Chevrolet Discharge Hose: 4812852
The Chevrolet and Cadillac applications listed above feature a 7SAS17C control valve style compressor vs. earlier 2000-2014 models that featured a 10S20F style compressor. Refer to gpd Tech Tip #9, “Electronically Controlled Variable Drive Compressors” for more information on control valve compressors and how diagnosis varies from other compressor styles.
THE PROBLEM
The discharge hose in the 2014-2018 Chevrolet/Cadillac applications listed above has been identified as a high replacement component. These OE discharge hose has been known to crack and leak due to vibration at the bend of the hose. The OE repair is to replace the discharge line with a modified line, Delco #15-34651, and an additional bracket, GM #23264893, between the new discharge line and the suction line.

gpd has redesigned the discharge hose (gpd #4812852) to make it more durable and will not interfere with other components of the system. Instead of aluminum, gpd uses steel. The hose is a direct replacement that will not require any brackets or modifications to the original design.
gpd SOLUTION
gpd offers a direct fit replacement discharge hose, 4812852, made of steel. Compared to the original aluminum design, gpd’s steel design is more durable and does not require modification or additional bracket.

INSTALLING DISCHARGE HOSE 4812852
1. Ensure the system is clean and free of debris. Ensure that the new sealing washers are used on the suction line before fitting the discharge line with new sealing washes on top. These can be found in gpd rapid seal kit 1321337.
|
2. Place gpd discharge hose 4812852 on top of the suction hose. As these are held down with only one bolt, ensure they interlink correctly and tighten bolt using manufacturer’s specifications.
|
3. gpd has retained the muffler to keep the system quiet. Use either the old transducer from the old discharge line or if damaged, use gpd transducer 1711513 on the new discharge line.
|
4. Remove the cap on the port located on the muffler. Screw on the transducer and connect the electrical plug.
