Ok, interesting ill have to do some homework on the additve

 

I run it just to play it safe. I have seen pictures but there wasn't really any evidence to prove it was from the coolant.

 

If your coolant has the right PH and no contaminants such as WATER or any other corrosives that speed up the progress of corrosion their is no need for an additive. the additive will only bring your PH levels to normal and have the correct freezing temp and running temp... FLUSH YOUR COOLANT. bottom line. yes if you have a big Rig then run an additive. That would be a good idea, more cost effective, and if you have not flushed in a while....

 

so are you saying you should run straight coolant with no water?

 

Coolant is supposed to be mixed 50-50 with water. Pure coolant doesn't transfer heat as well as the mix. Look at a lot of the coolant on store shelves and they are selling it premixed for "your convenience". In reality it is so they can increase profits by selling half water at a premium price and make you think you are getting a deal on antifreeze.

 

Distilled water, no contaminants. you can also by 50/50 mix antifreeze. and mix with a bottle or two of regular coolant. then test with a hydrometer and see your freezing point.
-35 below is a good number. then check your Nitrates and PH. Normal PH is 7.

 

just so im on the right path i need distilled water and just regular coolant, and as long as my ph level is 7 which is normal than i should be good??

 

yah you can go that route or get 3 gallons 50/50 mix and two regular antifreeze. and that will put you at about -45 below.

 

alrite cool sounds good, thanks for the help
