Toyota rates the red as good for 50k in new cars and the pink at up to 100k in new cars. Sorry blizz, read the jugs.) The pink has a HOAT (hybrid organic acid) and the red is OAT (organic acid) Technology for corrosion protection. First, pink is NOT just pre-diluted red as many misinformed posts state.(edit: like the one above. The differences are in the special mix of additives for corrosion protection and the color dye they stick in. Almost all anti-freeze is mostly ethylene-glycol and distilled water and as far as boil and freeze protection they are all IDENTICAL. What you do after that is up to you and it mainly depends on what change interval you use. The dealer is describing to you how the trucks came from the factory. There are going to be lots of opinions on this. In all our toyotas (95 and 99 camry, 00 and 12 4runner, 04 sienna) we use toyota red (its the same as pink, just concentrated and cheaper) buy yourself a few gallons of red and a few gallons of distilled water and you're good to go for a few years.ĮDIT: RED and PINK are not the same, and PINK has a longer change interval based off TheDurk's information. If I use the pink, I would have to buy two gallons as it is already diluted but will be more expensive of a buy. One thing I have considered, if I go full strength I only buy one gallon and one gallon of distilled water. My concern is this, what does everyone else use in their trucks given the above information and what recommendations can you make? I have a 2000 3.4 and I'm replacing the radiator and am undecided on the correct coolant. They tell me that T4R up to 2004 uses Super Long Life (Red) and T4R from 2004 to Present uses the Long Life(pink) which is also the diluted mix hence the lighter color. Okay, Just got off the phone with the dealer.
