Had coolant leak numerous times starting back in 2007 around 126,000 miles, again in 2009, 2010 and now currently 2013. I have had the intake manifold gasket sets replaced twice. My water pump, radiator, thermostat and even the radiator cap at least once. I'm sick of smelling coolant for more than 5 years and each time I'm told its something different. Now besides a new water pump needed, leaks may be coming from intake water outlet amd coolant pipes under intake. After repairs this year, I will have spend close to $3000.00 in repairs for coolant leaks (especially gaskets). Parts are cheap, but labors not.
