Hey guys so I'm having problems with my 94 gt overheating and found that the electric radiator fan isn't working but when I hooked up my scanner to test the fan will run through the tests just fine low speed and high speed I've cleaned the connections I've traced wires to make sure there is no bare wires I'm at a loss I can't seem to figure it out I thought maybe fan clutch? But why would it work when testing but not when the car is running? I'm at a total loss any help would be great thanks guys

 

And now I have no hot air when I turn my heater on

 

sounds like the coolant level is low if you have no heat also. and that can make the fan not come on also. Electric fans dont have a fan clutch either. just a heads up.

 

yep... i would be checking coolant level as well. An air pocket in the cooling system will cause overheating and incorrect readings by the ECT sensor.

 

Ok well that makes sense then because I just filled all my fluids including antifreeze so maybe I got an air pocket somewhere what do you recommend doing to fix it?

 

Could over filling it cause this?

 

Before I respond... I want you to think about that for a second.



If you overfill your cooling system, it spills on the floor. Full is full, not full means you have air in the system. over full means you spilled.

 

I mean I get that but I didn't know if maybe there was like a pocket that could have trapped air or somethin

 

Top off your coolant, leaving the radiator cap off, start car and let it idle till the thermostat opens. You might see the level drop then. Give the motor a couple quick revs. Top off coolant, put radiator cap back on and drive the car normally for 15 min. Keeping an eye on temps. Check level again when you get back home, top off again. Done.....

Keep and eye on temps and level for the first couple trips.

 

Ok I'll give that a try thank you
