  Q: How to replace the camshaft on GMC Savana 1500?

  A: The Camshaft replacement requires beginning with radiator support and engine front cover removal followed by removal of valve lifters. Start by unbolting the Camshaft sensor and sensor bolt then use the Crankshaft to align the timing marks of both the sprockets. Detach bolt number 206 from the Camshaft sprocket while keeping in mind the same diameter of all Camshaft journals to prevent bearing damage. Remove first the bolts (231) with Timing Chain Tensioner (232) from the assembly before taking out the Camshaft sprocket and moving the Timing Chain into position. Use a bolt as a handle to pull out the Camshaft carefully from the engine block after removing each retainer bolt (204) along with retainer (203). A detailed inspection as well as cleaning process should take place on both the Camshaft along with its bearings. After applying clean engine oil on Camshaft journals and bearings you should carefully reinstall the Camshaft into the engine block while removing the bolt. Put the Camshaft retainer (203) into place while its sealing gasket faces the engine block using a clean surface on the gasket. The first design hex head bolts require tightening to 25 nm (18 lb ft) while the second design torx(R) head bolts need 15 nm (11 lb ft). Hang the en 46330 onto the compressed Timing Chain Tensioner guide. Install the Timing Chain Tensioner (232) together with bolts (231) before tightening them to 25 nm (18 lb ft). The location pin of the Camshaft sprocket should match the alignment hole of the sprocket while ensuring proper alignment between the teeth. After sprocket marks of Camshaft and Crankshaft align correctly install the Camshaft sprocket (205) and Timing Chain (208). Begin by installing new Camshaft sprocket bolt (206) while following initial torque of 75 nm (55 lb ft) before applying a secondary 50 degrees of torque. The Camshaft sensor o-ring should be inspected for damage before using an unbroken one as replacement. To conclude the process install the valve lifters followed by the front cover and radiator support.

Pull out Water Pump bolts and extract all Water Pump parts with the gasket built-in. Check for surface damage on both engine block and Water Pump bolt areas before cleaning these surfaces. Install the gasket and water coolant pump but apply teflon pipe sealant gm p/n 12346004 or compatible product to the Water Pump mounting bolts first. Then fasten and torque the bolts to 42 nm (31 ft. Lbs.). Put the Water Pump mounting bolts through their bolt holes after reattaching the heater, by-pass, and radiator hoses to the Water Pump component. Then install the Water Pump Pulley and its bolts but tighten them up to 25 nm (18 ft. Lbs.). Connect these components to complete the assembly: Drive Belt, fan clutch, upper Fan Shroud, coolant tank and the air system parts. Rejoin the negative Battery Cable while adding coolant to the engine system and removing air from the coolant system before checking for any leakages.
