rad fans not working - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I hate starting this thread, but I have searched and read about it for a while and can not find the answer.

My radiator fan is not kicking on. I am not a smart cookie though... I looked at the fan with the ac on after start up and it did not move. It overheats going down the road (or standstill) and doesnt kick on either.

How do I check to see if it is the fan or the relays?

I just moved and have limited tools so I am worried as it is my daily driver.

Any help is greatly appreciated.

use two wires to directly contact the fan plug with the battery, if it comes on, you have a good fan and something else along the line is bad.

I feel dumb er.
It was unplugged. Happened going down the road somehow as I never touched it

Car got a lil hot now and again, but not outside the 'ok' brackets on the gauge.
But it made a ton of noise after it was shut off as it was dropping a large amount of coolant into the reservoir
I opened the radiator cap to find it was low. Why would it be filling the reservoir if the rad is low?
