I filled fluid, and the fans seems to turn on fine, but the temp light keeps coming on after 15-20 minutes.

Any idea's?

Is the thermostat working ??, would be the first thing to check or possibly the water pump is faulty & needs replacing ??
Hope this helps.

Air in the system. Did you "bleed" it after filling?
