Ls400 Timing Belt

davepruce · December 15, 2003

Hi All

A while ago I saw somewhere (I hope it was here!!) a set of photos and a brilliant description of how to replace the timing belt on an LS400.

Like an idiot, I didnt print it/save it, and now I cant find it anywhere.

If somebody could point me to it, I will be very grateful.

Cheers

Dave

I have a picture of the exposed timing belt

from when I did mine,[1994 model] will e-mail to you if want! :)

That would be good, cheers royt.

How was the job, just difficult or VERY difficult?

What else did you replace at the same time, going by the list on the page at Lextreme, its gonna be EXPENSIVE.

need your e-mail address to send picture.

Not so much difficult as extremely slow,the amount

of dismantling you have to do to get to it is the worst part.

I did not need a puller for the crank pulley it was loose enough

to pull by hand.A conventional puller will do it if stuck, you

don't need a special one.

Do not forget to loosen the crank pulley nut before you start.

Get someone to help you and mark bolts etc. as you remove them,

theres a lot.

I just replaced the timing belt and the serpentine belt,[61000 miles]cannot remember

exactly how much as I got new front rotors at the same time,allow about £200 .

I've only done about 4 timing belts on other cars and I was daunted by the size of it all.

However if you take your time and check as you go along,[make notes and digital photos

if you have to] you,ll be OK ,allow a full day to do it.

It will not be scarey for me next time!!

I'm no mechanic, so at 65,000 miles, I decided to ask the dealer the cost of this. $900!!

I took it to a local trusted mechanic, who himself drives a LS 400, and he did the job expertly for $480.

mine's just being done by a non-lexus dealer, costing about 500 pounds, but that includes two tensioners and a new waterpump, in addition to the belt. having seen some pictures of the job, i thought it was way too daunting!
