And that makes it roughly 2.5 times the cost of the OEM brand considering the Toyota stuff is pre-mixed.
+1, radiator drain and refill? since you only needed 1 gallon of 50/50.
I prefer the drain and refill with distilled water until clear or as long as you please. I do drive 25-50 miles between refills, going to and from work and then drain and refilling so most of the water DOES circulate. Then I add approximately 50% of the total cooling system capacity and top off with distilled water to get to 50/50 (obviously approximately). To me this seems like a good way to do a complete coolant flush, do this every 120k and your gonna be set!
I just changed the FF pink coolant in my 2008 Corolla at 74K using the exact method that you tout. I refilled the 6.9 qt. system with 3.5 quarts of Peak Global Lifetime full strength and distilled water. I should be good for at least another 75K.
75k? easily, I think your good for longer, reason I say this is because before BITOG, I used to NEVER EVER change coolant or my family members, we had 170k+ on OEM coolant on all our cars and none leaked or had any over heating issues and their radiator and all the pipes are all genuine, and nothing is rusted from the inside...if oem coolant can do that then your method could easily last 120k, at least from my experience with more then 10 cars we have owned in the family.
Edit: 00 civic I drove from 40k to 320k that finally got a bad head-gasket from poor diagnosis from the mechanics of whether it was radiator/water pump/thermostat/cooling fans or their switches and it was driven constantly while it overheated from changing things out step by step. This is all when I was younger!
