Removal and Installation

 CAUTION: Be sure to use electrically conductive water-resistant sealer on the threads of the unit. The pressure switch-type unit used with the indicator system is not interchangeable with the variable resistance-type switch, which is used with the gauge system. Refer to the Master Parts Catalog for proper parts usage. Installation of the wrong part will result in an inoperative oil pressure indicating system and a damaged sender unit, or gauge.

The oil pressure sending units are mounted at the LH front of the engine block on 5.0L, and on the LH rear of the cylinder head on 2.3L.
