Detailed Product Description
The Gates Molded Heater Hose 19168 is part of the Molded Heater Hose product line, which focuses on delivering pre-formed hoses that match original equipment specifications. This hose is made from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and automotive fluids, making it suitable for HVAC heater core connections. The molded construction ensures a precise shape that fits the HVAC system without the need for additional bending or shaping, reducing installation time and potential leaks.
With a centerline length of 19.7 inches (500 mm) and an inside diameter of 0.63 inches (16 mm) on both ends, this hose is engineered to maintain proper coolant flow and system pressure. The absence of quick connect fittings and branches simplifies the hose design, focusing on durability and straightforward replacement.
Applications and Common Issues Addressed
- Replacement of cracked or leaking heater hoses in Dodge Ram 2500 and Ram 3500
- Resolving coolant leaks causing insufficient cabin heating in Toyota Sequoia and Tundra
- Addressing hose degradation due to heat and chemical exposure in HVAC systems
- Preventing coolant loss and overheating related to faulty heater hoses
- Ensuring proper coolant flow to the heater core for consistent vehicle interior temperature
Installation Notes and Tips
When installing the Gates Molded Heater Hose 19168, ensure the vehicle is cool and the cooling system is depressurized.
