How do you change the radiator of a 4 cylinder 1993 Toyota Camry?

Should be drain plug on engine side of radiator down towards the passenger side. Drain fluid and dispose of properly. There is no easy way, remove hoses connected to the radiator at the radiator and electrical fan housing this should have a wire connecting plug. You will not have to take off the front of the car. just work your way from the hoses to the radiator. If you feel that you will have problem remembering where things go use masking tape and marker to label. Example take two pieces of tape and write # 1 on each place one on the item your removing and the other on the spot where you removed it from.
