1st Gen Tacoma: 5VZ-FE V6: timing belt due, ticking, or worried about the water pump

Checks, in order

1. Find the service history
   If there's no record of a belt job, assume it's due. Toyota's schedule for the 5VZ-FE is roughly every 90,000 miles; confirm the exact interval in your owner's manual.

2. Inspect through the timing cover
   Look for oil on the cover, cracks in the belt, missing teeth or frayed edges when the cover is off. Any of those means replace now.
   medium $ · under about $50
3. Replace belt, tensioner and water pump together
   Do the belt, tensioner, idler pulleys and water pump as a set since the pump is driven by the belt and sits behind the same cover. Also replace the front crank and cam seals if they're weeping.
   hard $$ · about $50 to $500
4. Use quality parts
   Stick to OEM or well-known OE-supplier parts. A cheap pump or belt can fail early and ruin the work.
