did the belt fall off, not told , the story.

all have tensioner that must be retracked
2 kinds, fixed bolt kind
or, the spring loaded kind and to be frank we make sure is kind is not bad first. if there at 19 years old.
called the main front drive belt system. (not cams)
I am not answering for all 7 sorry.
all we do is look at it. see what tensioner is there,
if spring type we retract it with a beaker bar socket drive. per the manual told in services manuals
if not spring type out comes my tension tool and per spec, do that.

Question translated into written English.
Question edited for full year make model as required.
Question moved to to 2006 Lexus GS300 category

2005, 2006, 2007 are the generation years that remain the same. You could also try cleaning with a light application of acrylic polish.

just loosen the alternator on its track then pull it so that the belt is loose and remove the belt and replace then tighten again

On this website, you find fuse box diagram and description for Lexus GS300 (2006)

You shouldn't need to loosen the tensioner itself. To release pressure on the belt tensioner, rotate the belt (or tensioner pulley if the belt is no longer installed) CLOCKWISE. This will release the tension to either remove the old belt or install a new one. Once installed, the belt tensioner will automatically take up the slack.

i have lexus gs300 2005 i get problm i cant find fues for lihgter if any one can heelp me thank for evry one

It could literally be anything. It's telling you to go to an auto electrician and have the code read. Alternatively you can try buying an OBDII tool and read it yourself.

i would replace the timing belt flush the tranny change the oil check and all ball joints bearings all alignement parts for wear and change the oil adjust the valve timing check the serpentine belts replace them recharge the freon and flush the cooling system flush the power steering and flush the brake fluid that should be it hope this helps

the tensioner is generally spring loaded. check that you have the belt correctly routed. then you may need to attach a socket/rachet to the center bolt of the tensioner to move it enough to slip the belt on. if it moves freely it likely needs to be replaced as well.
