The Dorman OE FIX 47157 replaces the fragile plastic piece with a stronger aluminum junction and includes hose clamps so you can complete the repair without buying a whole new hose assembly. That saves money, reduces waste and restores a secure coolant connection to your engine’s cooling system.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this aluminum junction differ from the original plastic connector?\u003c\/h3\u003e\n\u003cp\u003eThe Dorman 47157 uses corrosion-resistant aluminum in place of the stock plastic, which improves durability under high-temperature and pressure conditions. Aluminum resists the cracking and deformation that often cause plastic junctions to fail, and the part is machined to match factory dimensions for a reliable fit.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eConstructed from aluminum for enhanced temperature resistance\u003c\/li\u003e\n  \u003cli\u003ePrecision-machined to align with OEM mounting and hose diameters\u003c\/li\u003e\n  \u003cli\u003eIncludes clamps to replicate a complete connector installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this part fit my Cadillac, Chevrolet or GMC vehicle?\u003c\/h3\u003e\n\u003cp\u003eDorman provides this junction to fit specific makes, models and years — it’s essential to confirm compatibility before purchasing.
