This procedure makes a bit of a mess and requires catch pans but it is the best way to flush a coolant system without cutting any hoses or adding a flush kit.
If your radiator does not have a drain plug is to remove the LARGE lower radiator hose and drain the anit-freeze. (Even if it does have a drain plug the steps below are the best way) You then plug the lower radiator hose connection on the radiator and have a 2nd person add water to the radiator with a hose. They will need to place a rag over the fill port for the radiator and flush the block until you get clear water from the lower drain hose. Once you get clear water drain off the fresh water by unblocking the lower radiator fitting and flush the radiator. Once you get cleanwater from the radiator connection, reconnect your lower radiator hose. (Tighten the clamp!) Then add your anti-freeze. Remember there will still be a some water in the block so do not be afraid to keep your anit-freeze / water ratio a tad higher because the left over water in the block will dilute it slightly.
at the bottem on the left or the side there is a small key like screw ( righty tighty lefty lucy } then u must remove the radiator cap and also remove the themastate be sure to attach the therma housing and hose and unatch it at the top of the radiator the put water hose in the open cap area and flush for 20 mins turn on engine and let run for 2 min and repeat flushing untill all antifrez desapears. be sure to put every back tack pitchures as you remove so to put back the same way it might be good to get new thermastate
Things you will need:
Radiator coolant mixture (get from garage)
Radiator flush fluid (also from garage)
Distilled water (Or if your me garden hose water ;) )
Take off the radiator cap when engine is COOL. Find the drain plug located in the bottom of the radiator (normaly hand tight) and let it drain out into a catch container. Put the drain plug back in, follow the instructions on the flush container topping the radiator back up. Let engine run as directed on bottle and then carefuly undo the radiator cap using a rag as not to burn yourself. Then remove the plug again and drain out the flush fluid. Then repeat the process with the radiator fluid as instructed on the bottle.
Initially, on most cars, the radiator drain plug is located at the lowest most section, often to one side. It could be a wingnut type or a regular bolt or squarish variety. In some instances it would be pretty difficulty to locate nor access due to the other coverings and components of the front end of the vehicle.
Alternately, removing the lower hose radiator side would serve the same purpose.
Good luck and Thank you for using FixYa. Happy Holidays.
