Review on 🔧 GM Genuine Parts 12563918 Dipstick Tube: Premium Quality and Perfect Fit by Jason Marquez

Remove 15mm mounting screw. Place the old dipstick tube in a vise. Twist back and forth to release, then pull. Carefully remove the spark plug cap from the second spark plug from the front (passenger side). Climb up to the engine and look straight through the trunk you just removed. You will see a small hole in the engine block about 15cm below the spark plug where you will insert the new hose. Hope this helps someone
