2001 Buick Regal Parts Questions & Experts Answers

• Q: How to replace the timing chain and sprockets (L36) on 2001 Buick Regal?

  A: Start by removing the engine front cover before you align timing marks between the sprockets and position them as closely together as the marks will allow. First remove the Timing Chain dampener then proceed to remove the camshaft sprocket bolt and camshaft sprocket and Timing Chain. A plastic mallet blow to the lower sprocket edge should help free it if it does not detach effortlessly. Access the camshaft thrust plate and its bolts becomes possible by first removing the Crankshaft sprocket and then potentially the balance shaft drive gear. Test components to check for damage together with an inspection for wear. Adjust the camshaft by rotating it until its timing mark aligns straight down using the sprocket which is installed only temporarily while the number one Piston sits at top dead center. Beginning the balance shaft driven gear installation requires stopping the balance shaft from rotation before torquing the bolt to 22 nm (16 ft. Lbs.) using the j 36660-a electronic torque angle meter to add an extra 70-degree rotation. After positioning the camshaft thrust plate in place install its bolts first to 15 nm (11 ft. Lbs.) before mounting the balance shaft drive gear. Place the balance shaft drive gear timing marks alongside the balance shaft driven gear marks before adding the Crankshaft sprocket, Timing Chain and sprocket while working to minimize the distance between the marks. Use j 36660-a to rotate the camshaft sprocket bolt 90 degrees after tightening it to 100 nm (74 ft. Lbs). The Timing Chain dampener goes next as you tighten the 22 nm (16 ft. Lbs.) bolt. To verify mark alignment, perform two engine revolutions afterwards you can install the engine front cover.
