SOURCE: cant find drive belt tensioner bolt to loosen serpintine belt

The serpentine belt tensioner / pulley is on the front of the engine, and part of the belt 'routing'.

Its job is to put tension on the belt as it drives the other devices like the power steering pump, water pump, air conditioning compressor.

It is an aluminum casting that mounts with a single bolt to the engine. The pulley is attached to the arm.

There are a few ways to move / pry the arm inwards, thus releasing the tension on the belt for removing/installing: grab on the pulley bolt (15mm?) with a wrench, or some later models have an opening for a 3/8th socket wrench to attach to directly without a socket.

SOURCE: Timing Belt Tensioner bolt broken off.

if this happened you bent the valves in the engine and the cylinder head must be removed, here are full instructions for a timing belt replacement.

Required tools:
13mm open end wrench 10mm shallow and deep socket 8mm socket long flathead screwdriver 17mm deep socket T50 torx socket 1/4", 3/8ths and 1/2" ratchets and extensions E10 inverted torx sockets 6mm Allen wrench 15mm open end wrench 7mm socket 12mm open end wrench 14mm socket 12mm socket 8mm, 9mm and 10mm Allen head sockets 19mm socket pry bar needle nose pliers
If you are doing this because your timing belt broke you will also need to buy a complete cylinder head, head gasket set, and both idler pulleys. ALL DAEWOO MODELS WILL BREAK THE INTAKE AND EXHAUST VALVES WHEN THE TIMING BELT BREAKS.
Start by removing the air cleaner assembly from the throttle body, remove the air filter and housing jack up the vehicle and remove the wheel, remove the plastic shielding in front of the accessory drive belt assembly, remove the accessory drive belt, place a jack with a block of wood on top underneath the engine oil pan remove the front engine mount, remove the crank shaft pulley ( the 4 Allen head bolts only not the 17mm bolt in the center.) remove the metal plate behind the engine mount bracket on the engine, remove the plastic timing belt cover 3 clips on top 2 10mm bolts on bottom. Rotate the engine until the #1 cyl. is at Top Dead Center on the compression stroke or line up the crankshaft timing mark with the mark on the inner timing belt cover ( notch in cover with notch in pulley) on the camshaft pulleys -- ( intake cam line up the line on the pulley with the line on the inner cover)( exhaust cam line up the arrow on the pulley with the arrow on the inner cover) loosen the 13mm bolt in the belt tensioner and using the Allen wrench rotate the tab until there is slack in the belt. Remove the belt. At this time I would recommend you replace the water pump, both plastic idler pulleys as they tend to overheat and lockup, and the belt tensioner. Make sure all your marks are lined up, you may need a helper to hold the Exhaust Cam in place as it tends to move during belt installation. Put the timing belt underneath the crankshaft pulley, install the belt leaving the intake cam for last and NO BELT SLACK on the right side between the crank and the exhaust cam. Once the belt is installed rotate the crankshaft over 2 revolutions and make sure is rotates freely, and your timing marks are aligned perfectly if not the engine will not run properly, tension the belt as needed. Installation is the same as removal.

To clarify, on the DOHC engine, the intake cam gear has a line on it, and the exhaust cam gear has an arrow on it. These should be lined up with the corresponding line and arrow on the VALVE COVER, pointing straight up. I just went through this process over the weekend, and spent quite a bit of time looking for these marking as I had removed the valve cover. Once I found them, it was plain and simple.
In addition, be sure to not over tighten the belt when reinstalling. The tensioner has markings on it for "old" and "new". DO NOT adjust past "new", as the car will sound like a jet engine, and the belt will not last for very long.
One more item that you may as well replace while you are in there is the cam position sensor if you have not already, as there have been issues with them, and the timing housing has to be opened to get to it

1997 Jeep cherokee larado squeals replaced the drive belt a few times and it keeps tearing


Inspect the belt tensioner for the following conditions:
Noise
  • If the belt squeals, the tensioner force may be insufficient. Check the belt length gauge, if the length is correct, replace the tensioner.
  • If the tensioner clatters or rattles during engine operation, there may be internal interference or wear. Replace the tensioner.
  • If the belt chirps, you may have a worn pulley or tensioner or cracks in the tensioner bas or arm. Check the mounting bolts, if they are okay, replace the tensioner.
Sticking or Seized Tensioner or Idler
  • If the tensioner does not operate smoothly or doesn't move, you may have: internal thrust surface damage/wear, internal damage/wear, or a broken spring, replace the tensioner.
Appearance
  • Inspect the tensioner arm for cracks or other damage. If the tensioner is broken, it should be replaced.
  • Look for excessive tensioner movement at idle, which can indicate internal wear, an out-of-round pulley or loose mounting bolts. Check the mounting bolts, it they are in good condition, replace the tensioner.
  • Make sure the tensioner is not tilted or misaligned. Also make sure a gap exists between the tensioner arm and base. If you notice a problem, check the mounting surface, it the surface is okay, replace the tensioner.
Belt Tracking
  • If the belt does not track properly on the pulley tracking surface, you'll need to troubleshoot the problem. Check the mounting bolts and the system alignment. Then, make sure the correct belt is being used for the vehicle. If all of these things are intact, replace the tensioner.
Belt Length Indicator
  • A belt length indicator is built into each tensioner.
  • The gauge identifies the effective operating range of the tensioner.
  • It consists of a pointer and either two or three length marks.
    • On a three-mark gauge minimum belt length, maximum belt length and ideal belt length are indicated.
    • On a two-mark gauge only minimum belt length and maximum belt length are indicated.
    • Ideal belt length on a two-mark gauge is generally half way between the minimum and the maximum.
  • When a belt wears and stretches with age the tensioner will move towards the maximum belt length to maintain proper tension.
  • As the pointer nears the maximum length mark, replace the belt.

Remove and replace Alternator on 2005 chevrolet cobalt


All you really need to do is disconnect the cables directly attached to the alternator, release the tension on the serpentine belt, and remove the bolts holding the alternator on. to install a new on, just to the opposite. you might want to loosen the tension first if that makes it easier to disconnect the wire(s) from the alternator. should take about 1-2 hours tops for $100.

Timing belt


TIMING BELT & SPROCKETS R & I
NOTE: Some procedures may differ slightly due to engine
construction.
Removal
1) Remove all necessary air ducts. Position No. 4 piston at
TDC of compression stroke. Align timing marks. See Fig. 2. Remove fan
and fan shroud. Remove belts. If necessary, remove radiator and
splashguard.
2) Prevent engine from rotating and remove crankshaft timing
pulley retaining bolt. Remove upper and lower timing belt covers.
Remove spring from tension pulley. Loosen adjusting bolt and move
pulley toward water pump. Remove timing belt.
CAUTION: Ensure pistons are at TDC when rotating camshaft or damage
may result.
Inspection
1) Handle timing belt carefully. Avoid twisting or kinking
belt. Do not allow belt to become contaminated by water, oil, dirt or
other contaminates. Inspect belt for cracks or damage. If necessary,
replace.
2) Measure tension pulley spring length and force. Spring
length should not exceed 2.76" (70.2 mm) and spring force should not
be less than 197-347 lbs. (27-48 kg).
3) Replace tension pulley spring if not within specification.
Installation
1) Pull tensioner fully toward water pump side and
temporarily tighten retaining bolt. Ensure No. 4 cylinder is at TDC on
compression stroke by rotating crankshaft until keyway aligns with
mark on front crankshaft seal housing (12 o'clock). Rotate camshaft
until timing mark on cam gear (arrow) aligns with mark on upper
camshaft cover (notch). See Fig. 2.
NOTE: When timing marks are aligned as stated above, No. 4 piston
is at TDC on compression stroke.
2) Position timing belt over crankshaft sprocket, oil pump
sprocket, camshaft sprocket and tensioner in that order. Ensure belt
is positioned in sequence given and without slack between sprockets.
Loosen tension sprocket adjusting bolt allowing spring tension to
tighten belt. Tighten adjusting bolt temporarily.
3) Temporarily install crankshaft pulley bolt and rotate
crankshaft 2 complete revolutions in opposite direction of engine
rotation, until marks on crankshaft and front oil seal retainer are
aligned again. See Fig. 2. Loosen tensioner lock bolt, allowing
tesioner spring to fully adjust tension. Tighten tensioner lock bolt.
4) Install timing belt covers. To complete installation,
reverse removal procedures. Tighten all bolts to specification. See
TORQUE SPECIFICATIONS table at end of this article.

I am in the process to install a new alternator for which I need to loosen the belt. Is there a tensioner and what does it look like ?


Don't know what size of motor you have but this should help you:

Removal & Installation
  1. Loosen the accessory-to-mounting bracket bolt(s) and adjusting bolt.
  2. Rotate the accessory to relieve belt tension.
  3. Slip the drive belt from the accessory pulley and remove it from the engine.

If the engine uses more than one belt, it may be necessary to remove belts that are in front of the belt being removed

To install:

If the engine uses more than one belt, it may be necessary to remove belts that are in front of the belt being removed


  1. Place the new belt over the crankshaft or drive pulley and stretch over the driven (accessory) pulley.
  2. If removed, install the other belts in the same way.
  3. Adjust the belts to the proper tension.
  4. Tighten the adjusting and mounting bolts.

Models equipped with the V6 engine and most 1987-94 engines use a single (serpentine belt) to drive all engine accessories. The serpentine belt driven accessories are rigidly mounted with belt tension maintained by a spring loaded tensioner assembly. The belt tensioner has the ability to control belt tension over a fairly broad range of belt lengths. However, there are limits to the tensioner's ability to compensate for varying lengths of belts. Poor tension control and/or damage to the tensioner could result with the tensioner operating outside of its range.

To replace the belt push (rotate) the the belt tensioner and remove the belt. Use a 15mm socket on the 4-cyl. engines and a 3/4 in. open end wrench on the V6 engines.
