smell of antifreeze
Anyone ever had a problem with a leak in the coolant side of a 5.2L. I am always getting a slight smell of antifreeze from my truck inside and outside of it. Its that sweet smell so im almost positive its antifreeze. I cant see any leaks any where and my level does go down slightly but nothing major.

They are common so seep a bit of coolant around the thermostat housing and upper rad hose. look for some black/green goo in that area. Also look where the radiator core meets the plastic end caps for same seepage

I think your heater core is on the way out, that's the only reason I think you'd smell it in the cabin.

That sounds like what was going on with my truck... My post describes where I found mine leaking...

And on a little more positive note: Usually when the heatercore starts to leak it will leave a slimy film on the inside of the windshield when you put it on defrost. A down and dirty way to check if it is your heater core is to clamp off both heater hoses and see if your antifreeze stops disappearing.

Speaking of which -- how do I locate the drain for the radiator core box on the outside?

It's the same as the a/c drain. Below the PCM on the pass. side firewall.
