To shorten the time needed to analyze a temperature of a coolant.SOLUTION: A coolant temperature analysis method comprises: a pre-analysis process of calculating a flow of a gas at a periphery of a heat exchanger 3 exchanging heat between a coolant and the gas; a specifying process of specifying, based upon an analysis result of the pre-analysis process, a rate α of a gas flowing around to pass through the heat exchanger 3 again after passing through the heat exchanger 3; and a main analysis process of using the ratio α specified in the specifying process to predict a temperature Tc of the gas before passage of the heat exchanger 3, and also using the predicted temperature Tc of the gas to calculate a temperature of the coolant through linear CAE analysis.SELECTED DRAWING: Figure 1
