i am really tired of everyone stating that it is recommended to change the timing belt of a 1990 ls400 every 90,000 or 100,000 miles...... i own one and it does not say it anywhere. i have the original owners manual and the maintenance manual. it is not in there. based on my driving methods i would fall into maintenance schedule b. it is not even listed on the schedule. where is everyone getting there information..... if is recommended or needed it should be in the book..... not told to you by a dealer.
can anyone show me where in writing it is. use a manual that a normal owner would have.
