2001 Chevrolet Venture Parts Questions & Experts Answers

• Q: How to inspect the terminal post, insulator, and spark plug for damage and ensure proper operation on 2001 Chevrolet Venture?

  A: Test the terminal post for damage making sure it does not have any bends while also inspecting its looseness by twisting it; the post should stay in place. An inspector must check the insulator for any presence of flashover combined with carbon tracking and soot that results from electrical charge travelling between the terminal post and the ground. The Spark Plug boot must be checked for damage while the Cylinder Head area around the Spark Plug recess needs inspection for any presence of oil, coolant or water because water in the boot can create ground arcing. Check the insulator for any cracks which would enable electrical charge to arc instead of passing through the electrodes (3, 4). Check the center electrode against the side electrode distance to confirm it adheres to ignition system specifications since too wide spacing can restrict Spark Plug performance. Insufficient Spark Plug torque according to ignition system specifications will cause operational problems yet excessive torque may damage the insulator through cracking. You should inspect for tracking near the insulatortip instead of the center electrode (3) and verify the condition of both the center electrode and side electrode through Spark Plug shaking to detect internal damage; if your Spark Plug rattles it indicates internal damage while a loose center electrode (3) weakens spark intensity. Examine the area between electrodes (3 and 4) due to possible deposition that shortens or removes gap size. Also verify that platinum pads (3 and 4) are present and not damaged. The examination of the Cylinder Head Spark Plug recess area should be performed to check for debris since damaged or dirty threads stop the Spark Plug from seating properly during installation.
