All 4th Gens came with Toyota SLLC, aka Toyota Pink. Toyota "red" LLc is not backwards compatible with SLLC

weird.

when I did my timing belt last year(the year before?) I went to the dealer for my coolant, they told me it took the red, so that's what's in there...

Your '06? That's the wrong one. SLLC is a no silicate formula among other things, LLC is a low silicate formula designed for older vehicles before about '03-'05 (think 1MZ, 5VZ, ect.) You can use SLLC in a car that calls for LLC, but not the other way around. I'd flush it out around 30k or so with SLLC and make sure you drain everything out to get as much of the old LLC out and then switch back to SLLC (remember after the first 10yr/100k interval Toyota calls for a 5yr/50k one with SLLC.)

An additional note is that LLC is non-diluted while SLLC comes premixed in 50/50 and 60/40 offerings.

yep, the 06. damnit.
that shit wasn't cheap either.
 
Maybe the dealer would replace it for no charge since it was their mistake? Worth a try.

Search is always your best friend. Short answer, SLLC (pink) and LLC (red) are 100% compatible. Toyota has said so themselves: http://www.toyotapart.com/ENGINE_COOLANT_COLOR_CHANGE_T-PG010-02.pdf
Genuine OEM Parts for Your Toyota

Per the bulletin, follow the service intervals in your manual regardless of flavor. LLC will have a shorter change interval than SLLC.

Pretty sure my '03 2UZ actually came with LLC, but I switched to the pre-mixed SLLC when I did my first coolant change. Dealer also appeared to use SLLC with the timing belt/WP replacement. I'm probably getting close to due again.

I believe that was updated later down the line, as in 2002 few vehicles ran SLLC. The main difference between the two is that SLLC is a Non-Silicate among other ingredients (or lack there of). There's a newer I believe that details the backwards compatibility of SLLC in LLC, but not vice versa. Toyota has been a bit wishy washy on stuff like that in the older days (look at WS ATF for example.)

All 4th gens came with SLLC, it was phased in around that time and LLC was phased out. A big reason for the change is the longer intervals would result in silicate drop-out:

(I do apologize for the picture size, it's something I snagged off the web.)

Where the silicates actually drop out of solution and clog up and corrode the cooling system.

I am happy to see this thread, I have 05 4Runner V8 and I have both red and pink coolant sitting in my garage (never knew the difference but dealer told me it was the same) and change my coolant every 2-3 years...now I will make sure I use pink.....

Hi im in a little bit of a bind here and was hoping for some clarity. Im still new to this board so im not yet allowed to start a separate thread pardon me.
Without doing extensive research, like a moron i topped off my pink coolant with about half a quart of asian zerex red into the reservoir tank. Under normal circumstances i would get a flush right away but i just dropped almost $200 last saturday on pads and rotors and im tight on money.
I guess my question is, is the new mix of coolant corroding my engine as we speak? Or can i get a flush next month when i get my paycheck? The jug of zerex does say silicate and borate free so i dont know how much that plays in my favor. I topped off 2 days ago. Thanks in advance to whoever can help with this. Btw my car is a 2004 v6.sr5 95,000 miles

Zerex Asian Formula should work fine, last I checked it was in fact compatible with SLLC. So you're fine. :)

BW, notice my 2nd link is to the current Toyota USA Owner's page.
toyota.com->owners->parts&service->genuine toyota parts->service fluids
As of this morning, that page stills shows SLLC and LLC as compatible.

Could you possibly have seen a warning about GM's Dexcool (aka DeathCool)? It was also available in a pink formula and there were stories of it gelling when mixed with certain coolant formulations.

For general reader knowledge based on some statements/questions in this thread. Coolant color is meaningless when comparing across different brands. It's the chemical makeup that matters, the color is just a dye.

Yes coolant colour isn't as significant an indicator as one would hope.

SLLC is Backwards Compatible. meaning if you have a vehicle that takes LLC you can substitute it with SLLC; but a vehicle that takes SLLC cannot use LLC. This is because LLC is a low silicate formula among other things and SLLC is a silicate-free one.
