If DTC P1326 is present, first perform the bearing clearance inspection with the Engine Bearing Clearance
Tester device (SST KQ231-2T110QQK). This device checks the rod bearing clearance by placing air and
vacuum into the cylinder block. Measure the bearing clearance and follow the instructions in this bulletin.
Refer to the flow chart found on pages 2-4, then follow the appropriate procedure as outlined in this bulletin.
Before conducting the procedure, verify the vehicle is included in the list of affected VINs.
A Vehicle Diagnosis Number (VDN) must be created with or without DTC P1326, after scanning for DTCs, prior
to performing PI2002Y/Z. If a VDN is not created, Warranty claim submission issues WILL occur.

 NOTICE
To assure complete customer satisfaction, always remember to refer to WebDCS Warranty
Coverage (validation) Inquiry Screen (Service → Warranty Coverage → Warranty Coverage Inquiry)
for a list of any additional campaigns that may need to be performed on the vehicle before returning
it to the customer.

ADDITION OF BLUE LOCTITE TO BCT MEASURING POINT
This outline provides information regarding the application of Loctite® Threadlocker Blue 242 to the dial
gauge ‘measuring point’ end included in the Engine Bearing Clearance Tester (BCT) kit SST KQ231
2T110QQK. This extra step helps reduce the possibility of the measuring point tip loosening on the dial
gauge due to repeated use. If measuring tip comes loose, inaccurate BCT measuring readings will result.
This tool remedy should only need to be performed once.
Instructions:
Probe Rod
1.

Unscrew the ‘measuring point’ end (A) from the base of the dial gauge.

2.

Apply one drop of blue Loctite® to the threaded end of the ‘measuring point’.

3.

Reinstall the ‘measuring point’ end back onto the dial gauge finger tight.

4.

Fully insert the dial gauge into the probe rod.

5.

Secure the gauge to the probe rod by tightening the locking wing nut by hand.

6.

Test gauge operation by pressing the lower bar of the probe rod inward and
verify the gauge readings correspond with the movement
