Is there any way for me to test my radiatoar flow? I have been having an aver heating problem for a little while so I took my thermo out so I could run it for now until I figure what's wrong. Well the funny thing is that even with no thermo it still gets warm, no where near where it should but it is not dead flat cold either. If I have to sit with it running for a few min it heats up too (even without the thermo). I have changed the water pump too. Anyone have any ideas other than the radiator?
