I just bought '90 N/A RX7. I plan to do a rebuild after troubleshooting problems I've encountered.

First, my temp gauge does NOT go past normal operating temp (stays in middle). Add Coolant light comes on, then goes away. I noticed the overflow reservoir tank gets full after a day of driving doing errands. I replacedthe thermostat tthat opens at 180 degrees Fahrenheit. The radiator is an unknown aluminium aftermarket with no bleedplug lIKe OEM
