Here are some maintenance schedules i ran across.

Wow, look at the difference in frequency of recommended air filter replacement between the the 2000 (every 6 months) and 2002 (every 36 months) schedules!
Could this be a misprint/mistake?

Strange! The coolant replacement is at 96K interval?

Strange! The coolant replacement is at 96K interval?

Based on their appearance (i.e. distances are in kilometers), I assumed that these schedules are for Canadian models. I have compared them with two independent sources, including Toyota Canada Web Site, and confirmed that these schedules are accurate.

Looking at coolant replacement, the Canadian Manual Supplement, where you can find the schedule, says:

“Replace Super Long Life Coolant initially at 96 months/128,000 km, thereafter every 48 months/64,000 km”

Searching Internet for the U.S. data, I found that http://smg.toyotapartsandservice.com/ says:

“Initial coolant replacement at 100,000 miles/120 months. Replace every 50,000 miles/60 months thereafter.”

Apparently, Toyota assumes that Canadian driving conditions is a harsher environment, therefore various replacements are scheduled more frequently.
Unfortunately, the site I found is not a good place to extract maintenance schedules in such a nice format as posted above. I hope we will get those posted here very soon.

In terms of coolant replacement, does everyone out there combine "distilled" water with the ethylene glycol coolant?

 

[robo5]

I just use regular tap water but that's me.

Hey robo5,
Thanks for responding. I typed into google and I found this link http://www.eetcorp.com/antifreeze/antifreeze-faq.htm#q17
It contains a small book of info about antifreeze. Here is an excerpt from the site:

"If I buy concentrated antifreeze, can I get the proper water/glycol mixture using tap water?
Using “hard” water out of the tap can cause scaling in the engine. Tap water is purified for drinking by chlorination, which kills germs but can cause corrosion in the engine. Even if you carefully measure the amounts of tap water and antifreeze to get the right blend, using tap water is not a good idea. Tap water also contains dissolved oxygen, calcium, magnesium, and other contaminates besides chlorine and chlorides that can significantly degrade corrosion inhibitor performance."

Hi All,

I decided change oil & filter every 5K km even so Toyota recommended every 8K km.

Thanks,

Distilled water is "ideal", but most of us don't have the time (or a readily available supply of it) to do that. I wonder what dealerships use...??

I have specifically gone to the grocery store to buy distilled water (for the radiator as well as for the battery), but not all stores carry it. So then it becomes a wild goose chase where the benefits may not outweigh the convenience (and cost of time, gas, wear-&-tear, etc) of just using tap water.

So, we make do the best that we can with what is readily available....

Here's a link I found to DIY distilled water:

YMMV.
Good Luck!! 8)

I know some chemistry. It probably does not make any difference if you use tap water or distill water. You are adding so little water each time. This is not like a hot water heater that takes in thousands of gallons of water a year. Over the life of the van, it will be surprising if you use more than 10 gallons of water for the radiator.

Also, unless you water has salt in it (you are using a water softener), it will be fine.

The engine is seldom the part that fails in a car these days. If you plan to keep the van for a long time, I recommend taking better care of the body with frequent washings. For people in regions where salt is used for snow, the body will rust out first before the engine dies.

I have read that Toyota's "Super Long Life Antifreeze/Coolant" is available only as a "pre-mixed" product, which is not to be diluted, so you don't need any water at all.

Pre-diluted coolants are almost as expensive on a per-volume basis as the concentrates, so they are almost twice as expensive as buying concentrates and mixing with nearly free water; on the other hand, distilled water is far from free. Although I have filled many cooling systems over the years with coolant which I mixed, I'm inclined to buy it ready-to-go for the Sienna.

My Sienna's cooling system is currently filled with genuine (no water added) Toyota Super Long Life Antifreeze/Coolant.

Also, unless you water has salt in it (you are using a water softener), it will be fine.

All tap water has some salt, and some municipalities add quite a bit in a softening process at the water treatment plant, so even if your home does not have a water softener the tap water might perhaps be significantly salty.

The nearest major municipality to me (Edmonton, Alberta) stopped softening their water a while ago, so it is now less "salty"... but it has more calcium and magnesium (the stuff the softening process was removing).

Thanks for the coolant info. My 2006 Sienna has 55,000 miles and I was feeling the urge to change the coolant. On inspection, I found the pink coolant was still quite clean and the anti-freeze tester said that I am protected down to -25 degrees Fahrenheit.

I wonder if the pink color indicates the long life antifreeze?

Take Care,

I wonder if the pink color indicates the long life antifreeze?

I believe that this, from Chemicals | Toyota Owners Online, says the answer is "yes":

Genuine Toyota Super Long-Life Antifreeze/Coolant is the same high quality factory-fill product found in new Toyotas. You'll know it by its distinctive pink color.

This page does not mention the existence of any other current Toyota coolants.

Hi All,

I'm looking at the posted service schedule for the 2004-2005 models.

It reads, for 2005: "2005: all V6 and V8 models except 4Runner V6, Tundra V6, Tacoma V6" (those trucks had timing chains). So for Siennas it appears to say that the timing belt is due for replacement at 72-months/96,000kms - and then again at 102-months/144,000kms. It's the same story for the 2006 (though that pdf actually includes a timing belt change schedule for the 2007 Sienna ;-)

Why the reduced interval for the second belt? That seems quite soon for such an expense.

I'm looking for a 2005-2006, so I want to know if the vans I'm looking at are due for a major and expensive service.

thanks,
Bill

On the bottom of the pdf it says '72 months or 144,000KM, whichever occurs first'. I can see where it is confusing. But no you do not have to replace the second belt more frequent. It is a time vrs. KM (mileage) thing.

Ah, ok thanks.

It didn't register that the 72/144,000 at the bottom didn't match what was up above.

So the 96,000 must refer to other listed servicing under that column.

cheers!
Bill
