In this video, it is mentioned that the 14 mm bolt should be torqued to 31 ft lbs. It is between the values for class 4.6 for lubricated and zinc plated bolts. It is kind of surprising. I was expecting a plain & dry type of bolt.

 

Toyota provides universal bolt torques for any bolt you want. However, some bolts, especially ones inside the engine, often have their own special tightening requirements that have to be followed.
Also, sometimes a similar bolt will have a different torque depending on where it's going and so on, so it is still best to follow recommended specs at least until you've turned enough bolts to get a good feel for it.

To OP: this table is also available in the factory manual in Service Specifications - Maintenance chapter (the left and right of the image are two separate pages). There is also a page for nut strength identification that you then use with the second page of bolts torque. The same chapter has most of the torques in the manual listed in one place so it is a quick GOTO place if you know what you're looking for. It also includes all kind of specs like clearances, diameters, temps, electrical voltage, resistance, etc.

 

Most of our car bolts already have a prescribed torque in the manual. Just look for it in the diagram or in the "install" section of the procedure. The factory manuals are available online as PDF's if you search well.


For the ones w/o a specific torque you can just do it by hand if you have enough experience or use the general chart posted.


I advise you NOT to use a general table unless the manual does not have a spec for that bolt.

 

Hi I almost died of googling after reading your comment. But I just cannot find a PDF download. So please PM me if you know a link. Thanks a bunch.

 

Cannot post links directly, against forum rules. BUT... if you happen to google "99 Camry FSM" and click on about the 4th link that comes up (for cardiagn site), a giant teddy bear will jump out of your screen and hug you mercilessly.

 

Is there anyway to download the fsm? This site is quite tricky. I clicked several buttons. It seems that this website wants to add all sorts of software on my computer but is not willing to give me the content. So I must read it from this website?

BTW the pulley bolt uses 14 mm socket but the bolt shank is probably 10-12 mm don’t remember.

Anyway interesting the 31 lb/ft never thought that was indeed kinda low. But as mentioned what the book specified!
