I just found the motherlode of Toyota TSBs this morning. One of which is a full parts list for installing an engine oil cooler on a 2WD or 4WD 3VZ-E that didn't come equipped with one from the factory. It's got all the part numbers, torque specs, and even some schematics of the components.

The rest of the install procedures are covered in the FSM for those that are interested.

EDIT: You'll find many of the part numbers listed in the TSB have been replaced/superseded in the time since it was published(3-10-91). This doesn't present any issues as far as new parts working with old parts. In all instances of such mismatches pertaining to parts needed for these installations you can use either the part with the original part number listed(if said part is still available), or the part with the new part number that replaces/supersedes it. AFAIK, that should be the case anyways(can't imagine why not, since generally it is).

Some OEM parts suppliers will give you the new part number(typically "Replaced by:xxxxx-xxxxx", occasionally "Superseded by:xxxxx-xxxxx") when attempting to purchase a replaced/superseded part, while some won't. Some when given the original part number will give you back the replacement/superseding part number for the part you're requesting without making any note of it. You just have to take it on good faith that, despite the part number being different, said part will still work for your application.

 

thank you for sharing!

 

MH, I was wondering when you would find all those TSBs there.... That has been a favorite site of mine for info over the past several years.

 

Indeed, 'tis true, 'tis true. Might have never found them without your help. All thanks should really go to you on these.

So thank you very much rworegon!
