  • Double high temperature seals to assure peak bearing performance
  • Grooved, steel pulley that contains a specially formulated e-coating, comparable to OE plating that resists corrosion and wear resistance under harsh environments
  • Meets or exceeds OE quality

Daycon Tensioner Pulley

Great part. Super easy install. Highly recommend the tensioner tool for installation on a 1997 Mustang.

This does NOT work on a Ford 6.0L diesel engine. The idler is one rib too narrow, and is not the same diameter as the one on the engine.

This does NOT work on a Ford 6.0L diesel engine. The idler is one rib too narrow, and is not the same diameter as the one on the engine.

You need to get the 3.5" idler to work on the Ford 6.0L diesel engine, even though this shows as compatible with the engine on the website.

          Top Tip: Measure the diameter and width of your old one first before ordering.

          This fits a '98 Mustang 3.8 V6 TENSIONER pulley. You will need to add a washer behind this pulley or it will rub on the tensioner arm. But it does work.

                    I had a squeaky pulley, bought this to replace it. It was not the same, pulley size and bearing size. Would recommend to anybody having to replace the pulley due to bearing failure to replace just the removable bearing. Much cheaper.

                    Got this tensioner pulley and installed. Found that the pulley didn't match the orginal one and it was a loose fit. Took it back with the orginal one. I was told the that was the one that it called for but, did not match. Just got my money back and went else where.

                          For help with your project, I recommend purchasing a Haynes repair manual specifically for your vehicle. This should be able to assist you further into detail on how to repair or replace specific parts.
