aluminum radiator

I was wanting to know what's the best kind of antifreeze use in a alum radiator

[70769 18]

I dont know about the best. But I use late model Nissan green stuff I had easy access to it. I figured id work well. And it has.

Thanks for info, where can you get it, and is it a 50/50 mix

Distilled Water combined with Dex Cool is what I use...if you add water use only distilled water...walmart has it for .89 cents a gallon.

If you dont have to worry about freezing you Really don't see much benefit from anti-Freeze

Thanks for the info, yeah I live in indiana so I have to worry about the freeze

I would use Evans Waterless Coolant. It is non corrosive, environmentally friendly, doesn't freeze, and has a boiling point over 300*. It is expensive, but it also will last the life of the car. This episode of Jay Leno's Garage talks all about it.

MustangBobby,Thanks a bunch for the info and the vid, sounds like a good way to go, do you use it? Is it as good as they say?

[MustangBobby 28]

I will be shortly, and Jay Leno's word is good for me.

You can get it from any nissan dealer. It was not premix, I just added water from our water cooler and called it a day. Haha

Any antifreeze that meets today's automotive standards will be fine.

 

Prestone's off the shelf coolant meets the Dex Cool specification, and it comes in 50/50.

Thanks to all of the relies, a lot of good info

[barnett468 418]

i would put a sacraficial anode in it to reduce electrolosis

 

waterless anti freeze may not cool it very well. but if you don't run hot then it is ok.

Choosing the right anti-freeze can be a real pain, quality wise and system compatible wise. Not as simple as just throw in the green stuff anymore. Now it's is it green, pink, orange or yellow, brass or aluminum rad, water pump type etc ? But lucky for you we're not talking about a newer model car. If you chose Dexcool, do some research first. With some friends that work at a GM dealer I hear some good stories. Also you need to use it right from the get go or it's a bunch of work and money to get a system ready for it. Yes choose an anti-freeze that is pre-mixed as its usually not the anti-freeze that fails it's the water that is used to dilute it or yes use distilled water ( though it irks me that you pay just as much for diluted as for concentrated, but that's what you get for convenience and distilled water). If I was to use something that's readily available it would probably be Prime from Prestone or Peak.
