Engine cooling systems are only as good as their sum of total parts, radiator, hoses, clips, cooling fan assembly and water joints; if in doubt, simply replace, preferably with new fasteners and clamps, which will look so much nicer than reusing the old items.
TIP: After you have refurbished the cooling system, be sure to use only factory recommended coolant.
