2006 GMC Savana 3500 Timing Cover Parts Questions & Experts Answers

• Q: How to replace the engine front timing cover on 2006 GMC Savana 3500?

  A: Engine front cover replacement begins by removing the Water Pump and crankshaft balancer followed by Oil Pan-to-front cover bolts then front cover bolts which allows you to remove the front cover and gasket that gets discarded. Make sure the engine front cover has no oil or foreign objects before cleaning it thoroughly. After removing the crankshaft oil seal and front cover gasket it is essential to replace them both and follow installation instructions regarding sealant use. Lay a 5 mm (0.20 inch) bead of equivalent sealant gm U.S. P/N 12378190, 20 mm (0.80 inch) long at the engine block junction where it meets the Oil Pan. Then install the new front cover gasket and cover. First tighten all the front cover bolts and Oil Pan-to-front cover bolts until they reach adequate tension while remaining below the maximum tolerance. The front and rear cover alignment tool j41476 helps position the crankshaft front oil seal toward center while matching its tapered elements with machined areas on the front cover. Tighten the Oil Pan to front cover bolts and engine front cover bolts to 25 nm (18 ft. Lbs.), then remove the j41476. To complete the repair you need to install an all-new crankshaft front oil seal and Water Pump.
