Yes with a socket and ratchet you will need someting to allow you to put pressure on it like a piece of pipe to use like a breakover bar,

Adjust tension on fan belt 91 geo storm


Posted 3 time now (STORM is, a Isuzu Impulse)
and not ONE TIME>>" direction for loose. easy !


the early 1991, was 1.6L and has no SERP
end SERP:
they run old fashion V belts, did you even look first to see what is there?

its not a serp, in 1991.
but many posters here get year wrong, and that.
ISUZU engines per this list
1.6 L 4XE1 DOHC I4 (US, Canada only) 12valve
1.6 L 4XE1W turbo DOHC I4, 16valve.
1.8 L 4XF1 DOHC I4
the fan V belt , IIRC is the water pump,fan and alternator V belt.
if that is the belt you are alluding to then the alternator
pivots and adjust to tension it.

https://www.youtube.com/watch?v=RwPFTGnb5NI

now ill quote the fsm on the 1.6L with v belts.
here we go, what you mean by fan , my guess is Alternator belt, its called that because the ALT is the adjustment.



Loosen the component-to-mounting bracket bolts.

Use a belt tension gauge (J-23600-B or equivalent) to determine proper belt adjustment; place the gauge at the center of the belt between the longest span.

Applying belt tension pressure on the component, adjust the drive belt tension to the correct specification:

For 1990 and 1991 vehicles, adjust the power steering pump belt to 145 lbs on vehicles with A/C or to 90 lbs on vehicles without A/C.

For 1990 - 1992 vehicles, adjust a new alternator belt to 140-180 lbs or a used belt to 110-150 lbs.

For 1992 power steering pump belts and 1993 vehicles, adjust the belt so that 22 lbs of thumb pressure produces the specified belt deflection at the center of the belt, between 2 pulleys. Under proper belt tension a new belt should deflect about 0.31-0.47 in. (8-12mm) or a used belt about 0.28-0.43 in. (7-11mm).

While holding the correct tension on the component, tighten the component-to-mounting bracket bolt.

When the belt tension is correct, remove the tension gauge."
end quote, if not clear after Ive posted all 3 engines, say so or ask a question.

I just replaced the alternator belt on my 96 Isuzu trooper and after tightening everything and starting the engine ,neither the fan nor the alternator will turn unless I do so by hand


did belt fall of first or you took it off. first.???????????????????????????????
no engine size stated 2.8L or 3.1L Usa.
belts vary by engine,
causes.
belt mis-routed,did you make a drawing before starting.oops
or you set the tension wrong? read the book or guess?
or the auto tensionor is bad. (we always check this 1st.

now i read your fsm book on serp belt.
its a serp right>?

"some of the V6 engines are equipped with a serpentine belt and automatic belt tensioner. The tension is maintained by a spring loaded pulley/tensioner. The indicator mark on the moveable portion of the tensioner must be within the limits of the slotted area on the stationary portion of the tensioner. Any reading outside the limits indicates either a defective belt or wrong SIZE belt or bad tensioner."

question 3
did you take old belt and match it side to side
with the old, and are same size.
if not FAIL.
assumes old belt not lost or run to total destruction. (im blind tell me)
q4: did you put a a/c belt on a non a/c cars
see dotted line below, that be 2 type belts.

I'm replacing the serpentine belt on a 2001 cherokee sport 4.0 and the belt tension adjustor does not seem to be loosening the pulley. got the old belt off, but cannot get the new belt back on.


alldata.com
page 1, line 1 (serp)
Tension is maintained using an automatic tensioner pulley assembly. The drive belt is tensioned by adjusting the position of the idler pulley, accomplished by moving the adjuster bolt on the idler mechanism.

here, pasted in whole.

Serpentine Belt Because serpentine belts use a spring loaded tensioner for adjustment, belt replacement tends to be somewhat easier than it used to be on engines where accessories were pivoted and bolted in place for tension adjustment. Basically, all belt replacement involves is to pivot the tensioner to loosen the belt, then slide the belt off of the pulleys. The two most important points are to pay CLOSE attention to the proper belt routing (since serpentine belts tend to be "snaked'' all different ways through the pulleys) and to make sure the V-ribs are properly seated in all the pulleys.
Although belt routing diagrams have been included in this section, the first places you should check for proper belt routing are the labels in your engine compartment. These should include a belt routing diagram which may reflect changes made during a production run.
  1. Disconnect the negative battery cable for safety. This will help assure that no one mistakenly cranks the engine over with your hands between the pulleys, and that the cooling fan cannot activate while servicing the belt(s). NOTE Take a good look at the installed belt and make a note of the routing. Before removing the belt, make sure the routing matches that of the belt routing diagram. If for some reason a diagram does not match (you may not have the original engine or it may have been modified), carefully note the changes on a piece of paper.
  2. For tensioners equipped with a 1/2 in. (13mm) square hole, insert the drive end of a large breaker bar into the hole. Use the breaker bar to pivot the tensioner away from the drive belt. For tensioners not equipped with this hole, use the proper-sized socket and breaker bar (or a large handled wrench) on the tensioner idler pulley center bolt to pivot the tensioner away from the belt. This will loosen the belt sufficiently that it can be pulled off of one or more of the pulleys. It is usually easiest to carefully pull the belt out from underneath the tensioner pulley itself.
  3. Once the belt is off one of the pulleys, gently pivot the tensioner back into position. DO NOT allow the tensioner to snap back, as this could damage the tensioner's internal parts.
  4. Now finish removing the belt from the other pulleys and remove it from the engine.
To install:
  1. While referring to the proper routing diagram (which you identified earlier), begin to route the belt over the pulleys, leaving whichever pulley you first released it from for last.
  2. Once the belt is mostly in place, carefully pivot the tensioner and position the belt over the final pulley. As you begin to allow the tensioner back into contact with the belt, run your hand around the pulleys and make sure the belt is properly seated in the ribs. If not, release the tension and seat the belt.
  3. Once the belt is installed, take another look at all the pulleys to double check your installation.
  4. Connect the negative battery cable, then start and run the engine to check belt operation.
  5. Once the engine has reached normal operating temperature, turn the ignition OFF and check that the belt tensioner arrow is within the proper adjustment range.

2005 dodge stratus r/t tensioner pulley and belt issue


ARE YOU POSITIVE THE SERP BELT IS NOT SLIPPING OFF THE CRANK PULLEY? I USE A STRIP OF DUCT TAPE TO HOLD IT ON THE PULLEY AS I FEED THE REST AROUND.

YOU SHOULD END UP WITH THE BELT TIGHT AND MUST THEN (USING A SERPENTINE IDLER PULLEY TOOL) RELEASE TENSION IN ORDER TO GET IT OVER THE CLOSEST, MOST CONVENIENT PULLEY...THEN RELEASE TOOL TENSION AND BELT SHOULD BE ON.
***FEEL FOR PROPER TENSION ON IDLER PULLEY (SERP BELT) IT MAY BE SHOT

How to replace 2002 camry drivebelt


to replace the serp belt you'll need to release the tensioner in the system remove the old and install the new the issue always is the proper routing for the belt follow the diagram under the hood watch the routing as you remove the old belt if a diagram isn't available under your hood request one upon the purchase of your new belt sometimes the parts store will loan or rent you the tools you need for belt replacement

How simple is it to change a alternator belt on subaru svx?


  1. Removing the Serpentine Belt
    • 1 Park your Subaru on a level surface and open the hood.
    • 2 Disconnect the ground (black) battery cable using a wrench. This will prevent the cooling fan from activating.
    • 3 Locate the serpentine belt routing diagram in your engine compartment and compare it to the actual routing of the installed belt. Make sure the routing on the label matches the actual routing. If they do not match or there is no label, note the actual routing on a piece of paper for later reference.
    • 4 Locate the belt tensioner pulley on your Subaru model. If the tensioner is equipped with a squared hole, use a large breaker bar with a 1/2-inch (13 mm) drive. Otherwise, use a ratchet and socket of the proper size on the tensioner pulley center bolt.
    • 5 Rotate the tensioner pulley away from the belt to release the belt tension.
    • 6 Pull the belt off of one of the pulleys and slowly release the tensioner pulley back into position. Do not let the tensioner pulley snap back or you may damage an internal component.
    • 7 Finish removing the serpentine belt from the rest of the pulleys and the engine compartment.
    Installing the New Serpentine Belt
    • 1 Match the old belt to the new one and make sure they are of the same length and configuration. It is normal for the new belt to be slightly shorter since the old one has been stretched through use.
    • 2 Route the new serpentine belt through all of the pulleys except the tensioner pulley. Use the diagram on the engine compartment or your notes, as a reference, to properly route the belt.
    • 3 Insert the large breaker bar into the square hole or the ratchet and socket into the tensioner pulley center bolt.
    • 4 Rotate the tensioner pulley in the same direction you did to release the belt tension.
    • 5 Slide the serpentine belt onto the tensioner pulley.
    • 6 Release the tensioner pulley back into position.
    • 7 Look at all the pulleys and make sure the serpentine belt is properly seated on each one. Otherwise, release the belt tension and adjust the belt.
    • 8 Connect the ground (black) battery cable using the wrench.

Thanx for diagram, where do i start on changing serp. belt on 1996 bonneville?


Crank the tensioner over so that you have some slack in the belt and pull the old one from one easily accessible pulley. Pull the belt off the pulley system and put the new one on following the diagram. Crank the tensioner again and use a screwdriver to pull the belt over the uppermost pulley. Release the tensioner and check belt tension.

How do I change the pulley on my 01 sante fe v6? I know it has an automatic tensioner but I don't know how to take the serp belt off to change the pulley.


Tell you what... No response, then I can't help. If you're talking about the accessory drive belt tensioner pully, there are two 12mm bolts which mount it to the engine. You'll need a 3/8's drive ratchet (or other 3/8's drive device) to release the tension so you can remove the accy drive belt to facilitate removal of the tensioner pully. Once you're remove the accy drive belt, remove the two (2) 12mm bolts holding the tensioner pully to the engine (make visual note of position/direction of the drive belt when you do this because you'll need to position the drive belt in the same orientation when you install a new auto-tensioner in place of the old one.).

hi, you should find a serp. belt routing diagram on the cross member that supports your radiator. if not- disconnect neg batt terminal for safety. you'll need a long breaker bar metric. as most, if not all fasteners on your ram are in metric. cant remember right size socket, but just go through your metric set and "eyeball"it. once you have the proper socket-detention the belt by pulling breaker bar clockwise. remove old belt. it maybe useful to take a picture of how your old belt is routed with a camera equipped cell phone (if it is still on) so that if you get into trouble, you can look at the picture as a reference point. new serpentine belt install--insert new belt over the cooling fan route under crank pulley-over fan pulley, around p/s pump pulley,up and around a/c comp pulley, under idler pulley, over alternator pulley and finally around tensioner pulley. pull breaker bar clockwise to slip belt past and onto the tensioner pulley. release tension on tensioner. be sure to check tensioner indexing marks located on the tensioner arm this is to make sure the new belt is installed properly. reconnect neg batt cable to terminal-remove any hand tools from engine bay, start engine and observe belt operation. hope this helps!
