Are all the oem idlers the same, front and back set?

Here's why i ask, my 03 cobra engine is missing the factory idlers for the primary belt setup (not the SC belt).
If they are indeed all the same, the classifieds have plenty of factory idlers from people adding them for the SC belt for sale and i'll just pick up a few. If not, i have to goto ford and get the right ones.
I already have a set of RR idlers for the SC setup, but the engine was literally missing all but one.

they're different

6 rib vs 8 rib

thanks for the quick replay.
How many do i need?
Are the ones i need all the same as each other?
I only ask because all the ford diagrams are crap, half the time the pics and part numbers are of the wrong stuff.

you're welcome....good luck on your project!

1 = Belt idler pulley
2 = Belt idler pulley
3 = Belt idler pulley
4 = Power steering pulley
5 = Water pump pulley
6 = Crankshaft pulley
7 = Belt tensioner
8 = A/C pulley
9 = Drive belt

.

2 & 3 are grooved and 1 is smooth

tensioner probably has the same grooved idler, but I'm not sure

99% sure the tensioner is smooth. from the looks of the diagram the back of the belt would be running on it. back of belt contact side= smooth and front of belt=grooved

 

[JB]

you're right, it's late and I'm tired

nice to see someone pays attention to stuff I post :lol1:

Thanks guys.
At least when i goto ford today i have a clue what to tell them i need.

Ok, little info. I have the parts in hand, i just haven't fitted the belt yet.
#2 and #3 appear to be the same, go figure since #2 only can be purchased with the bracket (extra $85).
I'll know for sure on monday.

#1 (smooth) is near identical to a removed idler from the SC belt. The SC one is about 1/3 inch wider, but still appears that it would work.
But i have the real one now so i won't be using the SC idler.
