2002 Chevrolet Trailblazer Parts Questions & Experts Answers

• Q: How to replace the Dipstick Tube and oil level indicator on 2002 Chevrolet Trailblazer?

  A: The A/C line bracket nut and attached A/C line bracket need removal before you detach the oil level indicator tube from its stud. You should start by disconnecting the 02 sensor electrical connector from the oil level indicator bracket before you extract the indicator from the tube and pull it from the block while also removing the oil level indicator tube stud. The engine block installation process requires inserting the oil level indicator tube while applying GM P/N 12346004 (Canadian P/N 10953480) sealant to the oil level indicator tube stud threads before tightening it to 10 Nm (89 inch lbs.). Place the reattached A/C line bracket on the oil level indicator tube and fasten it with the nut which requires a torque of 7 Nm (6 inch lbs.). Next, connect the 02 sensor electrical connector followed by installing the oil level indicator into the tube.
