gilmer belt takes less hp to drive
fan clutch is a must why else do a swap
remember a magnum/ gilmer belt water pump runs backward, different fan and clutch
Mopar actually makes clutches with different temp operating springs
There is a service bulletin for my 92 dakota where they upped the clutch temp 5-10 degrees and went from a 7 blade 3" pitch to a 9 blade 2 1/2 inch pitch to reduce coming on at stoplights and the noise which was like a 747 with the 3" pitch fan
92 was the first year for the magnum and since i had done cooling R&D tests many years ago I knew where to write with comments on the noise of the early Dakota and Ma Mopar listened
Now GM has a 11 blade plastic fan that I want to try
