Weak cooling, oily residue around the hose fittings or a visibly damaged hose can mean this hose is worn, though a leaking condenser or a failing compressor can be behind the same signs, so find the cause before you replace it.
It fits the 1999-2005 Chevrolet Astro V6 4.3L and the 1999-2005 GMC Safari V6 4.3L.
