Detailed Description
This Dorman HVAC heater hose fitting, part number 47994, is engineered to match the fit and durability of the original hose fitting used on specified vehicles. The nylon body and 90-degree three-way elbow layout support heater hose routing in tight spaces, while the barb ends provide a secure hose connection for leak-free service. It is a direct replacement for applications such as the Chevrolet Uplander inlet, Pontiac Montana inlet, Buick Terraza inlet, Saturn Relay inlet, and Oldsmobile Silhouette inlet with rear auxiliary A/C. Dorman 47994 is a practical choice when replacing a worn or damaged heater hose fitting on these platforms.
Common Problems This Part Can Address
- Cracked or brittle heater hose fitting material
- Coolant seepage at the heater hose connection
- Damaged barb ends that no longer hold the hose securely

Installation Notes and Tips
Verify the inlet location, hose diameter, and rear auxiliary A/C configuration before installation. Inspect the heater hose ends for wear, swelling, or contamination, and replace any damaged hose sections as needed to maintain a secure seal. Confirm the barb orientation and 90-degree routing match the original part before connecting the hose.
