I flushed all my coolant out and put the thermostat back in and put all the hoses back right, but I can only get 3 quarts of coolant back in. I've drove the car and also let it set, but I cant get the fans to cut on and it doesnt seem like the thermostat is opening. Any ideas?

 

nevermind, it just took it forever for it to get hot enough to open and cut the fans on
