Make sure engine is cool enough so radiator cap can be safely removed. Shake well. Pour Bar’s Leaks Liquid Aluminum directly into radiator. One bottle treats systems up to 4 gallons. Use 1/2 bottle in 3 and 4 cylinder engines. TIP: If direct access to radiator is not available, install in overflow tank.
Aluminum radiators do not cool better than original types, the only thing aluminum does better is to take weight off the car. Sure they will work, and since they are new they may last longer, but there is nothing better than a recored and restored original, that is my opinion and i am sure others will disagree, but I listen to the experts like Bob at Glen-Ray Radiator who does it for a living.
Benchmark: Copper vs. Aluminum CPU Coolers. Stock testing reveals a measurable (but mostly insignificant) difference of ~0.8C under load and 0.7C idle. The 0.8C delta will show no performance
So a 3-row would be better than a 2-row. Do aluminum radiators rust? Aluminum differs from steel as it doesn’t rust in the same way. It is a reactive metal, therefore, oxidation happens when the metal comes into contact with oxygen. Do aluminum radiators cool better? Yes, they do cool better compared to other materials such as copper or brass.
Why do aluminum radiators cool better than copper units? Copper has better thermal conductive properties than aluminum and that is why many people ask this question. The fact is, older copper radiators are made up of (4) four different materials, not just copper.
