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. Feb 27, 2019 at 21:27
  • I have removed several motor mounts and never found a left hand thread . Feb 27, 2019 at 21:34
