The plastic heater hose t-piece found in the Ford Falcon BA-BF and FG Barra engine is notorious for breaking down and causing engine coolant leaks. This is due to the brittle nature of the plastic over time breaking down. Being a discontinued item from Ford, Aeroflow Performance has made a new billet aluminium version to combat this problem. Made from billet 6061 aluminium and black anodised for corrosion protection. Both inlet barb fittings are 3/4" with a 3/8" barb and 5/8" barb are included to choose which model you have to suit on the side of the tee piece.
