RT would the cheap walley town be the "silicated green coolant" type..do they really sell boiler feedwater there too!! is ur "brew" only "southern" states grade
temp f rated?

Hi Rich, That's what I'm talking about, info from a chief of the black gang! Thanks!!

Funny how I remember that stuff from working in a boat yard. Mercruiser has a tolerance volt reading for their marine motors in a saltwater situation also to prevent electrolytic rot on the alum. parts...dissimilar metals immersed in water produce a current, add some heat & ya got an evil thing happening!

I'm gonna go check if I can find a Wal-Mart, not too many where I live. Does their coolant say "contains silicates"???

I'm not trying to beat a dead horse but Prestone's info line told me their stuff doesn't contain silicates. For all I know the person answering the phone was reading from a MSDS & don't know beans about silicates & LT5's!

Thanks for your insite!
Gingle bells!!

It's my understanding the Wal-Mart "Super Tech" line of coolant is made by Prestone and is the same as their long-life stuff (i.e. very similar/the same to DexCool).

If the coolant says long life or has a 5 year 100+k mile change recommendation, or anything like that, it's a pretty fair bet it isn't a silicated coolant.

i`ve got the supertech jug in my hand. no mention at all about being silicated or change intervals either. says distributed by alsip packaging, inc. alsip, illinois 60656. the water i`m using is pure as pure can be. no minerals either suspended or dissolved. its even deoxygenated and rid of chlorine. silica and calcium is the big thing in boiler feedwater. silica will erode and calcium will scale the tubes under high pressure. no patent on this water. got about 30 gallons in reserve. anybody just drop by and i`ll fix you up. we`re making about 1100 gallons per minute.
