Where are the tension springs located? - Cars & Trucks

no car told , no possible answer
nor where inside car this part exists (location) not told

NO engine told of 7, and is an engine question wow hard. that.

the service manual covers that.

did the belt fall off, not told , the story.

all have tensioner that must be retracked
2 kinds, fixed bolt kind
or, the spring loaded kind and to be frank we make sure is kind is not bad first. if there at 19 years old.
called the main front drive belt system. (not cams)
I am not answering for all 7 sorry.
all we do is look at it. see what tensioner is there,
if spring type we retract it with a beaker bar socket drive. per the manual told in services manuals
if not spring type out comes my tension tool and per spec, do that.

governors always stop in the full throttle position
when the engine starts the governor action is to move to the idle position against spring tension
the higher tension the higher the rpms
moving the throttle lever increases the spring tension on the governor lever an so the rpms increase
from what you say there is something wrong with the governor/ spring set up
from your photo the system may be reversed and the spring pulls to idle in which case the throttle will decrease the spring tension for higher rpm
which ever way check where the spring is located

1. Rotate the drive belt tensioner clockwise and remove the drive belt.

Hope this helps

there is a tensioner for the serpentine belt, it is spring loaded so it adjusts by itself. if the belt is loose then the spring in the tensioner has gone south. you need a new tensioner, about 50 bucks but replacing it is beyond normal owner servicing. there are many videos of folks replacing tensioners on youtube. note the tools they have, and most videos are shot from under a lift. if you have all those on hand, then you would not have asked the question. buy the part and take it to a repair shop.

DEALER ONLY (aftermarket gives you wrong tension)

Hello. Yes, your tensioner is spring loaded, BUT the spring is encased, or should be depending on the location of the break. The new one will not have any tension that will affect the installation process. You can see this on the new part. Just re-route the serpentine belt correctly, you shouldn't have any problems, you sound like you have some experience. remember to use thread-lock.

to get good leverage use a serpentine belt removal tool. the bolt should be on the base.

1. REMOVAL
   AIR CONDITIONING BELT
   
   NOTE: The A/C drive belt self tensioner is NOT a dynamic tensioner. After adjustment the tensioner bracket bolts are tightened. The torsion spring is no longer responsible for tensioning the A/C belt. The torsion spring is only used for initial belt tensioning.
   1. Remove generator/power steering belt to gain access to A/C belt. Refer to GENERATOR/POWER STEERING BELT for procedure.
   
   
   1. Loosen BUT DO NOT REMOVE tensioner locking bolt and pivot bolt (Fig. 2).
   2. Insert 1/2" drive breaker bar into square opening on belt tensioner. Rotate tensioner counterclockwise until belt can be removed from pulleys (Fig. 2).
   3. Slowly rotate tensioner clockwise to relieve spring load.
   CLEANING
   Clean all foreign debris from belt pulley grooves. The belt pulleys must be free of oil, grease, and coolants before installing the drive belt.
   
   INSPECTION
   Belt replacement under any or all of the following conditions is required:
   
   • Excessive wear
   • Frayed cords
   • Severe glazing

• Poly-V Belt system may develop minor cracks across the ribbed side (due to reverse bending). These minor cracks are considered normal and acceptable. Parallel cracks are not (Fig. 3).
  
  NOTE: Do not use any type of belt dressing or restorer on Poly-V Belts. INSTALLATION
  
  AIR CONDITIONING BELT - NEW
  
  WARNING: DO NOT REMOVE A/C BELT TENSIONER LOCKING BOLT WITHOUT FIRST HOLDING THE TENSIONER WITH A 1/2" DRIVE BREAKER BAR, AS PERSONAL INJURY COULD RESULT.

NOTE: Verify that torsion spring position is in the new belt position before installing a NEW belt (Fig. 4). If torsion spring is not in the new belt position, follow steps 1-7 to change the tensioner spring from the USED belt position to the NEW belt position.

1. Insert a 1/2" drive breaker bar into the square opening on the tensioner. Hold counterclockwise pressure on tensioner while removing the locking bolt (Fig. 2).
2. Carefully release spring load of the torsion spring on the tensioner.
3. Remove pivot bolt, tensioner, and spring from front timing cover.
4. Insert spring arm into the NEW belt position on the tensioner (Fig. 4).
5. Install torsion spring, tensioner, and pivot bolt.
6. Install pivot bolt. Tighten only finger tight, at this time.
7. Using a 1/2" drive breaker bar, apply counterclockwise pressure until locking bolt can be installed.
   1. Install the NEW belt by rotating the tensioner counterclockwise until the NEW belt can be installed on pulleys. See (Fig. 5) for belt routing.
   2. Release tensioner and remove breaker bar. Belt is automatically adjusted with the tensioner's torsion spring.
   3. Tighten tensioner locking bolt and pivot bolt to 28 Nm (250 in. lbs.) (Fig. 2).
   4. Install generator/power steering belt.
   AIR CONDITIONING BELT - USED
   
   NOTE: A "used belt" is considered having more than 500 miles of service use. NOTE: Perform steps 1-7 to change the tensioner spring from the NEW belt position, to the USED belt position.
   1. Insert a 1/2" drive breaker bar into the square opening on tensioner. Hold counterclockwise pressure on tensioner, while removing tensioner locking bolt (Fig. 2).
   2. Carefully release the tension of spring on tensioner.
   3. Remove pivot bolt, tensioner, and spring from front cover.
   4. Insert spring into the USED belt position on tensioner bracket (Fig. 4).
   5. Install spring, tensioner bracket, and pivot bolt.
   6. Install pivot bolt. Tighten only finger tight, at this time.
   7. Using a 1/2" drive breaker bar, apply counterclockwise pressure until locking bolt can be installed.
   8. Install the USED belt by rotating tensioner counterclockwise until belt can be installed on pulleys. See (Fig. 5) for belt routing.
   9. Release tensioner and remove breaker bar. Belt is automatically adjusted with the tensioner's torsion spring.
   10. Tighten tensioner locking bolt and pivot bolt to 28 Nm (250 in. lbs.) (Fig. 2).
   11. Install generator/power steering belt.
