Question about 1987 Mazda RX-7
Make sure you use new coolant with this process. Dexcool is recommneded only Because the maintanance Interval is more than 100k miles.
Are the fans Switching on when the vehicle reaches Operating tempurature?
Do you use Higher viscosity oil for the engine, and allow for the trubo to cool off after hard runs?
Did you install the Thermostat correctly.
Most likely it might be the Coolant, Do not use pure water for cooling. It will evaperate eventaully even with a hihger psi radiator cap.
