Engine Coolant Pipe O-Ring – GM (55354068)

Engine Coolant Pipe O-Ring carries fluid along a routing shaped for the chassis it was built for. A line that is close but not exact chafes against something and fails at the wear point rather than at a fitting.

Replace the Coolant Pipe O-Ring when you find a weep at a crimp, a soft spot under a clamp, or a rub mark against a bracket. Fit new clips with the line: an unsupported line fails again at the same place.

For this Coolant Pipe O-Ring the reference is 55354068, in our Seals & O-Rings range. Compare it with the number on the part you are replacing rather than with a photograph.

This is GM dealer-sourced stock rather than an equivalent, so the number on the Coolant Pipe O-Ring traces straight back to the manufacturer.
