i have a 97 es300 , i replaced the power steering belt, by going through the wheel well. i took a chance by lossening up a visible screw, it worked and slid relieving the tension.. i replaced yhe belt but cant get that screw to move again! was that the power steering thingy i moved, i pressed and pulled at everything. should i just tighten the screw "as is"? the belt seems tight, with little slack. Quick responses will be greatly appeciated, car is still apart, and i have curch tomorrow, the work monday, LOL. E-Z fix gone wrong! thanx in advance
