I have a 2004 C70. I would like to replace the serpetine belt and tensioner soon.
I have a gates belt, and a dayco tensioner.
The problem is, I need to find out the size of the TORX bit to fit the hole to release tension to remove/install tyhe belt.
I bought the square bit tool, but this tensioner has a big TORX. The largest TORX I have is a T-50, and that is too small.
The bit I need is almost twice as large.
Anyone here know the size of that bit?

 

Just watched a youTube vid and it mentioned a T-60. I just ordered a t-55 and t-60. If they fit, I'll be back.

 

If you take (or hit) off that black cover on the pulley itself there is a 14mm that you can use instead of the torx.

 

hmmm, I'll have to lok at that. Thanks.

 

I pulled the cover and it is a smaller TORX on the pully. Oh well.

 

Yeah sorry I forgot about that some of them have them some dont. Without seeing the tensioner I wouldn't be able to tell you.
