Heater Box Replacement - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Is this a tough job?

I discovered it today, I was always loosing coolant, but not enough that it'd overheat, so I filled it up today, and started hunting for my leak, the heater box was dribbling, so I went to tighten the clamp, but I hear a CLUNK from inside, and all the coolant inside of it poured out. So I can only figure I broke the heater box. I've got a spare here.

If not, I'll have to bypass my heater for the trip south...
