Sweat at sealing areas, usually white grey or green grey depending on coolant color, does not justify the replacement of the coolant pump, cylinder head gasket or coolant hoses.
A small leak from the breather hole of the coolant pump during the first approximately 1,000 miles of vehicle operation is normal.
The coolant pump only needs replacement if there is a noticeable leak like coolant on the garage floor or coolant level drops below minimum mark with a cold engine.
