Default 90k Serivce - Timing Belt and Water Pump
The car is a '99 GS300 with 103,xxx miles.


I have been searching around and I have the part numbers for the timing belt, water pump, o-rings, and the coolant for a TB/WP change. I noticed people are replacing the cam (2) and crank (1) seals as well. I can't find for the life of me the P/N's for them.

What else is recommended to change/replace on this service? I plan to do the service here soon after I change out the balljoints because the previous owner has put it off for ~20k miles after the dealer told her she should replace them from being worn out.
TIA.

If you are planing to replace the waterpump make sure you replace the thermostat also. Consider replace all of the dry belts....coolant flush...

These are the parts involved in the replacement...

--------------------------------------------------------------------------------

I sent this to another member last week because I'm changing my timing belt/water pump today...

I have a '98 GS 300 and bought parts to do the timing belt/water pump replacement. These should be Toyota/Lexus part numbers...

#13568-49036 Timing belt
#13505-46041 Idler, T/B
#13540-46030 Tensioner
#90210-26002 Washer
#90311-40020 (2) Oil seal
#90311-46001 Oil seal
#16100-49876-83 Pump assembly
#90916-03093 Thermostat
#16325-62010 Gasket for thermostat
#96761-24022 (2) O-Ring
#96761-24028 O-Ring
#99366-D1930 V-Belt

Parts w/ tax came out to $502.61. Now I gotta find a reputable shop to do the repair.

Hope this helps.

I have a 2001 GS430 Ltuned which I need to service for the 90K. Are the parts listed the same for '01? Are those all of the parts which Lexus replaces? I was going to call them and ask for a quote, I have a feeling it could be close to a $2k bill. I found a local mechanic here that may be able to do the work, but want to make sure I can get all the parts. Any help would be appreciated - - thanks!

Calvin? Wait you're the guy that's across the street from me right? lol
If you need help on your timing belt let me know. I have all the special service tools from Toyota to do the job. The crank pulley bolt you will DEFINATELY have fun on without my crank pulley tool

I also have airtools to make everything go faster with less effort.

So this is the comprehensive list for the timing belt service? What else is recommended with the 90K? I'm at 91K and need to do this soon. Change all fluids, spark plugs, spark plug wires, check brakes, sensors, all the usual? Is right around $500 the best online price?
