Eeek Radiator Fluid Options

[cibrit-]

Hey guys!

Alright, so I change my oil today and before I did it I checked my other fluids. I opened my radiator cap and looked in... the fluid is brownish.

My question is:

Could this just be because the radiator fluid is to old?

If not what else could the problem be?

Dexcool isn't all that great, it has plastic softeners in it, which is most likely the reason GM has problems with plastic intake manifolds.

I can't remember what year Toyota started using the red coolant, but it doesn't really matter, the recommendation to use the red backdates, just like putting Dextron III in trans that originally took Dextron II.
That's the recommendation.
You can use green, or whatever you want. Toyota suggests if you use anything but red to get a low silicate forumula, according to them silicates destroy water pump seals, which is why they don't use them in their coolant.
