• Worth knowing Where a diagram shows several similar items on one assembly, the difference between them is normally length, shoulder or handedness.

Replace the seals with the valve. The old O-rings will not seal twice, and a leak here is often blamed on the new part.

Check the number on the part you are removing before ordering. If it is worn off, send the VIN and a photo and we will match it.
