Replace tension pulley for serpentine belt on 1998 Galant with 4G63 engine with AC.

Hi.
The tension pulley is making a squealing sound, so I need to replace it.
I have loosened the tension pulley but I can not get it out because of the attached bolt in the pulley. I took out the tightening screw completely.

How can I get out the old pulley and replace it?

After removing the nut, the pulley should come off. If it is stuck, a little tapping on it should turn it loose.

Hi and thanks for the reply.

If you look at the link, you see there is a bolt attached to the pulley. This is for a 2,4 engine, but it looks similar.

After the nut is taken off and the belt is loose, I still can not get this pulley out of the track where it is. This is due to the bolt being longer than the space i can use to pull it out towards the fender. The pulley is loose and easy to move around, just not possible to get it out.

I have googled this a lot and it seems there might be another nut in the backside of the pulley(between the fender and the back of the pulley). It is extremely tight so I am unsure if it is even possible to get to this nut.

Can this be the way to remove the pulley?

I have been able to spray some wd40 into the "bearings" of the pulley when it was loose and that silenced the noise for now. This is however just a quick-fix I am afraid of.

You are right about the WD40 being a temporary fix.

The bolt goes behind the pulley and is attached to a bracket that is used by the adjusting bolt to adjust the tension. The space is tight but if you release the adjusting bolt further, you might be able to get enough space to get the bearing out, though the crank pulley might get in the way.

If all fails, the other way to gain addidtional working space is to remove the engine mount and raise or lower the engine.
