bouncing fan belts

[Kenneth Cole]

Good day
Question, is it normal for the fan belts to bounce up and down when she is running? I have adjusted the tension on them with no change.

Thanks
Ken

Mine bounce and I have them tensioned correctly and they are matched. I was thinking of making another tensioner to cut that down but it hasn't affected me enough yet.

Yes, bouncing on V-belts is perfectly normal, within reason.
If it's bouncing enough that it's coming into contact with other things like radiator hoses, or you can hear squealing from slippage, then it's too loose.

Yep, normal like they said, I am SOO happy not to deal with them anymore, gets even worse when you are running a 200A....

I just posted this exact question perhaps three weeks ago. Exact same answer.

Bouncing at idle is 100% normal but if it doesn't settle out when the engine RPM comes up somethings wrong.

They are bouncing because they are happy.
