tensioner wont hold tension, need help please

[green-lantern]

yes, its compressing when i start the car.

and ill say it again, this is NOT a shitty tensioner from advance, both of my tensioners are from 3sx.

Honestly just because 3sx sells them doesn't mean they are good. They will give people the option to buy a cheap aftermarket one because some want that option. When it comes to 60-120k parts I'll only use stock mitsu. Did you buy the stock one from them or did you get the aftermarket one from them?


Edit: Like this?

It looks like you have it tensioned right, looks like the pulley was adjusted the right way. Very weird! I don't want you to risk harm to your engine but I'd love to see a vid of this happening.

Have you let the engine sit for a few at TDC before you pulled the pin? I wonder if you got it too tight.

I have run into bad out of the bag OEM tensioners. It happens.
How many have tried this:
Solid Tensioner

The problem with the solid tensioner is that you have to keep an eye on the belt and adjust the tension so often as the belt slacks from age. Which can be a pain considering everything that has to be removed just to get to it!!! That is the purpose of the stock tensioner, so you don't have to keep adjusting it. If you don't mind having to keep and eye on the belt tension it would be a good way to go. Personally if I will most likely be going with a solid one at some point as I am always inside the engine and have something apart...LOL

Best bet, send it back to 3SX and have them send you a new one. it's getting to the point with OEM tensioners that they almost need to be tested out before they get shipped as more and more seem to be failing right out of the box.

Can you cut a hole in the timing cover and adjust it without pulling everything apart?

[DrGonzo]

I wondered that too but I thing the pulley and belts might be in the way. I'd also be worried about getting crap into the lower end with the hole cut there

Anyone got a pic of the lower end with everything installed besides the cover??

[n2nsanity]

i have a pic of my 3.5 before i put it in
its on my blog

tensioner pulley looks right to me, can't see the plunger in this pic tho
this is prob a stupid ? as you've done this more times than me
but did you put the pin back in before removing the old tensioner?
i think it's bad if it ever extends all the way out and may not hold pressure properly after
also, did you replace the belt? and with which one?

[Alex3000gt]

How are you tensioning the center of the pulley? Are you using a torque wrench with the proper spec? Or are you just pushing it until it "looks about right"?

The second option could potentially cause a hydraulic tensioner failure.

Im not sure I fully understand what you are saying. You tension the belt by turning the concentric pulley until the proper tension is put on the Hydraulic tensioner (So the pin slides in and out easily). It doesn't matter what you torque you put on the bolt going through the concentric pulley as long as the proper tension on the belt is achieved.

Maybe I misunderstood and you can explain more clearly.
