the size is E14
T55. At least on my '91 Ranger....
hi the size you need is a T45 . i thing the T stands for torx
For my 1999 Sable it is a Torx 15mm. I got one from O'Reilly and this is what they claimed is the correct tool. I was able to loosing the bolt on the tensioner, but the torx socket was somewhat loose. Captainjack75040
what size torx bolt holds the rear parking brake housing on the 2005 chrysler pacifica
Torx #45
# 55
torx key t25
t-45 torx
on back side of block near oil filter it is a 17mm bolt or a torx bolt look like a star almost don't know size of torx bolt
the tensioner has a torx head bolt that comes in from the backside of it, you need to remove the belt and access the torx head bolt from underneath.... it is easier to have someone hold the new tensioner in place while you start the bolt back in and tighten it
I believe it to be a T-55 torx.
The correct size Torx bit is a T-55.
