Post Timing Repair Project - Bolt Torque Specs

Hey everyone - I'm in the middle of the timing belt / water pump replacement project of the gf's '02 PT. While getting ready to reassemble everything, I found myself searching dozens of pages searching for the correct bolt torque specifications. As I went along, I compiled a list of many of the bolt torques that you may find helpful during the project. Be sure to pay attention to the units! Ft-lbs does not equal in-pounds!

Feel free to add any that I may have missed, but keep in mind this is intended primarily for the timing belt and water pump replacement project.

Bolt / Qty / Torque / Units
ac line (above pass. strut mount) 2ea, 40 ft-lbs
ac compressor mounting bolts 4ea, 21 ft-lbs
camshaft sprocket bolt 2ea, 85 ft-lbs
crank pulley bolt 1ea, 100 ft-lbs
engine mounting bolt (right T55) 1ea, 87 ft-lbs
engine mounting plate bolts 3ea, 45 ft-lbs
power steering bolt 3ea, 250 in-lbs
radiator and shroud screw 6ea, 55 in-lbs
timing belt cover bolts 7ea, 50 in-lbs
timing belt idler pulley 1ea, 45 ft-lbs
timing belt tensioner lock bolt 1ea, 220 in-lbs
water pump bolts 4ea, 100 in-lbs
wheel lug nuts 5ea, 100 ft-lbs

I would also like to point out that this is for the second (2nd) revision of the timing belt tensioner.

For those who may be searching for it (as I did), to tighten the tensioner, loosen the tensioner lock nut, place a 1/4" drive ratchet in the face plate square and rotate the tensioner counter clockwise until the alignment tab lines up with the spring retainer, then tighten the center bolt.

do the bearing on the idler and tensioner require a pre load (example 45 ft lbs and back off 1/4 turn)

no. i believe most don't even torque those to begin with. i didn't. i've got 60k on my timing belt change with no issues. hell the only thing i torqued when i did it was the lug nuts. going on 50k now since i did the belt with no issues. i'm at 267k miles.

a certified mechanic may disagree with my method, but IMO just using common sense is good enough for most of those bolts. whoever wrote that must have been using a chiltons(ie: taking off too many parts due to bad instructions). the radiator shroud screws are listed, but those shouldn't even need to come off. AC line torque? LOL

Take pic of final belt line up. Comes in handy in cases were you run into a snag. Could save you a bunch of time. Any question about it, post them up for review before you close it.
