Why Choose the Lizixny Metal Heater Hose Connector?The heater hose connector is a critical component of your vehicle's cooling system, responsible for diverting coolant to the heater core. On many Chevrolet, Cadillac, and GMC trucks/SUVs (2000-2014), the original plastic fitting (OE #15055342, 15055343) is a common failure point.The Problem with Plastic: Over time, constant exposure to high heat and pressure makes plastic brittle. It often cracks or shatters, leading to sudden coolant loss, engine overheating, and potential breakdowns.The Lizixny Metal Solution:Unbreakable Construction: Made from robust metal to withstand high temperatures and thermal expansion.Precision Engineering: Manufactured to meet or exceed OEM standards for a hassle-free plug-and-play installation.Corrosion Resistant: The silver metallic finish resists rust and degradation from modern coolants.Complete Seal: Premium NBR O-rings provide leak-proof performance.Package Includes:1x 800-414HP Heater Hose Connector1x 800-413HP Heater Hose Connector2x Assembly Grease (for easier installation)Installation Tip:Allow engine to cool completelyDrain coolant to below the hose levelRemove the old plastic tee (it often breaks during removal—this is normal)Clean the hose ends thoroughlyApply the included grease to the O-ringsPush the new metal connector into place until you hear/feel it clickFitment Highlights:2002-2014 for Cadillac Escalade/ESV/EXT2007-2013 for Chevrolet Avalanche2000-2014 for Chevrolet Suburban/Tahoe2001-2014 for Chevrolet Silverado/GMC Sierra2000-2014 for GMC Yukon/Yukon XLPart Cross-Reference:Replaces: 800-414HP, 800-413HP | Supersedes: 800-414, 800-413 | Interchange: 15055342, 15055343Warranty: Backed by Lizixny's 1-Year Manufacturer Warranty.Seller Support: If you have any question, please feel free to contact us.
