Timing Chain Guide – GM (25190534)

Timing Chain Guide is part of the drive path between two shafts. Gears are lapped as a pair at the factory, which is why mixing a new gear with a worn mate usually produces noise.

Replace the Timing Chain Guide when backlash or tooth pattern is out of specification, or when the fluid carries metallic paste. Setting the pattern correctly on assembly matters as much as the part.

This Timing Chain Guide is listed under part number 25190534, filed under Camshafts & Timing. If the original number is unreadable, send us the VIN and we will confirm the reference before dispatch.

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