# OIL PRESSURE SWITCH TWO COMBINATIONS USED

#### VEHICLES AFFECTED: 1983 And 1984 'J' Series Cars Equipped With 1.8L Engines

1983 and 1984 'J'Series vehicles equipped with 1.8 litre engines have two oil pressure switch and adapter combinations. One combination uses a straight metric thread switch and adapter. The other combination, switch 25036455 and adapter 10021730 are tapered metric thread and have a seal (10021731) installed between them.

Only the tapered metric thread switch and adapter are available for service. Because it may be necessary to order the switch, adapter and seal together, or individually, proper part identification is necessary before ordering.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
