#370 of 399 Re: Timing Belt / Water Pump [steelerx6] by jcz65 May 11, 2009 (12:05 pm)
Replying to: steelerx6 (Apr 07, 2009 8:25 am) Just had water pump and timing chain done; cost me about 650.00. I semi trust the shop that did it. The labor is the problem with this as they have to take off so much just to access the water pump.

Replying to: mweinste (Apr 07, 2009 8:06 am) I have this as well, Also, every now and then it just won't start. Leave it alone for a day or two and it starts just fine. Dealer was no help. Hours of googling seem to suggest the solution is carb cleaner in the Idle AIr Control Valve, or as a last resort replacing the valve. Has anyone tried this, and did it work?

Replying to: mrg10 (May 31, 2009 10:25 am) Cleaning the IAC valve took care of the problem. I found the fix on Edmunds and faxed it to the repair house.

Replying to: steelerx6 (Apr 07, 2009 8:25 am) I have a 2005 Sienna with 99000 KM (60,000 miles?) and I just visited the local Toyota dealer in Cancun, Mexico. I asked about the typical or recommended interval between water pump changes. (All my experience is with belt driven water pumps.) The response I got took me by surprise. The service representative stated the water pump fitted on my model of Sienna is electric and essentially they replace it only after it has failed. I immediately questioned this so he pulled out a diagram of the 3.3 liter V6 and sure enough it showed an electric water pump. Did the pump change to an electric type after 2004?

Replying to: steelerx6 (Apr 07, 2009 8:25 am) Yes you should have that done as soon as possible, if you haven't done at all since you own the vehicle. Typically because of the labor involved, the water pump is right there when they service the timmimg belt, so you can "kill 2 birds with one stone" so to speak. My recomendation is to use a mechanic that you trust rather than the dealer (for they are much pricier than other mechanics- unless offcourse you still have warranty on the vehicle.   It's better to be safe than sorry, the brakeage of the timmimg belt will ruin your engine. Trust me I fell in the same thinking with a nissan that I owned, but this time they were right. I didn't replace it, when it broke, it ruined the valves permanently. (a very expensive job) I ended up getting rid of the car
#375 of 399 2001 Sienna timing belt by laman400 Jun 07, 2009 (3:03 pm)
If the timing belt fails on a 2001 Sienna XLE at highway speed of approximately 70mph, will it harm the engine components such as valves, etc, or will the vehicle simply lose power and come to a controlled stop? I have heard that the 2001 Sienna has the type of engine that will survive a timing belt failure without causing any other engine damage. Is this correct? Also, I have just turned 100,000 miles on my 2001 Sienna. I know the maintenance manual calls for timing belt replacement at 90,000 miles. My local Toyota dealer is telling me that the timing belt on my 2001 Sienna should last for 300,000 to 400,000 miles or at least 15 years. My van is running perfectly right now. Should I believe what the dealer is telling me, or should I have the timing belt and water pump replaced now at 100,000 miles? Thanks for any help.

Replying to: laman400 (Jun 07, 2009 3:03 pm) Get the belt and pump replaced according to the schedule - which it appears you have already passed the 90k point. An engine always "is running perfectly" when the belt breaks. Belts and pumps are cheap compared to an engine replacement of 5-7 thousand $.   By the way neither of these parts lasts to 300,000 miles.   AZdino ---
#377 of 399 Battery Size Difference ??? by thksnow Jun 21, 2009 (7:55 am)
I have a 2004 XLE FWD, and I just replaced the battery. From everything I could determine online, 24F is the correct size. Based on good reviews in Consumer Reports, I bought the EverStart Maxx 24N at Wal-mart. Only after I got it home and started installing it did I realize that it's about half and inch smaller in depth (front to back), and thus the top bracket is way to big. I used some wood pieces to make the bracket fit tight, but was wondering if anyone else has had this problem. I can't remember ever having this problem before with other vehicles. Should I be concerned?   I went on-line and found the specs for the BCI Group Numbers, but they list the sizes as "Maximum Overall Dimensions", thus I guess smaller is acceptable.   Thanks for any advice anyone has.

Replying to: thksnow (Jun 21, 2009 7:55 am) Funny thing is once I had the opposite problem - the battery was just a tad too big.   I think you'll be OK as long as nothing works itself loose. Check it each time you check the oil.
#379 of 399 2007 Sienna Struts and Steering Rack by crestonave Jun 25, 2009 (9:07 am)
I just had the struts replaced, under warranty, on my 2007 Sienna XLE Ltd AWD. The left front strut was making noise and Toyota advised that upon inspection they found a leak in the right front strut also. In addition, the steering rack was leaking. The car has slightly less than 19000 miles on it. Toyota told me that they verified that the problems were "factory defects" and covered under warranty.   Does this make sense to anyone? Anyone else experience this kind of problem with a supposedly super-reliable vehicle such as the Sienna?
