to have the coolant running constantly, and not having to wait for the engine to reach a certain temp for the thermostat to open. only downfall is that it takes a little longer to get your engine to the operating temp. nothing to big though.
yeah I figured out it was a faulty clamp for the hose that leaked the coolant out, and it being so hot out, it evaporated the coolant real quick so I didn't notice that it had leaked. haha
