Strong antifreeze smell - The 1947 - Present Chevrolet & GMC Truck Message Board Network

After I drive for ten minutes or so, I get a smell of antifreeze inside the cab. If I turn the truck off for a few minutes, when I start it back up, the smell is the strongest. I can't see anywhere that it is leaking; there's never a puddle; no smoke from the exhaust; nothing dripping inside from the heater core. It doesn't seem to matter whether the heater is on or off.
Any thoughts?

Can I just bypass the heater core by connecting the two hoses together or removing them all together and plugging the holes?

Sure. And if the smell goes away,you know it's the heater core OR just one of the hoses inside the cab,maybe even a loose clamp.
