Prestone Coolant ?? Help

Newbe here. I just purchase a use 2005 with 94,000 and am very pleased with the car. I now have 101,000 and need to do the recommended maintenance. I live in very rural Maine and there is no Toyota stealerships near by. I've looked through the posts now for several days and cannot find an answer to my current problem. I changed the inverter coolant as per usbseawolf2000's youtube video. (I drained 2 quarts plus one cup, but could only put back in a tablespoon less than two quarts, even after a week of driving.) My problem is I think I might have screwed up and put in incompatable coolant. I purchased and used Prestone as the local autoparts store said it was equal. Researching the issue, I think it may not be equal and Prestone has yet to return my call or answer my questions. Here are the facts:

From the Preston website -
Prestone® 50/50 Extended Life Prediluted Antifreeze/Coolant Extended Life (AF-2100) Water, Ethylene Glycol, 2-Ethyl Hexanoic Acid Sodium Salt, Sodium Hydroxide, Neodecanoic Acid Sodium Salt, Sodium Tolytriazole, Dye, n-Propanol, Polypropylene Glyco

For those consumers who would feel more comfortable using a phosphate-free antifreeze, our Prestone® Extended Life 50/50 Antifreeze/Coolant is phosphate, silicate, and borate free. This coolant uses a special chemistry and technology that extends the life of the corrosion inhibitor package so that it lasts for five years or 150,000 miles (whichever comes first), and is safe for all cars and light trucks (old or new).

From the Toyota Owners Manual -
Only use "Toyota Super Long Life Coolant" or similar high quality ethylene glycol based non-silicate, not-amine, not-nitrite, and non-borate coolant with long-life hybride organic acid technology. (Coolant with long-life hybrid organic acid technology is a combination of low phosphates and organic acids.)

I note the following Toyota requirements vs Prestone:
1. Ethylene glycol based - Yes
2. Non-silicate - Yes
3. Non-amine - Not addressed*
4. Non-nitrite - Not addressed*
5. Non-borate - Yes
6. Low phosphates - No phosphates
7. Low organic acids - Not addressed*

* I'm not a chemist and don't recognize these listed in the ingredients

Would someone help me and let me know if I should immediately drain, flush and refill the inverter with Toyota coolant or if I am good to go because it is a "similar" coolant. Also, am I in danger of harming the inverter because I am a cup short of putting back in what I took out. If I am, how do I get the air out? I bled two tablespoons of liquid from the bleed valve without getting any air after the air stopped coming out. All measurements are very accurate.

A side note: Patric Wong, you are a terrific poster who has helped many with your excellent advise. However, in 2008, you made a statement I would like to correct. You said adding antifreeze to water increases the heat capacity of the coolant as it makes the coolant more dense. Ethylene glycol has less heat capacity than water, therefore, adding ethylene glycol to water decreases the heat capacity from pure water. What adding antifreeze does is provide a lower freeze point, a higher boiling point and lubrication and anticorrosion properties along with increasing its viscosity.

 

The car now has 170,000 miles and is running well. I did nothing about the coolant. I did not drain it and refill with a new coolant nor did I ever add a cup to equal the amount removed. The system is full and there have been no problems.

However, it was stupid of me to have drained any in the first place. It had just been drained and refilled by the dealer on the warranty issue mentioned in the reply posting before I purchased the car. I just did not know this but discovered it when I went to the dealer on another issue.
