i recently put an underdrive pulley on my 3.0. 99 flex fuel. it's 2 inches smaller (belt went from 88 to 86 5/8). is this going to hurt my accessories such as water pump, alt. etc...? below is the pic of the two pulleys.

 

i'd like to add that i have the 5.0 radiator in my ranger, so coolant capacity isnt a problem
