Detailed Description

Dayco 84091 is a timing component kit for Toyota engines that need coordinated belt-drive service parts in one application-specific package. This kit is listed for 1995-2004 Toyota Tacoma, 2000-2004 Toyota Tundra, 1996-2002 Toyota 4Runner, and 1995-1998 Toyota T100. Use it when servicing the timing belt system on these Toyota models and you need the camshaft belt tensioner and idler specified for the application. The part number 84091 is also a useful reference when comparing replacement options for Toyota Tacoma timing component kit, Toyota Tundra timing belt component kit, and Toyota 4Runner timing service parts.

What It Is Used For

  • Replacing worn timing belt support components on Toyota Tacoma, Tundra, 4Runner, and T100 engines
  • Addressing belt noise from a worn tensioner or idler
  • Correcting timing service issues caused by aging belt-drive components
  • Restoring proper belt tracking and tension control during timing belt maintenance

Installation Notes and Tips

Verify engine code and application details before installation, since timing components are engine-specific. This kit includes the camshaft belt tensioner and idler, and the hydraulic actuator is not included. Inspect the belt path, seals, and related wear points during timing service, and follow the vehicle service manual for torque and timing alignment procedures.

Quality Assurance

Dayco Timing Component Kit 84091 is cataloged for direct fitment on the listed Toyota applications and is identified by a known OE-style replacement part number for service matching.
