How to Replace Serpentine Belt Tensioner with Pulley 93-00 Ford Explorer

Difficulty: Intermediate · About 40 min · Ford Explorer

Replace the serpentine belt tensioner, including its pulley, on a 1993-2000 Ford Explorer.

Steps

1. Disconnect the battery and note the belt routing

   Find the belt routing diagram near the radiator before touching anything, then disconnect the negative battery terminal with an 8mm wrench.

2. Move the intake hose aside

   Loosen its clamps, unclip the air filter box cover, and tuck both out of the way.

3. Remove the serpentine belt

   Use a 3/8 inch drive ratchet handle on the tensioner to push it down and relieve tension, then slip the belt off.

4. Swap the tensioner

   Unbolt the old tensioner with a 13mm wrench, bolt the new one on in its place, and tighten it firmly.

5. Inspect and reinstall the belt

   Check the old belt for cracks or fraying before reusing it, then follow the routing diagram while using the 13mm wrench on the tensioner to walk the belt back over every pulley.

6. Reconnect the battery

   Give every pulley one more look, reattach the intake hose, then reconnect the negative battery terminal.

Check your vehicle’s repair manual for exact specifications and fit.
