You can get the puller at your local AdvanceAuto or what not on rental.....its specifically has the set-up for the Chrysler 2.7,3.2,3.5 with out having to pull the radiator...this will simplify things. Just have to pull the fans...top radiator hose and 1 trans line on top.
Save time and rent it. Her is a pic.
BEFORE you remove the belt or tensioner turn the crank till you line the pointers on the crank together and the line on the cam gears line up between the dots on the covers..lock them as follows
Just lock the cams in place before you remove the belt..here is a poor mans version.....Remove the cover bolt behind the cam gear... use a longer bolt and a piece of tubing/pipe or an old piston pin like i did. you can adjust it up snug against the gear and then tighten it down...simple.....( I saw this from TFC on a search before I did my first one..what a little trick)
Install the belt counterclockwise ..crank to right side cam gear under waterpump to left cam gear and under tensioner pulley. (as looking from front of vehicle)
You can get a quality timing kit from Gates...TCK295. Includes the Pulley assembly with the belt.
The factory belts were made by Gates.
I have done 2 of these in the last few months..one on a 2000 LHS and just yesterday for my 2000 R/T.
It will take you the afternoon or better your first time.
Its pretty simple....
You need the puller....
few metric sockets...7,8,10,13,15,18 mm
standard screw driver
bucket to catch anti-freeze
vise or press pre-set the hydr tensioner..and a small allenwrench to use for a pin.
