If there is no bleed valve then the best way is to either jack up under the frame on the side where the radiator cap is until the radiator filler neck is higher than the rest of the cooling system which includes the heater core.
Or just pull that side up onto a curb. Then remove the radiator cap, top off the coolant, place a drain pan under the filler, start the engine, place the heater on hot, leave the blower fan off, rev the engine to 1,500 to 2,000 rpm's until the thermostat opens. Then top off the coolant if need be. Then while the engine is idling, grab the top radiator hose in both hands push down as far as it will go without pushing it into anything moving, like the fan, then squeeze real hard with both hands on the hose and push any air out the radiator filler neck, top off coolant again, replace cap, shut off engine and/or lower vehicle to ground.
If though there is a degas bottle, they are supposed to bleed the system themselves.
