When my car was restored, the restorer modified the radiator so that it's now a "full flow" radiator. The inner baffle was removed and now there's an inlet on one tank and an outlet on the other. Now, the water flows from one side to the other like most normal radiators, rather than flowing through half the radiator, turning around and flowing through the other half.
I was told this was the more efficient way to do it because in the stock dual pass configuration, the hot water from the first pass heats up the water from the second pass and makes the radiator less efficient at dumping heat.
Is this true???
