About part number 31353364

A headlight washer cover is a small exterior trim panel that sits on the front bumper. It clips over the retractable washer nozzle mechanism, keeping the bumper surface flush and protecting the washer spray nozzle from road dirt and weather when it is not in use. When the system operates, fluid pressure pushes the nozzle out through the opening, and the cover closes flat again once spraying is complete.

To ensure this part is correct for your vehicle, you must check that the manufacturer part number 31353364 matches the number stamped on your original item. On plastic body trim of this type, the part number is usually moulded directly into the plastic on the reverse side. Matching this exact number is the only way to confirm correct fitment and alignment on the bumper.

These covers are commonly replaced because they have been knocked off, lost, or damaged by impact. If the cover was lost during operation, you may also need to inspect or replace the washer nozzle or the telescopic actuator unit underneath to ensure the mechanism still extends and retracts smoothly.

About this kind of part: headlamp lens covers

A headlamp lens cover is the clear outer face of a headlamp, supplied on its own so that a lamp with a sound interior can be saved rather than replaced. It is moulded polycarbonate with a hard coat on the outside, and that coat is what fails: the plastic itself stays sound while the surface clouds, yellows and crazes under years of sunlight and stone blasting. Replacing the lens is a workshop job rather than a bolt-on repair, because the lamp has to be opened and resealed.

Why people replace one

  • The lens has gone yellow or milky, which cuts the light output and fails an inspection, while the inside of the lamp is still clean and sound.
  • A stone has starred or cracked the lens but the reflector and the interior are undamaged.
  • An earlier polish has taken the hard coat off, and the surface has clouded again within months because there is nothing left to protect it.
  • A complete replacement lamp costs several times the lens, and the lamp otherwise works.
  • The lens has been sanded or lacquered by hand and the finish is hazy or uneven.

Fitting it

  • The lamp must be opened by softening the factory sealant all the way round, usually with gentle heat, then prised apart without flexing the housing.
  • The old sealant is removed and fresh butyl sealant is laid in the channel before the new lens is pressed home and clamped until it sets.
  • The inside of the reflector must not be touched or wiped. Its coating marks permanently and a fingerprint stays visible once the lamp is lit.
  • Work in a dry, dust-free space and let the lamp cool fully before refitting, or moisture seals inside and shows up as condensation later.
  • This is a job for a workshop or for somebody who has done it before. A lens fitted badly leaks, and a leaking lamp is worse than a cloudy one.

Making sure it is the right one

  • Match the shape to your own lamp exactly, and check the part number of the LAMP rather than of the lens. A lens is made to suit one lamp number.
  • Check the lens pattern. Within one model the bulb, discharge and diode lamps often use lenses that differ in their internal optics while looking similar from the front.
  • Count and compare the locating lugs and the sealing channel against your own lens before committing to opening the lamp.
  • A lens cover is a replacement outer face and not a complete lamp. Nothing behind the lens is included.

What to look for in the photographs

A Sealing channel — The groove around the rim that takes the butyl sealant. It must match the channel on your own housing, or the lamp cannot be sealed.
B Locating lugs — The tabs and pegs around the edge that set the lens in the housing. Count them and compare their positions.
C Internal optics — The prisms and flutes moulded into the inner face. These differ between light sources even where the outer shape looks the same.
D Outer surface — Look across the face at a shallow angle for moulding marks or scuffing picked up in shipping, which a straight-on photograph will not show.
E Edge profile — The outline where the lens meets the housing. Hold it against your own lamp rather than judging by the overall shape.
