Now look at aluminum radiators. Why do they cool better? Aluminum allows us to run significantly higher water pressure levels than brass. A brass radiator should be using a 6-8 lb cap to eliminate radiator damage. An aluminum radiator will run a 11-17 lb cap. Double the water pressure and you reduce water temperature.



So aluminum radiators cool better because they can run higher cooling system pressure? Funny, I thought it was because they have a higher fin count that they cooled better. A 6-8 psi cap seems too low to me for a brass radiator. I use a 15 psi cap on my 4-row brass radiator with no problems.
