Congratulations Dashan - glad it all worked out for you. Does it run any different? I should have mine done any day now lol.
Dean I'm going to take a closer look at the pump, perhaps when all the timing belt covers are back on. The PS level never goes down though (that's 250K of leakage on there).

I couldn't wait to bring the car out for a spin. The car becomes much quieter and more responsive after all of the work done. The engine sounds more like that of the LS430 which I recently tested driving (I am in the market for a 430). The increase of performance might also due to replacement of distributor caps and rotors (the old rotors were in very bad shape).

New Fan Bracket In
After the fan bracket installation, the wire harness to the crankshaft sensor was rerouted as it should have been to the back of fan bracket using a wire to lead the wire harness.

I just wanted to say thanks to everyone here, because I just finished my TB/WP/Seals change, essentially the same as Dashan here, and finally all seems to be working fine.

Cheers mate.
How many miles do you have on that thing? I had mine done at 75 and then 140K, and then I did this one myself at 245K. (Much cheaper this time lol)
Belt was in great condition too - almost looked like the new one.

OEM Parts that go 210K miles and beyond
My cars previous owner replaced only the timing belt at 120K to 130K miles. So the water pump, fan bracket, and timing belt idler pulleys are all original. I replaced all of those parts recently with the car at about 210K miles. The following is a few shots of the old parts and the analysis.

Fan Bracket
The fan bracket is in very good shape. There was no feel of bad bearing when I spined the pulley of the bracket. Compared with the new factory fan bracket, the pulley only had a little bit of the side-to-side movement. There was no feeling of anything loose inside the part when shaking the fan bracket.

Water Pump, Timing Belt Idler Pulleys
The water pump and LH side timing belt idler pulley moved smoothly. The RH side timing belt idler pulley has a bad bearing when tested by spinning the pulley. There are something loose inside all of the three parts when I shook them.
So, I would have not replaced the fan bracket, water pump, and the timing belt idler pulleys had I done the first timing belt replacement service my self at 90K miles, but the timing belt itself only.

Oh yeah, some parts will last forever but if you don't change them when you do the T-belt you're taking a BIG chance that they're gonna last another 90K. You're very lucky that idler pulley (with the bad bearing) and the water pump didn't lock up and wear the T-belt down to where it snapped. Personally, I might have let the fan bracket go some more miles. At least with that it's easy enough to get to if it does go out. But, you got that "piece of mind" that it wont. The idler pulleys are a given. (should be changed) When I did my second T-belt, (after 14K miles) the tensionor idler pulley was out of grease already. So, ya never know.

When you guys change your seals do you apply any grease(oil) on the inner side of the seal.
Because i did my without any lubricant i install them dry.
Is it a problem.
