I will assume you are trying to flush the cooling system. First, go buy a radiator cap. Then, the treatment liquid is poured into the radiator via the cap opening. Once it is in, put the cap on and let the car come up to temp (unless the fluid container you bought says different). After following directions on the bottle, you will drain the cooling system and fill back with a 50/50 water to antifreeze mixture and secure the cap. THIS IS FOR RADIATOR TREATMENT - NOT ENGINE OIL OR ANY OTHER FLUID!!!
