Fan belt adjuster - Cars & Trucks

Hi there , there should be a adjuster on the alternator, unless it's a serpentine belt, if a serpentine belt then you will need a new tension bled idler, hope this helps.

1. Install lower timing belt cover.
2. Install upper timing belt cover.
3. Install power steering drive belt and adjust belt tension.
4. Install fan pulley.
5. Install generator drive belt and adjust belt tension.
6. Install A/C drive belt and adjust belt tension.
7. Install splash guard.
8. Install fan and fan shroud.
9. Install 4 fan bolts. Tighten to 24 ft lb (33 Nm).
10. Install fan shroud mounting bolts.
11. Install fresh air duct.
12. Connect hose to resonance chamber.
13. Connect battery negative cable.

the adjustment is done by the idler pulley. loosen the nut that holds the pulley on. adjust on or off by the bolt immediately behind the idler pulley. most adjustments are right when the longest section of belt between 2 pulleys can be depressed about the thickness of the belt

ARE YOU TALKING ABOUT THE FAN BELT? IF YOU ARE THEN YOU NEED TO ADJUST THE TENSIONER. WHICH WILL ADJUST YOUR FAN BELT AUTOMATICALLY

No, no timing adjustment should even be considered. Maybe the belt is too tight. Have the tensioner pulley checked, if this is a serpentine belt.
You might try loosening it just a bit, if possible, and see if previous performance returns.

1. Align marks on camshaft pulleys with alignment marks on seal plate.
2. Install timing belt. NOTE: No looseness should exist on the tension side and at the camshaft pulleys.
   
3. Loosen tensioner lock bolt.
4. Turn crankshaft 2 revolutions in direction of rotation and check that timing marks are still in alignment.
5. Tighten timing belt tension lock bolt to 27-38 ft lb (32-52 Nm).
6. Apply a force of 22 lbs to timing belt between camshaft sprockets.
7. Belt deflection should measure 0.30-0.33 in (7.5-8.5 mm)

1. NOTE: Replace tensioner spring if timing belt deflection is excessive.

sounds like your timing belt may have slipped or snapped a ceased timing belt adjuster could cause this check your timing belt and adjuster and all belt adjustment pulleys before you fix the valves otherwise its bound to happen againalso make sure your engine oil is full
