I know everyone hates newbie questions...lol and I'm sorry but I could not find answers to these questions. So thank you in advance for your help!

1. I just got my GX and of course did not know about the timing belt needing replacement at 90k (I'm at 86) - My plan is ti run it till about 120-130k before replacing because it's a huge chunk of change. Has any one had their belt fail at these mileages?

2. why in the world are there no aftermarket repair manuals??? Can I use a sequoia manual?

3. Would there be any benefit is I change my plugs to Bosh Platinum +4's?

Again thanks guys I really enjoy this site!

Cheers

I agree with above on everything but firmly believe 100-110k on the timing belt would be fine. I have spoken to multiple mechanics that say at 90k they have never seen a timing belt that they fely needed replacement. Its more of an insurance thing and Lexus figures 90k is a good starting point.

another factor could possibly play a role is that your GX is 7yrs old.........eventhough its got only 86K miles on it. That's your call.

I am sure any plug would work, copper, platinum etc, the advantage to the stock plugs is they are iridium...they last and perform better much longer than the others.

Do not risk with the Timing Belt. Change it by 100k miles. A good independent shop will not charge you a fortune. Make sure they know Toyota engines.

2. why in the world are there no aftermarket repair manuals??? Can I use a sequoia manual?

There are many good paper or CD/digital repair manuals online/Ebay for the Lexus GX or the 4Runner. Get one of them. I bought a repair manual on a CD for $50-60. It's very detailed. If you are planning to work on your car, do not be cheap and get the right tools & books. It will save you lots of $$$ in the long run. Also, for $20 or less, you can find a 4Runner/GX470 Haynes manual. It is pretty basic, but has some great information in it.

3. Would there be any benefit is I change my plugs to Bosh Platinum +4's?

I personally never had good experience with Bosch spark plugs. Get Denso or NGK iridium plugs (or at least Platinum). Check online auto parts stores. They have good deals on them.

I have owned 3 lexus's and learned it's not necessary to do timing belt and water pump til 110 or 120 K miles. My mechanics say that most of the time they are in great shape when they're replaced at 90K. Also, shop online for Toyota parts and you'll save a ton. Then take to a trusted independent mechanic.

NGK or Denso is all I'll ever use on any japanese brand.
