For a 1997 Lexus ES300, what is the direction to turn the wrench when I want to loosen the bolts for removing the motor mount? The one I'm trying to replace is the one on top that is very accessible and secured by 2 bolts, one to engine and another to frame (torque mount).

My research on other model years:

From a forum thread for the 1998 model, one answer claims its 'lefty loosey', aka counter-clockwise? Similarly the tutorial video of a motor mount replacement for a 2003 model also shows both bolts being turned counter-clockwise.

One of the forum comments also said it should be 'threaded against the direction of rotation', if so perhaps I can infer that '97 is also counter-clockwise rotation to loosen.

It is a good assumption to think all bolts are lefty-loosey or counter-clockwise to loosen them (considered right hand threads). Left hand threaded fasteners used to be a lot more prevalent, but hardly used for automotive purposes anymore. There are exceptions, but generally they are very hard to find.

  • I thought a left-hand thread is a rare thing, like those in bicycle pedals, or holding the chuck in place on a reversible electric hand drill. Right-hand threaded fasteners are in the majority, yes?

  • @fred_dot_u - You may be right in that I mixed up terms ... because right hand threads are the direction you tighten them, not loosen them ... I'll correct my answer and thanks for pointing that out.

  • I have removed several motor mounts and never found a left hand thread .
