- Extracts broken dipstick tubes, a common issue on GM 4.8L, 5.3L, 5.7L, 6.0L & 6.2L Engines during engine service
- When the dipstick tube breaks off, a piece remians at entry point, located at the bottom of the engine block (near the oil pan)
- Use the extractor to thread into tube to remove
- Use with #5401 Thread Adapter Tool and any standard thread (5/8″-18 TPI) slide hammer to properly remove the stuck dipstick tube
Instructions
Instructions:
- Raise and safely support the vehicle. Allow access to the broken dipstick tube at the base of the engine block.
- Clean the area around the broken tube thoroughly. Use brake cleaner or solvent on a rag to remove all dirt, oil residue and debris.
- Spray penetrating oil liberally into the open end of the broken tube. Allow time for the oil to penetrate down the tube.
- Thread the extractor down into the broken tube by hand initially. If needed, use a wrench to carefully thread the extractor further into the tube. Do not overtighten.
- Once the extractor is threaded securely into the tube, attach a pry bar or pliers onto the extractor base. Use the pry bar or pliers for leverage to loosen and pry the broken tube up and out.
- For stubborn tubes, attach the CTA 5401 adapter to use with a slide hammer. Use the slide hammer to apply pulling force while turning the extractor to unthread the broken tube.
- Once the broken tube is removed, clean the dipstick tube hole in the engine block thoroughly.
- Install a new replacement tube per manufacturer instructions. Refill engine oil.
