use the 14MM wrench heavily "belt tensioner" turn the drive socket haha i call it the "wrench" right to tighten up the bolt than the pulley should lower down for the belt to be removed

follow the diagram starting from top sides then to the bottom and where the last bottom pulley cant be tuck in, you would have to use that 14MM Drive socket wrench, where the bolt was to loosen it up than tuck it in

It's very nice to see the pictures step by step.
I need to do this this week.
I haven't not any work on the car except for filter changes, but this looks simple enough or is it that I'm underestimating this job?

How about putting the new belt on? How much to I tighten up the bolt?
I have seen a post about over tightening the belt or something like that.
Thanks.

Update: https://www.clublexus.com/forums/sho...d.php?t=121862 says to turn the bolt counterclockwise to loosen the belt. I think your description says to turn clockwise.
Which way is correct?

Updated my post:

From what I can see the 300 is Clockwise and the 430/400 is Counter Clockwise.
