I have a radiator without a radiator cap reservoir, and I am stumped on how to fill it with coolant after flushing the system and replacing some hoses and the fan.

Again I just need to know how to fill the radiator with coolant when it has no radiator cap to poor into.

The expansion tank is the white plastic tank with a black cap. Open the bleed screw at the top of the Tstat housing to let the air out when filling.
