BULLETIN NO.: 97-T-13AISSUE DATE: April, 1998
GROUP/SEQ. NO.: HVAC-O1
CORPORATION NO.: 7812O2R
SUBJECT:
Rattle in Engine Compartment at Idle
(Install Foam Rubber to A/C Hose Conduit)
Due to the addition of 1998 model year vehicles, this bulletin supercedes 97-T-13, which should be discarded.
MODELS AFFECTED:
1996-1998 Saturns built according to the following VINs:
^ 1996 Saturns built after and including VIN TZ238241
^ 1997 Saturns except for 1997 vehicles built between VZ3O4167 and VZ314184, which have the foam rubber installed during production
^ 1998 Saturns built before and including VIN WZ128OO3
CONDITION:
The A/C compressor suction hose may contact the transaxle cover and/or battery tray causing a rattle condition at idle.
CAUSE:
The hard nylon conduit of the A/C compressor suction hose contacts adjacent components such as the transaxle cover and battery tray, and during certain conditions (most commonly at idle), an audible underhood noise in the engine compartment is heard. This noise is usually described as a rattle.
CORRECTION:
Remove A/C compressor suction hose conduit, install foam rubber to conduit, and reinstall using the procedures in this bulletin.
PROCEDURES
1. Disconnect front air intake duct assembly at air filter assembly to improve access to A/C compressor suction hose.
2. Remove A/C compressor suction hose conduit from A/C compressor suction hose.
3. Wipe A/C compressor suction hose conduit with alcohol to remove any oil or dirt contamination.
4. Trim a 114.3 x 298.5 mm (4-1/2 x 11-3/4 in.) rectangle piece from a new battery heat shield assembly (P/N 21024475).
5. Apply a generous amount of Kent Industries Stick It Adhesive (P/N 10170) or equivalent to the back side of the foam piece cut from the battery heat shield assembly. (The back side of the foam is the side opposite the smooth side.)
6. Apply a generous amount of Kent Industries Stick It Adhesive (P/N 10170) or equivalent to the A/C compressor suction hose conduit.
7. Allow enough time for the adhesive to flash, then install foam piece to A/C compressor suction hose conduit.
IMPORTANT:
When installing the foam piece to the A/C compressor suction hose conduit, make sure to align the edge of the foam piece to the lengthwise opening in the A/C compressor suction hose conduit as shown in illustration.
8. Trim foam piece as required to fit the length of the A/C compressor suction hose.
9. Lubricate the A/C compressor suction hose with a mild liquid soap to help installation of the A/C compressor suction hose conduit.
NOTICE:
Make sure the A/C compressor suction hose conduit does not contact transaxle electrical wires, or transaxle electrical wire could become damaged.
10. Install the A/C compressor suction hose conduit to the A/C compressor suction hose. Position the A/C compressor suction hose conduit just rearward of the transaxil wire connector. Make sure A/C suction hose conduit does not contact transaxle wires.
11. Reconnect front air intake duct assembly to air filter assembly.
