Only clean your radiator if the engine is overheating.
If the tap on the side of the engine is blocked then remove it and clean it out. Attach a hose to the heater tap and run water though it wih the tap open to clear the sediment out of the block.
To clean the radiator you need to drain it and remove it from the car. Shake it to loosen any crud in it then flush it out with a hose in the top and bottom of the rad. If the capillery tubes are blocked this may not clear them and the radiator will need to be professionally pressure cleaned or need a new core.

Try the hose pipe if you like - but DO NOT run the engine while doing this...... Probably need to remove the side tap (carefully) and then probe inside the block with a piece of wire. beware - removing the bottom hose will probably ruin it - so don't do this unless you have a new one ready to fit. Unless the engine is overheating - I do suggest you leave it all well alone!
