Leaking coolant on underside of throttle body. I thought I had a bad head gasket due to the smell but upon closer inspection, most of the smell was coming from the engine compartment. It is leaking onto the drive side exhaust manifold.
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.
