Auxiliar belt tensioner stuck?

freespaña · Nov 30, 2020

Hi friends.
I can't move the alternator auxiliary belt tensioner. It must be moved counterclockwise to loosen but no matter how hard I do it is impossible. Is it stuck? Any idea how to loosen it even if I have to change the tensioner? Any fantastic idea to dissamble the tensioner without dissambling half motor?

Any idea will be well received.
Thanks for your time and help.

The tensioner nut collet /bolt is anticlockwise to tighten, so to remove therefore must be clockwise, you also may need to get an open ended spanner behind to hold the bolt head, hopefully these photos below will give you an insight.

A ground down spanner helps to get into the tight gap.

Even though this is shown on an engine off the car it can be done in situ.

Do not lose the spacer.

Hello. Fantastic and graphic explanation. Thanks for your time. If I need to change the pulley now I know how do it.
Maybe I didn't say clearly what do I want to do: move the tensioner pulley to loosen the belt and change it.

Thanks.

Its the same principle you can try putting a spanner behind first to tighten the nut up, so the tensioner will go further back, also an aviation spanner gives you more leverage and arch in turning.

Thank you very much.
Tomorrow I'll try to push firmly anticlockwise to move the tensioner and loose the belt.

Good fit ring spanner is essential. Jam it to stop it slipping off with a piece of wood against the chassis rail.
15/16 inch AF is best fit. 24mm will do.

Ok. Thank you very much.
I had a problem because the spanner was released.
I'm grateful for your help.

Aviation spanner is good it give you more leverage, also as above you can jam it with a piece of wood, if the nut starts to turn loosen it clockwise add some locktite or super glue onto the thread then tighten it back up leave to set, and should be good to go.

My belt was or looked to be in good condition, it was the compressor belt that was ready for a change so check that as well.

Hi. I checked the compressor belt and it's like your belt. I'll change both. Good idea to mark the lower tensionner.
I had seen a leak from thermostat. I'll change it too.

Than you very much. Your help is greatly appreciate.

Belt out!!! thanks to your ideas.
Any fantastic idea to dissamble the tensioner without dissambling half motor?

After lots of messing with regular open ended & standard angled ring spanners, I bought these from amazon. Now doing the tensioner & belt is really easy. Amazon product

Hi. Thanks for your imput.
Finally I have no choice to remove it dissambling compressor and alternator.
