A method of rapidly cooling a high temperature vehicle coolant is disclosed. The method includes determining a coolant temperature lowering entry condition by detecting information on the coolant temperature, an engine speed, and a gear state and determining whether the coolant temperature needs to be rapidly lowered on the basis of the detected information; and changing a number of gear stages by adjusting the number of gear stages of a transmission to be reduced to a specific number of gear stages when the coolant temperature needs to be rapidly lowered in the determining of the coolant temperature lowering entry condition, so that the cooling fan is driven by driving the fan belt through a crank damper pulley using the increased engine speed according to the reducing adjustment of the number of gear stages.
