If you have a coolant reservoir do this.

there should be a mark in the coolant reservoir, just fill it up to there and let it run for a few mins then open it back up and pour more in until its up to the line again... at least i think thats how u do it.
Many older vehicles don't I'm not familiar with pre 90's rangers personally so i don't know, but if there is no reservoir follow mahnini's advise.

just fill it till it's full. start the engine but keep the radiator cap off and it'll drain slowly and you just keep filling. don't think it'll overfill, either way i'm sure it has a mechanism to spit out excess coolant.
