a friend and i are going to do the timing belt in our 99 gs4.

can someone provide me a full parts list (and part numbers if possible) for everything that i will need for this service.

all i know is i need the timing belt itself, a water pump, and a belt tensioner. i've been told that i need to replace as many oil seals as possible as well while everything is apart, but the only one i know of is the crank seal.

any help appreciated... thanks

 

ne1? no one here has done their timing belt?

 

i would call lexus to be on the safe side or get the service manual

 

my local lexus dealer is not very helpful. they are more interested in making money doing the service and selling parts at full retail to those who don't

they wanted $600 for the service manual!!! is it possible to find someone who sells it for less?

 

$600... i hope you are kidding

contact club lexus vendor darell diller aka sewell lexus

Sure thing Ben. Try ordering a belt for it and see what they say. He he. No timing belt Ben. Timing chain. No need to replace.

 

what are you talking about ??

there is no timing chain or am I wrong

 

So you are saying our cars our chain driven and not belt driven?? Pretty sure it is a belt but ok.

As for a list with part numbers - here is what I have

13503-0F010 - Idler S/A Timing - $74.62
13505-0F010 - Idler S/A Timing - $74.31
16100-59275 - Pump Assembly, Water - $124.65
90916-02586 - Belt, V-Ribbed - $82.34
13568-09070 - OHC, Timing Belt - $54.87

Hope this helps,
Jonny

 

thanks jonny... it's a start!

but... what's the difference between the first 2 that u have listed above?

is the v-ribbed belt the serpentine belt?

anything for oil seals, like the crank seal, that they say should be done at the same time?

 

Hello Mr. Guru,
All of the Lexus engines used belt.

Anyone else see the humor in this???

 

Hey man,

I am just going off the invoice I have so I am not sure what the differences are. As for seals

90311-A0001 - Seal, Type Oil - $7.66
90311-71001 - Seal - $16.33 x2 = $32.66

Hope this helps.

Jonny

 

thanks jonny... you've helped me a lot

 

You are welcome man. Hope it all works out.

Bumping an old thread. Does anyone know what the idler sub assembly is? Does it really need to be replaced as part of the 90k?
