Yes, it should. The CEL will come on as well.On the 89 Daytona's does the fan turn on if you unplug the coolant temp sensor?
No.Is the fan supposed to stay running when the car is OFF until the temp goes down?
At speeds over 35 mph the ram air effect should be more than ample to provide the needed cooling (heat transfer). The fan is needed at lower speeds. May want to check the rekay as well. Swap relays to check. May need a new cap (16 lbs) as well - they are usually pretty cheap.
