    Upgraded instrument cluster from speedometer and 2 gauges to one with tachometer plus 4 gauges. Also completely replacing AC system, repairing dash pad cracks and restoring paint, as a start.
    The Owner's Manual for my 1987 Toyota pickup says to use "ethylene glycol" antifreeze which is green in color. But, the label of a Zerex Asian variety says it should be used in Toyotas, etc. It has a different color (blue?).

    Problem is, the owner's manual is vague about what was put in it on assembly back in Japan. And, on a bottle of G-05 (HOAT) antifreeze I read it is recommended for 1995 and earlier Toyotas.

    I'm new to the Toyota scene, so what's the best for my truck? I hear that Toyota "red" antifreeze is best, but this antifreeze chemistry is new to me. What's up?

    There are so many different anti-freeze formulations for different engines that I just don't play the guessing game. I go to the dealer and ask them what to use. Color means nothing. It's the make-up that does. Chances are that if you're engine calls for the green then just any green would work but I still wouldn't take the chance. You put the wrong stuff in there and you could be looking at some really expensive repairs down the road. To me, an extra $5 per gallon is good insurance especially since these 4 cylinders don't hold much.
