Question
Hi Tom,
Can you tell me where exactly the oil pressure sending unit is located on my vehicle? Does it require a special socket to change it out? Thank you for your time.

Answer
HI FRED,YOUR OIL PRESSURE SWITCH IS LOCATED BY EITHER BY OIL FILTER OR IN THE REAR SIDE OF ENGEINE BELOW THE POWER STEERING PUMP... THEY DO Make A SPECIAL SOCKET TO REMOVE THE SWITCH.. BUT A THIN WALL DEEP SOCKET WILL WORK...HOPE THE IS HELPS YOU,,TOM...
