Easy one - fastener specs
Thanks for your help - Ive decided to ord the factory replacement parts -
Idler Pulley - This is the pulley on the alternator side of the Water pump - it seems that the idler pulley has an integral threaded stud - not a separate bolt like i thought
Tensioner pulley - The tensioner pulley "screw" has a special retaining washer ....
......so Im safer with the Mopar parts.
If Im wrong on the idler pulley please let me know - but the parts manual has no listing for an "idler pulley bolt"
