CRX doesn't have temp sensor in the radiator - the temp sensor/cooling fan switch is on the back of the block next to the oil filter - 2-wire connector with big black rubber boot - disconnect the 2 wires and connect them together - with ignition on, the fan should come on - if it doesn't, the cooling fan switch is bad or you have something messed up in the wiring
