Abstract: A radiator core support structure comprises a radiator core support and a heat exchanger. The former has a through-hole, and a fixing hole on its the lower portion. The latter has a pipe projecting rearward and introduceable in the through-hole and a lower mounting pin projecting downward from its bottom portion. The fixing hole is formed as an elongate hole extending toward the front side so that the pipe can be kept free from an interference between the pipe and the radiator core support when the lower mounting pin is inserted in a front side of the fixing hole and the heat exchanger is turned rearward around the front side of the fixing hole to stand erect. Then, the fixing hole allows the mounting pin to be slid rearward for introducing the pipe through the through-hole.

Abstract: A connecting structure for connecting a radiator having a reinforcement member and a condenser having a bracket is provided. The structure includes a connecting member having a spacer portion and a holding portion integrally formed on opposite sides of a notch. The spacer portion is fittingly inserted into the reinforcement member, and a folded portion of the reinforcement member and the condenser bracket are inserted into the notch. A bolt is inserted through the reinforcement member, the spacer portion, the bracket and the holding portion and a nut is screwed onto a tip of the bolt for clamping the radiator and the condenser together.
