1st Gen Tacoma Timing Belt Replacement Guide

Timing Belt Replacement: 1st Gen Tacoma 3.4L V6

The timing belt on the 5VZ-FE 3.4L V6 must be replaced every 60,000 miles. This is the single most important maintenance item on 1st gen Tacomas. A failed timing belt will cause catastrophic engine damage.

Replace These Items Together

• Timing belt
• Water pump

Key Tips

• Always use the Toyota OEM kit or Aisin brand (they make the OEM)
