2004 Corolla 100,000 Miles - 120 Months
Replace engine coolant 2
2) Initial replacement at 100,000 miles/120 months. Replace every 50,000 miles/60 months thereafter. See Maintenance Definitions (Engine Coolant) for details.
Ok.. Lets go check the "Specifications Manual".
From page 253 -
COOLING SYSTEM
Total capacity, L (qt., Imp. qt.):
6.5 (6.9, 5.7)
Coolant type:
“Toyota Genuine Long Life Coolant” is
filled in your Toyota vehicle. In order to
avoid technical problems, we strongly
recommend using “Toyota Genuine Long
Life Coolant” or equivalent.
With ethylene−glycol type coolant for a
proper corrosion protection of aluminum
components
Do not use alcohol type antifreeze or
plain water alone.
Please contact your Toyota dealer for
further details.
Toyota Genuine Long Life Coolant = Toyota LLC (AKA Red).

The interval for Long Life Red is LESS than Super Long Life Coolant. If the manual calls for the 100k initial change and 50k subsequent change interval, then the coolant spec-ed is SLLC. It was likely an error in the manual because some of the Corollas may have still been filled with Toyota Red and not the pink SLLC. You can ask any dealership and they can confirm that the interval for Toyota Red is significantly shorter than SLLC.
Here is one document from a Prius manual which clearly illustrates the difference in the interval between Red and Pink.
Quote:
SLLC is pre-mixed (50% coolant and 50% distilled water), so no dilution is needed when adding or
replacing SLLC in the vehicle.
_ If LLC is mixed with SLLC,
the interval for LLC (every 25,000 miles / 40,000 km or 24 months) should
be used.
_ You can also apply the new maintenance interval (every 50,000 miles/ 80,000 km) to vehicles initially
filled with LLC (red-colored), if you use SLLC (pink-colored) for the engine coolant change.
Note: I guess for certain models it is OK to use the longer SLLC interval if you find a way to replace all of the Toyota Red LLC with the pink SLLC, but good luck doing so without a coolant exchange machine.

Well I’m glad that your incorrect service procedure has worked for you, but you are truly doing a disservice to other members by portraying that it is the correct way to service a cooling system, when it is not. There are obviously many risks to an improperly bled cooling system. If you do not allow the engine to idle until the thermostat opens (as evident by the change in coolant level within the coolant funnel), there is no guarantee that you would have removed all of the air pockets.
Also, Zerex Asian is a “clone” of Toyota Red according to Zerex. There has been no formal OEM approval of the product. In other words, you’re taking the supplier’s word for it – you need to make that fact clear to a new member who may not be as familiar with the pros/cons of an unapproved product.

I don’t think we are disputing opinions here, we are disputing facts (more so than not).
I've been DIYing Toyotas for years, spend the time to share with the OP, and I'm told its a disservice. Gotta love BITOG. Anyways you can't use service intervals to determine the type of coolant. Different models can run different intervals with the same coolant. Have to go by the name of the coolant listed in the manual. I provided that fact. Enough squabbling, the OP needs to tell us what he see in the expansion tank. If its Pink it will be obvious. If its Red it wont look perfectly red because its old and contaminated. Will look "rusty red".
