How to Align the Camshaft Chain on a Hyundai Elantra?

First, align the "T" marks on the crankshaft sprocket and camshaft sprocket with the fixed marks on the engine. Then, install the chain and adjust the tensioner. Finally, rotate the crankshaft two full turns clockwise and check if the "T" marks are properly aligned.

I've been repairing Hyundai Elantras for many years, and chain alignment is a skilled job. First, remove the valve cover, locate the mark on the crankshaft pulley, and rotate it to the top dead center position of the first cylinder's compression stroke. At this point, check the back of the camshafts—the small dots on both camshafts must face directly upward and align with the markings on the cylinder head surface. The most critical part is avoiding misalignment during rotation; adjustments should be made slowly while the tensioner is loose. After installing the chain, don't rush to start the engine—manually turn the crankshaft two full rotations with a wrench to confirm all marks still align perfectly. Before reinstalling the timing cover, remember to clean the sealing surface and apply specialized sealant. Beginners shouldn't attempt this—last time a DIY owner misaligned by two teeth and bent all the valves.
