90' civic std hb. my question is which switch controlls the radiator fan. if you are standing at the passenger wheel staring at the distributor side of the motor, on the right hand side of the distributor (radiator side) is a coolant sensor that has two pin plug in, then there is the one that is under the distributor to the left of the other sensor that has a one wire connector, which of these operates the radiator fan? also, any way to easily cheat to jumper anything to test out my fan as well?

thanks guys

 

the 2 pin sensor is the TW sensor for the ECU - the 1 pin sensor is for the temp gauge - the cooling fan switch/sensor is located on the back of the block, next to the oil filter (also 2 pin)

 

gotcha.............bet it is fun to get too!

 

is this the same with a d16z6 cause my fan ain't turning on?
