Using prestone as additive?

[Charloz24]

I forgot to buy HydrX in my recent order for my new watercooling setup. Problem is, I have the time this week to do the build so was wondering if prestone used in diesel engine could do the trick?

[Soultribunal]

I'm pretty sure you could but I would not reccomend it.

They although sound similar do have some differences in composition. Espically the newest formulations in order to keep in compliance with stricter Coolant standards.

as a test,sure. longterm it might eat up tubing, maybe

it may work but may not be as effichent !!

[gingerbee]

it works fine i am just not sure of the mix you'll have to do your own research it has been a long time since i did this.

Distill water is always the best option. :D

I would suggest premixed antifreeze. It'a available almost anywhere and you won't have to worry about water to coolant ratio. You might even consider diluting it a little.

[astrodanco]

So far as I know, you only need to add antifreeze to your coolant if you have mixed metals or sub-zero coolant temperature in your loop. Otherwise it's not a good idea and will hurt your cooling performance.

it will not cool as good as water? true but with out ethylene glycol is will grow things. you can just use iodine or silver too ah. not a good idea it's in almost all cooling you mix it with distilled water in computers.

Glycol-based substances have worse thermal characteristics than water, so they won't help your cooling any, and they keep changing formulations these days, so while there probably won't be any problems, it's not a 100% thing, especially where the seals are concerned. Your best bet is to use Distilled and find a copper-based biocide (at an aquarium store, perhaps), as I've seen long-term complications where iodine-based biocides mix with copper.
