Technical What coolant do you run?

Check for Voltage, one lead in the coolant the other grounded, anything more then half a volt is no good. It’s checking the coolant for acidity, an acid and dissimilar metals in the cooling system equals a crude battery

 

Used it for years in huge gas compressors . Anti freeze is a chemical solution , it is clear , the difference in brands is anti rust additives . We would buy it in tanker trucks at a time , on cooling tower held 7500 gallons . When purchased , the dealer would ask what color do you want it delivered in .

 

I use house brand green stuff along with a bottle of anti rust in my flatheads with aluminum radiator and water outlets. I add anti rust once a year. Nothing has dissolved yet. On the other hand, these are not fancy high dollar outfits so it makes little difference to me.

 

Let’s hear from someone using Evans……

I looked into it, but haven’t made the change yet on my 348 Chev with about 2500 miles on it; I probably won’t. Here’s what I know so far:

1) It is not compatible with water, so you need to do a flush with their intermediate product first. At Summit Racing it is $31 per gallon.
2) Current price of the coolant is $48 per gallon.
3) It lasts forever.
4) Jay Leno likes it.
