    2020 Tundra SR5 + 2003 Tundra SR5
    The 2020 has a Ranch Hand front brushguard/bumper
    This is *actually my wife's 2003 4Runner which I understand to have the exact same engine as my 03 Tundra. Both 8 cylinder.
    I have been unable to find which coolants are acceptable or preferred.
    Thanks.
    Found lots of 'leak fixing' in the archives but no 'which coolant' on tundras.com

    I bought up 8 gallons of toyota red for $10/each before they stopped making it a few years back.

    I may have quite a few left over if I decide to sell my truck to get a new 2022 Tundra.

    bought 2 gallons of straight red from the local stealership for 16.50 ea. equivalent to 4gallons mixed... I have a gallon jug pre-marked, so I don't have to think or do math.

    I'll have them pour out the water and only buy the good juice at half the price!
