1995 Pontiac Grand Prix Question: Replacing radiator hose
Answer #1patrick mannion from Greg Solow's Engine Room, September 23, 2010, 19:26Master
The leak may be a hose or a leak from the radiator itself. The way an automotive shop would locate the leak is by removing the radiator cap and attaching an adapter that screws on in place of the radiator cap. Something that looks like a bicycle pump with a pressure gauge attached to it is used to "pump up" pressure to simulate pressure generated when the cooling system is at operating temperature, the leak is then found sometimes it is obviously leaking from a coolant hose or cracked housing, failed gasket or water pump, sometimes the engines cooling system needs to be inspected from below or inspected using a mirror and flash light.
To replace the radiator itself is 1.5 hours labor and $170 to $300 in parts depending on where the radiator is sourced from.
Probably .8 hour to replace the top hose, $30 for the hose $18 for coolant.
