FYI, most of the parts are available from Toyota, but I am missing some part numbers. If you buy from Toyota (non-lexus) you can usually get much cheaper, at least what I was able to find.

Timing Belt 13568-09070 $44
Timing Belt Tensioner Pulley 13503-0F010 $69
Timing Belt Idler Pulley 13505-0F010 $69
Water Pump 16100-59275-83 $107
O-Ring for the back of the water pump small one in the pic of parts above 96761-35035 $3
O-Ring for the water inlet housing large one in the pic above 96761-35035 $3

Not Toyota - Lexus specific:

Tensioner cover 13553-50020 (I have seen this on some postings as something to replace-anyone have an opinion?)


Does anyone have part numbers for these????

Thermostat and Gasket
O-Ring for the T-Stat (I thought this was with the water pump ???? anyone????
Timing Belt Tensioner

Im lost why do you need to disconnect the AC condenser?

 

Nevermind I see you just need to remove to bolts and a bracket from the compressor

 

Does anyone have the contact info of the mechanic in NY (?) who does timing belt in about five hours?

 

Thanks so much for doing the video. Great job mang

 

Timing belts are alot easter then people thing especially with a marked belt there is no guessing,

 

speaking of timing belt I found a great video on YouTube . it was on a LS430. I'm still having Toyota do mine. no way I'm tackling that

wrong forum

 

props for taking the time to write this up !

 

When replacing the timing belt I put a 19mm socket on the large cam pulley bolt to turn it slightly to slacken the old belt just a bit so it will come off easily. However, the bolt loosened instead. I then checked the other camshaft pulley bolt and each appeared to have only about 15 lb-ft of torque. Is this correct? Shouldn't large bolts like this be tightened down more than this?

 

FYI...my research has uncovered that the main timing belt parts (timing belt, water pump, timing belt adjuster, timing belt idler pulleys, serpentine drive belt) used on the LS430 are the same as used on several other Toyota products: 98-07 Lexus LX470, 01-07 Toyota Sequoia, 01-07 Toyota Tundra, 98-07 Toyota Landcruiser, 98-07 GS430, that share the 4.3/4.7 L V8 (there may be more). I would source them from the best supplier/dealer at the best prices. I have been very happy buying parts from this website's recommended dealer: Sewell Lexus. (Their clear parts diagrams, low pricing, and quick delivery are hard to beat).

I have for comparison, sourced the Aisin TKT-001 timing belt kit (water pump, timing belt, idler pulleys, gaskets/orings) from Amazon and found the quality of the parts lacking. (One of the idler pulleys had play, and the water pump had sharp edges on the pulley, which might cut the timing belt). It may be possible that I had bad luck and received defective parts, or returns from another customer, I will never know.....but I returned the kit.

It is interesting to note that neither the factory or aftermarket water pump had any identifying marks to distinquish between Toyota or Aisin.

In my humble opinion, factory/oem parts are the better long term bargain, (especially on critical parts, such as the timing belt and related parts,) and I will likely never again consider aftermarket parts.

 

Can anyone speak to the quality and differences between the Gates kit, the Aisin kit and the AC Delco kits? From what I can tell, it seems the Gates kit has the tensioner but not the gasket, the Aisin has the gasket but not the tensioner


vs



The ACD kit seems to have everything


I believe Toyota sometimes uses the Gates parts as OEM, but then AC Delco is also a pretty well respected OEM manufacturer. Any thoughts on which kit to go with, advice etc.?

 

Aisin is OEM and recommended by a Lexus technician is this thread or one like it. not to sure about Gates but it has to meet or exceed OEM so I'm sure it's just as good as What Lexus uses .
