Hello guys

I have little issues with belt. Running out from harmonic balancer I already change a new one. But last night I notice the belt running out from water pump than go down to balancer.
I really need help about that any suggestions will be nice

Thx
Ed

What do you mean running out? Walking off the pulleys?

If so something is loose or worn causing one of the pulleys to be out of alignment causing the belt to walk off.

If running out means how the belt is supposed to travel from pulley to pulley there should be a diagram under the hood.

Hi
Yes walking off the pulley where is the fan than from that pulley run out from the harmonic balancer

Thx

I marked that position where is moving all time

So far everything is good with heat and coolant is same level. Maybe is pulley done

Just a wild guess, but the marks on the smooth side of the belt look like you might have the belt routed wrongly. Looks like you have the smooth side running over some ribs. Maybe double-check the belt path.

Yes i know that ribs running out on harmonic balancer but reason is pulley on water pump where is the fan. I don’t know why running off from pulley

That has to be routed wrong. The more I look at it, something is off with the belt routing. Time to pull the belt and redo it to make sure it is correct. 4.6 or 5.4 w/wo AC??

edbc

Is 4.6l with A/c

Does it come completely off, or is it just off a rib or two? Your writing doesn't make much sense. No offense, it just needs some work.

Second guess - your water pump bearing is bad and the pulley is cocked, letting the belt "walk" off of the pulley.
