Today i swapped over all OEM radiator pipe work to corksport silicone.
Ran car to operating temp to open thermostat and turned both dials on heater to max 32deg, turned fan to max.
drained radiator into bucket and measured used fluid (close to 5 litres) only.Mazda spec is cooling system holds (7.5 lires)???????
Car was jacked up ,so maybe fluids still in water jacket and heater tank.
All new pipes fitted ,so filled system with clean demineralised water (5 litres) and lowered car ,ran engine 15 minutes to burp air and squeezed hoses, then drained all fluids again to flush system.
Again only 5 litres ,but full of green fluid.
Refilled system with fresh coolant.(5litres only) ??????? whats wrong ?????? it should have taken 7.5 litres as spec.??????
Any advice ,Thanks.
