Default How to remove entire belt tensioner

I need some type of step by step instructions on how to remove this belt tensioner without removing any of the intake components i.e. Upper plenum, gaskets, and manifold... I just got the leak fixed by an ase technician and i would hate to go behind him and take all that apart just to swap the belt tensioner.... Is there any simple way to remove this belt tensioner??? I already removed the alternator.. How many bolts must i remove to get this thing off????

Well, coolant flows through the tensioner assembly, so it'* a bit tricky. That'* all I can tell you.

I find it really easy.

Disconnect your battery
Pull the battery cable and connector off the alt.
Remove alt by the three bolts on the front and one on the rear (pic for ref on bottom bolt)

Then after you drain about 1/2-3/4 of a gallon of coolant you are ready to remove the tensioner/alt bracket by pulling the three bolts. One is not visible near the back of the motor. (Pic for ref, your tensioner is nearly the same)

Nothing tricky at all. 5-6 bolts and wiggle it nicely. There is a plastic coolant elbow going into the LIM. There is another metal elbow (part of the tensioner) going into the timing cover. If you pry hard you can crack the timing cover. Wiggling will get it..time and patience will be the winner.

Give it a rinse cycle when you put it back together. It'* not something the rest of us haven't done before.
