Should fan run after shutdown?

Mine never does. Fan is off till it hits 160, and shuts off when I shut the motor off.

The fan should stay on for a few seconds if you shut the car off with the AC controls on COLD (AC ON). Or it should come on when the car is off when the coolant temp is pretty high. On a stock car, I think it comes on in the 195-200plus degree range when car is off. If you have an aftermarket chip it might be diff. Also, if you do have an aftermarket chip, and a 160 degree thermostat.....the engine probably wont hit that high of a temp, so the fan wont need to come on when car is off. I dont think you have any problems. Just try the AC thing to verify that it does work when car is off.

lets say your fan turns on at 178 to start cooling things down so if you shut motor off and temp is above 178 then the fan should stay on after motor shut down to cool the engine otherwise if its under 178 fan will never come on after shut down..

On a stock GN, the fan only stays on after shutdown when it is in high mode. This is that 195-200plus temp I was talking about. If its 175 and the low fan is on, after you shut down, the fan will stay off.
