Both fans in my RSX Type S do not turn on. Once the car gets warmed up and the temp starts rising the coolant starts to bubble out of the small plastic tip on the top of the reservoir. I want to check the temp sensor but can’t find it. Is it at the bottom of the radiator?



Thanks!

BTW, I have a 2006 RSX Type S 6 speed Manual Transmission

You should first verify that your thermostat is opening before going to swap out the fan switch.
The temp sensor is in the head, not the rad.
The OP states he has coolant bubling out of the resevoir when the temperature rises but the fans do not turn on. The fans are contrioled by the ECU and the fan switch at the bottom of the radiator. which he tested, but the fans still didn't turn on. So either the fans are both defective or there is no power getting to the fans. He doesn't say he has any trouble with the temperature sensor which, yes, is in the head.

OP, the switch grounds the fan circuit. Did you try applying power and ground directly to the fan motors to test them?
