AISIN kits. All the way. They're the OEM for the timing belt/seals. I am fairly certain the '05 is identical to the '06. This is what I got.


You'll also likely need a jug of coolant. I get that at the Toyota dealer. It's all basically the same price everywhere for the "correct" coolant, so I figure it makes sense to get it there. Dealer is only 0.75 miles from my house, though, so you might opt for a different option.

Thanks for the amazon links! I see a lot of confusion on these forums about the correct coolant so I think I'll just go to the dealer. Do I need one gallon of coolant or two?
So, I am not 100% positive on this. I've never done a timing belt change. I was going to tackle it myself and then had an impromptu 800 road trip come up and had to pay to have it done. I delivered the timing/water pump kit, the seal kit and two belts with my van and they said it would be about 2 hours. I called them after 5 hours and they said they just finished up because they had to send someone over to the dealer for a gallon of coolant. I think the full cooling system holds 3.5 gallons, but I don't believe you have to drain it down to replace the water pump. Maybe someone else (@paul r ?) can chime in on how much it required.

Gotcha. I just called the dealership and it's $30 per gallon!!! Is there a reputable place to get this online or a solid alternative by chance? Thanks!
Gone are the days of getting a gallon of the green antifreeze (not 50/50 pre-mixed stuff) for under $5.

I have a 2002 Toyota Sienna XLE and a local mechanic is asking to replace Timing Belt. He said it will cost $1000 to do the job. Is it that costly? Please let me know. You can reply to [email protected]. Thanks.
You might pay as little as $600 or as much as $1600 depending on your particular area and the specific mechanic. I think I recall the flat rate estimate is 6 hours and some mechanics in my area (i.e. the Toyota dealer) are approaching a $200/hr. labor rate plus the cost of parts.

I paid $1264 last year for the same job. That included exterior belts too plus anti-freeze. The mechanic bought all the parts, with a nice mark up of course. Mines a 2006 Sienna xle with 233,000 miles and never had any belt replacement. I bought it and right away had the timing belt kit put in it. Sure the belt looked worn and may have given out soon. I have put 10,000 miles on it now and its going strong still. Haven't done that much to it. Engine light has been on for like 8 months now. It goes off when i add additives for the front catalytic converter fix. It still runs ok. I just do the right thing and ignore it-lol. It doesn't have any rear brakes, maybe 10% but it stops good enough. Everything else works though. For a $2600 vehicle its a good one. Scotty Kilmer persuaded me to buy a Toyota ,so i did. He was right about them. I hope to get to the 300,000 mile mark with this one.
Well, I would STRONGLY advise you to replace the rear brakes! With the XLE, you should have traction control and 4-wheel discs. If you have any kind of emergency braking and/or traction loss, you may find something bad and unexpected happens. But, yes, I have a similar experience with mine. I've put roughly $1000 per year into the van for the past 3 or 4 years, but, before that, it was on the order of $200 or less per year. I have to address the rear end ($1500) soon and will probably need a whole new exhaust ($1500) in the not-too-distant future. After that, I expect the van to return back to a $200/year cost.

At how many miles did you start getting into the 1k/year repair costs? Is that parts and labor? Thanks!
It was a mix of parts (for stuff I did) and parts (typically supplied by me) and labor for stuff I had the mechanic do. My '06 has around 140k miles on it right now. It was probably 5 years ago (110k miles) when I got a cat efficiency light and the mechanic (who never steered me wrong until this point) insisted the front manifold/cat needed to be replaced (for $950) and when I asked if he could change the A/F sensor at the same time, since he was already doing stuff, he said it would be another $500 (30% markup on the Toyota part price plus an hour of labor). At that point, I decided I wouldn't ever let them touch the van again. That pushed me into trying to preemptively figure out what needed to be done, so I could do it as I had the time in the nice weather. As such, a lot of stuff which had never been done before (front suspension, O2 sensors, timing belt/water pump, etc.). My every-two-years safety and emissions inspection has identified stuff which needed to be done. Front flex pipe wore out for my 2017 inspection and then rusted through again by my inspection I had done last month along with a couple other rusty exhaust issues, which I had them deal with. Mostly, the stuff that's costing money are, depending on your perspective, lucky that they lasted this long or unlucky that they all failed around the same time. I mean, I still have all original wheel bearings, rear shocks, radiator and hoses, and a bunch of other stuff. Some people have them start failing just after the 100k mark. Others have them last until 250k. With me putting on so few miles, though, time (and beach salt and winter road salt) is the primary killer for me.
