Keep coolant moving between your engine and heater core with the SKP Heater Hose Connector, MPN SK800409. It is designed as a direct replacement for the existing connector on applications including the 1999-2014 Chevrolet Silverado 1500, the 1999-2014 GMC Sierra 1500, the 2002-2005 Ford Excursion and the 2003-2014 Cadillac Escalade ESV.

This coolant connector works on the inlet/outlet side of the heater circuit and joins a 3/4 in. tube to a 5/8 in. hose. It is cataloged for the heater-to-engine and engine-to-heater positions. As an HVAC heater hose connector, it carries coolant between the engine and the heater core so the heater can work properly.
- Built to OE standards: Made to OE specifications for quality, a secure fit and proper function within the heater core system.
- Leak-free connection: Designed to give coolant a leak-free connection on its way to and from the heater core.
- Durable build: Made from materials intended to resist wear and tear for dependable service.
- Direct replacement: Installs in place of your existing connector, which can simplify the repair on some vehicles.
Signs this part may need replacing: coolant seeping or dripping at the heater hose connection, a cracked or broken connector, or reduced heat from the vents. If a failed connector is the cause, this SKP replacement is intended to restore proper coolant flow to the heater core.
