What's the best Radiator Flluid

I had to replace my radiator. Got a factory Johnson Control unit which is a FoMo company for 150.oo. So what is the best flulid to put back in the system- Green or Orange? The radiator shop said green, I think they just were not sold on the orange Dexotex stuff. BTW if anybody needs a radiator go to Otani Radiator Service in Montebello California. It was even cheaper than 5 Star. They said that FoMo released the mold of this unit and the price dropped from the dealer list of 325.oo to whatever.

Exclamation Not Sure...

...as to what's the best, but here's some tech info about the Dexcool fluid:

Seems it was formulated as a longer-life fluid that GM has been using.

I use Peak. I figure if you flush it when needed, it really doesn't matter what brand you buy.

I sorta agree with Jack, I think it doesn't matter what brand, but be consistent.

Also use water wetter, and 50/50 for cold climates, 80/20 for warm climates.

Stick with the green stuff for our cars. Dexcool is for the new gm cars. I use prestone in a 50/50 mix with distilled water. And a bottle of redline waterwetter for good measure (the stuff works great)

Smile My opinion...

Roy,

I run a mix of 50/50 distilled water and green anti-freeze from Prestone in the engine coolant system. Have been for years and it works great. I also use a 180 t-stat. For the I/C system, I run a mix of 70/30 distilled water and Dexcool orange coolant. I also use a little water wetter in the mix. The simple color difference between fluids can help you solve a leak issue later on.

I would NEVER run Dexcool in the engine, but that's just me. Even the I/C likes to crystalize from time to time.

Atrain,

Good idea using different colored fluids in the different cooling systems. That really makes sense. Very easy to tell what system is leaking.
