Engine Timing Chain – ACDelco (89060443)

Engine Timing Chain transmits drive at a fixed ratio and is matched to its shaft by tooth count and spline. A single tooth difference changes the ratio and surfaces as a speedometer error or a shift complaint.

Replace the Engine Timing Chain when tooth faces show pitting, when a whine rises with road speed, or when there is metal in the fluid. Gears wear as a set, so replacing half of one usually brings the noise back.

For this Engine Timing Chain the reference is 89060443, in our Camshafts & Timing range. Compare it with the number on the part you are replacing rather than with a photograph.

This is genuine ACDELCO stock, supplied for the Engine Timing Chain with the manufacturer number intact so the reference on the box matches the catalogue.
