Greetings all,
First time posting here as I simultaneously pull out my remaining strands of hair. I need to change the drive belts on my wife's 1999 300M. I have a Haynes manual for the Concord/Intrepid/LHS/300M but when it come to anything under the hood of a 300M it's all but useless. None of the guidance or illustrations match anything in the manual. Any tips on where/how to start? Specifically with the flat serpinteen since it has to come off first. It doesn't appear to have an idler pulley...if it's in there I can't find it. I don't see any kind of adjustment mechanism, but then again it's so doggone packed under there I just may not be looking in the right place. Any tips on how to do this operation? I'm actually fairly mechanically inclined but the 300M is a real bugger to work on. Thanks in advance.

Remove the upper rad support 13s 10s and trim clips then u can get to the belts both have screw adjusting bolts and both need the nut in front of the pulley looses first b4 they will move with the srew.

 

Thanks Chrysler Tech! That's exactly what I needed to know. You're awesome!
