Out driving the 2002 Silverado this evening (6.0 engine) when the belt started squeaking, so I took it easy the rest of the way home. When we got out something smelled odd, then we heard dripping. I looked under the truck and coolant was dripping everywhere! What? I tried to track down the source, all hoses look to be attached, radiator appears good, overflow tank is good. Where is this coolant coming from? If it makes any difference the overflow tank is completely empty of coolant. Thankfully we were almost home and the engine did not overheat at all.
