litens replacement part maintains the round wire spring and internal damping components specified by the O.E. manufacturer. CAUTION: Some non-original equipment manufacturers have consolidated this part with a similar Ford/Mazda tensioner. They provide a spacer sleeve for the bolt and 2 extra bolts to assist in installation. While the part may be mounted on either engine design, the belt drives require different tension values and the nominal tensioner position once the belt is installed may not be correct. Best to always use the Litens original design for proper performance. 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.
• This belt tensioner has belt-length indicator marking to warn of excessive belt stretch.
• Durable Thermoplastic Pulley for long service life and performance.
• Professional Mechanics will change this tensioner in about 1 hour.
• 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, doing both together will extend accessory drive life and lower overall labor versus performing these services separately. Installation instructions included.

Litens was the Original Equipment (O.E.) supplier of this part and offers this upgraded part for the aftermarket. The Litens product meets or exceeds all original equipment form, fit, and function specifications for this Ford/Mercury/Mazda application. Tensioner upgrades include a redesigned steel pivot shaft to improve angularity and a change from steel to a plastic pulley. Unlike most Non-O.E. aftermarket tensioners, the Litens aftermarket tensioner maintains the OE damping system to ensure quiet, long-lasting performance. Choosing The Correct Replacement Part: Both the original equipment and Litens aftermarket tensioner use a round spring versus a flat spring. Supplied with a new mounting bolt. CAUTION: Some non-original equipment manufacturers have consolidated this part with a similar Ford/Mazda tensioner. They provide a spacer sleeve for the bolt and 2 extra bolts to assist in installation.

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
• This tensioner includes the required hardware for proper installation
