I bought a 1996 GMC 2500 4X4 7.4/454 motor 4L80E transmission,219.000Km/137.000 on it.
I looked at the coolant in it when I drew some out with a hydrometer to check freezing point, I got -20°F but my question is that it appeared almost to be maybe yellow or real light green?
It sure does not look like the orange/pinky Dexcool we use in our C5500 shuttle buses, so am wondering if previous owner changed it out, and now I am wondering what I should use in it.
Any help?
