Cooling systems arevery important, yet easily overlooked. To flush out, just undo hoses at the clamps closer to the radiator.
Next undo surround off radiator. Next undo mounting bolts of radiator. Once radiator is loose, remove radiator.
Now get garden hose and turn tap on at a steady flow without a hose attachment ( no nozzles etc). To begin flushing radiator, remove radiator cap and turn radiator upside down onto clean pathway/driveway. Place hose in bottom (now at top) outlet and let water flow through.
The reason you turn upside is to let any crap fall out instead of jamming further in the tubes. If happy that you have clean water now, lay radiator down and check for foriegn material in top tank. If clear just run water through from top for quick double check clean.
No don't put in radiator yet. Take hose over to motor and place in top hose and flush motor until clean water appears. Now reinstall radiator and fill with quality coolant. ( I recommend buying from radiator shop, or , Castoral Concentrate and mix to instructions. Don't penny pinch and buy cheap ready made coolant. TROUBLE IN A BOTTLE!
