My coolant has turned from neon green to neon yellow. Imagine being extremely dehydrated and using the restroom, that is how yellow the fluid is. The engine reached 210 degrees twice when i was messing with the carburetor attempting to get it tuned in just right, but i am not sure if that would have anything to do with it. I have the Kirkham aluminum radiator and an all aluminum engine. I have used aluminum radiators in the past and had engines overheat, but i have never seen the
antifreeze change to this color. However, i have never used an all aluminum engine either.
So, why would this happen. Is this normal?
