PROBLEM

Show/hide table

Certain 0R0997, 0R1000, 0R1001, 0R1002, 0R1003, 0R1004, 0R1005, and 0R1006 Reman water pumps were discovered to have the cup plug installed up to 3 mm too deep into the housing. This could cause the weep hole to be blocked. If this issue is not corrected, coolant may accumulate inside the weep chamber and bypass the oil seal causing contaminated engine oil.

ACTION REQUIRED

Show/hide table

Inspect the 0R0997, 0R1000, 0R1001, 0R1002, 0R1003, 0R1004, 0R1005, and 0R1006 in dealer parts stock.

Inspection Procedure:

1. Inspect the package date code on the outside of the water pump box. (Image 1) The first nine characters of the date code indicates Month, Day, Year. Disregard the last four digits of the date code. Determine if the date code falls between D09M03Y09 and D24M03Y09 (09 March 2009 thru 24 March 2009).

- If the date code on the package IS between D09M03Y09 and D24M03Y09 (09 March 2009 thru 24 March 2009), proceed to step 2.

- If the date code on the package IS NOT between D09M03Y09P68HL and D24M03Y09P68HL (09 March 2009 thru 24 March 2009), mark the package to indicate the part has been inspected according to PI7#### / REBE5166 and return the part to dealer parts stock. No further rework is needed on these parts.

2. Remove the water pump from the packaging and inspect the cup plug installed in the water pump housing.

- If the cup plug is installed with the top edge of the cup plug nearly flush with the surface of the water pump housing (maximum of 1.25 mm depth), similar to Image2, the cup plug is installed correctly. Return the water pump to the original packaging, mark the package to indicate the part has been inspected according to PI7#### / REBE5166, and return the part to dealer parts stock. No further rework is needed on these parts.

- If the cup plug is installed with the top of edge of the cup plug recessed into the water pump housing more than 1.25mm, similar to Image3, the water pump needs to be reworked. Proceed to Step 3.

Rework Procedure:

NOTE: Be careful not to damage the cup plug when removing it from the water pump housing, the part will be reused.

3. Place a flat blade screwdriver against the inside edge of the cup plug and tap the end of the screwdriver with a hammer. This should turn the cup plug 90 degrees in the bore (Image 4).

4. Remove the cup plug (Image 5).

6. Re-install the cup plug into the bore.

NOTE: The cup plug is to be installed flush with the housing, to a maximum depth of 1.25 mm (Refer to Image 2)

7. Return the water pump to the original packaging, mark the package to indicate the part has been reworked according to PI7#### / REBE5166, and return the part to dealer parts stock.
