I have had this issue for a while now, it all started approximately two months ago when my thermostat gauge would elevate to hot on idle but would decrease in motion. The radiator finally ruptured approximately a week ago and I had the thermostat, radiator, upper/lower hose replaced. After driving it for 4 days my car began to overheat, when I opened the hood antifreeze was all over the place. I checked the radiator cap and the pressure was good, I checked the hose and none were ruptured, I removed and replaced the thermostat and ect sensor because my thermostat hose was cold and now it is hot but my car is still overheating.I noticed my radiator fan was not moving so I replaced the #17 on under dash fuse/relay box and 56 under hood fuse/relay box per service manual and still the radiator fan does not work, can you provide with a little guidance on what the problem may be?

First of all thank you so much for your donation. If you can tell me which model civic you have engine size and if you have a/c I can get you the correct information for the fan.

I emailed you a radiator cooling fan wire diagram also where your radiator cooling fan relay is. You said you checked your fuse 56 in your under hood fuse box that fuse is for your a/c condensor fan motor you need to check fuse 57 in the under hood fuse that's the fuse for your cooling fan motor.I hope you have a multimeter and know how to use it because you will need one for these next step's. Go to your radiator cooling fan and make sure you have a good ground to the black wire going to the motor. Now go to the cooling fan relay with the key in the run position the black and yellow wire should have battery voltage going to it. Now ground the green wire going to the cooling fan relay the fan should come on. If it doesn't then see if the black and red wire to the cooling fan relay has power to it while the green wire to the relay is grounded. If it does then see if you have power to the black and red wire at the cooling fan motor while the green wire to relay is still grounded. If it has power and the motor then check the black wire for a good ground to the motor if you have power and ground to motor and the motor doesn't come on then bad motor.
