PEAKOET Extended Life Red/Pink Concentrate Antifreeze/Coolant for Asian Vehicles, 1 Gal.

Used when I changed my radiator and everything has been fine. Save money and buy this concentrate and mix yourself instead of the deluded coolant.

Bought 4 gallons of distilled water at big box store for $5. Drained 7.7 qt radiator 3 times (only about 3.5 qts come out) and filled with distilled water each time and ran 20 minutes with heater on and waited until thermostat opened for 5-10 minutes then drained to completely flush out old antifreeze. Only half the antifreeze came out each flush. Could not find the block drain on a 2004 Corolla that is said to exist. After final flush I managed to get 85% of the 100% concentrate into the radiator with the remaining ~3-3.5qts of distilled water making the required 50/50 mix. Drove a day and then put another ~8 ounces of 100% concentrate into radiator fill after system stabilized. Then mixed the remaining concentrate (~16oz) 50/50 with distilled water for topping off the radiator overflow tank to the hot full level.Trying to flush and fill with 50/50 premix would be very expensive since you'd be using expensive ($18-$22 a gallon) premix for the flush fluid. That's why I did it the way I did. Maybe if you could drain the entire 6.9 qts from the system each time this might work, but I never got more than 3-3.5 qts out each drain. Good luck.Don't believe the nonsense one commenter said about Toyota not accepting this.That's like saying BP gas isn't allowed but Mobil gas is. Antifreeze that is the proper type POAT, OAT, HOAT, etc. and conforms the the type number is just as good as OEM, same for transmission fluid and oil. Toyota doesn't make any of these fluids they spec them and farm them out to respected manufacturers. If a Toyota dealer drained it they are disreputable or it was the wrong formulation for your model and year (green instead of red, or pink, whatever your year requires, etc....)Do your homework. There are bad Toyota dealerships and service managers just like any other brands.

Every year I drain my old coolant and refill the new coolant to keep the radiator working safe to protect the vehicle from overheating in the future. It is a quality coolant and works as good as the original one. Recommend it. Great shipping ! Thanks !

Great price and fast service! JUst what we need in Arizona. Gonna be 114 today and running just a little low!

I always purchased concentrate coolant. Just add water and make it a 50/50 mix. You will save money over buying the 50/50 premixed. This is my go to coolant for toyotas. In the past year, I've purchased about 6 gallons. Serviced 5 toyota's. Purchased extra for reserve.
