2001 mazda MPV overheating
Van keeps overheating I've replaced the thermostat, the water pump, and the whole coolant overflow tank. I don't seem to have any leaks and I ran a blue devil treatment in it but when my mechanic did it he flushed the radiator but not the motor. Also my heat isn't working now and I just replaced the thermostat with a fail safe thermostat. I don't know what to do I've sunk so much into the van. Please help thank you so much
