Gates 19755 HVAC Heater Hose - Heater To Pipe-2 or Heater To Tee-1

Gates 19755 Molded Heater Hose Overview

The Gates 19755 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a straight hose will not route correctly. It is formed to match the application and is suitable for coolant, water, and air service, with marine application approval.

Compatible with select Nissan Maxima and INFINITI I30 applications, this molded heater hose supports a clean factory-style routing path in the heater circuit. The Gates Molded Heater Hose line focuses on shaped replacement hoses that follow original equipment geometry for a more precise fit.

Detailed Description

Gates 19755 is a molded HVAC heater hose made from EPDM for durability in coolant-system service. Its 0.75-inch inside diameter at both ends and 34.6-inch centerline length make it a direct-shaped replacement for applications that require a formed hose rather than a universal straight section. This part number 19755 is listed for 1995-1996 Nissan Maxima, Heater To Pipe-2, 1996 INFINITI I30, Heater To Pipe-2, and 1997-1999 Nissan Maxima and 1997-1999 INFINITI I30, Heater To Tee-1.

As part of the Gates Molded Heater Hose product line, this hose is intended to match original routing in compact engine compartments. That makes it a practical choice when replacing a heater hose on a Nissan Maxima or INFINITI I30 and when maintaining factory-style hose alignment matters.

This part cross-references Dayco 88401 for the same application.

What It Helps Address

• Cracked or aged heater hose material
• Coolant leaks at a formed hose section
• Poor hose routing in tight engine compartments
• Replacement needs for a molded heater hose on Nissan Maxima and INFINITI I30 models
• Service on coolant, water, or air hose runs that require OEM-style shaping

Installation Notes and Tips

Verify hose routing, end diameters, and centerline length against the removed part before installation. Because this is a molded hose, correct orientation matters for proper fit in the heater circuit. Inspect adjoining clamps, tees, and pipe connections for wear or corrosion before reassembly.

For fitment reference, this part fits 1995-1996 Nissan Maxima, Heater To Pipe-2; 1996 INFINITI I30, Heater To Pipe-2; 1997-1999 Nissan Maxima, Heater To Tee-1; and 1997-1999 INFINITI I30, Heater To Tee-1.
