90K service

[cefalu]

I am getting ready to do my 2nd 90K service on my 2004 V8 Sport. Should I stick with genuine Toyota parts, or are aftermarket parts just as good?

I plan to change the timing belt and all bearings, filters, plugs, water pump and front pads/rotors, change coolant, change PS fluid, and flush the brake fluid.

Is there a "best" place to buy the 90K service kit?

Looks like no one does their own water pump / timing belt replacements here.

But to answer my original question, my research concluded that Rock Auto had the best prices for the parts.

$195 for the water pump, metal gasket, toothed belt, tensioner and bearing, and idler pulley. Then Denso iridium plugs for ~$6 ea. This is an Aisin kit so it is OEM for Toyota. I stopped by the Toyota dealer for coolant, but they wanter $90 for 3 gallons of 50/50 premixed. So I went to NAPA for 3 gallons of Zerex Aisian car coolant for less than half the price of the dealer.

All in all a big job to change the belt and water pump, But the whole service was just shy of $300 for all the parts.

And my engine is noticeably smoother.

You already completed the job? Any issues along the way? I used blackworksinc's writeup and it went relatively smoothly besides some hiccups along the way such as the crankshaft bolt and a broken tensioner pulley. Still very much worth it to save the $1700 price tag.

Yes, it's completed. Nothing eventful along the way. I left the radiator in and used the starter motor to undo the crank nut. I was replacing the spark plugs too, so all the plugs were removed when I spun the motor. Worked perfect, no drama at all.

I used the Aisin kit so it came with new belt, idler pulleys, a new tensioner, and a waterpump too. I didn't reuse any of those parts. For $195 for the whole kit it wasn't worth taking the chance on a belt component on an interference motor.

The part that wasn't explained very well on the internet resources I saw were how to remove the alternator, and that the power steering pump pulley had to be removed to get the alternator out. Then the fan bracket bolts at the AC compressor were hard to locate. I also used a paint pen to mark the existing belt to transfer to the new belt. Not really needed, since the new belt had marks, but a good back check. It was worth the $1,700 I saved.
