For us hot rodders, weight is bad. So ditching the copper brass radiator for an aluminum model is a no brainer. There are many old wives tales about why aluminum radiators cool better. The most common one is ‘aluminum dissipates heat faster than copper Passing the coolant through one-half of the radiator twice doubles the coolant speed and its pressure. However, since a double pass radiator reduces the volume of water that passes through the core in half, its pressure also doubles. The increase in pressure in the cooling system is where the cooling benefits emerge. Coolant composition. A 50/50 mixture does not help cooling it raises the boiling point. Run 100% distilled water with water pump lubricant or distilled water with about 15-20 % antifreeze. Both cool better than 50/50 and still lubricate the water pump to prevent corrosion in system. When the weather cools return to 50/50. Area = 228.05" 2. Now, for comparison, use the formula below to calculate the surface area of your radiator's core.

Mine it leaking on the top where the plastic tank is crimped to the aluminum core. The mishimoto is a stock size an all aluminum. Which would b stronger an might cool a lil better bc the tanks can release heat better than the plastic ones on the stock radiator. Reply Like. 9SWyo.
