Default idle pulley + belt tensioner

my idler pulley wiggles ever so slightly, should i replace it?

also is there a way to test your belt tensioner, does it require a certain amount of torque for it to begin loosining tension. im sure its normal but when under the hood, in park, the tensioner gives a lil bit when given gas, which i can see as normal, since its given a load. it definitely doesnt make the belt slip.

Default RE: idle pulley + belt tensioner

Idler pulleys will wiggle a little. As long as it is not making any noise or seizing up, it's fine. It is absolutely normal for the belt tensioner to give and take a little under acceleration.
