Ok, I have a non-tractor question for you. I"m having issues with my Impala. There is radiator fluid leaking from some type of orifice (I don"t know what it is on top of the fan shroud/radiator right next to the radiator cap. The radiator cap was replaced this summer.

I only use the green antifreeze and the car has 253k miles on it. The car doesn"t overheat at all I just can"t figure out what"s wrong with it. My buddies at work don"t know what its leaking out of. I do have the 3.4 engine in it...is it the head gasket leak?

Sounds like it"s time for a new radiator.
