jeep crd tools
Ok, I just completed my wifes liberty. I'm a certified aircraft, marine, motorcycle and automechanic.
The tensioner tool for the timing belt, 2 - pins that fit inside the holes, 7 mm box wrench one one against the other whala!
Drill bits work fine for the alignment tool for the cams with clear nylon tubing slid on over to fill the gap of the valve covers. (when you remove the cam pulleys you'll see the two drive slots are facing each other) clean the entire area with brake cleaner.
Cam pulleys can be removed and tightened quickly and easily. You get the correct bolts to fit the three holes for each. They will need to be long enough for one two nuts each. strap steel to form a triangle on each pulley, and one cross rod top from one pulley to bottom of the other pulley (cancelling the rotation). Reverse when tightening. Walk in the park. So all three special tools were nothing but made at the local hardware. This engine is one very easy and fun to work on.
Now, at 90 thousand miles I found replace all idler wheels, the squealing squirl is usually the fan bearing support. At your local Jeep Dealer have them look under the engine block. Replace the lower radiator hose, turbo tubes as well. Remember your in here do it all and you know you can run another 90k miles.
