i need to replace the seals in my power steering pump and when i started to push back the belt tensioner I felt the bolt turn i have pushed it back a couple of times and never noticed the bolt turning any. i definitely don't want to break the bolt off and im afraid if i push enough to slip the belt off then i would never get it back on. its like the spring in the tensioner is not budging. anyway what suggestions if any could someone provide
Thanks

 

Are you sure you're pushing on the right bolt?

Which bolt are you wrenching on found on the link below?

Alternator Bracket for 2006 Acura TL SEDAN | Acura OEM Parts

#7
OR
#8?

 

i actually thought i had to be on the wrong bolt at first so i doubled checked. i decided to go old school so i didn't snap the bolt off and used a pry bar against the pulley vs the breaker bar on the nut to get the belt off. I know not preferred method....i have taken the serpentine off many times and i have never had the bolt turn vs the spring tension as it should. bad tensioner maybe?

 

As you said, perhaps it is simply bad and for whatever reason that bolt is loose. Is it also possible that your socket was the issue? If i recall correctly, that's a 14mm? Using the right socket and it had a good fit, and it wasn't shearing it off?

 

I am going to double check the socket tomorrow. it is a 14 but it could have been a worn out 14. I am going to look at it. I need to check the torque specs who knows maybe it was loose and i need to confirm if i do sheer it off if it would just be replacing the tension assembly. I have never had a tensioner bolt be loose and i don't know what the "normal" signs of failure are on the tensioner. I need to do some reading on it and have not had the chance
Thanks

OP, just curious, if you are using bolt #7 on the linked diagram I provided, I believe that bolt is 'left-hand thread'. Therefore, if you use a long 14mm wrench, standing in front of the car, and pushing the tensioner forward with said wrench in an attempt to remove the pulley drive belt, you should be tightening the left hand threaded bolt?

 

exactly what i was getting at, it indeed is left hand threaded so there is no way it could have loosened up if on the right bolt

 

If you were to shear off the correct bolt (bolt #7 in Zeta's link), I think you just need a new #7 bolt and #10 nut. No need for new assembly.

If you were to shear off the wrong bolt (bolt #8 in Zeta's link), the following link might help.

I'm hoping you just used a worn 12 point socket or the bolt head on #7 itself is worn. Try a good 6 point socket.
