Hey,
Last week i inspected mytensioner and it was in pretty bad condition (76k miles)

This diy to remove the fan is it accurate? I need to remove it because the acces is bad!

To remove and replace the tensioner i looked at the follow diy

I didnt receive yet the new tensioner so im not sure if i need the torx bit in order to remove the tensioner.

Any advices are welcome

You will need Torx to remove the tensioner. Removing the electric fan takes 2 min and gives you enough room to get your arm in front of the engine to do anything you need so def take it out. I am not sure what size torx you need but you will need a 1/2" ratchet to release the tensioner from the belt.

Do i need also the torx next to the specified by the arrow?

Yes that is the one to release the tensioner from the belt and its a large one that you will need a 1/2" ratchet and T60 torx to release.

Check out the DIY guide it has many of the torque specs you are looking for. SNUG + 1/6 is always a good guide. I checked my Bentley and could only find the idler pulley to alternator torque at 80nm.

I did this job months ago and found the specs / torque applications in the
DIY guides.

Decide if you want to replace the belts as well while you are at it ......

pepsih · 10-19-2013, 09:22 AM

yes yes i will

JOB DONE!
It took me +/- 2 hours.
i think the tricky part was to remove the fan, i had to remove the cover from the bottom in order to acces one screw thats attached to the fan, and i needed help from my brother in law to put it back.

thanks everyone for your help
