Radiator Wetting Additives

[Tham]

Might anyone have some feedback on one of

these cooling system wetting additives ?

 

I'm hoping to help the radiator cool down more efficiently to

reduce the operating time of the thermostatically switched

electric fan, thereby improving its lifespan.

I was thinking of adding Redline's "Water Wetter",

Justice Brother's "Radiator Cooler" or DEI's

"Radiator Relief", until I read in the links below

that wetting agents might soften gaskets and

water pump seals, leading to leaks or pump failure.

 

One guy mentions in the first link that he used to run

Dexcool with Water Wetter, until his pump went

out at 17,000 miles.

Redline water wetter, used to use in performance applications at a previous workshop, don't use it with anything other then straight distilled water as it is already a corrosion inhibitor, I think you will find that the guy in bold overdosed on inhibitors which is why his seals did not last, you will also see that he just uses dist. water with water wetter now.

 

Hope this help.

Thanks for the good info.

 

I didn't realize that corrosion inhibitors wears out

rubber seals.

 

I've added just 500 ml of "Enoch" (a United Arab

Emirates brand) green coolant, which is 30%

ethylene glycol, to only the expansion tank,

none to the radiator, which has distilled water.

 

This works out just about 10% coolant : 90% water,

but maybe even this is too much.

 

I better drain it out and switch over to pure distilled

water before using any wetting agent.
