Hi Everyone,

I own a 2003 ES 300 with about 69k-70k miles on it. I was told by the dealer to start "thinking about" replacing the timing belt. They want a little over $1000 to do the job (includes water pump and labor). I'll probably get it done else where, but my main question is to owners of this particular vehicle or even the 02 ES 300 is: when did you replace the timing belt? I've read some people changed it at 60k, some changed it at 120k, and some people had it snap on the side of the highway around 100k. I always thought 90k miles replace it, but I also hear 90k or 9 years, which ever comes first. Any info would be appreciated as this is an expensive job and would be a lot more expensive if the timing belt breaks! Thanks in advance!

Read your owner's manual. It specifies the change interval.

The problem is that one guy will say yes and the other guy will say no. You are taking the chance with your life....

I've never heard of an original factory 1mz-fe timing belt snapping at 100k. They are robust and proven designs incorporated in most Japanese engines, not just Toyota.

They are supposed to be 90k mi or 7(?) years. I personally believe the mileage is more indicative of wear on it than time, but type of use matters a lot. Extensive city driving vs. extensive highway miles is a world of difference. One can be worn at 90k, the other go 150k or more. Some people who drive highway miles might go 120 miles and be fine with the risk vs. the stated interval. It is, after all, a "one size fits all" diagnosis in a world that just isn't that way.

As a note, over several years, I have had 2 dealership timing belt jobs go bad during the next service interval because of sloppy work. One Audi, one Acura. Now I do my own so I know they are correct. I'd plan on finding the best independent Japanese/Toyota shop in your area and have them do it if you do not have the skills, time, or desire.

Hi Brandon,

I've been the proud owner of a 2003 ES300 for about six weeks. My car had a lot of service records indicating regular oil changes and filter replacements, etc., but the timing belt had hot bee changed. I ahad the timing belt and water pump done together and also the valve covers were leaking a little so I got that done also. I went to a family owned garage in Fort Myers that had been in business since 1969 and warranties all their work for 1 year. They did all the work for $944 and I feel like I got a fair deal and good work. IEven with all the good care my car had, the previous owners avoided changing the timing belt at 6 years. Make sure you feel good about the people working on your car and ask them what brand parts they use, and how much experience they have changing timing belts on Toyotas and Lexus.

Good luck,
