The book says it holds 7.5 liters. after draining, only 4 liters came out. when filling back up only 2.5 liters went back in. Is the engine suppose to run a bit or sumtin to circulate the new coolant in order to add more?
 
you are supposed to run your car to let it get worm so the thermostat warms up. than all the fluids from the block will come out too cause the therm. will be open
