Gates 18132 HVAC Heater Hose - Throttle Body To Pipe-1 or Throttle Body To Thermostat

Gates Molded Heater Hose for Tight Engine Bays

The Gates Molded Heater Hose, part number 18132, is a factory-molded coolant hose built for compact engine layouts where a straight hose will not route correctly. It is made from EPDM and measures 8 inches centerline length with 1/4-inch inside diameter ends for precise fitment in heater and coolant routing.

Compatible With select Nissan, Honda, and Acura applications, this molded hose is also approved for marine use and can be used in coolant, water, and air applications. Gates 18132 is an OE-style replacement for vehicles that need a formed hose shape to maintain proper routing around the throttle body and thermostat area.

Detailed Description

Gates Molded Heater Hose 18132 is built to match the routing needs of smaller, tighter-fitting engine compartments where formed hose geometry matters. The EPDM material is suited for heater and coolant service, while the molded design helps maintain the correct path between connection points. This part number is used in applications such as 2013-2016 Nissan NV2500 and NV3500, 2012-2015 Nissan Armada, 2013-2015 Nissan TITAN, 2004-2010 Nissan TITAN, 2003-2005 Honda Pilot, and 2001-2002 Acura MDX.

For buyers searching for a Nissan TITAN throttle body to thermostat hose, a Honda Pilot throttle body to pipe-1 molded heater hose, or an Acura MDX molded coolant hose, Gates 18132 provides the formed profile needed for those specific routes. The same part number also appears in interchange listings for related applications.

Common Problems This Hose Can Address

• Cracked or leaking molded heater hose at the throttle body or thermostat connection
• Collapsed or softened hose that no longer holds its formed shape
• Improper routing caused by a straight hose in a tight engine bay
• Coolant seepage from aged EPDM hose material
• Replacement needs for heater, coolant, water, or air hose routing

Installation Notes and Tips

Verify the hose path, end diameters, and centerline length before installation. This molded hose is listed for throttle body to thermostat and throttle body to pipe-1 positions, so match the vehicle routing exactly on your Nissan, Honda, or Acura application. Inspect adjoining fittings and clamps for wear, and confirm the hose is seated without twist or kinks after installation.

Quality Assurance

Gates manufactures molded coolant and heater hoses to OE-style dimensions for accurate routing in modern engine compartments. Part number 18132 is built from EPDM and follows the molded configuration specified for the listed applications.
