Engine Cooling problem
1993 Mazda Navajo 6 cyl Four Wheel Drive Manual 194xxx miles

my temperature gauge in my car goes from hot to cold. It sometimes blows cold air when I turn on the heater. I have replaced the thermostat and filled up the coolant making sure there is no air in the engine. What else could be making it do this?

Ensure radiator fan(s) come on properly and flush coolant system as there could be partial clog in system
