Where is the over flow jug hook up to the radiator on a 1997 Chevrolet Blazer?

On a 1997 Chevrolet Blazer, the overflow jug connects to the radiator through a small hose that typically attaches to the radiator's overflow or filler neck. This hose allows coolant to flow from the radiator to the overflow reservoir when the engine is hot and the coolant expands. When the engine cools down, it creates a vacuum that draws coolant back into the radiator from the overflow jug. Make sure to check the connections for any signs of leaks or damage.
