Q: How to replace the Lash Adjuster on the left side on GMC Acadia?
A: Start by removing the appropriate Camshaft(s) then rockers and finally lash adjusters on the left-hand side for Lash Adjuster replacement. Maintenance professionals should clean all components including camshafts, rocker arms, and lash adjusters before determining repair or replacement needs. Start with Lash Adjuster installation followed by installing rocker arms before fixing the needed Camshaft(s).
Q: How to replace the Lash Adjusters on GMC Sierra 1500?
A: To replace the valve lifters, first, one should collect the tools: valve lifter remover (J 3049-A). Start by taking off the Intake Manifold and the pushrods while ensuring that the components are seated in a rack to ensure retention for reassembly. Next, unscrew the bolts and the lifter pushrod guide and position the valve lifters in rack upright so that the oil will remain inside. If there are any stuck valve lifters because of gum or varnish deposit in it, use valve lifter remover (J 3049-A) to remove them. Clean the valve lifter bores with a cleaning solvent and shop towel and check them for excessive wear or scoring which may require replacing the engine block. Also inspect the Camshaft for wear or damage removing the Camshaft for further inspection if needed. Replace the lifters as necessary. When re-installing new lifters, apply lubricant to the lifter rollers, and if using lifters for parts that they were used in initially, they were used in their original positions. Go on to install the lifters, then the lifter pushrod guides, ensuring the bolts are torqued to 16 n.m (12 lb ft), then install the pushrods and lastly the Intake Manifold. In new lifters, it is typical for engines to generate a little ticking sound when starting it for the first time; there should be some noise-lessening after slightly increasing the engine rpm to increase oil pressure.
Q: How to replace the Lash Adjusters on GMC Yukon?
A: The process starts with removing both the Cylinder Head and gasket before proceeding with Lash Adjuster replacement. First remove the Lash Adjuster guide bolts (211) then extract the Lash Adjuster guides (210) and adjusters while carefully memorizing the original guide positioning because the notched section needs to align with the engine block's locating tab. Next proceed to extract lash adjusters (209) from guide (210) before marking or organizing replacement parts. The clean-up and inspection of lash adjusters should happen when needed. Reinstalling requires application of clean engine oil on both lash adjusters (209) and engine block Lash Adjuster bores before putting lash adjusters into lifter guides (210). When seating the lash adjusters, position the flat areas on the adjuster tops against the flat areas in the adjuster guide bores before pushing the adjusters fully into position. The engine block gets its lash adjusters and guide (210) installation following fastener caution rules while the guide bolts receive a 12 nm (106 lb in) torque specification. Reinstall the Cylinder Head while also installing the gasket.
