After reading other threads about coolant, I noticed Sierra has never
been mentioned. Recently, I put in a new rad, hoses, and water pump... I
thought I'd try the Sierra, as it's supposed to be less
caustic/corrosive, and otherwise less problematic.
Has anyone else used it, and what do you think of it's ability to keep
the rad from clogging?
Sierra is a propylene-glycol based "safe" antifreeze. It is supposed to
be non toxic and as good as standard ethylene glycol
stuff. BUT testing it requires different tools. Mixing it can be fun
though. 50/50 gives you -25 below.
I've used it in my bike and as tire ballast in the tractors. Works
pretty good so far.
Yup, MUCH more (on the order of drinking a half gallon, and even then it
will just make you real sick). Since it is a food ingredient. It is the
ingredient in Mountain Dew soda that gives it that distinctive flavor
(and makes it one of the few sodas that slush up instead of freeze).
It is also used as a dog food and cat food ingredient, namely as a
softener for hard food (makes hard kibble soft like real meat)
and as a flavor enhancer.
