#122942 hi guys

im having a problem with the cooling fan coming in.
it is a b18c4 engine and i changed the coolant, bled the system properly and now the fan is not kicking in. I am getting hot air inside the car, i have changed the thermostat and fan switch but it is still not working.

The top and bottom rad hoses get really HOT, then i have to manually jump the fan switch to kick the fan in, once i leave the fan on for 2-3 mins or so the bottom pipe gets cool.
Then i plug the wire back in and still no fan.

Any help is appreciated

thanks guys
