Engine cooling systems are only as good as their sum of total parts, radiator, water pump, hoses, clips and water joints are just a few essential parts that if not perfect can loose coolant and/or cause the engine to overheat. If in doubt, simply replace the suspect parts, preferably with new fasteners and clamps, which will look so much more professional from an aesthetic view point?
