Step 1: Determine whether or not the A/C Condenser in the vehicle is affected by this service program by verifying the part number of the currently installed part: • Remove the 2 retaining clips and the air intake duct to gain access to the part number label. • Confirm the A/C condenser assembly part number on the label as shown below. • Is the A/C Condenser part number 73210SG010? (Refer to table below.) YES: This A/C condenser IS affected and must be replaced. Proceed to STEP 2. NO: A/C Condensers with part numbers 73210SG011, 73219SG000 or a BLACK MARK as shown in the table below are the latest versions and DO NOT require replacement.

REMINDER: Any recovered refrigerant is to be recycled and reused whenever possible. • Remove the coolant reservoir tank. STEP 3: After removing the retaining clips, remove the grille bracket. STEP 4: Remove the bolts securing the piping to the A/C Condenser assembly. IMPORTANT: Using the proper size plastic plug or electrical tape, seal the ends of the removed pipes to prevent foreign matter and moisture from entering the “opened” A/C system. STEP 5: Remove the bolts securing the two (2) upper radiator support brackets.

STEP 7: CAREFULLY lift the A/C Condenser out while using CAUTION to not damage the radiator fins. Any damaged / bent fins should be CAREFULLY straightened using a small flat head screwdriver or a radiator fin comb tool. STEP 8: Add 40cc of refrigerant oil to the new A/C condenser using the suction pipe connection point as shown. STEP 9: Fit the new o-rings to the piping connection points. REMINDER: Always lubricate the new o-rings with refrigerant oil. STEP 10: Reassemble in reverse order of removal. NOTE: Use Special Tool 73099SG000 to properly tighten and torque the two (2) bottom A/C Condenser bolts. IMPORTANT CAUTION: In some rare cases, the mounting hardware for the radiator can become corroded. This may cause damage to the mounting hardware during removal. If this situation occurs, replace the necessary hardware. 902460010 Bulletin Number: WRB-21R; Revised: 11/11/21 Page 6 of 10 Continued… 904586001 NOTE: USE CAUTION when replacing the mounting nuts on the radiator. Using a small amount of spray lubricant (e.g. WD-40 or equivalent) is recommended to reduce chances of damaging the three nut positioning claws circled in the image below. If the claws are damaged, replace the radiator assembly. Tightening Torque Specifications: • High and low-side piping connection bolts to A/C Condenser: 7.5Nm (5.5 ft. lbs. / 66 inchpounds) • Upper radiator support bracket bolts: 12Nm (9 ft. lbs.) • Bottom A/C Condenser bolts (using Special Tool 73099SG000): Use the torque wrench calculation formula supplied below.

To: All Subaru Retailers From: Subaru of America, Inc. – Service Operations Department Date: April 21, 2021 Re: WRB-21 Forester Condenser Parts Scrapping Subaru policy states that retailers are responsible for retaining all parts that have been replaced in association with a Recall/Campaign claim for at least 14 days from the claim credit date. There has been some concern expressed with the amount of space the condensers are taking up in the retailer Parts Departments when WRB-21 recalls are performed. As a result, we will be making a policy exception specifically for the WRB-21 recall. Effective today, retailers can scrap condenser parts replaced under the WRB-21 recall on or immediately after the claim credit date, rather than holding the part for an additional 14 days. This applies to only to condensers that are replaced to complete the WRB-21 recall on an affected vehicle. The parts scrapping policy outlined in section 15.2.5 of the Claims Policies and Procedures Manual applies to all other parts replaced when performing any other recall/campaign. Should you have any questions, please contact the Claims Helpline 866-782-2782.
