Continental Idler Pulley

Vehicle Specific

Part Number: 4123
Features & Benefits

This Continental OETechnology Series™ belt tensioner is manufactured by the original equipment (O.E.) supplier for this application and offers this upgraded part for the aftermarket. The Continental OETechnology Series™ 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 Continental OE Series® belt tensioner maintains the OE damping system to insure quiet, long-lasting performance. Choosing the correct replacement part: both the original equipment and Continental OE Series® belt 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. 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 Continental OE Series® original design for proper performance.

  • Manufactured by the original equipment part supplier to insure proper form, fit, and performance
  • Internal "round spring" technology to provide constant belt tension and alignment throughout its service life
  • Instructions included
  • Heavy duty glass reinforced polymer pulley for optimized dimensional control and running surface durability
  • Changing the belt and tensioner together can extend accessory drive life and lower overall labor
  • Installation instructions included
